2018-10-23mfd: mc13xxx-core: Fix PMIC shutdown when reading ADC valuesFabio Estevam2-1/+3
When trying to read any MC13892 ADC channel on a imx51-babbage board: The MC13892 PMIC shutdowns completely. After debugging this issue and comparing the MC13892 and MC13783 initializations done in the vendor kernel, it was noticed that the CHRGRAWDIV bit of the ADC0 register was not being set. This bit is set by default after power on, but the driver was clearing it. After setting this bit it is possible to read the ADC values correctly.

2018-10-23mfd: madera: Remove unused forward referenceRichard Fitzgerald1-1/+0
The madera_irqchip_pdata struct was replaced by the irq_flags member of struct madera_pdata so the forward reference is obsolete. Signed-off-by: Richard Fitzgerald <rf@opensource.cirrus.com> Signed-off-by: Lee Jones <lee.jones@linaro.org>
2018-10-23mfd: max77620: Convert to using %pOFn instead of device_node.nameRob Herring1-1/+1
In preparation to remove the node name pointer from struct device_node, convert printf users to use the %pOFn format specifier. Signed-off-by: Rob Herring <robh@kernel.org> Signed-off-by: Lee Jones <lee.jones@linaro.org>
2018-10-23mfd: madera: Don't use regmap_read_poll_timeout to poll for BOOT_DONERichard Fitzgerald1-13/+20
While polling for BOOT_DONE the chip could NAK a read because it is still booting, which would terminate the regmap_read_poll_timeout() with an error. Instead implement a polling loop that ignores read errors so we always poll until the chip signals boot or the loop times out.

2018-10-23mfd: arizona: Correct calling of runtime_put_syncSapthagiri Baratam1-4/+4
Don't call runtime_put_sync when clk32k_ref is ARIZONA_32KZ_MCLK2 as there is no corresponding runtime_get_sync call. MCLK1 is not in the AoD power domain so if it is used as 32kHz clock source we need to hold a runtime PM reference to keep the device from going into low power mode.
