phy: qcom-qmp: drop old QMP PHY driver source

2022-06-09T18:19:41+00:00

As we have switched to the new (split) QMP PHY driver, drop the old monolithic QMP driver source.

phy: qcom-qmp: rename error labels

2022-05-03T04:42:03+00:00

Rename all error labels after what they are used for in order to improve readability and for consistency. Signed-off-by: Johan Hovold Link: https://lore.kernel.org/r/20220502133130.4125-3-johan+linaro@kernel.org Signed-off-by: Vinod Koul

phy: qcom-qmp: fix pipe-clock imbalance on power-on failure

2022-05-03T04:42:03+00:00

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().

phy: qcom-qmp: switch to explicit reset helpers

2022-05-03T04:41:01+00:00

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.

phy: qcom-qmp: fix reset-controller leak on probe errors

2022-05-03T04:41:01+00:00

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.
