From c821b81bbc00822a164de0c2fdb8cafacd487b26 Mon Sep 17 00:00:00 2001 From: Martin Blumenstingl Date: Sat, 22 Sep 2018 17:10:01 +0200 Subject: ARM: dts: meson8b: add the I2C_A, PWM_C and UART_B pins These are used for example on the Endless Mini (EC-100): - I2C_A is connected to the Realtek RT5640 audio codec - PWM_C (GPIODV_9) is connected to a PWM regulator which is used for VCCK (CPU voltage supply) - UART_B is connected to the Bluetooth module (of the RTL8723BS SDIO wifi and Bluetooth combo chip) Signed-off-by: Martin Blumenstingl Signed-off-by: Kevin Hilman --- arch/arm/boot/dts/meson8b.dtsi | 30 ++++++++++++++++++++++++++++++ 1 file changed, 30 insertions(+) (limited to 'arch/arm/boot/dts/meson8b.dtsi') diff --git a/arch/arm/boot/dts/meson8b.dtsi b/arch/arm/boot/dts/meson8b.dtsi index f77e419c1c65..4bbbbc6bea83 100644 --- a/arch/arm/boot/dts/meson8b.dtsi +++ b/arch/arm/boot/dts/meson8b.dtsi @@ -223,6 +223,13 @@ }; }; + i2c_a_pins: i2c-a { + mux { + groups = "i2c_sda_a", "i2c_sck_a"; + function = "i2c_a"; + }; + }; + sd_b_pins: sd-b { mux { groups = "sd_d0_b", "sd_d1_b", "sd_d2_b", @@ -230,6 +237,29 @@ function = "sd_b"; }; }; + + pwm_c1_pins: pwm-c1 { + mux { + groups = "pwm_c1"; + function = "pwm_c"; + }; + }; + + uart_b0_pins: uart-b0 { + mux { + groups = "uart_tx_b0", + "uart_rx_b0"; + function = "uart_b"; + }; + }; + + uart_b0_cts_rts_pins: uart-b0-cts-rts { + mux { + groups = "uart_cts_b0", + "uart_rts_b0"; + function = "uart_b"; + }; + }; }; }; -- cgit
