From: Lisa Du <cldu@xxxxxxxxxxx> Add tpo hvga panel support in marvell display framework. This panel driver implements modes query and on/off commands by spi. This panel driver also get panel config/ plat power on/off/ connected path name from machine-info. This panel driver uses mmp_disp supplied register_panel function to register panel to path as machine-info defined.
