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]).
