This watchdog can't be used with Linux because the firmware needs it on
R-Car V3H boards. Sadly, it doesn't mark the node as reserved, so this
is added manually here.

The Renesas RZ/V2N SoC includes a Thermal Sensor Unit (TSU) block designed
to measure the junction temperature. The device provides real-time
temperature measurements for thermal management, utilizing two dedicated
channels for temperature sensing:
- TSU0, which is located near the DRP-AI block
- TSU1, which is located near the CPU and DRP-AI block
Since TSU1 is physically closer the CPU and the highest temperature
spot, it is used for CPU throttling through a passive trip and cooling
map. TSU0 is configured only with a critical trip.
Add TSU nodes along with thermal zones and keep them enabled in the SoC
DTSI.

A jack detection work that is unscheduled or in progress while executing
the suspend handler could trigger a race condition.
Ensure state consistency by cancelling any pending work or wait for its
execution to complete before processing the suspend. Since driver
(re)enables both insert and eject interrupts on resume, there is no risk
to miss the related jack events. Therefore, flush_delayed_work() is not
required here.

The DAPM routes for "Left Line Mux" and "Right Line Mux" are defined
twice in es8328_dapm_routes[]. The redundant entries appear after
the "Mic Bias" route and duplicate the definitions found earlier in
the array.
Remove the duplicate entries to clean up the code.
Tested on Rockchip RK3588 with ES8328 codec. Verified that removing
the duplicate routes does not alter the DAPM graph or the mixer
controls. Both 'tinymix' output and DAPM widget lists remain
identical to the baseline.

The ALC5575 integrates an audio DSP that typically loads its firmware
from an external flash via its own SPI host interface. In certain
hardware configurations, the firmware can alternatively be loaded
through the SPI client interface. The driver provides basic mute and
volume control functions. When the SPI client interface is enabled,
firmware loading is handled by the SPI driver.
