[PATCH v2 00/16] Fix Qcom UFS PHY clocks

[PATCH v2 00/16] Fix Qcom UFS PHY clocks

[Manivannan Sadhasivam]

Hi,

This series fixes the clocks supplied to QMP PHY IPs in the Qcom SoCs. All
of the Qcom SoCs except MSM8996 require 3 clocks for QMP UFS:

* ref - 19.2MHz reference clock from RPM/RPMh
* ref_aux - Auxiliary reference clock from GCC
* qref - QREF clock from GCC or TCSR (TCSR since SM8550)

MSM8996 only requires 'ref' and 'qref' clocks.

Hence, this series fixes the binding, DT and GCC driver to reflect the
actual clock topology.

Note that the clock topology is not based on any downstream dts sources (even
they are not accurate). But rather based on information from Qcom internal
documentation and brain dump from Can Guo.

Testing
=======

Tested on Qualcomm RB5 development board based on SM8250 SoC. I don't
expect this series to break other SoCs too.

[PATCH v2 01/16] dt-bindings: phy: qmp-ufs: Fix PHY clocks

[Manivannan Sadhasivam]

All QMP UFS PHYs except MSM8996 require 3 clocks:

* ref - 19.2MHz reference clock from RPMh
* ref_aux - Auxiliary reference clock from GCC
* qref - QREF clock from GCC or TCSR (since SM8550)

MSM8996 only requires 'ref' and 'qref' clocks. Hence, fix the binding to
reflect the actual clock topology.

This change obviously breaks the ABI, but it is inevitable since the
clock topology needs to be accurately described in the binding.

This fails to apply on phy/fixes, pls rebase

[PATCH v2 02/16] phy: qcom-qmp-ufs: Switch to devm_clk_bulk_get_all() API

[Manivannan Sadhasivam]

Device drivers should just rely on the clocks provided by the devicetree
and enable/disable them based on the requirement. There is no need to
validate the clocks provided by devicetree in the driver. That's the job
of DT schema.

So let's switch to devm_clk_bulk_get_all() API that just gets the clocks
provided by devicetree and remove hardcoded clocks info.

While at it, let's move 'clocks' property before 'clock-names' to match

I'm not sure about this CLK. So I kept it as it is until I verify it.

I am quite sure everything *UFS_CARD_* refers to the other UFS host..

We cannot infer that from the naming. There is a chance that the same clock
could be routed to MEM_PHY internally. Moreover, there is no separate "ref"
clock for MEM_PHY though.

[PATCH v2 15/16] arm64: dts: qcom: sm8350: Fix UFS PHY clocks

QMP PHY used in SM8350 requires 3 clocks:

* ref - 19.2MHz reference clock from RPMh
* ref_aux - Auxiliary reference clock from GCC
* qref - QREF clock from GCC

While at it, let's move 'clocks' property before 'clock-names' to match
the style used commonly.
