ASoC: soc-dai: add snd_soc_pcm_dai_prepare()
We have 2 type of component functions
snd_soc_dai_xxx()     is focusing to dai itself,
snd_soc_pcm_dai_xxx() is focusing to rtd related dai.

Now we can update snd_soc_dai_prepare() to
snd_soc_pcm_dai_prepare(). This patch do it.

ASoC: soc-dai: don't overwide dai->driver->ops
Current ASoC overwrites null_dai_ops to dai->driver->ops if it
was NULL. But, we can remove it if framework always checks
dai->driver->ops when it uses DAI callbacks.
This patch do it, and removes null_dai_ops.

8d0910121b gpio: Make "offset" and "unsigned int", not just "unsigned"
When I copied the function prototypes from the GPIO header file into
my own driver, checkpatch yelled at me saying that I shouldn't use use
"unsigned" but instead should say "unsigned int".  Let's make the
header file use "unsigned int" so others who copy like I did won't get
yelled at.

Taking a clock and returning a pid_type is a more general and
a superset of taking a timer and returning a pid_type.

Perform this generalization so that future changes may use

9dd124b63a iommu: spapr_tce: Disable compile testing to fix build on book3s_32 config
Although SPAPR_TCE_IOMMU itself can be compile tested on certain PowerPC
configurations, its presence makes arch/powerpc/kvm/Makefile to select
modules which do not build in such configuration.

The arch/powerpc/kvm/ modules use kvm_arch.spapr_tce_tables which exists
only with CONFIG_PPC_BOOK3S_64.  However these modules are selected when
COMPILE_TEST and SPAPR_TCE_IOMMU are chosen leading to build failures:

d1dcb7255c iommu/mediatek: Fix MTK_IOMMU dependencies

    drivers/iommu/dma-iommu.o: In function `iommu_dma_mmap':
    dma-iommu.c:(.text+0x836): undefined reference to `dma_pgprot'

IOMMU_DMA must not be selected, unless HAS_DMA=y.

Hence fix this by making MTK_IOMMU depend on HAS_DMA.
While at it, remove the dependency on ARM || ARM64, as that is already
implied by the dependency on ARCH_MEDIATEK.

933db73351 drm/qxl: qxl_release use after free
qxl_release should not be accesses after qxl_push_*_ring_release() calls:
userspace driver can process submitted command quickly, move qxl_release
into release_ring, generate interrupt and trigger garbage collector.

It can lead to crashes in qxl driver or trigger memory corruption
in some kmalloc-192 slab object

Gerd Hoffmann proposes to swap the qxl_release_fence_buffer_objects() +
qxl_push_{cursor,command}_ring_release() calls to close that race window.

bcf41dc480 gpio: pca953x: fix handling of automatic address incrementing
Some of the chips supported by the pca953x driver need the most
significant bit in the address word set to automatically increment the
address pointer on subsequent reads and writes (example: PCA9505). With
this bit unset the same register is read multiple times on a multi-byte
read sequence. Other chips must not have this bit set and autoincrement
always (example: PCA9555).

Up to now this AI bit was interpreted to be part of the address, which
resulted in inconsistent regmap caching when a register was written with
AI set and then read without it. This happened for the PCA9505 in
pca953x_gpio_set_multiple() where pca953x_read_regs() bulk read from the
cache for registers 0x8-0xc and then wrote to registers 0x88-0x8c. (Side
note: reading 5 values from offset 0x8 yiels OP0 5 times because AI must
be set to get OP0-OP4, which is another bug that is resolved here as a
by-product.) The same problem happens when calls to gpio_set_value() and
gpio_set_array_value() were mixed.

With this patch the AI bit is always set for chips that support it. This
works as there are no code locations that make use of the behaviour with
AI unset (for the chips that support it).

Note that the call to pca953x_setup_gpio() had to be done a bit earlier
to make the NBANK macro work.

The history of this bug is a bit complicated. Commit b32cecb46b
("gpio: pca953x: Extract the register address mangling to single
function") changed which chips and functions are affected. Commit
3b00691cc4 ("gpio: pca953x: hack to fix 24 bit gpio expanders") used
some duct tape to make the driver at least appear to work. Commit
4942723276 ("gpio: pca953x: Perform basic regmap conversion")
introduced the caching. Commit b4818afeac ("gpio: pca953x: Add
set_multiple to allow multiple bits to be set in one write.") introduced
the .set_multiple() callback which didn't work for chips that need the
AI bit which was fixed later for some chips in 8958262af3 ("gpio:
pca953x: Repair multi-byte IO address increment on PCA9575"). So I'm
sorry, I don't know which commit I should pick for a Fixes: line.

