video: Add helpers for decoding screen_info
The plain values as stored in struct screen_info need to be decoded before being used. Add helpers that decode the type of video output and the framebuffer I/O aperture. Old or non-x86 systems may not set the type of video directly, but only indicate the presence by storing 0x01 in orig_video_isVGA. The decoding logic in screen_info_video_type() takes this into account. It then follows similar code in vgacon's vgacon_startup() to detect the video type from the given values. A call to screen_info_resources() returns all known resources of the given screen_info. The resources' values have been taken from existing code in vgacon and vga16fb. These drivers can later be converted to use the new interfaces. v2: * return ssize_t from screen_info_resources() * don't call __screen_info_has_lfb() unnecessarily Signed-off-by: Thomas Zimmermann <tzimmermann@suse.de> Reviewed-by: Javier Martinez Canillas <javierm@redhat.com> Link: https://patchwork.freedesktop.org/patch/msgid/20240212090736.11464-2-tzimmermann@suse.de |

RISC-V SoC drivers for v6.8

firmware: microchip: add PolarFire SoC Auto Update support
Add support for Auto Update reprogramming of the FPGA fabric on PolarFire SoC, using the fw_upload mechanism a la the intel-m10-bmc-sec-update driver. This driver only writes the image to the spi flash & performs validation on it, as the entire FPGA becomes unusable during the actual reprogramming of a bitstream. To initiate the reprogramming itself, a device reset is required. The SBI SRST extension's "cold reboot" can trigger such a device reset, provided corresponding support has been enabled in the HSS (Hart Software Services), the provider of SBI runtime services on PolarFire SoC. While this is a driver responsible for the reprogramming of an FPGA, there is no dynamic discovery of devices involved, as runtime reconfiguration is not possible due to the device reset requirements. Therefore FPGA manager subsystem is not used by this driver and the FPGA subsystem maintainers were unwilling to accept it there. Signed-off-by: Conor Dooley <conor.dooley@microchip.com> |

firmware: Add support for Qualcomm UEFI Secure Application
On platforms using the Qualcomm UEFI Secure Application (uefisecapp), EFI variables cannot be accessed via the standard interface in EFI runtime mode. The respective functions return EFI_UNSUPPORTED. On these platforms, we instead need to talk to uefisecapp. This commit provides support for this and registers the respective efivars operations to access EFI variables from the kernel. Communication with uefisecapp follows the Qualcomm QSEECOM / Secure OS conventions via the respective SCM call interface. This is also the reason why variable access works normally while boot services are active. During this time, said SCM interface is managed by the boot services. When calling ExitBootServices(), the ownership is transferred to the kernel. Therefore, UEFI must not use that interface itself (as multiple parties accessing this interface at the same time may lead to complications) and cannot access variables for us.

firmware: qcom_scm: Add support for Qualcomm Secure Execution Environment SCM interface
Add support for SCM calls to Secure OS and the Secure Execution Environment (SEE) residing in the TrustZone (TZ) via the QSEECOM interface. This allows communication with Secure/TZ applications, for example 'uefisecapp' managing access to UEFI variables. For better separation, make qcom_scm spin up a dedicated child (platform) device in case QSEECOM support has been detected. The corresponding driver for this device is then responsible for managing any QSEECOM clients. Specifically, this driver attempts to automatically detect known and supported applications, creating a client (auxiliary) device for each one. The respective client/auxiliary driver is then responsible for managing and communicating with the application. While this patch introduces only a very basic interface without the more advanced features (such as re-entrant and blocking SCM calls and listeners/callbacks), this is enough to talk to the aforementioned 'uefisecapp'.

