2017-05-17ASoC: atmel-classd: sync regcache when resumingQuentin Schulz1-0/+9
The PM functions used in this driver are the ones defined in sounc/soc/soc-core.c. When suspending (using snd_soc_suspend), the regcache is marked dirty but is never synced on resume. Sync regcache on resume of Atmel ClassD device.

2016-08-08ASoC: codec duplicated callback function goes to component on atmel-classdKuninori Morimoto1-2/+4
codec driver and component driver has duplicated callback functions, and codec side functions are just copied to component side when register timing. This was quick-hack, but no longer needed. This patch moves these functions from codec driver to component driver. Signed-off-by: Kuninori Morimoto <kuninori.morimoto.gx@renesas.com> Signed-off-by: Mark Brown <broonie@kernel.org>
2016-07-04ASoC: Atmel: ClassD: Simplify use of devm_ioremap_resourceAmitoj Kaur Chawla1-5/+0
Remove unneeded error handling on the result of a call to platform_get_resource when the value is passed to devm_ioremap_resource. The Coccinelle semantic patch that makes this change is as follows: // <smpl> @@ expression pdev,res,n,e,e1; expression ret != 0; identifier l; @@ - res = platform_get_resource(pdev, IORESOURCE_MEM, n); ... when != res - if (res == NULL) { ... \(goto l;\|return ret;\) } ... when != res + res = platform_get_resource(pdev, IORESOURCE_MEM, n); e = devm_ioremap_resource(e1, res); // </smpl> Signed-off-by: Amitoj Kaur Chawla <amitoj1606@gmail.com> Signed-off-by: Mark Brown <broonie@kernel.org>
