Bjorn Andersson 42020c7065 phy: qcom-ufs: Suppress extraneous logging
The error paths of the common qcom-ufs functions for registering the
phy, acquiring clocks and acquiring regulators all print specific error
messages before returning an error, so there is no value in printing yet
another - more generic - message when this occur.

Vivek Gautam 3d4640f1cf phy: qcom-ufs: Remove common layer phy exit callback
The common layer phy exit callback ufs_qcom_phy_exit()
calls phy_power_off() that has no meaning when phy_power_off()
callback is already registered with the phy provider and
the consumer makes use of the same.
Instead, add a no-op specific phy_exit() callback for now
to add the exit sequence at a later point.

Vivek Gautam 9c7ce698ba phy: qcom-ufs-qmp-xx: Move clock and regulator init out of phy init
The phy init is meant to do phy initialization rather than
just getting the clock and regulator. Move these clock and
regulator get to probe(), to make room for actual phy
initialization sequence.

Vivek Gautam a378508d36 phy: qcom-ufs-qmp-xx: Discard remove callback for drivers.
remove() callback does a phy_power_off() only over the phy,
and nothing else now.
The phy_power_off() over the generic phy is called from the phy
consumer, and phy provider driver should not explicitly need to
call any phy ops.
So discard the remove callback for qcom-ufs phy platform drivers.

Vivek Gautam e41973769b phy: qcom-ufs-14nm: Add new compatible for msm8996 based phy
Add a new compatible string for 14nm ufs phy present on msm8996
chipset. This phy is bit different from the legacy 14nm ufs phy
in terms of the clocks that are needed to be handled in the driver.

Vivek Gautam 89bd296b78 phy: qcom-ufs: Cleanup clock and regulator initialization
Different menthods pass around generic phy pointer to
extract device pointer. Instead, pass the device pointer
directly between function calls.
