Subject: [PATCH v2 0/2] arm64: dts: qcom: Add Qualcomm RB2 board dts
Date: Thu, 16 Mar 2023 02:31:43 +0530 [thread overview]
Message-ID: <20230315210145.2221116-1-bhupesh.sharma@linaro.org> (raw)
Changes since v1:
-----------------
- v1 can be viewed here: https://lore.kernel.org/linux-arm-msm/20230314210828.2049720-1-bhupesh.sharma@linaro.org/
- Addressed review comments from Konrad and fixed the board dts and also
added a new 'qcom,qrb4210' compatible.
- Although Krzysztof provided an Ack for [PATCH 1/2] from the v1 series,
since this series introduces the new 'qcom,qrb4210' compatible, so I
have dropped the same for now.
Add an initial device tree for Qualcomm RB2 board (see [1]).
It is based on the Robotics version of the Snapdragon SM4250
Soc, i.e. QRB4210.
Currently it enables:
- eMMC via SDHC1,
- uSD card via SDHC2,
- RPM regulators,
- Debug UART (via micro USB port).
Subsequent patchset(s) will add more peripherals like USB, etc.
This patchset is dependent on the QRB4210 SocInfo patchset sent out
earlier (see [2]).
To get a successful boot run:
$ cat arch/arm64/boot/Image.gz arch/arm64/boot/dts/qcom/\
qrb4210-rb2.dtb > ./Image-adp.gz+dtb
$ mkbootimg --kernel ./Image-adp.gz+dtb \
--ramdisk ./some-initramfs-image.rootfs.img \
--output ./rb2-boot.img --pagesize 4096 \
--base 0x80000000 --cmdline 'SOME_CMDLINE'
$ fastboot boot ./rb2-boot.img
