Brian Norris	9bf7123bb0	drm/panel: Delete panel on mipi_dsi_attach() failure ... Many DSI panel drivers fail to clean up their panel references on mipi_dsi_attach() failure, so we're leaving a dangling drm_panel reference to freed memory. Clean that up on failure. Noticed by inspection, after seeing similar problems on other drivers. Therefore, I'm not marking Fixes/stable.

Sumit Semwal	070c7fa58b	drm: panel: Add novatek nt36672a panel driver ... Novatek NT36672a is a generic DSI IC that drives command and video mode panels. Add the driver for it. Right now adding support for some Poco F1 phones that have an LCD panel from Tianma connected with this IC, with a resolution of 1080x2246 that operates in DSI video mode. During testing, Benni Steini <bennisteinir@gmail.com> helped us fix the reset sequence timing (from 10ms to 20ms), to get the bootanimation to work on Android. With current AOSP, we need to increase it to 200ms - this seems to be a safe high value to avoid a white screen occasionally.
