It is enabled at bootloader itself since its required very early. Currently, the regulator_init_data struct for vcxio in board-4430sdp.c doesn't show any consumers. How can I implement regulator_enable/disable calls in my driver for a consumer of vcxio without disturbing the mpu and iva etc consumers which don't use regulator api to enable/disable the regulator at all. Also, is anyone aware why vcxio is tied to DSI in 4430sdp, would it be possible for some other omap4 board to have a different regulator supply for DSI? Thanks, Archit