arch: Remove Itanium (IA-64) architecture
The Itanium architecture is obsolete, and an informal survey [0] reveals that any residual use of Itanium hardware in production is mostly HP-UX or OpenVMS based. The use of Linux on Itanium appears to be limited to enthusiasts that occasionally boot a fresh Linux kernel to see whether things are still working as intended, and perhaps to churn out some distro packages that are rarely used in practice. None of the original companies behind Itanium still produce or support any hardware or software for the architecture, and it is listed as 'Orphaned' in the MAINTAINERS file, as apparently, none of the engineers that contributed on behalf of those companies (nor anyone else, for that matter) have been willing to support or maintain the architecture upstream or even be responsible for applying the odd fix. The Intel firmware team removed all IA-64 support from the Tianocore/EDK2 reference implementation of EFI in 2018. (Itanium is the original architecture for which EFI was developed, and the way Linux supports it deviates significantly from other architectures.) Some distros, such as Debian and Gentoo, still maintain [unofficial] ia64 ports, but many have dropped support years ago. While the argument is being made [1] that there is a 'for the common good' angle to being able to build and run existing projects such as the Grid Community Toolkit [2] on Itanium for interoperability testing, the fact remains that none of those projects are known to be deployed on Linux/ia64, and very few people actually have access to such a system in the first place. Even if there were ways imaginable in which Linux/ia64 could be put to good use today, what matters is whether anyone is actually doing that, and this does not appear to be the case. There are no emulators widely available, and so boot testing Itanium is generally infeasible for ordinary contributors. GCC still supports IA-64 but its compile farm [3] no longer has any IA-64 machines. GLIBC would like to get rid of IA-64 [4] too because it would permit some overdue code cleanups. In summary, the benefits to the ecosystem of having IA-64 be part of it are mostly theoretical, whereas the maintenance overhead of keeping it supported is real. So let's rip off the band aid, and remove the IA-64 arch code entirely. This follows the timeline proposed by the Debian/ia64 maintainer [5], which removes support in a controlled manner, leaving IA-64 in a known good state in the most recent LTS release. Other projects will follow once the kernel support is removed.

firmware: mediatek: Add adsp ipc protocol interface
Some of mediatek processors contain the Tensilica HiFix DSP for audio processing. The communication between Host CPU and DSP firmware is taking place using a shared memory area for message passing. ADSP IPC protocol offers (send/recv) interfaces using mediatek-mailbox APIs. We use two mbox channels to implement a request-reply protocol.

sysfb: Enable boot time VESA graphic mode selection
Since switch to simplefb/simpledrm VESA graphic mode selection with vga=
kernel parameter is no longer available with legacy BIOS.
The x86 realmode boot code enables the VESA graphic modes when option
FB_BOOT_VESA_SUPPORT is enabled.
This option is selected by vesafb but not simplefb/simpledrm.
To enable use of VESA modes with simplefb in legacy BIOS boot mode drop
dependency of BOOT_VESA_SUPPORT on FB, also drop the FB_ prefix. Select
the option from sysfb rather than the drivers that depend on it.
The BOOT_VESA_SUPPORT is not specific to framebuffer but rather to x86
platform, move it from fbdev to x86 Kconfig.

qcom_scm: hide Kconfig symbol
Now that SCM can be a loadable module, we have to add another dependency to avoid link failures when ipa or adreno-gpu are built-in: aarch64-linux-ld: drivers/net/ipa/ipa_main.o: in function `ipa_probe': ipa_main.c:(.text+0xfc4): undefined reference to `qcom_scm_is_available' ld.lld: error: undefined symbol: qcom_scm_is_available >>> referenced by adreno_gpu.c >>> gpu/drm/msm/adreno/adreno_gpu.o:(adreno_zap_shader_load) in archive drivers/built-in.a This can happen when CONFIG_ARCH_QCOM is disabled and we don't select QCOM_MDT_LOADER, but some other module selects QCOM_SCM. Ideally we'd use a similar dependency here to what we have for QCOM_RPROC_COMMON, but that causes dependency loops from other things selecting QCOM_SCM. This appears to be an endless problem, so try something different this time: - CONFIG_QCOM_SCM becomes a hidden symbol that nothing 'depends on' but that is simply selected by all of its users - All the stubs in include/linux/qcom_scm.h can go away - arm-smccc.h needs to provide a stub for __arm_smccc_smc() to allow compile-testing QCOM_SCM on all architectures. - To avoid a circular dependency chain involving RESET_CONTROLLER and PINCTRL_SUNXI, drop the 'select RESET_CONTROLLER' statement. According to my testing this still builds fine, and the QCOM platform selects this symbol already.

firmware: cs_dsp: add driver to support firmware loading on Cirrus Logic DSPs
wm_adsp originally provided firmware loading on some audio DSP and was implemented as an ASoC codec driver. However, the firmware loading now covers a wider range of DSP cores and peripherals containing them, beyond just audio. So it needs to be available to non-audio drivers. All the core firmware loading support has been moved into a new driver cs_dsp, leaving only the ASoC-specific parts in wm_adsp.

