Add an API to reset the encoder related hw blocks to ensure
a proper teardown of the pipeline. At the moment this is being
used only for the writeback encoder but eventually we can start
using this for all interfaces.

Rename dpu_hw_pipe_cdp_cfg to dpu_hw_cdp_cfg and move it
to dpu_hw_utils file so that other modules in addition to
SSPP such as writeback can use it as all the fields can
be used by writeback as well.

For vendors drivers which pass an already allocated and
initialized encoder especially for cases where the encoder
hardware is shared OR the writeback encoder shares the resources
with the rest of the display pipeline introduce a new API,
drm_writeback_connector_init_with_encoder() which expects
an initialized encoder as a parameter and only sets up the
writeback connector.

Clients of drm_writeback_connector_init() initialize the
possible_crtcs and then invoke the call to this API.
To simplify things, allow passing possible_crtcs as a parameter
to drm_writeback_connector_init() and make changes to the
other drm drivers to make them compatible with this change.
changes in v2:
- split the changes according to their functionality
changes in v3:
- allow passing possible_crtcs for existing users of
drm_writeback_connector_init()
- squash the vendor changes into the same commit so
that each patch in the series can compile individually
changes in v4:
- keep only changes related to possible_crtcs

It's typical for the bootloader to bring up the display for showing a
boot splash or efi framebuffer. But in some cases the kernel driver ends
up only partially configuring (in particular) the DPU, which might
result in e.g. that two different data paths attempts to push data to
the interface - with resulting graphical artifacts.
Naturally the end goal would be to inherit the bootloader's
configuration and provide the user with a glitch free handover from the
boot configuration to a running DPU.
But as implementing seamless transition from the bootloader
configuration to the running OS will be a considerable effort, start by
simply resetting the entire MDSS to its power-on state, to avoid the
partial configuration.

- Some DPU versions support inline rot90. It is supported only for
limited amount of UBWC formats.
- There are two versions of inline rotators, v1 (present on sm8250 and
sm7250) and v2 (sc7280). These versions differ in the list of supported
formats and in the scaler possibilities.

As per the specification of DPU_CTL_ACTIVE_CFG the configuration of
active blocks should be proactively specified, and the pingpong block is
no different.
The downstream display driver [1] confirms this by also calling
bind_pingpong_blk on CTL_ACTIVE_CFG. Note that this else-if is always
entered, as setup_intf_cfg - unlike this mainline dpu driver that
combines both behind the same function pointer - is left NULL in favour
of using setup_intf_cfg_v1 when CTL_ACTIVE_CFG is set.
This solves continuous timeouts on at least the Qualcomm sm6125 SoC:
[drm:dpu_encoder_frame_done_timeout:2091] [dpu error]enc31 frame done timeout
[drm:_dpu_encoder_phys_cmd_handle_ppdone_timeout.isra.0] *ERROR* id:31 pp:0 kickoff timeout 0 cnt 1 koff_cnt 1
[drm:dpu_encoder_phys_cmd_prepare_for_kickoff] *ERROR* failed wait_for_idle: id:31 ret:-110 pp:0
In the same way this pingpong block should also be unbound followed by
an interface flush when the encoder is disabled, according to the
downstream display driver [2].

DPU driver never supported INTF_EDP, so let's drop the obsolete comment.
If at some point 8x74/8x84's INTF_EDP is ported to DPU driver,

This enum value does not correspond to any of actual interface types,

Based on the discussions on the mailing list, document enum
dpu_intf_type and it's controversial fields: INTF_DP and INTF_EDP.
INTF_EDP is used for older eDP interface found on msm8x74/msm8x84
INTF_DP is used for both eDP and DP interfaces handled by the msm/dp
driver. The DPU driver does not make a difference between them.

Pull clk fixes from Stephen Boyd:
"A semi-large pile of clk driver fixes this time around.
Nothing is touching the core so these fixes are fairly well contained
to specific devices that use these clk drivers.
- Some Allwinner SoC fixes to gracefully handle errors and mark an
RTC clk as critical so that the RTC keeps ticking.
- Fix AXI bus clks and RTC clk design for Microchip PolarFire SoC
driver introduced this cycle. This has some devicetree bits acked
by riscv maintainers. We're fixing it now so that the prior
bindings aren't released in a major kernel version.
- Remove a reset on Microchip PolarFire SoCs that broke when enabling
CONFIG_PM.
- Set a min/max for the Qualcomm graphics clk. This got broken by the
clk rate range patches introduced this cycle"

Compute engines have a separate register that the driver should use to
perform MMIO-based TLB invalidation.
Note that the term "context" in this register's bspec description is
used to refer to the engine instance (in the same way "context" is used
on bspec 46167).

This reverts commit 0dc23d1a8e17, which caused another regression
as the pinctrl code actually expects an integer value of 0 or 1
rather than a simple boolean property.
