Subject: [PATCH v3 0/3] Introduce EBBG FT8719 DRM panel driver

Add bindings and DRM panel driver for EBBG FT8719 6.18" 2246x1080 DSI
video mode panel, which can be found on some Xiaomi Poco F1 phones.
The panel's backlight is managed through QCOM WLED driver.

The driver is built using linux-mdss-dsi-panel-driver-generator[1], and
additionally support for handling regulators and linking external
backlight is added.

Changes in v3: (Mostly Linus Walleij's Suggestions)
 - Removed ctx->prepared state variable as it's handled by the core
 - Print error in dsi_dcs_write_seq macro if it fails to write
 - Removed magic power on sequences as panel works fine without them

Changes in v2: (Krzysztof Kozlowski's Suggestions)
 - dt-bindings: specify maxItems for reg
 - dt-bindings: cleanup and simplify the panel properties
 - dt-bindings: in example change "|+" to "|' and "dsi0" to "dsi"

Joel Selvaraj (3):
  dt-bindings: vendor-prefixes: Add prefix for EBBG
  dt-bindings: display: Add bindings for EBBG FT8719
  drm/panel: introduce ebbg,ft8719 panel
