This patchset enables the display on the OnePlus 6T smartphone.
Patches 1-2 add the bindings and the panel driver.
Patches 3-6 document the panel, pinctrls, and GPIOs.
Patch 7 removes the compatible entry from the simple DSI panel.
Since the display node is shared between the OnePlus 6 and 6T,
the following warning appears:
..sdm845-oneplus-enchilada.dtb: panel@0 (samsung,sofef00): 'poc-supply', 'te-gpios', 'vci-supply' do not match any of the regexes: '^pinctrl-[0-9]+$'
This will be addressed in a follow-up patch, as the SOFEF00 DDIC also
requires additional overhaul to properly initialize and function in mainline.
