[08/10] ARM: tegra: Enable DSI support on Dalmore

Commit Message

Thierry Reding Dec. 19, 2013, 3:59 p.m. UTC

Dalmore has a 10.1" WUXGA panel connected to one of the DSI outputs of
the Tegra114.

Signed-off-by: Thierry Reding <[e-mail]>

Changes in v3:
- make panel a peripheral on the DSI bus

Changes in v2:
- remove backlight-boot-off property for now
- don't renumber all regulators
