0a078e0d8e media: videodev2.h: Move HI240 format to vendor-specific section
V4L2_PIX_FMT_HI240 is a 8-bit dithered RGB format specific to BTTV. Move
it from the packed YUV formats section where it was misplaced to the
vendor-specific formats section.

12fc4dad94 Revert "ACPI / resources: Use AE_CTRL_TERMINATE to terminate resources walks"
This reverts commit 8a66790b78.

Switching this function to AE_CTRL_TERMINATE broke the documented
behaviour of acpi_dev_get_resources() - AE_CTRL_TERMINATE does not, in
fact, terminate the resource walk because acpi_walk_resource_buffer()
ignores it (specifically converting it to AE_OK), referring to that
value as "an OK termination by the user function". This means that
acpi_dev_get_resources() does not abort processing when the preproc
function returns a negative value.

The V4L2_PIX_FMT_BGRA444 format has a comment that explains why its 4CC
value is GA12. This explains the development history and isn't of much
interest to readers, it should have been part of a commit message
instead. Drop the comment, anyone interested in history can turn to git.

2ef33ee7f4 ACPI: scan: Add PNP0D80 to the _DEP exceptions list
The PNP0D80 ("Windows-compatible System Power Management Controller")
device ID is used for identifying the special device object providing
the LPI (Low-power S0 Idle) _DSM interface [1].  That device object
does not supply any operation regions, but it appears in _DEP lists
for other devices in the ACPI tables on some systems to enforce
specific enumeration ordering that does not matter for Linux.

For this reason, _DEP list entries pointing to the device object whose
_CID returns PNP0D80 need not be taken into account as real operation
region dependencies, so add that device ID to the list of device IDs
for which the matching _DEP list entries should be ignored.

Accordingly, update the function used for matching device IDs in that
list to allow it to check _CID as well as _HID and rename it to
acpi_info_matches_ids().

b93b7ef617 PM: ACPI: Refresh wakeup device power configuration every time
When wakeup signaling is enabled for a bridge for the second (or every
next) time in a row, its existing device wakeup power configuration
may not match the new conditions.  For example, some devices below
it may have been put into low-power states and that changes the
device wakeup power conditions or similar.  This causes functional
problems to appear on some systems (for example,  because of it the
Thunderbolt port on Dell Precision 5550 cannot detect devices plugged
in after it has been suspended).

For this reason, modify __acpi_device_wakeup_enable() to refresh the
device wakeup power configuration of the target device on every
invocation, not just when it is called for that device first time
in a row.

7482c5cb90 PM: ACPI: PCI: Drop acpi_pm_set_bridge_wakeup()
The idea behind acpi_pm_set_bridge_wakeup() was to allow bridges to
be reference counted for wakeup enabling, because they may be enabled
to signal wakeup on behalf of their subordinate devices and that
may happen for multiple times in a row, whereas for the other devices
it only makes sense to enable wakeup signaling once.

However, this becomes problematic if the bridge itself is suspended,
because it is treated as a "regular" device in that case and the
reference counting doesn't work.

For instance, suppose that there are two devices below a bridge and
they both can signal wakeup.  Every time one of them is suspended,
wakeup signaling is enabled for the bridge, so when they both have
been suspended, the bridge's wakeup reference counter value is 2.

Say that the bridge is suspended subsequently and acpi_pci_wakeup()
is called for it.  Because the bridge can signal wakeup, that
function will invoke acpi_pm_set_device_wakeup() to configure it
and __acpi_pm_set_device_wakeup() will be called with the last
argument equal to 1.  This causes __acpi_device_wakeup_enable()
invoked by it to omit the reference counting, because the reference
counter of the target device (the bridge) is 2 at that time.

Now say that the bridge resumes and one of the device below it
resumes too, so the bridge's reference counter becomes 0 and
wakeup signaling is disabled for it, but there is still the other
suspended device which may need the bridge to signal wakeup on its
behalf and that is not going to work.

To address this scenario, use wakeup enable reference counting for
all devices, not just for bridges, so drop the last argument from
__acpi_device_wakeup_enable() and __acpi_pm_set_device_wakeup(),
which causes acpi_pm_set_device_wakeup() and
acpi_pm_set_bridge_wakeup() to become identical, so drop the latter
and use the former instead of it everywhere.

ffad560394 mtd: phram: Allow the user to set the erase page size.
Permit the user to specify the erase page size as a parameter.
This solves two problems:

- phram can access images made by mkfs.jffs2.  mkfs.jffs2 won't
create images with erase sizes less than 8KiB; many architectures
define PAGE_SIZE as 4KiB.

- Allows more effective use of small capacity devices.  JFFS2
needs somewhere between 2 and 5 empty pages for garbage collection;
and for an NVRAM part with only 32KiB of space, a smaller erase page
allows much better utilization in applications where garbage collection
is important.

"sparse warnings: (new ones prefixed by >>)"
>> drivers/mtd/maps/physmap-bt1-rom.c:78:18: sparse: sparse: cast removes address space '__iomem' of expression

Indeed we perform the __iomem-less type casting but to an integer
variable. The integer variable isn't dereferenced then, so the casting is
safe and won't cause any problem. But in order to make sparse happy and
keep the code coherent let's fix the warning by converting the local
"shift" and "chunk" variables to the "unsigned int" type (since their
value won't ever exceed three) and cast the __iomem-pointers to uintptr_t.
Add the same fix to the bt1_rom_map_read() method for unification.

