2022-07-05phy: ti: tusb1210: Don't check for write errors when powering onAndy Shevchenko
On some platforms, like Intel Merrifield, the writing values during power on may timeout: tusb1210 dwc3.0.auto.ulpi: error -110 writing val 0x41 to reg 0x80 phy phy-dwc3.0.auto.ulpi.0: phy poweron failed --> -110 dwc3 dwc3.0.auto: error -ETIMEDOUT: failed to initialize core dwc3: probe of dwc3.0.auto failed with error -110 which effectively fails the probe of the USB controller.

For exynos auto v9's UFS MPHY, We should use 0x50 offset of TSRV register configurations. So, it must be s/PHY_TRSV_REG_CFG/PHY_TRSV_REG_CFG_AUTOV9/g Fixes: d64519249e1d ("phy: samsung-ufs: support exynosauto ufs phy driver") Signed-off-by: Chanho Park <chanho61.park@samsung.com> Acked-by: Krzysztof Kozlowski <krzysztof.kozlowski@linaro.org> Link: https://lore.kernel.org/r/20220603050536.61957-1-chanho61.park@samsung.com Signed-off-by: Vinod Koul <vkoul@kernel.org>
2022-06-08phy: samsung: ufs: support secondary ufs phyChanho Park
To support secondary ufs phy device, we need to get an offset for phy isolation from the syscon DT node. If the first index argument of the node is existing, we can read the offset value and set it as isol->offset.

2022-06-08phy: samsung: ufs: remove drvdata from struct samsung_ufs_phyChanho Park
To change an offset of pmu_isol, we need to store its data instead of having drvdata's pointer. The definition of the pmu_isol structure should be extracted from samsung_ufs_phy_drvdata and rename the name with samsung_ufs_phy_ prefix.

Make sure to disable the pipe clock also if ufs-reset deassertion fails during power on. Note that the ufs-reset is asserted in qcom_qmp_phy_com_exit().

2022-05-03phy: qcom-qmp: switch to explicit reset helpersJohan Hovold
Switch to consistently using the explicit reset-controller API which makes it clear that the reset controllers are used exclusively by the PHY driver. Note that the deprecated of_reset_control_get() and devm_reset_control_get() are just transitional wrappers for the explicit API so there's no functional change.

Make sure to release the lane reset controller in case of a late probe error (e.g. probe deferral). Note that due to the reset controller being defined in devicetree in "lane" child nodes, devm_reset_control_get_exclusive() cannot be used directly.
