From 2943660fe301aa650cdf60226a2a350d09145823 Mon Sep 17 00:00:00 2001 From: Peter Geis Date: Thu, 27 Jan 2022 19:38:08 -0500 Subject: [PATCH] arm64: dts: rockchip: add Quartz64-A con40 hardware The Quartz64-A has a 40 pin connector that exposes various functions. Annotate the functions exposed in the device tree. Enable i2c3, which is pulled up to vcc_3v3 on board. The following functions are currently exposed: i2c3 spi1 uart2 uart0 spdif Signed-off-by: Peter Geis Link: https://lore.kernel.org/r/20220128003809.3291407-5-pgwipeout@gmail.com Signed-off-by: Heiko Stuebner --- .../boot/dts/rockchip/rk3566-quartz64-a.dts | 23 +++++++++++++++++++ 1 file changed, 23 insertions(+) diff --git a/arch/arm64/boot/dts/rockchip/rk3566-quartz64-a.dts b/arch/arm64/boot/dts/rockchip/rk3566-quartz64-a.dts index 94a164d6bce94..8332627f483b1 100644 --- a/arch/arm64/boot/dts/rockchip/rk3566-quartz64-a.dts +++ b/arch/arm64/boot/dts/rockchip/rk3566-quartz64-a.dts @@ -467,6 +467,14 @@ }; }; +/* i2c3 is exposed on con40 + * pin 3 - i2c3_sda_m0, pullup to vcc_3v3 + * pin 5 - i2c3_scl_m0, pullup to vcc_3v3 + */ +&i2c3 { + status = "okay"; +}; + &i2s1_8ch { pinctrl-names = "default"; pinctrl-0 = <&i2s1m0_sclktx @@ -583,10 +591,17 @@ status = "okay"; }; +/* spdif is exposed on con40 pin 18 */ &spdif { status = "okay"; }; +/* spi1 is exposed on con40 + * pin 11 - spi1_mosi_m1 + * pin 13 - spi1_miso_m1 + * pin 15 - spi1_clk_m1 + * pin 17 - spi1_cs0_m1 + */ &spi1 { pinctrl-names = "default"; pinctrl-0 = <&spi1m1_cs0 &spi1m1_pins>; @@ -600,6 +615,10 @@ status = "okay"; }; +/* uart0 is exposed on con40 + * pin 12 - uart0_tx + * pin 14 - uart0_rx + */ &uart0 { pinctrl-names = "default"; pinctrl-0 = <&uart0_xfer>; @@ -626,6 +645,10 @@ }; }; +/* uart2 is exposed on con40 + * pin 8 - uart2_tx_m0_debug + * pin 10 - uart2_rx_m0_debug + */ &uart2 { status = "okay"; }; -- 2.30.2
