[PATCH 0/2] Cleanup the call ordering of phy_init and phy_power_on

[Jules Maselbas <jmaselbas@kalray.eu>]

Hi,

Last year Ahmad asked what is the correct order when calling phy_init
and phy_power_on. Since then, I didn't see the situation improve much
and I am once again toying around with usb phy driver.

The following two patches were in my tree for a year... Last year i
previously tried to change the call order in the dwc2 driver but this
requires the relevent phy to be also compatible with the "new" ordering.
The stm32-usbphyc driver wasn't compatible, I am not sure if that is
still is the case.

For now simply add documentation, hopefully correct, but I am not an
expert on actual phy sementics or usage in the kernel. And add warning
when the order is not what's expected.

Best,

Jules Maselbas (2):
  phy: core: Add documentation of phy operation order
  phy: core: Warn when phy_power_on is called before phy_init
