d1d3b4b4a1 ARM: dts: BCM5301X: Add interrupt properties to GPIO node
[ Upstream commit 40f7342f0587639e5ad625adaa15efdd3cffb18f ]

The GPIO controller is also an interrupt controller provider and is
currently missing the appropriate 'interrupt-controller' and
'#interrupt-cells' properties to denote that.

e18934c79f ARM: 8819/1: Remove '-p' from LDFLAGS
commit 091bb549f7722723b284f63ac665e2aedcf9dec9 upstream.

This option is not supported by lld:

    ld.lld: error: unknown argument: -p

This has been a no-op in binutils since 2004 (see commit dea514f51da1 in
that tree). Given that the lowest officially supported of binutils for
the kernel is 2.20, which was released in 2009, nobody needs this flag
around so just remove it. Commit 1a381d4a0a9a ("arm64: remove no-op -p
linker flag") did the same for arm64.

336f1090d4 ARM: 9134/1: remove duplicate memcpy() definition
commit eaf6cc7165c9c5aa3c2f9faa03a98598123d0afb upstream.

Both the decompressor code and the kasan logic try to override
the memcpy() and memmove()  definitions, which leading to a clash
in a KASAN-enabled kernel with XZ decompression:

arch/arm/boot/compressed/decompress.c:50:9: error: 'memmove' macro redefined [-Werror,-Wmacro-redefined]
 #define memmove memmove
        ^
arch/arm/include/asm/string.h:59:9: note: previous definition is here

arch/arm/include/asm/string.h:58:9: note: previous definition is here
 #define memcpy(dst, src, len) __memcpy(dst, src, len)
        ^

Here we want the set of functions from the decompressor, so undefine
the other macros before the override.

On SPEAr3xx, ethernet driver is not compatible with the SPEAr600
one.
Indeed, SPEAr3xx uses an earlier version of this IP (v3.40) and
needs some driver tuning compare to SPEAr600.

The v3.40 IP support was added to stmmac driver and this patch
fixes this issue and use the correct compatible string for
SPEAr3xx

1d50753315 ARM: 9105/1: atags_to_fdt: don't warn about stack size
commit b30d0289de72c62516df03fdad8d53f552c69839 upstream.

The merge_fdt_bootargs() function by definition consumes more than 1024
bytes of stack because it has a 1024 byte command line on the stack,
meaning that we always get a warning when building this file:

arch/arm/boot/compressed/atags_to_fdt.c: In function 'merge_fdt_bootargs':
arch/arm/boot/compressed/atags_to_fdt.c:98:1: warning: the frame size of 1032 bytes is larger than 1024 bytes [-Wframe-larger-than=]

However, as this is the decompressor and we know that it has a very shallow
call chain, and we do not actually risk overflowing the kernel stack
at runtime here.

This just shuts up the warning by disabling the warning flag for this
file.

Tested on Nexus 7 2012 builds.

a617330fc5 ARM: dts: am43x-epos-evm: Reduce i2c0 bus speed for tps65218
[ Upstream commit 20a6b3fd8e2e2c063b25fbf2ee74d86b898e5087 ]

Based on the latest timing specifications for the TPS65218 from the data
sheet, http://www.ti.com/lit/ds/symlink/tps65218.pdf, document SLDS206
from November 2014, we must change the i2c bus speed to better fit within
the minimum high SCL time required for proper i2c transfer.

When running at 400khz, measurements show that SCL spends
0.8125 uS/1.666 uS high/low which violates the requirement for minimum
high period of SCL provided in datasheet Table 7.6 which is 1 uS.
Switching to 100khz gives us 5 uS/5 uS high/low which both fall above
the minimum given values for 100 khz, 4.0 uS/4.7 uS high/low.

Without this patch occasionally a voltage set operation from the kernel
will appear to have worked but the actual voltage reflected on the PMIC
will not have updated, causing problems especially with cpufreq that may
update to a higher OPP without actually raising the voltage on DCDC2,
leading to a hang.

[ Upstream commit 77335a040178a0456d4eabc8bf17a7ca3ee4a327 ]

Fix moving mmc devices with dts aliases as discussed on the lists.
Without this we now have internal eMMC mmc1 show up as mmc2 compared
to the earlier order of devices.

a90acaf2f5 ARM: 9046/1: decompressor: Do not clear SCTLR.nTLSMD for ARMv7+ cores
[ Upstream commit 2acb909750431030b65a0a2a17fd8afcbd813a84 ]

It was observed that decompressor running on hardware implementing ARM v8.2
Load/Store Multiple Atomicity and Ordering Control (LSMAOC), say, as guest,
would stuck just after:

Uncompressing Linux... done, booting the kernel.

The reason is that it clears nTLSMD bit when disabling caches:

  nTLSMD, bit [3]

  When ARMv8.2-LSMAOC is implemented:

    No Trap Load Multiple and Store Multiple to
    Device-nGRE/Device-nGnRE/Device-nGnRnE memory.

    0b0 All memory accesses by A32 and T32 Load Multiple and Store
        Multiple at EL1 or EL0 that are marked at stage 1 as
        Device-nGRE/Device-nGnRE/Device-nGnRnE memory are trapped and
        generate a stage 1 Alignment fault.

    0b1 All memory accesses by A32 and T32 Load Multiple and Store
        Multiple at EL1 or EL0 that are marked at stage 1 as
        Device-nGRE/Device-nGnRE/Device-nGnRnE memory are not trapped.

  This bit is permitted to be cached in a TLB.

  This field resets to 1.

  Otherwise:

  Reserved, RES1

So as effect we start getting traps we are not quite ready for.

Looking into history it seems that mask used for SCTLR clear came from
the similar code for ARMv4, where bit[3] is the enable/disable bit for
the write buffer. That not applicable to ARMv7 and onwards, so retire
that bit from the masks.

a17c47fc75 ARM: dts: Configure missing thermal interrupt for 4430
[ Upstream commit 44f416879a442600b006ef7dec3a6dc98bcf59c6 ]

We have gpio_86 wired internally to the bandgap thermal shutdown
interrupt on 4430 like we have it on 4460 according to the TRM.
This can be found easily by searching for TSHUT.

For some reason the thermal shutdown interrupt was never added
for 4430, let's add it. I believe this is needed for the thermal
shutdown interrupt handler ti_bandgap_tshut_irq_handler() to call
orderly_poweroff().

[ Upstream commit 5638159f6d93b99ec9743ac7f65563fca3cf413d ]

This reverts commit c17e9377aa81664d94b4f2102559fcf2a01ec8e7.

The lpc32xx clock driver is not able to actually change the PLL rate as
this would require reparenting ARM_CLK, DDRAM_CLK, PERIPH_CLK to SYSCLK,
then stop the PLL, update the register, restart the PLL and wait for the
PLL to lock and finally reparent ARM_CLK, DDRAM_CLK, PERIPH_CLK to HCLK
PLL.

Currently, the HCLK driver simply updates the registers but this has no
real effect and all the clock rate calculation end up being wrong. This is
especially annoying for the peripheral (e.g. UARTs, I2C, SPI).

This fixes an issue where attempting atomic modeset while using
