ASoC: codec: Convert to GPIO descriptors for
Merge series from Peng Fan <peng.fan@nxp.com>: This patchset is a pick up of patch 1,2 from [1]. And I also collect Linus's R-b for patch 2. After this patchset, there is only one user of of_gpio.h left in sound driver(pxa2xx-ac97). of_gpio.h is deprecated, update the driver to use GPIO descriptors. Patch 1 is to drop legacy platform data which in-tree no users are using it Patch 2 is to convert to GPIO descriptors Checking the DTS that use the device, all are using GPIOD_ACTIVE_LOW polarity for reset-gpios, so all should work as expected with this patch.