639a82434f mtd: parser: cmdline: Fix parsing of part-names with colons
Some devices (especially QCA ones) are already using hardcoded partition
names with colons in it. The OpenMesh A62 for example provides following
mtd relevant information via cmdline:

  root=31:11 mtdparts=spi0.0:256k(0:SBL1),128k(0:MIBIB),384k(0:QSEE),64k(0:CDT),64k(0:DDRPARAMS),64k(0:APPSBLENV),512k(0:APPSBL),64k(0:ART),64k(custom),64k(0:KEYS),0x002b0000(kernel),0x00c80000(rootfs),15552k(inactive) rootfsname=rootfs rootwait

The change to split only on the last colon between mtd-id and partitions
will cause newpart to see following string for the first partition:

  KEYS),0x002b0000(kernel),0x00c80000(rootfs),15552k(inactive)

Such a partition list cannot be parsed and thus the device fails to boot.

Avoid this behavior by making sure that the start of the first part-name
("(") will also be the last byte the mtd-id split algorithm is using for
its colon search.

Currently direct_mapping always use the smallest pgsize which is SZ_4K
normally to mapping. This is unnecessary. we could gather the size, and
call iommu_map then, iommu_map could decide how to map better with the
just right pgsize.

>From the original comment, we should take care overlap, otherwise,
iommu_map may return -EEXIST. In this overlap case, we should map the
previous region before overlap firstly. then map the left part.

Each a iommu device will call this direct_mapping when its iommu
initialize, This patch is effective to improve the boot/initialization
time especially while it only needs level 1 mapping.

2c9cfbadfa macintosh/adb-iop: Always wait for reply message from IOP
A recent patch incorrectly altered the adb-iop state machine behaviour
and introduced a regression that can appear intermittently as a
malfunctioning ADB input device. This seems to be caused when reply
packets from different ADB commands become mixed up, especially during
the adb bus scan. Fix this by unconditionally entering the awaiting_reply
state after sending an explicit command, even when the ADB command won't
generate a reply from the ADB device.

It turns out that the IOP always generates reply messages, even when the
ADB command does not produce a reply packet (e.g. ADB Listen command).
So it's not really the ADB reply packets that are being mixed up, it's the
IOP messages that enclose them. The bug goes like this:

  1. CPU sends a message to the IOP, expecting no response because this
     message contains an ADB Listen command. The ADB command is now
     considered complete.

  2. CPU sends a second message to the IOP, this time expecting a
     response because this message contains an ADB Talk command. This
     ADB command needs a reply before it can be completed.

  3. adb-iop driver receives an IOP message and assumes that it relates
     to the Talk command. It's actually an empty one (with flags ==
     ADB_IOP_EXPLICIT|ADB_IOP_TIMEOUT) for the previous command. The
     Talk command is now considered complete but it gets the wrong reply
     data.

  4. adb-iop driver gets another IOP response message, which contains
     the actual reply data for the Talk command, but this is dropped
     (the driver is no longer in awaiting_reply state).

61f54de2e9 net: hns3: remove a misused pragma packed
hclge_dbg_reg_info[] is defined as an array of packed structure
accidentally. However, this array contains pointers, which are
no longer aligned naturally, and cannot be relocated on PPC64.
Hence, when compile-testing this driver on PPC64 with
CONFIG_RELOCATABLE=y (e.g. PowerPC allyesconfig), there will be
some warnings.

Since each field in structure hclge_qos_pri_map_cmd and
hclge_dbg_bitmap_cmd is type u8, the pragma packed is unnecessary
for these two structures as well, so remove the pragma packed in
hclge_debugfs.h to fix this issue, and this increases
hclge_dbg_reg_info[] by 4 bytes per entry.

93549516d4 cpufreq: tegra194: Remove unnecessary frequency calculation
The Tegra194 CPUFREQ driver sets the CPUFREQ_NEED_INITIAL_FREQ_CHECK
flag which means that the CPUFREQ framework will call the 'get' callback
on boot to determine the current frequency of the CPUs. Therefore, it is
not necessary for the Tegra194 CPUFREQ driver to internally call the
tegra194_get_speed_common() during initialisation to query the current
frequency as well. Fix this by removing the call to the
tegra194_get_speed_common() during initialisation and simplify the code.

cfef4bcacc cpufreq: tegra186: Simplify cluster information lookup
The CPUFREQ driver framework references each individual CPUs when
getting and setting the speed. Tegra186 has 3 clusters of A57 CPUs and
1 cluster of Denver CPUs. Hence, the Tegra186 CPUFREQ driver need to
know which cluster a given CPU belongs to. The logic in the Tegra186
driver can be greatly simplified by storing the cluster ID associated
with each CPU in the tegra186_cpufreq_cpu structure. This allow us to
completely remove the Tegra cluster info structure from the driver and
simplifiy the code.

b7b4e78552 cpufreq: tegra186: Fix sparse 'incorrect type in assignment' warning
Sparse warns that the incorrect type is being assigned to the CPUFREQ
driver_data variable in the Tegra186 CPUFREQ driver. The Tegra186
CPUFREQ driver is assigned a type of 'void __iomem *' to a pointer of
type 'void *' ...

The Tegra186 CPUFREQ driver is using the policy->driver_data variable to
store and iomem pointer to a Tegra186 CPU register that is used to set
the clock speed for the CPU. This is not necessary because the register
base address is already stored in the driver data and the offset of the
register for each CPU is static. Therefore, fix this by adding a new
structure with the register offsets for each CPU and store this in the
main driver data structure along with the register base address. Please
note that a new structure has been added for storing the register
offsets rather than a simple array, because this will permit further
clean-ups and simplification of the driver.
