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 <[email protected]> Cc: Mark Brown <[email protected]> Cc: Shawn Guo <[email protected]> Cc: Sascha Hauer <[email protected]> Cc: Robin Gong <[email protected]> Cc: Richard Zhu <[email protected]> Signed-off-by: Richard Zhu <[email protected]> Signed-off-by: Dong Aisheng <[email protected]> Signed-off-by: Mark Brown <[email protected]> Signed-off-by: Sasha Levin <[email protected]> --- drivers/regulator/anatop-regulator.c | 5 +++++ 1 file changed, 5 insertions(+) diff --git a/drivers/regulator/anatop-regulator.c b/drivers/regulator/anatop-regulator.c index 3a6d0290c54c..c5e272ea4372 100644 --- a/drivers/regulator/anatop-regulator.c +++ b/drivers/regulator/anatop-regulator.c @@ -296,6 +296,11 @@ static int anatop_regulator_probe(struct platform_device *pdev) if (!sreg->sel && !strcmp(sreg->name, "vddpu")) sreg->sel = 22; + /* set the default voltage of the pcie phy to be 1.100v */ + if (!sreg->sel && rdesc->name && + !strcmp(rdesc->name, "vddpcie")) + sreg->sel = 0x10; + if (!sreg->bypass && !sreg->sel) { dev_err(&pdev->dev, "Failed to read a valid default voltage selector.\n"); return -EINVAL; -- 2.14.1
