This patch add support for the Mediatek MT2712 DISP subsystem.
MT2712 is base on MT8173, there are some difference as following:
MT2712 support three disp output(two ovl and one rdma)
Change in v4:
- Move some modification about AAL1 from patch
"Add support for mediatek SOC MT2712" to
"add ddp component AAL1"
- Move some modification about OD1 from patch
"Add support for mediatek SOC MT2712" to
"add ddp component OD1"
- Move some modification about PWM2 from patch
"Add support for mediatek SOC MT2712" to
"add ddp component PWM2"
- Move some modification about third ddp path from patch
"Add support for mediatek SOC MT2712" to
"add third ddp path"
- Move the definition OD1_MOUT_EN_RDMA1 from patch
"Add support for mediatek SOC MT2712" to
"add connection from OD1 to RDMA1"
- Rebase the patch "add connection from OD1 to RDMA1" after
"add ddp component OD1"
- Rebase the patch "add third ddp path" before
"Add support for mediatek SOC MT2712"
- Modify the 2712 MUTEX MODULE in the order by index
- Added patch for ddp component PWM1
- For patch "add third ddp path"
Add the condition in mtk_crtc_create() that if there
is no ddp path, then return 0 to avoid the null crtc
Change in v3:
- Added patch for ddp component AAL1
- Added patch for ddp component OD1
- Added patch for ddp component PWM2
- Added patch to create third ddp path
- Rebase patch "support maximum 64 mutex mod" before
"Add support for mediatek SOC MT2712"
- Rebase patch "add connection from OD1 to RDMA1" before
"Add support for mediatek SOC MT2712"
- Remove two definition about RDMA0 and RDMA2
- Change the definition about mutex module from
bitwise to index
Changes in v2:
- update dt-bindings for mt2712
- Added patch to connection from OD1 to RDMA1
- Added patch to support maximum 64 mutex mod
- rewrite mutex mod condition for reducing one byte
- Change the component name AAL/OD to AAL0/OD0 for naming consistency
- Move the compatible information about dpi to other patch which modify
the dpi driver for mt2712
Stu Hsieh (9):
drm/mediatek: update dt-bindings for mt2712
drm/mediatek: support maximum 64 mutex mod
drm/mediatek: add ddp component AAL1
drm/mediatek: add ddp component OD1
drm/mediatek: add ddp component PWM1
drm/mediatek: add ddp component PWM2
drm/mediatek: add connection from OD1 to RDMA1
drm/mediatek: add third ddp path
drm/mediatek: Add support for mediatek SOC MT2712
