ti-sysc dts changes for v5.3

We can now drop the custom dts property "ti,hwmods" for drivers that
have the ti-sysc interconnect target module configured in dts.

Let's start with a minimal changes to omap4 uart and mmc. We use
omap4 as the starting point as it has runtime PM implemented and all
the omap variants after that are based on it with similar clkctrl
clock for the modules. More devices will be updated later on as they
get tested.

Note that these changes are based on the related ti-sysc driver
changes.

387e3746d0 locks: eliminate false positive conflicts for write lease
check_conflicting_open() is checking for existing fd's open for read or
for write before allowing to take a write lease.  The check that was
implemented using i_count and d_count is an approximation that has
several false positives.  For example, overlayfs since v4.19, takes an
extra reference on the dentry; An open with O_PATH takes a reference on
the dentry although the file cannot be read nor written.

Change the implementation to use i_readcount and i_writecount to
eliminate the false positive conflicts and allow a write lease to be
taken on an overlayfs file.

The change of behavior with existing fd's open with O_PATH is symmetric
w.r.t. current behavior of lease breakers - an open with O_PATH currently
does not break a write lease.

This increases the size of struct inode by 4 bytes on 32bit archs when
CONFIG_FILE_LOCKING is defined and CONFIG_IMA was not already
defined.

1d76898928 ASoC: soc-core: allow no Platform on dai_link
dai_link is used to selecting Component (= CPU/Codec/Platform) and
DAI (= CPU/Codec). And selected CPU/Codec/Platform components are
*listed* on Card.

Many drivers don't need special Platform component, but was
mandatory at legacy style ALSA SoC.
Thus, there is this kind of settings on many drivers.

	dai_link->platform_of_node = dai_link->cpu_of_node;

In this case, soc_bind_dai_link() will pick-up "CPU component" as
"Platform component", and try to add it to snd_soc_pcm_runtime.
But it will be ignored, because it is already added when CPU bindings.

Historically, this kind of "CPU component" is used/selected as
"Platform" on many ALSA SoC drivers.
OTOH, Dummy Platform will be selected automatically by ALSA SoC if
driver doesn't have Platform settings.

These indicates that there are 2 type of Platforms exist at current
ALSA SoC if driver doesn't need special Platform.

	1) use Dummy Platform as Platform component
	2) use CPU component  as Platform component

ALSA SoC will call Dummy Platform callback function if it is using
Dummy Platform, but it is completely pointless. Because it is the
sound card which doesn't need special Platform.

Thus, the behavior we request to ALSA SoC is selecting 2) automatically
instead of 1) if sound card doesn't need special Platform.
And, 2) means "do nothing" as above explain.

These were needed at legacy style dai_link, but is no longer needed
at modern style dai_link anymore.

This patch allows "no Platform" settings on dai_link, and will do
nothing for it if there was no platform settings. This is same as 2).

By this patch, all drivers which is selecting "CPU component" as
"Platform" can remove such settings.

1bf4e09227 drm/modes: Allow to specify rotation and reflection on the commandline
Rotations and reflections setup are needed in some scenarios to initialise
properly the initial framebuffer. Some drivers already had a bunch of
quirks to deal with this, such as either a private kernel command line
parameter (omapdss) or on the device tree (various panels).

In order to accomodate this, let's create a video mode parameter to deal
with the rotation and reflexion.

3aeeb13d89 drm/modes: Support modes names on the command line
The drm subsystem also uses the video= kernel parameter, and in the
documentation refers to the fbdev documentation for that parameter.

However, that documentation also says that instead of giving the mode using
its resolution we can also give a name. However, DRM doesn't handle that
case at the moment. Even though in most case it shouldn't make any
difference, it might be useful for analog modes, where different standards
might have the same resolution, but still have a few different parameters
that are not encoded in the modes (NTSC vs NTSC-J vs PAL-M for example).

Allow userspace to issue a netlink query against the ib_device for
something like "uverbs" and get back the char dev name, inode major/minor,
and interface ABI information for "uverbs0".

Since we are now in netlink this can also trigger a module autoload to
make the uverbs device come into existence.

Largely this will let us replace searching and reading inside sysfs to
setup devices, and provides an alternative (using driver_id) to device
name based provider binding for things like rxe.

