phy: qcom-qmp-usb: fix v3 offsets data

2024-03-06T14:53:59+00:00

[ Upstream commit d4c08d8b23b22807c712208cd05cb047e92e7672 ] The MSM8996 platform has registers setup different to the rest of QMP v3 USB platforms. It has PCS region at 0x600 and no PCS_MISC region, while other platforms have PCS region at 0x800 and PCS_MISC at 0x600. This results in the malfunctioning USB host on some of the platforms. The commit f74c35b630d4 ("phy: qcom-qmp-usb: fix register offsets for ipq8074/ipq6018") fixed the issue for IPQ platforms, but missed the SDM845 which has the same register layout. To simplify future platform addition and to make the driver more future proof, rename qmp_usb_offsets_v3 to qmp_usb_offsets_v3_msm8996 (to mark its peculiarity), rename qmp_usb_offsets_ipq8074 to qmp_usb_offsets_v3 and use it for SDM845 platform.

phy: qcom-qmp-usb: fix serdes init sequence for IPQ6018

2024-02-16T18:14:17+00:00

[ Upstream commit 62a5df451ab911421da96655fcc4d1e269ff6e2f ] Commit 23fd679249df ("phy: qcom-qmp: add USB3 PHY support for IPQ6018") noted that IPQ6018 init is identical to IPQ8074. Yet downstream uses separate serdes init sequence for IPQ6018. Since already existing IPQ9574 serdes init sequence is identical, just reuse it and fix failing USB3 mode in IPQ6018.

phy: qcom-qmp-usb: fix register offsets for ipq8074/ipq6018

2024-02-16T18:14:17+00:00

[ Upstream commit f74c35b630d40d414ca6b53f7b1b468dd4abf478 ] Commit 2be22aae6b18 ("phy: qcom-qmp-usb: populate offsets configuration") introduced register offsets to the driver but for ipq8074/ipq6018 they do not match what was in the old style device tree. Example from old ipq6018.dtsi: <0x00078200 0x130>, /* Tx */ <0x00078400 0x200>, /* Rx */ <0x00078800 0x1f8>, /* PCS */ <0x00078600 0x044>; /* PCS misc */ which would translate to: {.., .pcs = 0x800, .pcs_misc = 0x600, .tx = 0x200, .rx = 0x400 } but was translated to: {.., .pcs = 0x600, .tx = 0x200, .rx = 0x400 } So split usb_offsets and fix USB initialization for IPQ8074 and IPQ6018.
