Subject: [PATCH v3 0/7] Add GCE support for MT8196

From: Jason-jh Lin <jason-jh.lin@...iatek.corp-partner.google.com>

This patch series adds support for the MediaTek MT8196 SoC in the CMDQ
driver and related subsystems. The changes include adding compatible
names and properties, updating driver data to accommodate hardware
changes, and modifying the usage of CMDQ APIs to support non-subsys ID
hardware.

---

Change in v3:
1. Merge 2 dt-bindings pathes together and add more detail commit message.
2. Change type u32 to phys_addr_t for pa_base of struct cmdq_client_reg.
3. Remove cmdq_subsys_is_valid() and subsys_num in CMDQ driver.
4. Add CMDQ_SUBSYS_INVALID to check subsys instead of using
   cmdq_subsys_is_invalid().
5. Make use of CMDQ_THR_SPR0 define to the parameter of CMDQ APIs.
6. Rebase on the new MACRO in mtk-mdp3-comp.h.

Change in v2:
1. Remove the constant and fix warning in dt-bindings.
2. Remove the pa_base parameter of CMDQ APIs and related modification.
3. Move subsys checking to client drivers and use 2 alternative
   CMDQ APIs to achieve the same functionality.
