Lee Jones, For some strange reason this patch is missing! The other patch in the series is applied through mfd tree but somehow this particular patch is missed out. https://patchwork.kernel.org/patch/9420631/ is applied. https://patchwork.kernel.org/patch/9420655/ is not. I tried applying this very patch and it applies cleanly on the next branch. Let me know if you want me to send this again on top of latest next branch. - Keerthy > >> diff --git a/drivers/mfd/palmas.c b/drivers/mfd/palmas.c >> index ee9e9ea..da90124 100644 >> --- a/drivers/mfd/palmas.c >> +++ b/drivers/mfd/palmas.c >> @@ -430,6 +430,20 @@ static void palmas_power_off(void) >> { >> unsigned int addr; >> int ret, slave; >> + struct device_node *np = palmas_dev->dev->of_node; >> + >> + if (of_property_read_bool(np, "ti,palmas-override-powerhold")) { >> + addr = PALMAS_BASE_TO_REG(PALMAS_PU_PD_OD_BASE, >> + PALMAS_PRIMARY_SECONDARY_PAD2); >> + slave = PALMAS_BASE_TO_SLAVE(PALMAS_PU_PD_OD_BASE); >> + >> + ret = regmap_update_bits(palmas_dev->regmap[slave], addr, >> + PALMAS_PRIMARY_SECONDARY_PAD2_GPIO_7_MASK, 0); >> + if (ret) >> + dev_err(palmas_dev->dev, >> + "Unable to write PRIMARY_SECONDARY_PAD2 %d\n", >> + ret); >> + } >> >> slave = PALMAS_BASE_TO_SLAVE(PALMAS_PMU_CONTROL_BASE); >> addr = PALMAS_BASE_TO_REG(PALMAS_PMU_CONTROL_BASE, PALMAS_DEV_CTRL); >
