d7d7606c7e phy: Add USB PHY driver for the MT76x8 (7628/7688) SoC
This driver is derived from this Linux driver:
linux/drivers/phy/ralink/phy-ralink-usb.c

The driver sets up power and host mode, but also needs to configure PHY
registers for the MT7628 and MT7688.

I removed the reset controller handling for the USB host and device, as
it does not seem to be necessary right now. The soft reset bits for both
devices are enabled by default and testing has shown (with hackish
reset handling added), that USB related commands work identical with
or without the reset handling.

Please note that the resulting USB support is tested only very minimal.
I was able to detect one of my 3 currently available USB sticks.
Perhaps some further work is needed to fully support the EHCI controller
integrated in the MT76x8 SoC.

4b8cb84327 phy: marvell: Support changing SERDES map in board file
This adds a weak definition of comphy_update_map to comphy_core,
which does nothing. If this function is defined elsewhere, for example
in board file, the board file can change some parameters of SERDES
configuration.

This is needed on Turris Mox, where the SERDES speed on lane 1 has to
be set differently when SFP module is connected and when Topaz Switch
module is connected.

This is a temporary solution. When the comphy driver for armada-3720
will be added to the kernel, the comphy driver in u-boot shall also be
updated and this should be done differently then.

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.

a1b2faed7c phy: Be able to get phy from PHY provider
In case of phy are provided from a PHY provider nodes as following:

usbphyc: usb-phy@5a006000 {
	compatible = "st,stm32mp1-usbphyc";
	reg = <0x5a006000 0x1000>;
	clocks = <&rcc_clk USBPHY_K>;

	#address-cells = <1>;
	#size-cells = <0>;

	usbphyc_port0: usb-phy@0 {
		reg = <0>;
		phy-supply = <&vdd_usb>;
		vdda1v1-supply = <&reg11>;
		vdda1v8-supply = <&reg18>
		#phy-cells = <0>;
	};

	usbphyc_port1: usb-phy@1 {
		reg = <1>;
		phy-supply = <&vdd_usb>;
		vdda1v1-supply = <&reg11>;
		vdda1v8-supply = <&reg18>
		#phy-cells = <1>;
	};
};

and PHY are called as following:

usbh_ehci: usbh-ehci@5800d000 {
	compatible = "generic-ehci";
	reg = <0x5800d000 0x1000>;
	clocks = <&rcc_clk USBH>;
	resets = <&rcc_rst USBH_R>;
	interrupts = <GIC_SPI 75 IRQ_TYPE_NONE>;
	companion = <&usbh_ohci>;
	phys = <&usbphyc_port0>;
	phy-names = "usb";
	status = "okay";
};

generic_phy_get_by_index() must be updated to first look for
PHY phandle as previously and in case of error looks for PHY
provider by finding the parent's current node which is the PHY
provider.
args (ofnode_phandle_args struct) must also be updated by inserting
the phy index into the PHY provider as args[0].

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.

Current implementation is unable to get pinctrl, clock and reset

7d7f22fbd3 phy: marvell: a3700: revise the USB3 comphy setting during power on
This commit is based on commit d9899826 by
  zachary <zhangzg@marvell.com>
from u-boot-marvell, see
github.com/MarvellEmbeddedProcessors/u-boot-marvell/commit/d9899826

- According to design specification, the transmitter should be set to high
  impedence mode during electrical idle. Thus transmitter should detect RX
  at high impedence mode also, and delay is needed to accommodate high
  impedence off latency. Otherwise the USB3 will have detection issue that
  most of the time the USB3 device can not be detected at all, or be
  detected as USB2 device sometimes.
  Modified registers: RD005C302h (R181h) (0051h) Lane Configuration 1
  Bit 6: set to 1 to let Tx detect Rx at HiZ mode
  Bit [3:4]: set to 2 to be delayed by 2 clock cycles
  Bit 0: set to 1 to set transmitter to high impedance mode during idle.
- USB3 De-emphasize level of -3.5dB is mandatory, but USB3 MAC selects 0x2
  (emphasize disabled) in the MAC_PHY_TXDEEMPH [1:0], while it is supposed
  to select 0x1(3.5dB emphasize). Thus need to override what comes from
  the MAC(by setting register 0x1c2 bit2 to 0x1) and to configure the
  overridded values of MAC_PHY_TXDEEMPH [1:0] to 0x1(bit15 of register
  0x181 and bit0 of register 0x180).
- According to USB3 application note, need to update below comphy
  registers:
  Set max speed generation to USB3.0 5Gbps(set RD005C04Ah bit[11:10] to 1)
  Set capacitor value to 0xF(set RF005C224 bit[3:0] to 0xF)

210f4aae81 phy: marvell: a3700: Don't create functional macro for each register
Currently there is for each register special functional macro, ie:
  LANE_CFG1_ADDR(u)
  GLOB_CLK_SRC_LO_ADDR(u)
  ...
where can be either PCIE or USB3.

Change this to one function PHY_ADDR(unit, addr). The code becomes:
  phy_addr(PCIE, LANE_CFG1)
  phy_addr(PCIE, GLOB_CLK_SRC_LO)
  ...

d35812368a regmap: change regmap_init_mem() to take ofnode instead udevice

has already been associated with a device. It prevents syscon/regmap
from behaving like those in Linux.

8c1de5e08b regmap: clean up regmap allocation
Putting zero length array at the end of struct is a common technique
to embed arbitrary length of members.  There is no good reason to let
regmap_alloc_count() branch by "if (count <= 1)".

As far as I understood the code, regmap->base is an alias of
regmap->ranges[0].start, but it is not helpful but make the code
just ugly.

Rename regmap_alloc_count() to regmap_alloc() because the _count
suffix seems pointless.

83d290c56f SPDX: Convert all of our single license tags to Linux Kernel style
When U-Boot started using SPDX tags we were among the early adopters and
there weren't a lot of other examples to borrow from.  So we picked the
area of the file that usually had a full license text and replaced it
with an appropriate SPDX-License-Identifier: entry.  Since then, the
Linux Kernel has adopted SPDX tags and they place it as the very first
line in a file (except where shebangs are used, then it's second line)
and with slightly different comment styles than us.

In part due to community overlap, in part due to better tag visibility
and in part for other minor reasons, switch over to that style.

This commit changes all instances where we have a single declared
license in the tag as both the before and after are identical in tag
contents.  There's also a few places where I found we did not have a tag
and have introduced one.

9b643e312d treewide: replace with error() with pr_err()
U-Boot widely uses error() as a bit noisier variant of printf().

This macro causes name conflict with the following line in
include/linux/compiler-gcc.h:

  # define __compiletime_error(message) __attribute__((error(message)))

This prevents us from using __compiletime_error(), and makes it
difficult to fully sync BUILD_BUG macros with Linux.  (Notice
Linux's BUILD_BUG_ON_MSG is implemented by using compiletime_assert().)

Let's convert error() into now treewide-available pr_err().

Done with the help of Coccinelle, excluing tools/ directory.

The semantic patch I used is as follows:

// <smpl>
@@@@
-error
+pr_err
 (...)
// </smpl>

These support the flat device tree. We want to use the dev_read_..()
prefix for functions that support both flat tree and live tree. So rename
the existing functions to avoid confusion.

In the end we will have:

   1. dev_read_addr...()    - works on devices, supports flat/live tree
   2. devfdt_get_addr...()  - current functions, flat tree only
   3. of_get_address() etc. - new functions, live tree only

All drivers will be written to use 1. That function will in turn call
either 2 or 3 depending on whether the flat or live tree is in use.

Note this involves changing some dead code - the imx_lpi2c.c file.
