Changes since v1: ----------------- - v1 can be found here: https://lore.kernel.org/linux-arm-msm/20220223192946.473172-1-bhupesh.sharma@linaro.org/T/ - Collected ACKs on [PATCH 1/7], [PATCH 2/7] and [PATCH 4/7] from Rob and Dmitry. - Broke down another separately sent out PATCH (see [1]), into a 3 patches (one each for emac, pci and ufs gdsc defines) - one of which is carried as [PATCH 3/7] in this series, which fixes a compilation error. The rest of the gdsc defines have been sent out as separate patch(es). [1]. https://patchwork.kernel.org/project/netdevbpf/patch/20220126221725.710167-4-bhupesh.sharma@linaro.org/ - Rob's bot reported a number of 'dtbs_check' errors with the v1 series, which are been fixed with a separate series now (see [2]), to ease the review of this series. [2]. https://lore.kernel.org/linux-arm-msm/20220228123019.382037-1-bhupesh.sharma@linaro.org/T/ This series adds PCIe support for Qualcomm SM8150 SoC with relevant PHYs. There are 2 PCIe instances on this SoC each with different PHYs. The PCIe controller and PHYs are mostly compatible with the ones found on SM8250 SoC, hence the old drivers are modified to add the support. This series has been tested on SA8155p ADP board with QCA6696 chipset connected onboard.