674: (67) r1 <<= 1
675: (0f) r0 += r1

At this point the verifier will notice that scalar R1 is used in map pointer adjustment.
R1 has to be precise for later operations on R0 to be validated properly.

The verifier will backtrack the above code in the following way:
last_idx 675 first_idx 664
regs=2 stack=0 before 675: (0f) r0 += r1         // started backtracking R1 regs=2 is a bitmask
regs=2 stack=0 before 674: (67) r1 <<= 1
regs=2 stack=0 before 673: (25) if r1 > 0x1e goto pc+12
regs=2 stack=0 before 672: (57) r1 &= 255
regs=2 stack=0 before 671: (1f) r1 -= r2         // now both R1 and R2 has to be precise -> regs=6 mask
regs=6 stack=0 before 670: (bf) r1 = r8          // after this insn R8 and R2 has to be precise
regs=104 stack=0 before 669: (2f) r2 *= r1       // after this one R8, R2, and R1
regs=106 stack=0 before 668: (3f) r2 /= r1
regs=106 stack=0 before 667: (bf) r2 = r8
regs=102 stack=0 before 666: (57) r8 &= 65535
regs=102 stack=0 before 665: (bf) r8 = r7
regs=82 stack=0 before 664: (15) if r1 == 0x0 goto pc+21
 // this is the end of verifier state. The following regs will be marked precised:
 R1_rw=invP(id=0,umax_value=65535,var_off=(0x0; 0xffff)) R7_rw=invP(id=0)
parent didn't have regs=82 stack=0 marks         // so backtracking continues into parent state
last_idx 663 first_idx 655
regs=82 stack=0 before 663: (69) r1 = *(u16 *)(r0 +0)   // R1 was assigned no need to track it further
regs=80 stack=0 before 662: (15) if r0 == 0x0 goto pc+23    // keep tracking R7

 // mark R0 to be precise:
 R0_rw=invP(id=0)
parent didn't have regs=1 stack=0 marks                 // regs=1 -> tracking R0
last_idx 654 first_idx 644
regs=1 stack=0 before 654: (85) call bpf_get_hash_recalc#34 // and in the parent frame it was a return value
  // nothing further to backtrack

Two scalar registers not marked precise are equivalent from state pruning point of view.

2589726d12 bpf: introduce bounded loops
Allow the verifier to validate the loops by simulating their execution.
Exisiting programs have used '#pragma unroll' to unroll the loops
by the compiler. Instead let the verifier simulate all iterations
of the loop.
In order to do that introduce parentage chain of bpf_verifier_state and
'branches' counter for the number of branches left to explore.
See more detailed algorithm description in bpf_verifier.h

This algorithm borrows the key idea from Edward Cree approach:
https://patchwork.ozlabs.org/patch/877222/
Additional state pruning heuristics make such brute force loop walk
practical even for large loops.

90ec7a76cc iommu/io-pgtable-arm: Add support to use system cache
Few Qualcomm platforms such as, sdm845 have an additional outer
cache called as System cache, aka. Last level cache (LLC) that
allows non-coherent devices to upgrade to using caching.
This cache sits right before the DDR, and is tightly coupled
with the memory controller. The clients using this cache request
their slices from this system cache, make it active, and can then
start using it.

There is a fundamental assumption that non-coherent devices can't
access caches. This change adds an exception where they *can* use
some level of cache despite still being non-coherent overall.
The coherent devices that use cacheable memory, and CPU make use of
this system cache by default.

Looking at memory types, we have following -
a) Normal uncached :- MAIR 0x44, inner non-cacheable,
                      outer non-cacheable;
b) Normal cached :-   MAIR 0xff, inner read write-back non-transient,
                      outer read write-back non-transient;
                      attribute setting for coherenet I/O devices.
and, for non-coherent i/o devices that can allocate in system cache
another type gets added -
c) Normal sys-cached :- MAIR 0xf4, inner non-cacheable,
                        outer read write-back non-transient

Coherent I/O devices use system cache by marking the memory as
normal cached.
Non-coherent I/O devices should mark the memory as normal
sys-cached in page tables to use system cache.
