Subject: [PATCH 1/2] ASoC: rockchip: support ACODEC for rk3328
Date: Fri, 21 Dec 2018 00:36:35 +0900 [thread overview]
Message-ID: <20181220153636.5213-1-katsuhiro@katsuster.net> (raw)
This patch adds support for audio CODEC core of rk3328.
Rockchip does not publish detail specification of this core
but driver source code is opened on their GitHub repository.
https://github.com/rockchip-linux/kernel
So I ported this code to linux-next and added some trivial fixes.

+* Rockchip Rk3328 internal codec
+
+Required properties:
+
+- compatible: "rockchip,rk3328-codec"
+- reg: physical base address of the controller and length of memory mapped
+ region.
+- rockchip,grf: the phandle of the syscon node for GRF register.
+- clocks: a list of phandle + clock-specifer pairs, one for each entry in clock-names.
+- clock-names: should be "pclk".
+- spk-depop-time-ms: speak depop time msec.
+
+Example for rk3328 internal codec:
+
+codec: codec@ff410000 {
+ compatible = "rockchip,rk3328-codec";
+ reg = <0x0 0xff410000 0x0 0x1000>;
+ rockchip,grf = <&grf>;
+ clocks = <&cru PCLK_ACODEC>;
+ clock-names = "pclk";
+ spk-depop-time-ms = 100;
+ status = "disabled";
+};
