078dfef931 usb: ehci-mx6: Enable OTG detection on imx8mm and imx8mn
The imx8mm and imx8mn appear compatible with imx7d-usb
flags in the OTG driver.  If the dr_mode is defined as
host or peripheral, the device appears to operate correctly,
however the auto host/peripheral detection results in an error.

The solution isn't just adding checks for imx8mm and imx8mn to
the check for imx7, because the USB clock needs to be running
to read from the USBNC_PHY_STATUS_OFFSET register or it will hang.

Marek requested that I not enable the clocks in ehci_usb_of_to_plat,
so I modified that function to return an unknown state if the
device tree does not explicitly state whether it is a host
or a peripheral.

When the driver probes, it looks to see if it's in the unknown
state, and only then will it read the register to auto-detect.

0f513c5975 usb: ehci-mx6: use phy_type from device tree
Allow using different PHY interfaces for multiple USB controllers. When no
value is set in DT, we fall back to CONFIG_MXC_USB_PORTSC for now to stay
compatible with current board configurations.

This also adds support for the HSIC mode of the i.MX7.

4822114f4f usb: ehci-mx6: Do not fail when 'reg' is not found
Unlike imx6, on imx7 the USB PHY is described as:

	usbphynop1: usbphynop1 {
		compatible = "usb-nop-xceiv";
		clocks = <&clks IMX7D_USB_PHY1_CLK>;
		clock-names = "main_clk";
		#phy-cells = <0>;
	};

which does not have the 'reg' property.

Do not return an error when the 'reg' property is not found
for the USB PHY.

This fixes USB gadget regression on a imx7s-warp board.

Successfully tested the "ums 0 mmc 0" command on two boards:
imx7s-warp and imx6dl-pico-pi.

On a imx7s-warp board the fdtdec_get_alias_seq() function

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

8613c8d897 treewide: convert (void *)devfdt_get_addr() to dev_read_addr_ptr()
Use the _ptr suffixed variant instead of casting. Also, convert it to

One curious part is an error check like follows in
drivers/watchdog/omap_wdt.c:

    priv->regs = (struct wd_timer *)devfdt_get_addr(dev);
    if (!priv->regs)
            return -EINVAL;

devfdt_get_addr() returns FDT_ADDR_T_NONE (i.e. -1) on error.
So, this code does not catch any error in DT parsing.

dev_read_addr_ptr() returns NULL on error, so this error check
will work.

1198a104d3 usb: ehci-mx6: Fix bus enumeration for iMX7 SoCs
This fixes the issues with calculation of controller indexes in
ehci_usb_bind() for iMX7, as USB controllers on iMX7 SoCs aren't
placed next to each other, and their addresses incremented by 0x10000.

Example of USB nodes for iMX7S/D:

usbotg1: usb@30b10000 {
    compatible = "fsl,imx7d-usb", "fsl,imx27-usb";
    reg = <0x30b10000 0x200>;
           ^^^^^^^^^^
....
usbotg2: usb@30b20000 {
    compatible = "fsl,imx7d-usb", "fsl,imx27-usb";
    reg = <0x30b20000 0x200>;
           ^^^^^^^^^^
....

usbh: usb@30b30000 {
    compatible = "fsl,imx7d-usb", "fsl,imx27-usb";
    reg = <0x30b30000 0x200>;
           ^^^^^^^^^^
....

Which was leading to usb enumeration issues:
Colibri iMX7 # usb start

Bus usb@30b10000: USB EHCI 1.00

501547cec1 usb: ehci-mx6: Fix bus enumeration for DM case
The EHCI iMX6 driver is only partly converted to DT probing and
still uses a tremendous amount of hard-coded addresses. Worse,
the driver uses hard-coded SoC-model-specific base addresses, which
are derived from values protected by SoC-specific macros, hence the
driver is also compiled for a specific SoC model. Even worse, the
driver depends on specific sequential indexing of the controllers,
from which it derives offsets in the PHY and ANATOP register sets.

However, when the driver is probed from DT, the indexing is not
correct. In fact, each controller has index 0. This patch derives
the index for DT probing case from the controller base addresses,
which is not the way this should be done, however it is the least
intrusive approach, favorable this close to release.

The necessary steps to convert this driver fully to DT probing are
described inside the patch, however this should be done in the next
release and depends on iMX clock driver patches.

69535b33bc usb: ehci-mx6: Use common code to extract dr_mode
There exists code in drivers/common/common.c to read the dr_mode
from the device tree.  This patch converts this driver to use that
function to initialize the driver.

fd09c205fc usb: s/CONFIG_DM_USB/CONFIG_IS_ENABLED(DM_USB)/
This allows to disable the USB driver model in SPL because it checks
the CONFIG_SPL_DM_USB variable for SPL builds. Nothing changes for
regular non-SPL builds.

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.

552a848e4f imx: reorganize IMX code as other SOCs
Change is consistent with other SOCs and it is in preparation
for adding SOMs. SOC's related files are moved from cpu/ to
mach-imx/<SOC>.

This change is also coherent with the structure in kernel.

a821c4af79 dm: Rename dev_addr..() functions
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.
