2022-09-15soc: mediatek: mutex: Add support for MT6795 Helio X10 display mutexAngeloGioacchino Del Regno
MT6795 has the same mutex mod/sof register layout as MT2712 and MT8173, but supports only four SOF, as it has two DSI and one DPI. Support is added by reusing most of the MT8173 data, with the addition of a mt6795-specific SOF array (and devicetree compatible, of course).

2022-07-08soc: mediatek: mutex: Simplify with devm_platform_get_and_ioremap_resource()AngeloGioacchino Del Regno
Convert platform_get_resource(), devm_ioremap_resource() to a single call to devm_platform_get_and_ioremap_resource(), as this is exactly what this function does. While at it, also remove a redundant call to of_address_to_resource(), as this was getting the address of the same resource index 0: we can as well get the iostart from the 'regs' pointer.

2022-06-22soc: mediatek: mutex: Use DDP_COMPONENT_DITHER0 mod index for MT8365AngeloGioacchino Del Regno
In commit 4e8988c634a1 ("soc: mediatek: add DDP_DOMPONENT_DITHER0 enum for mt8195 vdosys0") the enum mtk_ddp_comp_id was modified to add an index number to the DITHER component because some new SoCs have multiple dither blocks. As a result, all of the mutex mod arrays have been changed to use the new definition instead of the old one (even if that's retained): for consistency purposes, follow the same trend on the newly introduced MT8365 mutex mod array. This commit brings no functional changes.

2022-06-17soc: mediatek: mutex: add functions that operate registers by CMDQMoudy Ho
Due to HW limitations, MDP3 is necessary to enable MUTEX in each frame for SOF triggering and cooperate with CMDQ control to reduce the amount of interrupts generated(also, reduce frame latency). In response to the above situation, a new interface "mtk_mutex_enable_by_cmdq" has been added to achieve the purpose.

2022-06-17soc: mediatek: mutex: add common interface for modules settingMoudy Ho
In order to allow multiple modules to operate MUTEX hardware through a common interfrace, two flexible indexes "mtk_mutex_mod_index" and "mtk_mutex_sof_index" need to be added to replace original component ID so that like DDP and MDP can add their own MOD table or SOF settings independently. In addition, 2 generic interface "mtk_mutex_write_mod" and "mtk_mutex_write_sof" have been added, which is expected to replace the "mtk_mutex_add_comp" and "mtk_mutex_remove_comp" pair originally dedicated to DDP in the future.
