From 8cf890aabd45664b8f27a5581c8d2a51a8ce2e17 Mon Sep 17 00:00:00 2001 From: Shengyu Qu Date: Sun, 30 Oct 2022 01:09:08 +0800 Subject: [PATCH] arm64: dts: rockchip: Add nodes for SDIO/UART Wi-Fi/Bluetooth modules to Radxa Rock 3A This patch adds related bus/pinctrl/power nodes to enable support for Radxa's Wi-Fi Bluetooth combo module. Tested with RADXA A6 module, which uses AP6275S (BCM43752A2) Signed-off-by: Shengyu Qu Link: https://lore.kernel.org/r/OS3P286MB25972313C916A68698B1CD8698359@OS3P286MB2597.JPNP286.PROD.OUTLOOK.COM Signed-off-by: Heiko Stuebner --- .../boot/dts/rockchip/rk3568-rock-3a.dts | 69 +++++++++++++++++++ 1 file changed, 69 insertions(+) diff --git a/arch/arm64/boot/dts/rockchip/rk3568-rock-3a.dts b/arch/arm64/boot/dts/rockchip/rk3568-rock-3a.dts index c932ca4d476cd..ef9b49003ca50 100644 --- a/arch/arm64/boot/dts/rockchip/rk3568-rock-3a.dts +++ b/arch/arm64/boot/dts/rockchip/rk3568-rock-3a.dts @@ -60,6 +60,17 @@ }; }; + sdio_pwrseq: sdio-pwrseq { + compatible = "mmc-pwrseq-simple"; + clocks = <&rk809 1>; + clock-names = "ext_clock"; + pinctrl-names = "default"; + pinctrl-0 = <&wifi_enable>; + post-power-on-delay-ms = <100>; + power-off-delay-us = <5000000>; + reset-gpios = <&gpio3 RK_PD4 GPIO_ACTIVE_LOW>; + }; + vcc12v_dcin: vcc12v-dcin-regulator { compatible = "regulator-fixed"; regulator-name = "vcc12v_dcin"; @@ -654,6 +665,26 @@ rockchip,pins = <0 RK_PA5 RK_FUNC_GPIO &pcfg_pull_none>; }; }; + + bt { + bt_enable: bt-enable { + rockchip,pins = <4 RK_PB2 RK_FUNC_GPIO &pcfg_pull_none>; + }; + + bt_host_wake: bt-host-wake { + rockchip,pins = <4 RK_PB4 RK_FUNC_GPIO &pcfg_pull_down>; + }; + + bt_wake: bt-wake { + rockchip,pins = <4 RK_PB5 RK_FUNC_GPIO &pcfg_pull_none>; + }; + }; + + sdio-pwrseq { + wifi_enable: wifi-enable { + rockchip,pins = <3 RK_PD4 RK_FUNC_GPIO &pcfg_pull_none>; + }; + }; }; &pmu_io_domains { @@ -698,12 +729,50 @@ status = "okay"; }; +&sdmmc2 { + supports-sdio; + bus-width = <4>; + disable-wp; + cap-sd-highspeed; + cap-sdio-irq; + keep-power-in-suspend; + mmc-pwrseq = <&sdio_pwrseq>; + non-removable; + pinctrl-names = "default"; + pinctrl-0 = <&sdmmc2m0_bus4 &sdmmc2m0_cmd &sdmmc2m0_clk>; + sd-uhs-sdr104; + vmmc-supply = <&vcc3v3_sys>; + vqmmc-supply = <&vcc_1v8>; + status = "okay"; +}; + &tsadc { rockchip,hw-tshut-mode = <1>; rockchip,hw-tshut-polarity = <0>; status = "okay"; }; +&uart1 { + pinctrl-names = "default"; + pinctrl-0 = <&uart1m0_xfer &uart1m0_ctsn &uart1m0_rtsn>; + uart-has-rtscts; + status = "okay"; + + bluetooth { + compatible = "brcm,bcm43438-bt"; + clocks = <&rk809 1>; + clock-names = "lpo"; + device-wakeup-gpios = <&gpio4 RK_PB5 GPIO_ACTIVE_HIGH>; + host-wakeup-gpios = <&gpio4 RK_PB4 GPIO_ACTIVE_HIGH>; + shutdown-gpios = <&gpio4 RK_PB2 GPIO_ACTIVE_HIGH>; + pinctrl-names = "default"; + pinctrl-0 = <&bt_host_wake &bt_wake &bt_enable>; + vbat-supply = <&vcc3v3_sys>; + vddio-supply = <&vcc_1v8>; + /* vddio comes from regulator on module, use IO bank voltage instead */ + }; +}; + &uart2 { status = "okay"; }; -- 2.30.2
