      Since WM8650 has the same 'WMT' SDHC controller as WM8505, and the driver
is already in the kernel, this node enables the controller support for
WM8650

      ARM: Fix broken USB support in multi_v7_defconfig for sunxi devices · 5b1a6181
      由 Timo Sigurdsson 提交于 
      Commit 69fb4dca ("power: Add an axp20x-usb-power driver") introduced a
new driver for the USB power supply used on various Allwinner based SBCs.
However, the driver was not added to multi_v7_defconfig which breaks USB
support for some boards (e.g. LeMaker BananaPi) as the kernel will now
turn off the USB power supply during boot by default if the driver isn't
present. (This was not the case in linux 4.3 or lower where the USB power
was always left on.)

Hence, add the driver to multi_v7_defconfig in order to keep USB support
working on those boards that require it.

      ARM: versatile: fix MMC/SD interrupt assignment · 20f12758
      由 Linus Walleij 提交于 
      Commit 0976c946
"arm/versatile: Fix versatile irq specifications"
has an off-by-one error on the Versatile AB that has
been regressing the Versatile AB hardware for some time.

However it seems like the interrupt assignments have
never been correct and I have now adjusted them according
to the specification. The masks for the valid interrupts
made it impossible to assign the right SIC interrupt
for the MMCI, so I went in and fixed these to correspond
to the specifications, and added references if anyone
wants to double-check.

Due to the Versatile PB including the Versatile AB
as a base DTS file, we need to override and correct
some values to correspond to the actual changes in the
hardware.

For the Versatile PB I don't think the IRQ line
assignment for MMCI has ever been correct for either of
the two MMCI blocks. It would be nice if someone with the
physical PB board could test this.

Patch tested on the Versatile AB, QEMU for Versatile AB
and QEMU for Versatile PB.

      ARM: nomadik: set latencies to 8 cycles · a461a3ec
      由 Linus Walleij 提交于 
      The Nomadik has sporadic crashes because of these latencies, setting
them to max makes the platform work nicely, so use this values for
now.

These latencies were set to 2 since the Nomadik platform was merged,
but I suspect they never took effect until the right size and
associativity for the cache was specified in the device tree and
that is why the crash comes now.

      ARM: OMAP2+: am43xx: enable GENERIC_CLOCKEVENTS_BROADCAST · 0b3e6fca
      由 Grygorii Strashko 提交于 
      System will misbehave in the following case:
- AM43XX only build (UP);
- CONFIG_CPU_IDLE=y
- ARM TWD timer enabled and selected as clockevent device.

In the above case, It's expected that broadcast timer will be used as
backup timer when CPUIdle will put MPU in low power states where ARM
TWD will stop and lose its context. But, the CONFIG_SMP might not be
selected when kernel is built for AM43XX SoC only and, as result,
GENERIC_CLOCKEVENTS_BROADCAST option will not be selected also. This
will break CPUIdle and System will stuck in low power states.

Hence, fix it by selecting GENERIC_CLOCKEVENTS_BROADCAST option for
AM43XX SoCs always and add empty tick_broadcast() function
implementation - no need to send any IPI on UP. After this change
timer1 will be selected as broadcast timer the same way as for SMP,
and CPUIdle will work properly.

Analysis is as follows:
I put some instrumental code and get the
following .h files inclusion sequence:

                 from ./arch/arm64/include/asm/stat.h:23,

include/linux/sched.h:113:1: error: expected ‘=’, ‘,’, ‘;’, ‘asm’ or ‘__attribute__’ before ‘struct’

 ^

CONFIG_COMPAT=y is enabled while 39 and 48 bit VA is selected.
When 42 bit VA is selected, it does not enable CONFIG_COMPAT=y

In ./arch/arm64/include/asm/stat.h:23, it has
"#ifdef CONFIG_COMPAT"
"#include <asm/compat.h>"
"..."
"#endif"

Since ./arch/arm64/include/asm/stat.h does not
include ./arch/arm64/include/asm/compat.h,
then it will not include include/linux/sched.h
Hence we have to manually add "#include <linux/sched.h>"
in drivers/memory/fsl_ifc.c

      ARM: dts: vf610: fix clock definition for SAI2 · 531ee1f4
      由 Stefan Agner 提交于 
      So far, only the bus clock has been assigned, but in reality the
SAI IP has for clock inputs. The driver has been updated to
make use of the additional clock inputs by c3ecef21 ("ASoC:
fsl_sai: add sai master mode support"). Due to a bug in the
clock tree, the audio clock has been enabled none the less by
the specified bus clock (see "ARM: imx: clk-vf610: fix SAI
clock tree"), which made master mode even without the proper
clock assigned working.

This patch completes the clock definition for SAI2. On Vybrid,
only two MCLK out of the four options are available (the first
being the bus clock itself). See chapter 8.10.1.2.3 of the
Vybrid Reference manual ("SAI transmitter and receiver options
for MCLK selection"). Note: The audio clocks are only required
in master mode.

      ARM: imx: clk-vf610: fix SAI clock tree · 3b60a26f
      由 Stefan Agner 提交于 
      The Synchronous Audio Interface (SAI) instances are clocked by
independent clocks: The bus clock and the audio clock (as shown in
Figure 51-1 in the Vybrid Reference Manual). The clock gates in
CCGR0/CCGR1 for SAI0 through SAI3 are bus clock gates, as access
tests to the registers with/without gating those clocks have shown.
The audio clock is gated by the SAIx_EN gates in CCM_CSCDR1,
followed by a clock divider (SAIx_DIV). Currently, the parent of
the bus clock gates has been assigned to SAIx_DIV, which is not
involved in the bus clock path for the SAI instances (see chapter
9.10.12, SAI clocking in the Vybrid Reference Manual).

Fix this by define the parent clock of VF610_CLK_SAIx to be the bus
clock.

If the driver needs the audio clock (when used in master mode), a
fixed device tree is required which assign the audio clock properly
to VF610_CLK_SAIx_DIV.

      ARM: ixp4xx: fix read{b,w,l} return types · d66e5139
      由 Arnd Bergmann 提交于 
      On ixp4xx, the readl() function returns an 'unsigned long' output
when indirect I/O is used. This is unlike any other platform, and
it causes lots of harmless compiler warnings, such as:

drivers/ata/libahci.c: In function 'ahci_show_host_version':
drivers/ata/libahci.c:254:22: warning: format '%x' expects argument of type 'unsigned int', but argument 3 has type 'long unsigned int' [-Wformat=]
drivers/block/mtip32xx/mtip32xx.c: In function 'mtip_hw_read_registers':
drivers/block/mtip32xx/mtip32xx.c:2602:31: warning: format '%X' expects argument of type 'unsigned int', but argument 3 has type 'long unsigned int' [-Wformat=]

drivers/block/cciss.c:3845:25: warning: format '%d' expects argument of type 'int', but argument 4 has type 'long unsigned int' [-Wformat=]

This changes all six of the ixp4xx specific I/O read functions
to return the same types that we have in the normal asm/io.h,
to avoid the warnings.

      This patch is specifically for PCI support on the Versatile PB board using

this issue, this patch replaces the current dynamic mechanism with a
static value as is done in the non-DT case.
