fc244e3af2 Removal of the deprectated num-slots property from all Rockchip dw-mmc
nodes. The rv1108 gains support for sd-cards on the evaluation board and
 the general nodes get a bit of cosmetic. On rk3288 the evb gains support
 saradc and the adc-key connected to it while some more boards also get
 their mali gpu enabled (fennec, evb, tinker).
 
 The biggest set of changes can be found on the rk3228/rk3229 combo this
 time. It gets core support for efuse, sdmmc, sdio, io-domans and spdif
 as well as a separate rk3229.dtsi that will keep the slight differences
 between the two brothers rk3228/rk3229. The evaluation board also gets
 some attention and abled nodes (regulators, io-domains, emmc, tsadc keys)
 
 But I think the most interesting change is the cpu enable-method for it.
 Instead of using the older in-kernel method, we're now also moving to
 handling this in firmware via the psci interface on 32bit Rockchip socs.
 In a recently merged pull request [0] support for the rk3228/rk3229 was
 added to OP-TEE including the psci support and it seems supporting other
 32bit Rockchip socs that way is also planned for the future.

f7ec9146eb Renesas ARM Based SoC DT Updates for v4.14
Changes of note:
 
 * Add pin controller support to the RZ/G1M (r8a7743) SoC and
   RZ/A1 (r7s72100) SoCs now that the driver is available in v4.13-rc1.
 
 * Add GPIO support to the RZ/G1M (r8a7743) SoC now that the driver
   is availabe in v4.13-rc1.
 
 * Enable MMCIF0 and Ethernet AVB support on the RZ/G1M (r8a7743) SoC and
   the iWave-RZG1M-20M Qseven SOM. This depends on newly added pin
   controller support noted above.
 
 * Use R-Car Gen 2 fallback binding for vin nodes
 
   This makes binding use consistent across R-Car Gen 2 SoCs.
   It does not have any run-time effect
 
 * Use SMP jump stub SRAM region from DT on R-Car Gen 2 SoCs
 
   Geert Uytterhoeven says, "The R-Car Gen2 platform code for CPU core
   bringup needs to copy a jump stub to on-SoC SRAM.  Currently it uses a
   hardcoded address pointing to ICRAM1."
 
 * Add Inter Connect RAM to R-Car Gen 2 and RZ/G1 SoCs
 
   Geert Uytterhoeven says, "R-Car Gen2 and RZ/G1 SoCs contain two or three
   blocks of SRAM, which can be used for several purposes.  One such purpose
   is holding a jump stub for CPU core bringup."
 * Use generic compatible string for I2C EEPROM for RZ/A1 (r7s72100) SoC
   and koelsch board.
 
   This is part of a tree-wide cleanup by Javier Martinez Canillas

65f4740e72 ARM: SoC fixes for 4.13
This comes a bit later than I planned, and as a consequence is a larger
 than it should be.
 
 Most of the changes are devicetree fixes, across lots of platforms:
 Renesas, Samsung Exynos, Marvell EBU, TI OMAP, Rockchips, Amlogic Meson,
 Sigma Desings Tango, Allwinner SUNxi and TI Davinci.
 
 Also across many platforms, I applied an older series of simple randconfig
 build fixes. This includes making the CONFIG_MTD_XIP option compile again,
 which had been broken for many years and probably has not been missed, but
 it felt wrong to just remove it completely.
 
 The only other changes are:
 
  - We enable HWSPINLOCK in defconfig to get some Qualcomm boards
    to work out of the box.
 
  - A few regression fixes for Texas Instruments OMAP2+.
 
  - A boot regression fix for the Renesas regulator quirk.
 
  - A suspend/resume fix for Uniphier SoCs, fixing the resume of the
    system bus.

Two fixes to correct the EMAC blocks memory region size to match the
 datasheet. One that converts raw A83T clock indices to macros from the
 clk dt-binding header, completing the A83T sunxi-ng clk driver.

264e22afa3 Third Round of Renesas ARM Based SoC Fixes for v4.13
Fix deadlock in regulator quirk for R-Car Gen 2 SoCs
 
 The da9063/da9210 regulator quirk for R-Car Gen2 boards uses a bus
 notifier, and unregisters the notifier when it is no longer needed.
 However, a notifier must not be unregistered from within the call chain.
 