Qualcomm driver updates for v5.15
This fixes the "shared memory state machine" (SMSM) interrupt logic to avoid missing transitions happening while the interrupts are masked. SM6115 support is added to smd-rpm and rpmpd. The Qualcomm SCM firmware driver is once again made possible to compile and load as a kernel module. An out-of-bounds error related to the cooling devices of the AOSS driver is corrected. The binding is converted to YAML and a generic compatible is introduced to reduce the driver churn. The GENI wrapper gains a helper function used in I2C and SPI for switching the serial engine hardware to use the wrapper's DMA-engine. Lastly it contains a number of cleanups and smaller fixes for rpmhpd, socinfo, CPR, mdt_loader and the GENI DT binding. -----BEGIN PGP SIGNATURE----- iQJPBAABCAA5FiEEBd4DzF816k8JZtUlCx85Pw2ZrcUFAmEa29wbHGJqb3JuLmFu ZGVyc3NvbkBsaW5hcm8ub3JnAAoJEAsfOT8Nma3FFnMP/A2Od7JYhdjH7sfc3i3B 0zws88lT7XTo9KSMpLFrQg1Qzp3ELDMfVhS2CpsekZn1g7s6RGnbQrh2Mac9Yh4z +7e4YLhoMxEkdbEVvbVRIX4parFWD/KxUdkyXM8gKZntJzOFl6VY5V8aKi+7IO+/ CdWHvELDVXMe2LkBd3lKE1AlS2MjkohXpFKgRwkY4r2nVXwqYTdkfJvXdGdhECGr ld4ZIvIR6ERLmVpGvTxdU5W0z2xsLTbPYDPSv6mPkWqDYSOyXV3zABV1fSkH28ot wIoesHyI3vL4/LNIlHn+tcWj1Ou8hSzxZmxfq7cdKbkfwPLCWE5D8+HEO4kmbFiF 5Dds+oxvKSFpf/wppK7bUSEd9Q+dKsrFt2mdWy/sYRe1EaEv5sFBgE0rV3+c6ykL tptUEFlaB2si7PKSpKje8czHn4Akuc6BwT6xovZZ72K8CNz9D71etSkoNLLXa54d bJibw2eNTT1EOACC/FPBO9AS11Icm6wszn/dcaSwaSPGQ6cR3lvAwHqzDFMGHp+x L+iojgnZoHykFhQjGuGrI3yTHOpp0MCNxRoN7DlFwm7KLKVHqeqg+xHXtV9sJer8 iAhY/uepLRxc1oC5Z+Ejx1gABmKycXtzKQ9ecwTclrk66ampWQBlv5+Bxd5w/hux ZR96mJPmpk1WKOX3FAgdeaaP =88qN -----END PGP SIGNATURE----- gpgsig -----BEGIN PGP SIGNATURE----- iQIzBAABCgAdFiEEo6/YBQwIrVS28WGKmmx57+YAGNkFAmEdDA4ACgkQmmx57+YA GNmAmw//WfdprWl2SJGfyojhDeeUq6ZeNesMFBabFss7Ar++szhyFSu3bqlyH6WC ZgPOZOJakKQq2EGKNm7RuEgeR8sEUs9czetNO8AqVy1szlhqnUKhG0OO+uLqRLQn Hvf1fc+uG3xeaFP0/Q/4fuG+GL1fnmXIJWl0nZFUGfWyQ3mxxm5fLq1DM27KAzP1 eKMqtCh3F0qHMWZTJd084LO2XXyUTVVBbXAQKX/IQmH6+BK3Q2YMToo/919HCnZs XfgcdKuB/fOfi1n+PgGNODdTJ/Uy10WkSALZHlzKfr77AUCs9+RWxdkogCmACJBs IhNoZ/6D6a6kCIEuaEjHtNsMAVoG0bYpaB9vFLhJgF4wfdCd+DuOXkCy9B7vI4/8 7/SKArKYrG1sPlhDGFaWZjWEFBCGycDDsHQ4T2ecZ5d3f+Kuimgx7NLYhKRHPI+9 8QVJwNbIGrNXjwIn6S0AeqDLoXIzMmAbNvuX1lFz0OyEkbgDYPSuUPmKYoKh0VL5 +aTPYANbKxfF7nIPxfN580yjQGZmJmctyhkqnavEB6HdNySO2/oM5F2uGRVdVKnv 5HaPLqWZf2PffjAg+bU3O3bBlYRdIpEaKaa1eHFIMTgK7nlcvFESWWtwg+IBKdqY JI3Kkg5PP3jxqxybzgFPE298vI1G6/so2A12HBi0dl28XheK+wM= =dS58 -----END PGP SIGNATURE----- Merge tag 'qcom-drivers-for-5.15' of git://git.kernel.org/pub/scm/linux/kernel/git/qcom/linux into arm/drivers Qualcomm driver updates for v5.15 This fixes the "shared memory state machine" (SMSM) interrupt logic to avoid missing transitions happening while the interrupts are masked.

