Subject: [PATCH v14 00/10] support gce on mt8183 platform

Changes since v13:
 - separate poll function as poll w/ & w/o mask function
 - directly pass inst into append_command function instead
   of returns a pointer
 - fixup coding style
 - rebase onto 5.3-rc1

Changes since v12:
 - clear the value of command ptr address
 - fixup some typo and remove unused define

Changes since v11:
 - correct some data type to avoid type conversion

Changes since v10:
 - remove subsys-cell from gce device node
 - use of_parse_phandle_with_fixed_args instead of
   of_parse_phandle_with_args

Changes since v8 and v9:
 - change the error return code in cmdq_dev_get_client_reg()

Changes since v7:
 - remove the memory allocation out of cmdq_dev_get_client_reg()
 - rebase onto 5.2-rc1

Changes since v6:
 - remove cmdq_dev_get_event function and gce event property
 - separate some changes to indepentent patch
 - change the binding document related to gce-client-reg property

Changes since v5:
 - fix typo
 - remove gce-event-name form the dt-binding
 - add reasons in commit message

Changes since v4:
 - refine the architecture of the packet encoder function
 - refine the gce enevt property
 - change the patch's title

Changes since v3:
 - fix a typo in dt-binding and dtsi
 - cast the return value to right format

Changes since v2:
 - according to CK's review comment, change the property name and
   refine the parameter
 - change the patch's title
 - remove unused property from dt-binding and dts

Changes since v1:
 - add prefix "cmdq" in the commit subject
 - add dt-binding document for get event and subsys function
 - add fix up tag in fixup patch
 - fix up some coding style (alignment)

MTK will support gce function on mt8183 platform.
  dt-binding: gce: add gce header file for mt8183
  mailbox: mediatek: cmdq: support mt8183 gce function
  arm64: dts: add gce node for mt8183

Besides above patches, we refine gce driver on those patches.
  mailbox: mediatek: cmdq: move the CMDQ_IRQ_MASK into cmdq driver data
  mailbox: mediatek: cmdq: clear the event in cmdq initial flow

In order to enhance the convenience of gce usage, we add new helper functions and refine the method of instruction combining.
  dt-binding: gce: remove thread-num property
  dt-binding: gce: add binding for gce client reg property
  soc: mediatek: cmdq: define the instruction struct
  soc: mediatek: cmdq: add polling function
  soc: mediatek: cmdq: add cmdq_dev_get_client_reg function