 This bug went unnoticed, as blocking_notifier_chain_unregister() didn't
 take the semaphore during early boot. This is no longer the case as of
 upstream commit 1c3c5eab17 ("sched/core: Enable might_sleep() and
 smp_processor_id() checks early") and a deadlock occurs.

fce8dc5e50 ARM: shmobile: rcar-gen2: Fix deadlock in regulator quirk
Simon Horman reported that Koelsch and Lager hang during boot, and
bisected this to commit 1c3c5eab17 ("sched/core: Enable
might_sleep() and smp_processor_id() checks early").

The da9063/da9210 regulator quirk for R-Car Gen2 boards uses a bus
notifier, and unregisters the notifier when it is no longer needed.
However, a notifier must not be unregistered from within the call chain.

This bug went unnoticed, as blocking_notifier_chain_unregister() didn't
take the semaphore during early boot.  The aforementioned commit changed
that behavior, leading to a deadlock.

Fix this by removing the call to bus_unregister_notifier(), and keeping
local completion state instead.

1d20d8a9fc ARM: pxa: select both FB and FB_W100 for eseries
We get a link error trying to access the w100fb_gpio_read/write
functions from the platform when the driver is a loadable module
or not built-in, so the platform already uses 'select' to hard-enable
the driver.

However, that fails if the framebuffer subsystem is disabled
altogether.

I've considered various ways to fix this properly, but they
all seem like too much work or too risky, so this simply
adds another 'select' to force the subsystem on as well.

c1ae3f7c4b ARM: sirf: mark sirfsoc_init_late as __maybe_unused
sirfsoc_init_late is called by each of the three individual
SoC definitions, but in a randconfig build, we can encounter
a situation where they are all disabled:

arch/arm/mach-prima2/common.c:18:123: warning: 'sirfsoc_init_late' defined but not used [-Wunused-function]

While that is not a useful configuration, the warning also
doesn't help, so this patch marks the function as __maybe_unused
to let the compiler know it is there intentionally.

1f3b4d8fcc ARM: ixp4xx: use normal prototype for {read,write}s{b,w,l}
ixp4xx defines the arguments to its __indirect_writesb() and other
functions as pointers to fixed-size data. This is not necessarily
wrong, and it works most of the time, but it causes warnings in
at least one driver:

drivers/net/ethernet/smsc/smc91x.c: In function 'smc_rcv':
drivers/net/ethernet/smsc/smc91x.c:495:21: error: passing argument 2 of '__indirect_readsw' from incompatible pointer type [-Werror=incompatible-pointer-types]
   SMC_PULL_DATA(lp, data, packet_len - 4);

All other definitions of the same functions pass void pointers,
so doing the same here avoids the warnings.

595a9f9a57 ARM: omap1/ams-delta: warn about failed regulator enable
The modem pm handler in the ams-delta board uses regulator_enable()
but does not check for a successful return code:

board-ams-delta.c:521:3: error: ignoring return value of 'regulator_enable', declared with attribute warn_unused_result [-Werror=unused-result]

It is not easy to propagate that return code to the callers in
uart_configure_port/uart_suspend_port/uart_resume_port, unless
we change all UART drivers, and it is unclear what those would
do with the return code.

Instead, this patch uses a runtime warning to replace the
compiletime warning. I have checked that the regulator in question
is hardcoded to a fixed-voltage GPIO regulator, and that should
never fail to get enabled if I understand the code right.

47589c4af9 ARM: rpc: rename RAM_SIZE macro
The RAM_SIZE macro in mach/hardware.h conflicts with macros of
the same name in multiple drivers, leading to annoying build warnings:

 #define RAM_SIZE  0x10000000

We don't use RAM_SIZE/RAM_START at all, so we could just remove
them, but it might be nice to leave them for documentation purposes,
so this renames them to RPC_RAM_SIZE/RPC_RAM_START in order to
avoid the build warnings

bd7fefe1f0 ARM: w90x900: normalize clk API
w90x900 still provides its own variant of the clk API rather than using
the generic COMMON_CLK API. This generally works, but it causes some link
errors with drivers using the clk_set_rate, clk_get_parent, clk_set_parent
or clk_round_rate functions when a platform lacks those interfaces.

This adds empty stub implementations for each of them, and I don't even
try to do something useful here but instead just print a WARN() message
to make it obvious what is going on if they ever end up being called.

The drivers that call these won't be used on these platforms (otherwise
we'd get a link error today), so the added code is harmless bloat and
will warn about accidental use.

A while ago there was a proposal to change w90x900 to use the common-clk
implementation, which would be the way it should be handled properly.