drivers/firmware: fix SYSFB depends to prevent build failures
The Generic System Framebuffers support is built when the COMPILE_TEST
option is enabled. But this wrongly assumes that all the architectures
declare a struct screen_info.
This is true for most architectures, but at least the following do not:
arc, m68k, microblaze, openrisc, parisc and s390.
By attempting to make this compile testeable on all architectures, it
leads to linking errors as reported by the kernel test robot for parisc:
All errors (new ones prefixed by >>):
hppa-linux-ld: drivers/firmware/sysfb.o: in function `sysfb_init':
(.init.text+0x24): undefined reference to `screen_info'
>> hppa-linux-ld: (.init.text+0x28): undefined reference to `screen_info'
To prevent these errors only allow sysfb to be built on systems that are
going to need it, which are x86 BIOS and EFI.
The EFI Kconfig symbol is used instead of (ARM || ARM64 || RISC) because
some of these architectures only declare a struct screen_info if EFI is
enabled. And also, because the SYSFB code is only used for EFI on these
architectures. For !EFI the "simple-framebuffer" device is registered by
OF when parsing the Device Tree Blob (if a DT node for this was defined).
Fixes:

drivers/firmware: consolidate EFI framebuffer setup for all arches
The register_gop_device() function registers an "efi-framebuffer" platform
device to match against the efifb driver, to have an early framebuffer for
EFI platforms.
But there is already support to do exactly the same by the Generic System
Framebuffers (sysfb) driver. This used to be only for X86 but it has been
moved to drivers/firmware and could be reused by other architectures.
Also, besides supporting registering an "efi-framebuffer", this driver can
register a "simple-framebuffer" allowing to use the siple{fb,drm} drivers
on non-X86 EFI platforms. For example, on aarch64 these drivers can only
be used with DT and doesn't have code to register a "simple-frambuffer"
platform device when booting with EFI.
For these reasons, let's remove the register_gop_device() duplicated code
and instead move the platform specific logic that's there to sysfb driver.

drivers/firmware: move x86 Generic System Framebuffers support
The x86 architecture has generic support to register a system framebuffer
platform device. It either registers a "simple-framebuffer" if the config
option CONFIG_X86_SYSFB is enabled, or a legacy VGA/VBE/EFI FB device.
But the code is generic enough to be reused by other architectures and can
be moved out of the arch/x86 directory.
This will allow to also support the simple{fb,drm} drivers on non-x86 EFI
platforms, such as aarch64 where these drivers are only supported with DT.

While not ideal in some cases its the only safe way I can find to avoid build errors without having those drivers select QCOM_SCM and have to force it on (as QCOM_SCM=n can be valid for those drivers). Reviving this now that Saravana's fw_devlink defaults to on, which should avoid loading troubles seen before.

