The operation conditions register (OCR) stores the voltage profile of the card, however the list of possible voltages is restricted by the voltage range supported by the supply used as VCC/VDD. So in mmc_vddrange_to_ocrmask() a OCR mask is obtained to filter the not supported voltages, from the value read in the host controller OCR register. For fixed regulators, regulator_list_voltage() returns the fixed output for the first selector but this doesn't happen for switch (FET) regulators that obtain their voltage from their parent supply. A call to regulator_get_voltage() is needed in this case so the regulator core can return the FET's parent supply voltage output. This change is consistent with the fact that for other fixed regulators (that are not FETs) the OCR mask is returned even when mmc_regulator_set_ocr() checks if the regulator is fixed before calling regulator_set_voltage(). Without this patch, the following warning is reported when a FET is used as a vmmc-supply: dwmmc_exynos 12220000.mmc: Failed getting OCR mask: -22 Signed-off-by: Javier Martinez Canillas <javier.martinez@collabora.co.uk> Signed-off-by: Ulf Hansson <ulf.hansson@linaro.org> |
