* mfd: wcd934x: Replace legacy gpio interface for gpiodMaíra Canal2021-11-051-12/+9
| | | | | | | | | | Considering the current transition of the GPIO subsystem, remove all dependencies of the legacy GPIO interface (linux/gpio.h and linux /of_gpio.h) and replace it with the descriptor-based GPIO approach.

* mfd: wcd934x: Add macro for adding new interruptsSrinivas Kandagatla2021-06-021-26/+17
| | | | | | | | | | | | | | | | | | Currently only two interrupts supported is added in wcd934x interrupt controller, however if we are adding more interrupts the file will become too much unreadable. So add a macro to make adding new interrupts easy and also convert existing slim and soundwire interrupts to use it. This is in preparation to enable Multi Button Headset Control support on this codec. WCD934x supports Multi Button Headset control which enable headset detection along with headset button detection. This patch adds interrupts required for MBHC functionality. Signed-off-by: Srinivas Kandagatla <srinivas.kandagatla@linaro.org> Signed-off-by: Lee Jones <lee.jones@linaro.org>
* mfd: wcd934x: Simplify with dev_err_probe()Krzysztof Kozlowski2020-09-301-6/+3
| | | | | | | | Common pattern of handling deferred probe can be simplified with dev_err_probe(). Less code and also it prints the error value. Signed-off-by: Krzysztof Kozlowski <krzk@kernel.org> Signed-off-by: Lee Jones <lee.jones@linaro.org>
* mfd: wcd934x: Drop kfree for memory allocated with devm_kzallocWei Yongjun2020-05-261-1/+0
| | | | | | | | | It's not necessary to free memory allocated with devm_kzalloc and using kfree leads to a double free. Fixes: 6ac7e4d7ad70 ("mfd: wcd934x: Add support to wcd9340/wcd9341 codec") Signed-off-by: Wei Yongjun <weiyongjun1@huawei.com> Signed-off-by: Lee Jones <lee.jones@linaro.org>
