regulator: anatop: set default voltage selector for pcie
Set the initial voltage selector for vddpcie in case it's disabled by default. This fixes the below warning: 20c8000.anatop:regulator-vddpcie: Failed to read a valid default voltage selector. anatop_regulator: probe of 20c8000.anatop:regulator-vddpcie failed with error -22 Cc: Liam Girdwood <lgirdwood@gmail.com> Cc: Mark Brown <broonie@kernel.org> Cc: Shawn Guo <shawnguo@kernel.org> Cc: Sascha Hauer <kernel@pengutronix.de> Cc: Robin Gong <yibin.gong@nxp.com> Cc: Richard Zhu <hongxing.zhu@nxp.com> Signed-off-by: Richard Zhu <hongxing.zhu@nxp.com> Signed-off-by: Dong Aisheng <aisheng.dong@nxp.com> Signed-off-by: Mark Brown <broonie@kernel.org>
