35fa673e0e sunxi: phy: Add USB PHY support for Allwinner H6
The USB PHY used in the Allwinner H6 SoC has some pecularities (as usual),
which require a small addition to the USB PHY driver:
In this case the second PHY is PHY3, not PHY1, so we need to skip number
1 and 2 in the code. Just use the respective code from Linux for that.

69aa1b234e phy: sun4i-usb: Update PHY#3 rst_mask only for H3_H5
Only H3 and H5 have 4 PHYS so restrict rst_mask only for them
by checking PHY id as 3 and update the proper bits.

52185b094d phy: sun4i-usb: Remove usb_clk_cfg set in probe
usb_clk_cfg is setting CTRL_PHYGATE bit value in probe
which is BIT 0 for sun4i, 6i and 8 for a83t but all
these were handling in phy ops init exit calls.

0bfcb47aa0 phy: sun4i-usb: Call phy_passby even for PHY#0
On newer Allwinner SoC, there is a pair of EHCI/OHCI USB hosts
for OTG host mode. USB PHY passby must be configured for its
corresponding PHY. so we can call for PHY#0. on the other hand
in past usb-phy code the same thing can be restricted for
Lower SoC's, other than H3/H5/A64.

Now there is no need to restrict usb passby since the phy driver
is DT enabled, and the respective phy calls will trigger based
DT information initiated by the drivers.

aa29b11b3f phy: sun4i-usb: Add a sunxi specific function for setting squelch-detect
The sunxi otg phy has a bug where it wrongly detects a high speed squelch
when reset on the root port gets de-asserted with a lo-speed device.

The workaround for this is to disable squelch detect before de-asserting
reset, and re-enabling it after the reset de-assert is done. Add a sunxi
specific phy function to allow the sunxi-musb glue to do this.

6768594326 phy: Add Allwinner A64 USB PHY driver
USB PHY implementation for Allwinner SOC's can be handling
in to single driver with different phy configs.

This driver handle all Allwinner USB PHY's start from 4I to
50I(except 9I). Currently added A64 compatibility more will
add in next coming patches.

Current implementation is unable to get pinctrl, clock and reset
details from DT since the dm code on these will add it future.

Driver named as phy-sun4i-usb.c since the same PHY logic
work for all Allwinner SOC's start from 4I to A64 except 9I
with different phy configurations.
