MACHINE_START(ORIGEN, "ORIGEN")
ORIGEN board is fitted with 7" LCD panel HV070WSA. The pixel resolution of the LCD panel is 1024x600. Also power domain device for LCD0 is registered. Signed-off-by: Tushar Behera <tushar.behera@linaro.org> --- Changes for V3: * Added error check for gpio request in LCD power function Changes for V2: * Added power domain device registration for LCD0 The patch is rebased on [1]. For proper working of LCD on ORIGEN, following patches are needed. These patches are already submitted to the mailing list. a.
