From c695abab2429cfa9554aa353702936d1f064f073 Mon Sep 17 00:00:00 2001 From: Sylwester Nawrocki Date: Wed, 10 Aug 2016 16:48:20 +0200 Subject: mfd: Add Samsung Exynos Low Power Audio Subsystem driver This patch adds common driver for the Top block of the Samsung Exynos SoC Low Power Audio Subsystem. This is a minimal driver which prepares resources for IP blocks like I2S, audio DMA and UART and exposes a regmap for the Top block registers. Also system power ops are added to ensure the Audio Subsystem is operational after system suspend/resume cycle.
