-MediaTek GCE
-===============
-
-The Global Command Engine (GCE) is used to help read/write registers with
-critical time limitation, such as updating display configuration during the
-vblank. The GCE can be used to implement the Command Queue (CMDQ) driver.
-
-CMDQ driver uses mailbox framework for communication. Please refer to
-mailbox.txt for generic information about mailbox device-tree bindings.
-
-Required properties:
-- compatible: can be "mediatek,mt8173-gce", "mediatek,mt8183-gce",
- "mediatek,mt8186-gce", "mediatek,mt8192-gce", "mediatek,mt8195-gce" or
- "mediatek,mt6779-gce".
-- reg: Address range of the GCE unit
-- interrupts: The interrupt signal from the GCE block
-- clock: Clocks according to the common clock binding
-- clock-names: Must be "gce" to stand for GCE clock
-- #mbox-cells: Should be 2.
- <&phandle channel priority>
- phandle: Label name of a gce node.
- channel: Channel of mailbox. Be equal to the thread id of GCE.
- priority: Priority of GCE thread.
-
-Required properties for a client device:
-- mboxes: Client use mailbox to communicate with GCE, it should have this
- property and list of phandle, mailbox specifiers.
-Optional properties for a client device:
-- mediatek,gce-client-reg: Specify the sub-system id which is corresponding
- to the register address, it should have this property and list of phandle,
- sub-system specifiers.
- <&phandle subsys_number start_offset size>
- phandle: Label name of a gce node.
- subsys_number: specify the sub-system id which is corresponding
- to the register address.
- start_offset: the start offset of register address that GCE can access.
- size: the total size of register address that GCE can access.
-
-Optional properties for a client mutex node:
-- mediatek,gce-events: GCE events used by clients. The event numbers are
- defined in 'dt-bindings/gce/<chip>-gce.h'.
-
-Some vaules of properties are defined in 'dt-bindings/gce/mt8173-gce.h',
-'dt-bindings/gce/mt8183-gce.h', 'dt-bindings/gce/mt8186-gce.h'
-'dt-bindings/gce/mt8192-gce.h', 'dt-bindings/gce/mt8195-gce.h' or
-'dt-bindings/gce/mt6779-gce.h'.
-Such as sub-system ids, thread priority, event ids.
-
-Example:
-
- gce: gce@10212000 {
- compatible = "mediatek,mt8173-gce";
- reg = <0 0x10212000 0 0x1000>;
- interrupts = <GIC_SPI 135 IRQ_TYPE_LEVEL_LOW>;
- clocks = <&infracfg CLK_INFRA_GCE>;
- clock-names = "gce";
- #mbox-cells = <2>;
- };
-
-Example for a client device:
-
- mmsys: clock-controller@14000000 {
- compatible = "mediatek,mt8173-mmsys";
- mboxes = <&gce 0 CMDQ_THR_PRIO_LOWEST>,
- <&gce 1 CMDQ_THR_PRIO_LOWEST>;
- mutex-event-eof = <CMDQ_EVENT_MUTEX0_STREAM_EOF
- CMDQ_EVENT_MUTEX1_STREAM_EOF>;
- mediatek,gce-client-reg = <&gce SUBSYS_1400XXXX 0x3000 0x1000>,
- <&gce SUBSYS_1401XXXX 0x2000 0x100>;
- ...
- };
-
-Example for a client mutex node:
- mutex: mutex@14020000 {
- compatible = "mediatek,mt8173-disp-mutex";
- reg = <0 0x14020000 0 0x1000>;
- interrupts = <GIC_SPI 169 IRQ_TYPE_LEVEL_LOW>;
- power-domains = <&scpsys MT8173_POWER_DOMAIN_MM>;
- clocks = <&mmsys CLK_MM_MUTEX_32K>;
- mediatek,gce-events = <CMDQ_EVENT_MUTEX0_STREAM_EOF>,
- <CMDQ_EVENT_MUTEX1_STREAM_EOF>;
- };

Previous review tag? > I completely forgot that I had already sent something similar in the past, so that was done from scratch :\ I always keep note of what I send, what's accepted, what's not (etc) but, for some reason, that older series wasn't present in my notes. In any case, the older series wasn't just a dt schema conversion, but also changed how we got clocks from the driver, while this one is only a conversion and nothing else.
