Note: The original firmware from Acer can only boot 32-bit kernels. To boot arm64 kernels it is necessary to flash 64-bit TZ/HYP firmware with EDL, e.g. taken from the DragonBoard 410c. This works because Acer didn't set up (firmware) secure boot. Add a device tree for with initial support for: - GPIO keys - pm8916-vibrator - SDHCI (internal and external storage) - USB Device Mode - UART - WCNSS (WiFi/BT) - Regulators Signed-off-by: Lin, Meng-Bo Reviewed-by: Konrad Dybcio --- arch/arm64/boot/dts/qcom/Makefile | 1 + .../boot/dts/qcom/msm8916-acer-a1-724.dts | 217 ++++++++++++++++++ 2 files changed, 218 insertions(+) create mode 100644 arch/arm64/boot/dts/qcom/msm8916-acer-a1-724.dts diff --git a/arch/arm64/boot/dts/qcom/Makefile b/arch/arm64/boot/dts/qcom/Makefile index afe496a93f94..f38a20074013 100644 --- a/arch/arm64/boot/dts/qcom/Makefile +++ b/arch/arm64/boot/dts/qcom/Makefile @@ -7,6 +7,7 @@ dtb-$(CONFIG_ARCH_QCOM) += ipq6018-cp01-c1.dtb dtb-$(CONFIG_ARCH_QCOM) += ipq8074-hk01.dtb dtb-$(CONFIG_ARCH_QCOM) += ipq8074-hk10-c1.dtb dtb-$(CONFIG_ARCH_QCOM) += ipq8074-hk10-c2.dtb +dtb-$(CONFIG_ARCH_QCOM) += msm8916-acer-a1-724.dtb dtb-$(CONFIG_ARCH_QCOM) += msm8916-alcatel-idol347.dtb dtb-$(CONFIG_ARCH_QCOM) += msm8916-asus-z00l.dtb dtb-$(CONFIG_ARCH_QCOM) += msm8916-huawei-g7.dtb diff --git a/arch/arm64/boot/dts/qcom/msm8916-acer-a1-724.dts b/arch/arm64/boot/dts/qcom/msm8916-acer-a1-724.dts new file mode 100644 index 000000000000..593051ea92b6 --- /dev/null +++ b/arch/arm64/boot/dts/qcom/msm8916-acer-a1-724.dts @@ -0,0 +1,217 @@ +// SPDX-License-Identifier: GPL-2.0-only + +/dts-v1/;
