Subject: [PATCH 1/2] dt-bindings: clock: add description of 74aup1g157gw
Date: Wed, 10 Oct 2018 02:16:35 +0000 [thread overview]
Message-ID: <87d0si1rkt.wl-kuninori.morimoto.gx@renesas.com> (raw)
In-Reply-To: <87efcy1rm4.wl-kuninori.morimoto.gx@renesas.com>
From: Kuninori Morimoto <kuninori.morimoto.gx@renesas.com>
74aup1g157gw needs i0 and i1 pin as input, select and output it by
sel gpio pin. This patch adds description for 74aup1g157gw as clock
multiplexer.
"nxp,74aup1g157gw-clk" will select most closest input as output,
"nxp,74aup1g157gw-audio-clk" will select 48kHz/44.1kHz categorized
input as output.

+NXP 74AUP1G157GW Low-power 2-input multiplexer for clock
+
+Required properties:
+- compatible: "nxp,74aup1g157gw-clk" (select closest input as output)
+ "nxp,74aup1g157gw-audio-clk (select 48kHz / 44.1kHz as output)
+- clocks: select input clock as i0, i1
+- clock-names: "i0" and "i1"
+- sel-gpios: selector pin

+Examples:
+
+ clk {
+ #clock-cells = <0>;
+ compatible = "nxp,74aup1g157gw-audio-clk";
+ clocks = <&clk8snd>, <&clksnd>;
+ clock-names = "i0", "i1";
+ sel-gpios = <&gpio_exp_75 13 GPIO_ACTIVE_HIGH>;
