Mark indicated a preference to set this on a per-system basis instead of blitzing it, as in downstream. Looking at what was upstream versus what was in my working tree I saw that in fact the VBUS boost driver had been upstreamed minus accompanying DTS in pm8150b. So there's no need for a fixes as this driver doesn't appear to be in use. A subsequent patchset will enable the VBUS boost for the two relevant upstream platforms. First thing though, is the driver + dts change. - Use regulator_set_current_limit_regmap/regulator_get_current_limit_regmap with a relevant current-to-bitmap lookup. - Add a parallel DTS entry to the pm8150b It looks like this was submitted upstream but not followed up on I've add regulator-min-microamp/regulator-max-microamp to Wesley's original work. I've made sure to test that its possible to set the current to anything in the range of 500 mA to 3 A and confirmed the output on a scope. Once these two patches are in, I'll send out board enablement for the sm8150-mtp and qrb5165-rb5. https://firstname.lastname@example.org/T/#t Bryan O'Donoghue (1): regulator: Add a routine to set the current limit for QCOM PMIC VBUS Wesley Cheng (1): arm64: boot: dts: qcom: pm8150b: Add DTS node for PMIC VBUS booster arch/arm64/boot/dts/qcom/pm8150b.dtsi | 6 ++++++ drivers/regulator/qcom_usb_vbus-regulator.c | 12 ++++++++++++ 2 files changed, 18 insertions(+) -- 2.30.1