Arm Firmware Framework for ARMv8-A(FFA) interface driver
The Arm FFA specification describes a software architecture to leverages the virtualization extension to isolate software images provided by an ecosystem of vendors from each other and describes interfaces that standardize communication between the various software images including communication between images in the Secure world and Normal world. Any Hypervisor could use the FFA interfaces to enable communication between VMs it manages. The Hypervisor a.k.a Partition managers in FFA terminology can assign system resources(Memory regions, Devices, CPU cycles) to the partitions and manage isolation amongst them. This is the initial and minimal support for the FFA interface to enable communication between secure partitions and the normal world OS. -----BEGIN PGP SIGNATURE----- iQIzBAABCAAdFiEEunHlEgbzHrJD3ZPhAEG6vDF+4pgFAmC19HAACgkQAEG6vDF+ 4pijcw//XugK+jFEN7fA6eFzE7OeGt1xPG2mhG5TF1jtvQv2TQlij50V8evOgJmd kM3h5pUeEWMt4XrF0I2TlLOglBHLpFbU253kRPRC7zeYxK+AzD6TxtABKZ+eykAk OEQisX9FMp/h1rnnvu/OqT7l2AH/pZkVIwc2GQi6h+BvQzUq/NPanuuT+rS00U2E lLfZ98MQIjoUSDKr6r0C83gt8BlUWR62jkIkhsLycwFFouhWrdewXptfOntD4wIs 1pDRi4+qdZLbOeFCLxHR9NfMTdGdnBY//P8NwmnSYV6YnbtVcgwvwyRqMAC6ElJM Lk+AuqJS+RSCdyqQerjkvVMNSQx778nPsmzEMteOyLCAfr2kXhQ84FfqaJpFBDsJ GQUUW8H5runR2P4p2Q3Tql9tTt7AhrOuO0iUIxBu5cq4YRBPMBamtRbquJtYN+VH 9ggV4ygbkq4BIKYaBFaVffHOg0ygbvDTkXv/09wRmcGNH12y9AeuLyumhwcWxV0Z Kk0bjEieTjvisrshOeKOp5eOuhyixhFJNcffAOIos3KIkuQ1ivAL7cIig9fWF+k0 AbqOTvX4dVSdIKBi+Q8op2CZ1gyDi80P43MstTgKlbZ8AN2YWxa9S3Iw27D4gY8u tIN8PqkB2NctwQecVcGv58JyDlqTRnCcuole7fJWr3iGRdGvyV4= =DQ7A -----END PGP SIGNATURE----- gpgsig -----BEGIN PGP SIGNATURE----- iQJDBAABCgAtFiEElf+HevZ4QCAJmMQ+jBrnPN6EHHcFAmDI23cPHG9sb2ZAbGl4 b20ubmV0AAoJEIwa5zzehBx3uCcP/37GON7dD4zlic7idjGb6Wh5VuaaCSkKJDGc J7KDji52tvYVzNiqlTJu4qgTzWEIX3RLGqKHjeZHBDUwuHoWZFOTtVAU0d3xLVw1 gXa9LQypRQ094pZ4/5ClaiBV2tiQB2E8j/jppynG+8XpOUDhu5rFD+dUpOhQwqW+ REs+t1xDuGItcoweJj7ufXw+ZLgoLkbRnU7YniPQe4awS8Ml6lwDi1Rj7CXHmpW4 5AMA1FLovAZ9Y0Dyy3MVOkfHTP/LVP6LPLxcSUc6xkBT9We76WgiHPMtzvNiwSAV ZLTua2cB9OdYt1ZGB40x4XDEZs85L8dGSSRXsARkcX+ImR3rLLOcomdW5QrD7Hgr 1FtoAed13g5cxfiOizjpXLCEl6qxeW3lQ9au4FQ5xCasS7LM5tM/YuiyrafHu+Ep yVNgy35pBNjgh0NmGCGtrH7H9d/n7kdMgTNXHVkD6GW8qxXKEVfVVtwATSRJMRTV 1bjxXjA2B7u91xAnWm874X6SLVYgxRXtHUR4EMxWoSATNAL4pvTNfGz6Wwt1QD1D ZJ8wqjYKhdEnKPqjtUW7iFYrbUd550B9FXwu8f3Uaau8/ON9P+t63C1XPdmyZA57 CQMufO8TaXJ2ARDVxzO5dyYhgqN5Ew2DvDj/qmlGz26mF25JmdigeuRBplNF302+ wj3e47y6 =TfmE -----END PGP SIGNATURE----- Merge tag 'arm-ffa-5.14' of git://git.kernel.org/pub/scm/linux/kernel/git/sudeep.holla/linux into arm/drivers Arm Firmware Framework for ARMv8-A(FFA) interface driver The Arm FFA specification describes a software architecture to leverages the virtualization extension to isolate software images provided by an ecosystem of vendors from each other and describes interfaces that standardize communication between the various software images including communication between images in the Secure world and Normal world.

firmware: arm_ffa: Add initial FFA bus support for device enumeration
The Arm FF for Armv8-A specification has concept of endpoints or partitions. In the Normal world, a partition could be a VM when the Virtualization extension is enabled or the kernel itself. In order to handle multiple partitions, we can create a FFA device for each such partition on a dedicated FFA bus. Similarly, different drivers requiring FFA transport can be registered on the same bus. We can match the device and drivers using UUID. This is mostly for the in-kernel users with FFA drivers.

issues with missing resources and unnecessary deferred probe
- ti-sysc debug option can now detect more devices
- ti-sysc now warns if an old incomplete devicetree data is found as we
now rely on it being complete for am3 and 4
- soc init code needs to check for prcm and prm nodes for omap4/5 and dra7
- omap-prm driver needs to enable autoidle retention support for omap4
- omap5 clocks are missing gpmc and ocmc clock registers
- pci-dra7xx now needs to use builtin_platform_driver instead of using
builtin_platform_driver_probe for deferred probe to work

