Date: Tue, 6 Oct 2015 16:06:55 +0900 From: Jiada Wang <jiada_wang@...tor.com> To: <lgirdwood@...il.com>, <broonie@...nel.org>, <perex@...ex.cz>, <tiwai@...e.com>, <patches@...nsource.wolfsonmicro.com>, <alsa-devel@...a-project.org>, <linux-kernel@...r.kernel.org> CC: <jiada_wang@...tor.com> Subject: [PATCH 2/2] ASoC: Codec: wm8962: declare ALC Coefficients as 4 separate registers As ALC2 register is volatile, declare it as one of ALC Coefficients register together with other non-volatile registers will cause issue, in case wm8962 has enter suspend mode, and cache_only flag is set, any attempt to read from ALC2 will fail. Instead of declaring one ALC Coefficients register which contains ALC1 ~ ALC3 and Noise Gate, this patch declares 4 separate registers, so that regmap can handle these registers differently based on their classification.
