From 13f3b9fdef6c7d9ad069ae617707e5a10a685074 Mon Sep 17 00:00:00 2001 From: Daniel Baluta Date: Tue, 4 Jun 2019 20:32:57 +0800 Subject: [PATCH] arm64: dts: imx8mm-evk: Enable audio codec wm8524 i.MX8MM has one wm8524 audio codec connected with SAI3 digital audio interface. This patch uses simple-card machine driver in order to enable wm8524 codec. We need to set: * SAI3 pinctrl configuration * codec reset gpio pinctrl configuration * clock hierarchy * codec node * simple-card configuration Signed-off-by: Daniel Baluta Reviewed-by: Fabio Estevam Signed-off-by: Shawn Guo --- arch/arm64/boot/dts/freescale/imx8mm-evk.dts | 55 ++++++++++++++++++++++++++++ 1 file changed, 55 insertions(+) diff --git a/arch/arm64/boot/dts/freescale/imx8mm-evk.dts b/arch/arm64/boot/dts/freescale/imx8mm-evk.dts index 594f158..ee7f2b2 100644 --- a/arch/arm64/boot/dts/freescale/imx8mm-evk.dts +++ b/arch/arm64/boot/dts/freescale/imx8mm-evk.dts @@ -37,6 +37,37 @@ gpio = <&gpio2 19 GPIO_ACTIVE_HIGH>; enable-active-high; }; + + wm8524: audio-codec { + #sound-dai-cells = <0>; + compatible = "wlf,wm8524"; + pinctrl-names = "default"; + pinctrl-0 = <&pinctrl_gpio_wlf>; + wlf,mute-gpios = <&gpio5 21 GPIO_ACTIVE_LOW>; + }; + + sound-wm8524 { + compatible = "simple-audio-card"; + simple-audio-card,name = "wm8524-audio"; + simple-audio-card,format = "i2s"; + simple-audio-card,frame-master = <&cpudai>; + simple-audio-card,bitclock-master = <&cpudai>; + simple-audio-card,widgets = + "Line", "Left Line Out Jack", + "Line", "Right Line Out Jack"; + simple-audio-card,routing = + "Left Line Out Jack", "LINEVOUTL", + "Right Line Out Jack", "LINEVOUTR"; + + cpudai: simple-audio-card,cpu { + sound-dai = <&sai3>; + }; + + simple-audio-card,codec { + sound-dai = <&wm8524>; + clocks = <&clk IMX8MM_CLK_SAI3_ROOT>; + }; + }; }; &A53_0 { @@ -65,6 +96,15 @@ }; }; +&sai3 { + pinctrl-names = "default"; + pinctrl-0 = <&pinctrl_sai3>; + assigned-clocks = <&clk IMX8MM_CLK_SAI3>; + assigned-clock-parents = <&clk IMX8MM_AUDIO_PLL1_OUT>; + assigned-clock-rates = <24576000>; + status = "okay"; +}; + &snvs_pwrkey { status = "okay"; }; @@ -246,6 +286,12 @@ >; }; + pinctrl_gpio_wlf: gpiowlfgrp { + fsl,pins = < + MX8MM_IOMUXC_I2C4_SDA_GPIO5_IO21 0xd6 + >; + }; + pinctrl_i2c1: i2c1grp { fsl,pins = < MX8MM_IOMUXC_I2C1_SCL_I2C1_SCL 0x400001c3 @@ -265,6 +311,15 @@ >; }; + pinctrl_sai3: sai3grp { + fsl,pins = < + MX8MM_IOMUXC_SAI3_TXFS_SAI3_TX_SYNC 0xd6 + MX8MM_IOMUXC_SAI3_TXC_SAI3_TX_BCLK 0xd6 + MX8MM_IOMUXC_SAI3_MCLK_SAI3_MCLK 0xd6 + MX8MM_IOMUXC_SAI3_TXD_SAI3_TX_DATA0 0xd6 + >; + }; + pinctrl_uart2: uart2grp { fsl,pins = < MX8MM_IOMUXC_UART2_RXD_UART2_DCE_RX 0x140 -- 2.7.4
