[PATCH RFT 00/20] Venus cleanups

[PATCH RFT 00/20] Venus cleanups

[Konrad Dybcio]

With the driver supporting multiple generations of hardware, some mold
has definitely grown over the code..

This series attempts to amend this situation a bit by commonizing some
code paths and fixing some bugs while at it.

Only tested on SM8250.

Definitely needs testing on:

- SDM845 with old bindings
- SDM845 with new bindings or 7180
- MSM8916
- MSM8996

[PATCH RFT 01/20] media: venus: pm_helpers: Only set rate of the core clock in core_clks_enable

[Konrad Dybcio]

Commit c22b1a29497c ("media: venus: core,pm: Vote for min clk freq
during venus boot") intended to up the rate of the Venus core clock
from the XO minimum to something more reasonable, based on the per-
SoC frequency table.

Unfortunately, it ended up calling set_rate with that same argument
on all clocks in res->clks. Fix that using the OPP API.

"core" is used in multiple contexts when talking about Venus, rename
the function to save on confusion.

[PATCH RFT 04/20] media: venus: core: Set OPP clkname in a common code path

[Konrad Dybcio]

Calling devm_pm_opp_set_clkname() is repeated for all HFI versions in
pm_ops->core_power.

Move it to the common codepath.

This also lets us get rid of core_get_v1.

A situation like:

	...1...

bar:

is totally identical to:

[PATCH RFT 07/20] media: venus: pm_helpers: Use reset_bulk API

[Konrad Dybcio]

All of the resets are toggled together. Use the bulk api to save on some
code complexity.

Note, this change is not exactly a NOP. Instead of waiting 150-250us
between each reset toggle, the behavior now is to assert all the resets,
wait 150-250us and deassert all the resets. This should be fine, but the
logic here is really abusive, as such assertion requirements should be
expressed per-reset_control, in the provider driver.

Nothing inside the resource struct needs to be mutable. Sprinkle
'const' all over it. A lot of 'const'.

[PATCH RFT 11/20] media: venus: core: Drop cache properties in resource struct

[Konrad Dybcio]

Currently VMEM/OCMEM/LLCC is disabled on all platforms.

Make it unconditional to save on space.

These caches will not be enabled until the Venus driver can reference
them as chunks of SRAM (they're modelled as separate devices) to avoid
hardcoding magic addresses and rougely accessing the hardware,
bypassing the normal accessors.

[PATCH RFT 17/20] media: venus: pm_helpers: Simplify vcodec clock handling

[Konrad Dybcio]

Currently the infrastructure is set up for vast expandability, but
it's far too complex for what is just 0-2 clocks. Categorize the
clocks and simplify their getting.

One notable change is that vcodec clocks are switched to use
devm_clk_get_optional, which will let us commonize the code further
while leaving the burden of figuring out which SoCs need codec-specific
clocks and which don't to the bindings checker.

[PATCH RFT 18/20] media: venus: pm_helpers: Commonize getting clocks and GenPDs

[Konrad Dybcio]

As has been the story with the past few commits, much of the resource
acquisition logic is totally identical between different generations
and there's no good reason to invent a new function for each one.

Commonize core_get() and rename it to venus_get_resources() to be more
meaningful.
