Subject: [PATCH v2 1/4] Documentation: dt-bindings: add the Amlogic Meson SAR ADC documentation
Date: Sun, 15 Jan 2017 23:42:18 +0100 [thread overview]
Message-ID: <20170115224221.15510-2-martin.blumenstingl@googlemail.com> (raw)
In-Reply-To: <20170115224221.15510-1-martin.blumenstingl@googlemail.com>
This adds the devicetree binding documentation for the SAR ADC found in
Amlogic Meson SoCs.
Currently only the GXBB, GXL and GXM SoCs are supported.

+* Amlogic Meson SAR (Successive Approximation Register) A/D converter
+
+Required properties:
+- compatible: depending on the SoC this should be one of:
+ - "amlogic,meson-gxbb-saradc" for GXBB
+ - "amlogic,meson-gxl-saradc" for GXL and GXM
+ along with the generic "amlogic,meson-saradc"
+- reg: the physical base address and length of the registers
+- clocks: phandle and clock identifier (see clock-names)
+- clock-names: mandatory clocks:
+ - "clkin" for the reference clock (typically XTAL)
+ - "core" for the SAR ADC core clock
+ optional clocks:
+ - "sana" for the analog clock
+ - "adc_clk" for the ADC (sampling) clock
+ - "adc_sel" for the ADC (sampling) clock mux
+- vref-supply: the regulator supply for the ADC reference voltage
+- #io-channel-cells: must be 1, see ../iio-bindings.txt
+
+Example:
+ saradc: adc@8680 {
+ compatible = "amlogic,meson-gxl-saradc", "amlogic,meson-saradc";
+ #io-channel-cells = <1>;
+ reg = <0x0 0x8680 0x0 0x34>;
+ clocks = <&xtal>,
+ <&clkc CLKID_SAR_ADC>,
+ <&clkc CLKID_SANA>,
+ <&clkc CLKID_SAR_ADC_CLK>,
+ <&clkc CLKID_SAR_ADC_SEL>;
+ clock-names = "clkin", "core", "sana", "adc_clk", "adc_sel";
+ };