The commit 96d7c7b3e6 ("gpio: gpio-pca953x, Add get_multiple function")
basically did everything wrong from style and code reuse perspective, i.e.
- it didn't utilize existing PCA953x internal helpers
- it didn't utilize bitmap API
- it misses the point that ilog2(), besides that BANK_SFT is useless,
  can be used in macros
- it has indentation issues.

Rewrite the function completely.

1d09094aa6 arm64: vdso: use consistent 'map' nomenclature
The current code doesn't use a consistent naming scheme for structures,
enums, or variables, making it harder than necessary to determine the
relationship between these.

Let's make this easier by consistently using 'map' nomenclature for
mappings created in userspace, minimizing redundant comments, and
using designated array initializers to tie indices to their respective
elements.

There should be no functional change as a result of this patch.

3ee16ff343 arm64: vdso: simplify arch_vdso_type ifdeffery
Currently we have some ifdeffery to determine the number of elements in
enum arch_vdso_type as VDSO_TYPES, rather that the usual pattern of
having the enum define this:

| enum foo_type {
|         FOO_TYPE_A,
|         FOO_TYPE_B,
| #ifdef CONFIG_C
|         FOO_TYPE_C,
| #endif
|         NR_FOO_TYPES
| }

... however, given we only use this number to size the vdso_lookup[]
array, this is redundant anyway as the compiler can automatically size
the array to fit all defined elements.

So let's remove the VDSO_TYPES to simplify the code.

At the same time, let's use designated initializers for the array
elements so that these are guarnateed to be at the expected indices,
regardless of how we modify the structure. For clariy the redundant
explicit initialization of the enum elements is dropped.

There should be no functional change as a result of this patch.

74fc72e77d arm64: vdso: remove aarch32_vdso_pages[]
The aarch32_vdso_pages[] array is unnecessarily confusing. We only ever
use the C_VECTORS and C_SIGPAGE slots, and the other slots are unused
despite having corresponding mappings (sharing pages with the AArch64
vDSO).

Let's make this clearer by using separate variables for the vectors page
and the sigreturn page. A subsequent patch will clean up the C_* naming
and conflation of pages with mappings.

Note that since both the vectors page and sig page are single
pages, and the mapping is a single page long, their pages array do not
need to be NULL-terminated (and this was not the case with the existing
code for the sig page as it was the last entry in the aarch32_vdso_pages
array).

There should be no functional change as a result of this patch.

16afd70af5 clk: meson: meson8b: Make the CCF use the glitch-free VPU mux
The "vpu_0" or "vpu_1" clock trees should not be updated while the
clock is running. Enforce this by setting CLK_SET_RATE_GATE on the
"vpu_0" and "vpu_1" gates. This makes the CCF switch to the "vpu_1"
tree when "vpu_0" is currently active and vice versa, which is exactly
what the vendor driver does when updating the frequency of the VPU
clock.

da1978ac3d clk: meson: meson8b: Fix the first parent of vid_pll_in_sel
Use hdmi_pll_lvds_out as parent of the vid_pll_in_sel clock. It's not
easy to see that the vendor kernel does the same, but it actually does.
meson_clk_pll_ops in mainline still cannot fully recalculate all rates
from the HDMI PLL registers because some register bits (at the time of
writing it's unknown which bits are used for this) double the HDMI PLL
output rate (compared to simply considering M, N and FRAC) for some (but
not all) PLL settings.

Update the vid_pll_in_sel parent so our clock calculation works for
simple clock settings like the CVBS output (where no rate doubling is
going on). The PLL ops need to be fixed later on for more complex clock
settings (all HDMI rates).

descriptors and switches the two Freescale i.MX boards over
to passing descriptors instead of global GPIO numbers.

We use the typical names "enable" and "reset" as found in
the device tree bindings for panel GPIOs.

This saves a lot of code in the driver and makes it possible
to get rid of the platform data header altogether.
