Hi all,

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


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 4 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 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
