2018-01-08pinctrl: axp209: account for const type of of_device_id.dataJulia Lawall1-1/+1
The return value of of_device_get_match_data has type const void *. The desc field of the pctl structure also has a const type, so there is no need for the const-discarding cast between them. Done using Coccinelle. Signed-off-by: Julia Lawall <Julia.Lawall@lip6.fr> Signed-off-by: Linus Walleij <linus.walleij@linaro.org>
2017-12-20pinctrl: axp209: dereference pointer after it's been setQuentin Schulz1-1/+3
The number of GPIOs is gotten from a field within the structure referenced in the of_device.data but it was actually read before it was retrieved, thus it was dereferencing a null pointer. Set the number of GPIOs after retrieving of_device.data.

2017-12-07pinctrl: axp209: add support for AXP813 GPIOsQuentin Schulz1-8/+27
The AXP813 has only two GPIOs. GPIO0 can either be used as a GPIO, an LDO regulator or an ADC. GPIO1 can be used either as a GPIO or an LDO regulator. Moreover, the status bit of the GPIOs when in input mode is not offset by 4 unlike the AXP209.

2017-12-07pinctrl: axp209: add programmable ADC muxing valueQuentin Schulz1-1/+3
To prepare for patches that will add support for a new PMIC that has a different GPIO adc muxing value, add an adc_mux within axp20x_pctl structure and use it.

2017-12-07pinctrl: axp209: rename everything from gpio to pctlQuentin Schulz1-88/+88
This driver used to do only GPIO features of the GPIOs in X-Powers AXP20X. Now that we have migrated everything to the pinctrl subsystem and added pinctrl features, rename everything related to pinctrl from gpio to pctl to ease the understanding of differences between GPIO and pinctrl features.

2017-12-07pinctrl: axp209: add pinctrl featuresQuentin Schulz1-20/+284
The X-Powers AXP209 has 3 GPIOs. GPIO0/1 can each act either as a GPIO, an ADC or a LDO regulator. GPIO2 can only act as a GPIO. This adds the pinctrl features to the driver so GPIO0/1 can be used as ADC or LDO regulator.
