Add a device tree for A3U and A5U with initial support for: - SDHCI (internal and external storage) - USB Device Mode - UART (on USB connector via the SM5502 MUIC) - Regulators The two devices (and all other variants of A3/A5 released in 2015) are very similar, with some differences in display, touchscreen and sensors. The common parts are shared in msm8916-samsung-a2015-common.dtsi to reduce duplication. The device tree is loosely based on apq8016-sbc.dtsi and the downstream kernel provided by Samsung, mixed with a lot of own research. Co-developed-by: Michael Srba Signed-off-by: Michael Srba Signed-off-by: Stephan Gerhold --- The idea is to leverage the efforts that went into mainline for the Dragonboard 410c. So far this is going quite well. In addition to the functionality provided by this patch, the following features also seem to work in initial tests: - Display/GPU - Touchscreen - Sound (Earpiece and Headphones) - Accelerometer + Magnetometer Those will be added in future patch sets. The primary known limitation is the lack of PSCI support in the signed TrustZone firmware. It seems like all production MSM8916 smartphones were released without PSCI support, and only DB410c was updated. Not sure if there is any good solution for this... arch/arm64/boot/dts/qcom/Makefile | 2 + .../msm8916-samsung-a2015-common-pins.dtsi | 15 ++ .../qcom/msm8916-samsung-a2015-common.dtsi | 226 ++++++++++++++++++ .../boot/dts/qcom/msm8916-samsung-a3u-eur.dts | 10 + .../boot/dts/qcom/msm8916-samsung-a5u-eur.dts | 10 + 5 files changed, 263 insertions(+) create mode 100644 arch/arm64/boot/dts/qcom/msm8916-samsung-a2015-common-pins.dtsi create mode 100644 arch/arm64/boot/dts/qcom/msm8916-samsung-a2015-common.dtsi create mode 100644 arch/arm64/boot/dts/qcom/msm8916-samsung-a3u-eur.dts create mode 100644 arch/arm64/boot/dts/qcom/msm8916-samsung-a5u-eur.dts diff --git a/arch/arm64/boot/dts/qcom/Makefile b/arch/arm64/boot/dts/qcom/Makefile index b3fe72ff2955..d07d9098cccf 100644 --- a/arch/arm64/boot/dts/qcom/Makefile +++ b/arch/arm64/boot/dts/qcom/Makefile @@ -3,6 +3,8 @@ dtb-$(CONFIG_ARCH_QCOM) += apq8016-sbc.dtb dtb-$(CONFIG_ARCH_QCOM) += apq8096-db820c.dtb dtb-$(CONFIG_ARCH_QCOM) += ipq8074-hk01.dtb dtb-$(CONFIG_ARCH_QCOM) += msm8916-mtp.dtb +dtb-$(CONFIG_ARCH_QCOM) += msm8916-samsung-a3u-eur.dtb +dtb-$(CONFIG_ARCH_QCOM) += msm8916-samsung-a5u-eur.dtb dtb-$(CONFIG_ARCH_QCOM) += msm8992-bullhead-rev-101.dtb dtb-$(CONFIG_ARCH_QCOM) += msm8994-angler-rev-101.dtb dtb-$(CONFIG_ARCH_QCOM) += msm8996-mtp.dtb diff --git a/arch/arm64/boot/dts/qcom/msm8916-samsung-a2015-common-pins.dtsi b/arch/arm64/boot/dts/qcom/msm8916-samsung-a2015-common-pins.dtsi new file mode 100644 index 000000000000..58e0d827526d --- /dev/null +++ b/arch/arm64/boot/dts/qcom/msm8916-samsung-a2015-common-pins.dtsi @@ -0,0 +1,15 @@ +// SPDX-License-Identifier: GPL-2.0-only + +&msmgpio { + muic_int_default: muic_int_default { + pinmux { + function = "gpio"; + pins = "gpio12"; + }; + pinconf { + pins = "gpio12"; + drive-strength = <2>; + bias-disable; + }; + }; +}; diff --git a/arch/arm64/boot/dts/qcom/msm8916-samsung-a2015-common.dtsi b/arch/arm64/boot/dts/qcom/msm8916-samsung-a2015-common.dtsi new file mode 100644 index 000000000000..e756b6a39fe9 --- /dev/null +++ b/arch/arm64/boot/dts/qcom/msm8916-samsung-a2015-common.dtsi @@ -0,0 +1,226 @@ +// SPDX-License-Identifier: GPL-2.0-only + +#include "msm8916.dtsi" +#include "pm8916.dtsi" +#include "msm8916-samsung-a2015-common-pins.dtsi" +#include +#include + +/ { + aliases { + serial0 = &blsp1_uart2; + }; + + chosen { + stdout-path = "serial0"; + }; + + soc { + i2c-muic { + compatible = "i2c-gpio"; + sda-gpios = <&msmgpio 105 (GPIO_ACTIVE_HIGH|GPIO_OPEN_DRAIN)>; + scl-gpios = <&msmgpio 106 (GPIO_ACTIVE_HIGH|GPIO_OPEN_DRAIN)>; + + #address-cells = <1>; + #size-cells = <0>; + + muic: sm5502@25 { + compatible = "siliconmitus,sm5502-muic"; + + reg = <0x25>; + interrupt-parent = <&msmgpio>; + interrupts = <12 IRQ_TYPE_EDGE_FALLING>; + + pinctrl-names = "default"; + pinctrl-0 = <&muic_int_default>; + }; + }; + + sdhci@7824000 { + status = "okay"; + + vmmc-supply = <&pm8916_l8>; + vqmmc-supply = <&pm8916_l5>; + + pinctrl-names = "default", "sleep"; + pinctrl-0 = <&sdc1_clk_on &sdc1_cmd_on &sdc1_data_on>; + pinctrl-1 = <&sdc1_clk_off &sdc1_cmd_off &sdc1_data_off>; + }; + + sdhci@7864000 { + status = "okay"; + + vmmc-supply = <&pm8916_l11>; + vqmmc-supply = <&pm8916_l12>; + + pinctrl-names = "default", "sleep"; + pinctrl-0 = <&sdc2_clk_on &sdc2_cmd_on &sdc2_data_on &sdc2_cd_on>; + pinctrl-1 = <&sdc2_clk_off &sdc2_cmd_off &sdc2_data_off &sdc2_cd_off>; + + cd-gpios = <&msmgpio 38 GPIO_ACTIVE_LOW>; + }; + + serial@78b0000 { + status = "okay"; + pinctrl-names = "default", "sleep"; + pinctrl-0 = <&blsp1_uart2_default>; + pinctrl-1 = <&blsp1_uart2_sleep>; + }; + + usb@78d9000 { + status = "okay"; + extcon = <&muic>; + + hnp-disable; + srp-disable; + adp-disable; + + ulpi { + phy { + extcon = <&muic>; + v1p8-supply = <&pm8916_l7>; + v3p3-supply = <&pm8916_l13>; + }; + }; + }; + + /* + * Attempting to enable these devices causes a "synchronous + * external abort".
