Bjorn Andersson f199223cb4 phy: qcom: Introduce new eDP PHY driver
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.

It should be [4:6] not [5:7]. Due to this incorrect definition, the BIT(7)

blocks ON during suspend.

Bjorn Andersson 34633219b8 phy: qmp: Provide unique clock names for DP clocks
The USB/DP combo PHY exposes the "qmp_dp_phy_pll_link_clk" and
"qmp_dp_phy_pll_vco_div_clk" clocks, that are consumed by the display
clock controller. But for boards with multiple enabled QMP USB/DP combo
instances the hard coded names collides - and hence only the first
probed device is allowed to register.

Given that clocks are no longer reference globally by name and it's
possible to replace the hard coded names by something unique, but still
user friendly.

The two new clock names are based on dev_name() and results in names
such as "88ee000.phy::link_clk" and "88ee000.phy::vco_div_clk".
