The series adds drivers for the displays used by bsh-smm-s2/pro boards.
This required applying some patches to the samsung-dsim driver and the
drm_bridge.c module.
Changes in v8:
- Move the 'status' property to the end of the list of nodes:
- pwm1
- lcdif
- mipi_dsi
- Add a newline between properties and child node (mipi_dsi_out).
- Sort the iomuxc node alphabetically
- Rename pwm1grp to blgrp
Changes in v7:
- Drop [3/4] dt-bindings: display: panel: Add synaptics r63353 panel controller
because applied.
Changes in v6:
- Drop patches:
- [06/10] drm/panel: Add Synaptics R63353 panel driver
- [07/10] dt-bindings: display: panel: Add Ilitek ili9805 panel controller
- [08/10] drm/panel: Add Ilitek ILI9805 panel driver
- [09/10] drm/panel: ilitek-ili9805: add support for Tianma TM041XDHG01 panel
Because applied to https://anongit.freedesktop.org/git/drm/drm-misc.git (drm-misc-next)
Drop patches:
- [01/10] drm/bridge: Fix bridge disable logic
- [02/10] drm/bridge: Fix a use case in the bridge disable logic
Because they are wrong
Changes in v3:
- Replace "synaptics,r63353" compatible with "syna,r63353", as
required by vendor-prefixes.yaml.
- Squash patch [09/11] dt-bindings: ili9805: add compatible string for Tianma TM041XDHG01
into [07/11] dt-bindings: display: panel: Add Ilitek ili9805 panel controller.
Changes in v2:
- Adjust the mipi_dsi node based on the latest patches merged into
the mainline in the dtsi files it includes.
- Added to the series the following patches:
- 0001 drm/bridge: Fix bridge disable logic
- 0002 drm/bridge: Fix a use case in the bridge disable logic
- 0003 samsung-dsim: enter display mode in the enable() callback
- 0004 drm: bridge: samsung-dsim: complete the CLKLANE_STOP setting

drm: bridge: samsung-dsim: enter display mode in the enable() callback
