Subject: [PATCH v6 0/3] Introduce STM32 LVDS driver

This serie introduces a new DRM bridge driver for STM32MP257 platforms
based on Arm Cortex-35. It also adds an instance in the device-tree and
handle the inclusion of the driver within the DRM framework. First patch
adds a new panel compatible in the panel-lvds driver, which is used by
default on the STM32MP257.

Changes in v6:
	- [1/3] Added Conor's Reviewed-by
	- [2/3] Fixed kernel test robot warnings
	- Rebased on latest drm-misc-next

Changes in v5:
	- Fixed path in MAINTAINERS
	- Fixed compatible in driver

Changes in v4:
	- Align dt-bindings filename and compatible
	- Remove redundant word in [1/6] subject
	- Fix example on typo
	- Some minor fixes on YAML syntax
	- Explicitly include linux/platform_device.h
	- Drop device-tree related patch after internal discussions
	- Rebase on latest drm-misc-next

Changes in v3:
	- Changed the compatible to show SoC specificity
	- Fixed includes in dt-binding example
	- Added "#clock-cells" description in dt-binding example
	- Some minor fixes on typo

Changes in v2:
	- Dropped [1/8] because already merged
	- Dropped [4/8] since not mandatory for this serie
	- [1/6]: Switch compatible and clock-cells related areas
	- [1/6]: Remove faulty #include in the example.
	- [1/6]: Add missing entry in MAINTAINERS
	- [2/6]: Removed CamelCase macros
	- [2/6]: Removed hard to read debug log
	- [3/6]: Fixed my address
	- [3/6]: Fixed smatch warning
	- [5/6]: Move changes to stm32mp255.dtsi
