From b03109c094e63911ee913afc91f715895c5917d8 Mon Sep 17 00:00:00 2001 From: Sander Vanheule Date: Tue, 7 Jun 2022 08:42:05 +0200 Subject: [PATCH] realtek: add mux pinctrl for rtl931x Add a pinctrl-single node to manage the sys-led mux and JTAG mux. This allows using the associated pins as GPIOs: - sys-led: GPIO0 - JTAG: GPIO6, GPIO7, others unknown (TDO, TDI, TMS, TCK /TRST) Suggested-by: Birger Koblitz Signed-off-by: Sander Vanheule --- target/linux/realtek/dts-5.10/rtl931x.dtsi | 19 +++++++++++++++++++ 1 file changed, 19 insertions(+) diff --git a/target/linux/realtek/dts-5.10/rtl931x.dtsi b/target/linux/realtek/dts-5.10/rtl931x.dtsi index 29aee1f7b2..a5166141e6 100644 --- a/target/linux/realtek/dts-5.10/rtl931x.dtsi +++ b/target/linux/realtek/dts-5.10/rtl931x.dtsi @@ -155,6 +155,25 @@ }; }; + pinmux: pinmux@1b001358 { + compatible = "pinctrl-single"; + reg = <0x1b001358 0x4>; + + pinctrl-single,bit-per-mux; + pinctrl-single,register-width = <32>; + pinctrl-single,function-mask = <0x1>; + #pinctrl-cells = <2>; + + /* Enable GPIO6 and GPIO7, possibly unknown others */ + pinmux_disable_jtag: disable_jtag { + pinctrl-single,bits = <0x0 0x0 0x8000>; + }; + + /* Controls GPIO0 */ + pinmux_disable_sys_led: disable_sys_led { + pinctrl-single,bits = <0x0 0x0 0x100>; + }; + }; ethernet0: ethernet@1b00a300 { status = "okay"; -- 2.30.2
