3cc537842f phy: rockchip: inno-usb2: fix phy reg=0 case
The support for #address-cells=2 has a loophole: if the reg is actually 0,
but the #address-cells is actually 1, like in such case below:

syscon {
	#address-cells = <1>;

	phy {
		reg = <0 0x10>;
	};
};

then the second u32 of the 'reg' is the size, not the address.

The code should check for the parent's #address-cells value, and not
assume that if the first u32 is 0, then the #address-cells is 2, and the
reg property is something like
	reg = <0 0xff00 0x10>;

Fixed this by looking for the #address-cells value and retrieving the
reg address only if this is ==2.
To avoid breaking anything I also kept the check `if reg==0` as some DT's
may have a wrong #address-cells as parent and even if this commit is
correct, it might break the existing wrong device-trees.

40359c9440 phy: rockchip-inno-usb2: Implement clock operations for usb2phy clock
This clock doesn't seem needed but appears in a phandle list used by
ehci-generic.c to bulk enable it. The phandle list comes from linux,
where it is needed for suspend/resume to work [1].

My tests give the same results with or without this patch, but Marek
Vasut found it weird to declare an empty clk_ops [2].

So I adapted the code from linux 6.1-rc8 so that it hopefully works
if it ever has some user. For now, without real use, it seems to
at least not give any errors when called.

e81512ac30 phy: rockchip-inno-usb2: Add usb2phy clock provider of 480MHz clock
arch/arm/dts/rk3399.dtsi has a node

  usb_host0_ehci: usb@fe380000 {
       compatible = "generic-ehci";

with clocks:

       clocks = <&cru HCLK_HOST0>, <&cru HCLK_HOST0_ARB>,
                <&u2phy0>;

The first 2 refer to nodes with class UCLASS_CLK, but &u2phy0
has class UCLASS_PHY.

  u2phy0: usb2phy@e450 {
       compatible = "rockchip,rk3399-usb2phy";

Since clk_get_bulk() only looks for devices with UCLASS_CLK,
it fails with -ENODEV and then ehci_usb_probe() aborts.

The consequence is peripherals connected to a USB 2 port (e.g. in a
Rock Pi 4 the white port, nearer the edge) not being detected.
They're detected if CONFIG_USB_OHCI_GENERIC is selected in Kconfig,
because ohci_usb_probe() does not abort when one clk_get_by_index()
fails, but then they work in USB 1 mode.

rk3399.dtsi comes from linux and the  u2phy0 was added[1] to the clock
list in:

    commit b5d1c57299734f5b54035ef2e61706b83041f20c
    Author: William wu <wulf@rock-chips.com>
    Date:   Wed Dec 21 18:41:05 2016 +0800

    arm64: dts: rockchip: add u2phy clock for ehci and ohci of rk3399

    We found that the suspend process was blocked when it run into
    ehci/ohci module due to clk-480m of usb2-phy was disabled.
    [...]

Suspend concerns don't apply to U-Boot, and the problem with U-Boot
failing to probe EHCI doesn't apply to linux, because in linux
rockchip_usb2phy_clk480m_register makes u2phy0 a proper clock provider
when called by rockchip_usb2phy_probe().

So I can think of a few alternative solutions:

1- Change ehci_usb_probe() to make it more similar to
   ohci_usb_probe(), and survive failure to get one clock. Looks a
   little harder, and I don't know whether it could break something if
   it ignored a clock that was important for something else than
   suspend.

2- Change rk3399.dtsi effectively reverting the linux commit
   b5d1c57299734f5b54035ef2e61706b83041f20c. This dealigns the .dtsi
   from linux and seems fragile at the next synchronisation.

3- Change the clock list in rk3399-u-boot.dtsi or somewhere else.
   This survives .dts* sync but may survive "too much" and miss some
   change from linux that we might want.

4- Enable CONFIG_USB_OHCI_GENERIC and use the ports in USB 1 mode.
   This would need to be made for all boards using rk3399.  In a
   simple test reading one file from USB storage it gave 769.5 KiB/s
   instead of 20.5 MiB/s with solution 2.

5- Trying to replicate linux and have usb2phy somehow provide a clk,
   or have a separate clock device for usb2phy in addition to the phy
   device.

This patch tries to implement option 5 as Marek Vasut requested in
December 5th.  Options 1 and 3 didn't get through [2][3].

It just registers usb2phy as a clock driver (device_bind_driver()
didn't work but device_bind_driver_to_node() did), without any
specific operations, so that ehci-generic.c finds it and is happy. It
worked in my tests on a Rock Pi 4 B+ (rk3399).

The fdt_addr_t and phys_addr_t size have been decoupled. A 32bit CPU
can expect 64-bit data from the device tree parser, so use
dev_read_addr_ptr instead of the dev_read_addr function in the
various files in the drivers directory that cast to a pointer.
As we are there also streamline the error response to -EINVAL on return.

3da15f0b49 phy: rockchip-inno-usb2: Add USB2 PHY for rk3568
RK3568 has two USB 2.0 PHYs, and each PHY has two ports, the OTG port
of PHY0 support OTG mode with charging detection function, they are
similar to previous Rockchip SoCs.

However, there are three different designs for RK3568 USB 2.0 PHY.
1. RK3568 uses independent USB GRF module for each USB 2.0 PHY.
2. RK3568 accesses the registers of USB 2.0 PHY IP directly by APB.
3. The two ports of USB 2.0 PHY share one interrupt.

This patch only PHY1 with necessary attributes required to function
USBPHY1 on U-Boot.

This construct is quite long-winded. In earlier days it made some sense
since auto-allocation was a strange concept. But with driver model now
used pretty universally, we can shorten this to 'auto'. This reduces
verbosity and makes it easier to read.

Coincidentally it also ensures that every declaration is on one line,
thus making dtoc's job easier.
