The ACSPCIE_PROXY_CTRL registers within the CTRL_MMR space of TI's J784S4 SoC are used to drive the reference clock to the PCIe Endpoint device via the PAD IO Buffers. Add the compatible for allowing the PCIe driver to obtain the regmap for the ACSPCIE_CTRL register within the System Controller device-tree node in order to enable the PAD IO Buffers. The Technical Reference Manual for J784S4 SoC with details of the ASCPCIE_CTRL registers is available at: https://www.ti.com/lit/zip/spruj52 Signed-off-by: Siddharth Vadapalli <s-vadapalli@xxxxxx> Acked-by: Krzysztof Kozlowski <krzysztof.kozlowski@xxxxxxxxxx> --- Hello, This patch is based on linux-next tagged next-20240729. v1: https://lore.kernel.org/r/20240715120936.1150314-2-s-vadapalli@xxxxxx/ Changes since v1: - Rebased patch on next-20240729. - Separated this patch from the series. - Collected Acked-by tag from: Krzysztof Kozlowski <krzysztof.kozlowski@xxxxxxxxxx> https://lore.kernel.org/r/04d94188-5e30-4cab-b534-e97c0b2a61f3@xxxxxxxxxx/ NOTE: Though it was mentioned on 25th July 2024 that this patch was applied: https://lore.kernel.org/r/172190301400.925833.12525656543896105526.b4-ty@xxxxxxxxxx/ since I did not find the commit in the MFD tree and the Linux-Next tree, I am reposting this patch.
