2018-05-22ASoC: codec: wolfson: Make the node name genericFabio Estevam
According to Devicetree Specification v0.2 document: "The name of a node should be somewhat generic, reflecting the function of the device and not its precise programming model." Do as suggested in the bindings examples. Signed-off-by: Fabio Estevam <fabio.estevam@nxp.com> Signed-off-by: Mark Brown <broonie@kernel.org>
2017-03-20ASoC: wm8903: add regulator handlingLinus Walleij
The WM8903 has four different voltage inputs: AVDD, CPVDD, DBVDD and DCVDD. On the Qualcomm APQ8060 Dragonboard these are all supplied from proper regulators and thus need activating and binding. This is a quick-and-dirty solution just grabbing and enabling the regulator supplies on probe() and disabling them on remove() and the errorpath. More elaborate power management is likely possible. I assume the nVidia designs using this codec have some hard-wired always-on power and will be happy with using the dummy regulators for this. But someone from the nVidia camp should probably check whether they can bind these to proper regulators instead. We also amend the DT binding document. A small change like this does not warrant a separate patch for augmenting these.

2011-12-06ASoC: WM8903: Add device tree bindingStephen Warren
Document the device tree binding for the WM8903 codec, and modify the driver to extract platform data from the device tree, if present. Based on work by John Bonesio, but significantly reworked since then. Signed-off-by: Stephen Warren <swarren@nvidia.com> Signed-off-by: Mark Brown <broonie@opensource.wolfsonmicro.com>
