Subject: [PATCH v3 0/9] Add TOSHIBA TC358764 DSI/LVDS bridge driver

Hi all,

this patchset is a next attempt to add the tc358764 driver.
The previous one can be found here:

https://lists.freedesktop.org/archives/dri-devel/2014-February/053705.html

Back then, TC358764 was added as a panel driver.

The bridge is supposed to be a DSI peripheral. Currently exynos_dsi accepts only panels
as its peripherals. Therefore, some logic in exynos_dsi had to be ammended. That is implemented
in first 3 patches.

Apart from the driver this patchset adds support for BOE HV070WSA-100 panel, which is used by
TC358764 and dts nodes to exynos5250.dtsi and exynos5250-arndale.dtsi.

Best regards,

Maciej Purski

Changes in v3:
- call drm_bridge_enable() and drm_bridge_pre_enable() in exynos_drm_dsi_enable()
  and make the bridge invisible for the framework in order to prevent it from
  being enabled by the framework
- expand panel binding description
- fix tc358744 binding, make port 1 mandatory and port 0 optional
- get rid of useless select VIDEOMODE_HELPERS in bridge Kconfig
- add missing SPDX license to drm/bridge/tc358764.c
- use mipi_dsi_generic_read() and mipi_dsi_generic_write() helpers
  in toshiba driver's read, write functions
- fix commit messages

Changes in v2:
- fix commits authorship
- don't call pm_runtime_put_sync() in exyons_dsi_disable(), if pm_runtime_get_sync()
  has not been called
- squash dts commits
- merge some redundant regulators in tc358764 bindings and in DTS
- fix kbuild robot errors
