- support both voltage register address and command register address for each VC channel - add fields for voltage register address (volra) and command register address (cmdra) to struct omap_vc_channel - use VC/VP register access read/modify/write helper - remove volra_shift field (use __ffs(mask) for shift value) - I2C addresses 10-bit, change size to u16 Signed-off-by: Kevin Hilman <khilman@ti.com>
