Subject: [PATCH v5 0/2] Add support for Tianma nt36672a video mode panel
Date: Wed, 26 Aug 2020 21:33:06 +0530 [thread overview]
Message-ID: <20200826160308.18911-1-sumit.semwal@linaro.org> (raw)
Some Poco F1 phones from Xiaomi have a FHD+ video mode panel based on the
Novatek NT36672A display controller; Add support for the same.
Most of the panel data is taken from downstream panel dts, and is converted to
drm-panel based driver by me.
It has been validated with v5.9-rc1 based drm-misc-next on Poco F1 phone; my tree with other
dependent patches is here [1]

v2: In dt-binding, removed ports node, making port@0 directly under panel@0 node.
Also updated the panel_on delay to a safer 200ms as needed for latest Android.
v3: Replaced port@0 with just port in panel@0 node.
v4: Since "0425662fdf05: drm: Nuke mode->vrefresh", we have to calculate
vrefresh on demand. Update for it.
v5: Fixed review comments from Sam:
- rebased on top of drm-misc-next
remove return of drm_panel_add()
remove drm_panel_detach()
- renamed the panel driver file to reflect that this is a novatek
nt36672a display driver and not only for tianma panels.
Adjusted some internal names also to reflect the same.
- corrected changelog to add info about the generic Novatek DSI IC
- corrected compatible string accordingly
- removed pinctrl
- used drm_panel* API for prepare/unprepare/disable/remove