Note that __arm_smccc_smc is defined when HAVE_ARM_SMCCC is y.
So add dependency on HAVE_ARM_SMCCC in QCOM_SCM configuration.

arm64: socfpga: merge Agilex and N5X into ARCH_INTEL_SOCFPGA
Agilex, N5X and Stratix 10 share all quite similar arm64 hard cores and SoC-part. Up to a point that N5X uses the same DTSI as Agilex. From the Linux kernel point of view these are flavors of the same architecture so there is no need for three top-level arm64 architectures. Simplify this by merging all three architectures into ARCH_INTEL_SOCFPGA and dropping the other ARCH* arm64 Kconfig entries. The side effect is that the INTEL_STRATIX10_SERVICE will now be available for both 32-bit and 64-bit Intel SoCFPGA, even though it is used only for 64-bit.

firmware: smccc: Add HAVE_ARM_SMCCC_DISCOVERY to identify SMCCC v1.1 and above
SMCCC v1.0 lacked discoverability of version and features. To accelerate adoption of few mitigations and protect systems more rapidly from various vulnerability, PSCI v1.0 was updated to add SMCCC discovery mechanism though the PSCI firmware implementation of PSCI_FEATURES(SMCCC_VERSION) which returns success on firmware compliant to SMCCC v1.1 and above. This inturn makes SMCCC v1.1 and above dependent on ARM_PSCI_FW for backward compatibility. Let us introduce a new hidden config for the same to build more features on top of SMCCC v1.1 and above. While at it, also sort alphabetically the psci entry.

USB: pci-quirks: Add Raspberry Pi 4 quirk
On the Raspberry Pi 4, after a PCI reset, VL805's firmware may either be loaded directly from an EEPROM or, if not present, by the SoC's VideoCore. Inform VideoCore that VL805 was just reset. Also, as this creates a dependency between USB_PCI and VideoCore's firmware interface, and since USB_PCI can't be set as a module neither this can. Reflect that on the firmware interface Kconfg.

firmware: qcom_scm: Dynamically support SMCCC and legacy conventions
Dynamically support SMCCCC and legacy conventions by detecting which convention to use at runtime. qcom_scm_call_atomic and qcom_scm_call can then be moved in qcom_scm.c and use underlying convention backend as appropriate. Thus, rename qcom_scm-64,-32 to reflect that they are backends for -smc and -legacy, respectively. Also add support for making SCM calls earlier than when SCM driver probes to support use cases such as qcom_scm_set_cold_boot_addr. Support is added by lazily initializing the convention and guarding the query with a spin lock. The limitation of these early SCM calls is that they cannot use DMA, as in the case of >4 arguments for SMC convention and any non-atomic call for legacy convention.

Char/Misc driver patches for 5.4-rc1
Here is the big char/misc driver pull request for 5.4-rc1.
As has been happening in previous releases, more and more individual
driver subsystem trees are ending up in here. Now if that is good or
bad I can't tell, but hopefully it makes your life easier as it's more
of an aggregation of trees together to one merge point for you.
Anyway, lots of stuff in here:
- habanalabs driver updates
- thunderbolt driver updates
- misc driver updates
- coresight and intel_th hwtracing driver updates
- fpga driver updates
- extcon driver updates
- some dma driver updates
- char driver updates
- android binder driver updates
- nvmem driver updates
- phy driver updates
- parport driver fixes
- pcmcia driver fix
- uio driver updates
- w1 driver updates
- configfs fixes
- other assorted driver updates
All of these have been in linux-next for a long time with no reported
issues.

ARM: SoC driver updates for v5.4
The branch contains driver changes that are tightly
connected to SoC specific code. Aside from smaller
cleanups and bug fixes, here is a list of the notable
changes.
New device drivers:
- The Turris Mox router has a new "moxtet" bus driver
for its on-board pluggable extension bus. The
same platform also gains a firmware driver.
- The Samsung Exynos family gains a new Chipid driver
exporting using the soc device sysfs interface
- A similar socinfo driver for Qualcomm Snapdragon
chips.
- A firmware driver for the NXP i.MX DSP IPC protocol
using shared memory and a mailbox
Other changes:
- The i.MX reset controller driver now supports the
NXP i.MX8MM chip
- Amlogic SoC specific drivers gain support for
the S905X3 and A311D chips
- A rework of the TI Davinci framebuffer driver to
allow important cleanups in the platform code
- A couple of device drivers for removed ARM SoC
platforms are removed. Most of the removals were
picked up by other maintainers, this contains
whatever was left.
