phy: qcom-qmp-pcie-msm8996: fix init-count imbalance

2023-06-09T08:48:18+00:00

commit e42f110700ed7293700c26145e1ed07ea05ac3f6 upstream.

The init counter is not decremented on initialisation errors, which
prevents retrying initialisation.

Add the missing decrement on initialisation errors so that the counter
reflects the state of the device.

phy: qcom-qmp-combo: fix init-count imbalance

2023-06-09T08:48:18+00:00

commit 9bf03a0cbd80a256bc1e1c4bcc80bc2b06b8b2b9 upstream.

The init counter is not decremented on initialisation errors, which
prevents retrying initialisation and can lead to the runtime suspend
callback attempting to disable resources that have never been enabled.

Add the missing decrement on initialisation errors so that the counter
reflects the state of the device.

phy: qcom-qmp-pcie: sc8180x PCIe PHY has 2 lanes

2023-05-11T14:16:47+00:00

commit 1db6b0a4246ce708b89f5136571130b9987741d1 upstream.

All PCIe PHYs on sc8180x platform have 2 lanes, so change the number of
lanes to 2.

phy: qcom: phy-qcom-snps-eusb2: Add support for eUSB2 repeater

2023-02-16T13:10:27+00:00

For USB 2.0 compliance, eUSB2 needs a repeater. The PHY needs to
initialize and reset it. So add repeater support

phy: qcom: Add QCOM SNPS eUSB2 repeater driver

2023-02-16T13:10:27+00:00

PM8550B contains a eUSB2 repeater used for making the eUSB2 from
SM8550 USB 2.0 compliant. This can be modelled SW-wise as a Phy.
So add a new phy driver for it.
