This leads to a 3.3V IO +and 1.2V CVDD voltage. + +For the TPS6507x driver, it means that the DEFDCDC_HIGH registers +need to be read/written instead of DEFDCDC_LOW register. The tps6507x +driver added this functionality recently. This patch passes the right +platform data to the TPS6507x which tells it that the HIGH register +needs to be read instead of the LOW register. + +Signed-off-by: Sekhar Nori <nsekhar@ti.com> +--- + +diff --git a/arch/arm/mach-davinci/board-da850-evm.c b/arch/arm/mach-davinci/board-da850-evm.c +index 607dd2d..9ed07d6 100755 +--- a/arch/arm/mach-davinci/board-da850-evm.c ++++ b/arch/arm/mach-davinci/board-da850-evm.c +@@ -599,6 +599,7 @@ struct regulator_init_data tps65070_regulator_data[] = { + }, + .num_consumer_supplies = ARRAY_SIZE(tps65070_dcdc2_consumers), + .consumer_supplies = tps65070_dcdc2_consumers, ++ .driver_data = (void *) 1, + }, + + /* dcdc3 */ +@@ -612,6 +613,7 @@ struct regulator_init_data tps65070_regulator_data[] = { + }, + .num_consumer_supplies = ARRAY_SIZE(tps65070_dcdc3_consumers), + .consumer_supplies = tps65070_dcdc3_consumers, ++ .driver_data = (void *) 1, + }, + + /* ldo1 */ |
