The rk3568 usb2phy has a single muxed interrupt that handles all
interrupts.
Allow the driver to plug in only a single interrupt as necessary.

New Rockchip devices have the usb phy nodes as standalone devices.
These nodes have register nodes with #address_cells = 2, but only use 32

Adjust the driver to check if the returned address is "0", and adjust

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.

Smatch complains that if of_get_address() returns NULL, then "size"
isn't initialized. Also it would lead to an Oops.

It can be necessary to adjust the phys settings to compensate parasitics.
This patch adds support of new optional properties to configure the tune
interface of the phys of stm32-usbphyc.
Properties are optional, that's why each property is skipped if not
found (-EINVAL).
Phy tuning is restored on resume because if deep low power state is
achieved, phy tuning configuration is reset.
