phy: qcom-qmp: Add SM8450 PCIe1 PHY support

2021-12-24T04:36:37+00:00

There are two different PCIe PHYs on SM8450, one having one lane (v5)
and another with two lanes (v5.20). This commit adds support for the
second PCIe phy.

phy: qcom-qmp: Add SM8450 PCIe0 PHY support

2021-12-18T05:55:07+00:00

There are two different PCIe PHYs on SM8450, one having one lane (v5)
and another with two lanes (v5.20). This commit adds support for the
first PCIe phy only, support for the second PCIe PHY is coming in next
commits.

phy: qcom-qmp: Add SM8450 USB QMP PHYs

2021-12-16T06:36:01+00:00

Add support for the USB DP & UNI PHYs found on SM8450. This is same as
the phy version used on SM8350 and sequences turned out to be same, so
use the same table from SM8350 for this as well.

phy: qcom: use struct_size instead of sizeof

2021-12-09T11:54:54+00:00

Use struct_size() to get the accurate size of `clk_hw_onecell_data`
with a variable size array, instead of sizeof(data) to get the size
of a pointer.

phy: qcom: Introduce new eDP PHY driver

2021-11-23T05:10:17+00:00

Many recent Qualcomm platforms comes with native DP and eDP support.
This consists of a controller in the MDSS and a QMP-like PHY.

While similar to the well known QMP block, the eDP PHY only has TX lanes
and the programming sequences are slightly different. Rather than
continuing the trend of parameterize the QMP driver to pieces, this
introduces the support as a new driver.

The registration of link and pixel clocks are borrowed from the QMP
driver. The non-DP link frequencies are omitted for now.

The eDP PHY is very similar to the dedicated (non-USB) DP PHY, but only
the prior is supported for now.
