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 v6: Fixed few review comments on v5 from Sam: - add dev_err_probe() support - move DRM_* error printing to dev_err() - removed a few unnecessary bits v7: Fixed review comments on v6 from Bjorn: - Reworked the send_mipi_commands functionality - removed regulator disable_loads; moved active_load setting to probe time - made function names and struct less generic - updated the reset_gpio working to active_low - update MAINTAINERS for file name changes
