[PATCH v2 5/6] iio: light: stk3310: log error if reading the chip id fails

If the chip isn't powered, this call is likely to return an error. Without a log here the driver will silently fail to probe. Common errors are ENXIO (when the chip isn't powered) and ETIMEDOUT (when the i2c bus isn't powered). Signed-off-by: Aren Moynihan --- Notes: Changes in v2

[PATCH v2 6/6] arm64: dts: allwinner: pinephone: Add power supplies to stk3311

From: Ondrej Jirman This makes the driver disable the supply during sleep. Signed-off-by: Ondrej Jirman Signed-off-by: Aren Moynihan --- Notes: Changes in v2: - add leda-supply arch/arm64/boot/dts/allwinner/sun50i-a64-pinephone.dtsi | 2 ++ 1 file changed, 2 insertions(+) diff

[PATCH v2 3/6] iio: light: stk3310: Manage LED power supply

The stk3310 and stk3310 chips have an input for power to the infrared LED. Add support for managing it's state. Signed-off-by: Aren Moynihan --- drivers/iio/light/stk3310.c | 23 ++- 1 file changed, 22 insertions(+), 1 deletion(-) diff --git a/drivers/iio/light/stk3310.c b

[PATCH v2 2/6] iio: light: stk3310: Implement vdd supply and power it off during suspend

From: Ondrej Jirman VDD power input can be used to completely power off the chip during system suspend. Do so if available. Signed-off-by: Ondrej Jirman Signed-off-by: Aren Moynihan --- Notes: Changes in v2: - always enable / disable regulators and rely on a dummy regulator

[PATCH v2 0/6] iio: light: stk3310: support powering off during suspend

is more likely to cause issues than including it. - Convert stk3310 to use dev_err_probe for errors. - Always enable / disable regulators and rely on dummy devices if they're not specified. - more listed in individual patches Aren Moynihan (4): dt-bindings: iio: light: stk33xx: add vdd

[PATCH v2 1/6] dt-bindings: iio: light: stk33xx: add vdd and leda regulators

stk3310 and stk3311 are typically connected to power supplies for the chip (vdd) and the infrared LED (leda). Add properties so we can power these up / down appropriately. Signed-off-by: Aren Moynihan --- Notes: Changes in v2: - add leda-supply - add supplies to examples

[PATCH v2 4/6] iio: light: stk3310: use dev_err_probe where possible

Using dev_err_probe instead of dev_err and return makes the errors easier to understand by including the error name, and saves a little code. Signed-off-by: Aren Moynihan --- Notes: Added in v2 drivers/iio/light/stk3310.c | 44 + 1 file changed, 20
