[ Upstream commit 399c91c3f30531593e5ff6ca7b53f47092128669 ] The of_device_get_match_data() function may return NULL. Add check to prevent potential null dereference.

phy: cadence: Sierra: Fix to get correct parent for mux clocks

[ Upstream commit da08aab940092a050a4fb2857ed9479d2b0e03c4 ] Fix get_parent() callback to return the correct index of the parent for PLL_CMNLC1 clock. Add a separate table of register values corresponding to the parent index for PLL_CMNLC1. Update set_parent() callback accordingly.

phy: Sparx5 Eth SerDes: Fix return value check in sparx5_serdes_probe()

[ Upstream commit b4dc97ab0a629eda8bda20d96ef47dac08a505d9 ] In case of error, the function devm_ioremap() returns NULL pointer not ERR_PTR(). The IS_ERR() test in the return value check should be replaced with NULL test.

phy: qcom-snps: Correct the FSEL_MASK

2021-11-18T18:16:56Z

[ Upstream commit b475bf0ec40a2b13fb32ef62f5706576d5858460 ] The FSEL_MASK which selects the refclock is defined incorrectly. It should be [4:6] not [5:7]. Due to this incorrect definition, the BIT(7) in USB2_PHY_USB_PHY_HS_PHY_CTRL_COMMON0 is reset which keeps PHY analog blocks ON during suspend. Fix this issue by correctly defining the FSEL_MASK.

phy: qcom-qmp: another fix for the sc8180x PCIe definition

2021-11-18T18:16:56Z

[ Upstream commit 26f71abef580537d978f6299330689f029ee1e6c ] Commit f839f14e24f2 ("phy: qcom-qmp: Add sc8180x PCIe support") added SC8180X PCIe tables, but used sm8250_qmp_pcie_serdes_tbl as a serdes table because of the copy paste error. Commit bfccd9a71a08 ("phy: qcom-qmp: Fix sc8180x PCIe definition") corrected part of this mistake by pointing serdes_tbl to sc8180x_qmp_pcie_serdes_tbl, however the serdes_tbl_num field was not updated to use sc8180x table. So let's now fix the serdes_tbl_num field too.
