amdxdna_flush() was introduced to ensure that the device does not access
a process address space after it has been freed. However, this is no
longer necessary because the driver now increments the mm reference count
when a command is submitted and decrements it only after the command has
completed. This guarantees that the process address space remains valid
for the entire duration of command execution. Remove amdxdna_flush to
simplify the teardown path.

This patch removes the MCU halt and wait for halt procedures during
panthor_fw_unplug() as the MCU can be in a variety of states or the FW
may not even be loaded/initialized at all, the latter of which can lead
to a NULL pointer dereference.
It should be safe on unplug to just disable the MCU without waiting for
it to halt as it may not be able to.

helpers, as recommended in Documentation/gpu/todo.rst. The multi
variants provide proper error accumulation and handle the required
DCS NOP insertions, which suits the OTM8009A command sequences.
Refactor otm8009a_dcs_write_buf() and the dcs_write_seq/dcs_write_cmd_at
macros to take a mipi_dsi_multi_context pointer, passing it through
from callers. This ensures consistent error handling throughout the
driver.
Replace all mdelay() and msleep() calls within DSI command sequences
with mipi_dsi_msleep() for proper error accumulation.
The init, disable, and backlight update paths now return dsi_ctx.accum_err,

Add MIPI DSI support for the Renesas RZ/V2H(P) SoC. Compared to the
RZ/G2L family, the RZ/V2H(P) requires dedicated D-PHY PLL programming,
different clock configuration, and additional timing parameter handling.
The driver introduces lookup tables and helpers for D-PHY timings
(TCLK*, THS*, TLPX, and ULPS exit) as specified in the RZ/V2H(P) hardware
manual. ULPS exit timing depends on the LPCLK rate and is now handled
explicitly.
The implementation also adds support for 16 bpp RGB format, updates the
clock setup path to use the RZ/V2H PLL divider limits, and provides new
.dphy_init, .dphy_conf_clks, and .dphy_startup_late_init callbacks to
match the RZ/V2H sequence.
With these changes, the RZ/V2H(P) can operate the MIPI DSI interface in
compliance with its hardware specification while retaining support for
existing RZ/G2L platforms.

Add the compatible string "renesas,r9a09g057-mipi-dsi" for the Renesas
RZ/V2H(P) (R9A09G057) SoC. While the MIPI DSI LINK registers are shared
with the RZ/G2L SoC, the D-PHY register layout differs. Additionally, the
RZ/V2H(P) uses only two resets compared to three on RZ/G2L, and requires
five clocks instead of six.
To reflect these hardware differences, update the binding schema to
support the reduced clock and reset requirements for RZ/V2H(P).
Since the RZ/V2N (R9A09G056) SoC integrates an identical DSI IP to
RZ/V2H(P), the same "renesas,r9a09g057-mipi-dsi" compatible string is
reused for RZ/V2N.

Stop open coding pending job list in drivers. Add pending job list
iterator which safely walks DRM scheduler list asserting DRM scheduler
is stopped.

In the past, drivers used to reach into scheduler internals—this must
end because it makes it difficult to change scheduler internals, as
driver-side code must also be updated.
Add helpers to check if the scheduler is stopped and to query a job’s
signaled state to avoid reaching into scheduler internals. These are
expected to be used driver-side in recovery and debug flows.
