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
starting USB...
Bus usb@30b10000: USB EHCI 1.00
Bus usb@30b20000: probe failed, error -22

The mode selection for the DWC3 is kind of obsolete. The driver does not
have to be host only or gadget only. This choice is confusing.

Currently the host driver used by dwc3-generic is "xhci-dwc3". This is
a functional driver but it doesn't use the dwc3 core and, in particular,
it lacks some bits that may be important.
For example on the k2 platforms, it is important that the phy are properly
suspended when the USB is not used anymore. The dwc3 core also has a
partial support for quirks.
The new driver can be used as a drop-in replacement for "xhci-dwc3".
In terms of implementation, it may seem strange that 2 private structures
dwc3_generic_host_priv and dwc3_generic_priv) are used. The reason for this
is simply that the xhci layer expects a struct xhci_ctrl at the beginning
of the private data and it seemed wasteful to include it also for the
peripheral case.

Make sure that the clock self-assignment works by having a clock of
clk-sbox be configured automatically when clk-sbox is probed.
Signed-off-by: Jean-Jacques Hiblot <jjhiblot@ti.com>
This fixes the case where assigned-clocks is used to define a clock
defaults inside this same clock's node. This is used sometimes to setup a
default parents and/or rate for a clock.
example:
muxed_clock: muxed_clock {
clocks = <&clk_provider 0>, <&clk_provider 1>;
#clock-cells = <0>;
assigned-clocks = <&muxed_clock>;
assigned-clock-parents = <&clk_provider 1>;
};
It doesn't work in u-boot because the assigned-clocks are setup *before*
the clock is probed. (clk_set_parent() will likely crash or fail if called
before the device probe function)
Making it work by handling "assigned-clocks" in 2 steps: first before the
clk device is probed, and then after the clk device is probed.

This rm68200 panel driver is based on the Linux Kernel driver from
drivers/gpu/drm/panel/panel-raydium-rm68200.c.

Display Serial Interface (DSI) host can usefully be modelled
as their own uclass.
DSI defines a serial bus and a communication protocol
between the host and the device (panel, bridge).

Add support for CDCE913/925/937/949 family of devices. These are modular
PLL-based low cost, high performance, programmable clock synthesizers,
multipliers and dividers. They generate up to 9 output clocks from a
single input frequency. The initial version of the driver does not
support programming of the PLLs, and thus they run in the bypass mode
only. The code is loosely based on the linux kernel cdce9xx driver.

Power-domain is enabled by default in device_probe. am654 mmc driver
is enabling power-domain again in probe. As the second call is
redundant, drop power_domain_on from probe.

Regulator should not be enabled at probe time if regulator-boot-on
property is not in the dt node.
"enable-active-high" property is only used to indicate the GPIO
polarity.

The driver provides PHY for USB2, USB3.0, PCIe and SATA, and now
we just enable PCIe. As for the other functionalities will be
added gradually in upcoming days.
This is adapted from the Linux version.

The Broadcom ARM implementations do not yet have a clock framework so
one can use a fixed clock as the root clock of the hsspi block. The
fixed clock does not have an "enable" routine, since it's always
enabled. So when we hit this issue, getting an ENOSYS return, do not
bail but continue initialization.
Similarly the block might already have been out of reset, say, when
we are booting from a SPI device. So if the reset signal is not configured
in the device tree, do not bail out and instead skip deasserting the reset.

Make the driver compatible with both big and little endian SOCs.
Replace big-endian calls with their raw equivalents, expect for
writing the command to FIFO. That still has to be in big-endian
format.

SoCs with K3 architecture have an integrated Arm Cortex-R5F subsystem
that is comprised of dual-core Arm Cortex-R5F processor cores. This R5
subsytem can be configured at boot time to be either run in a LockStep
mode or in an Asymmetric Multi Processing (AMP) fashion in Split-mode.
This subsystem has each Tightly-Coupled Memory (TCM) internal memories
for each core split between two banks - TCMA and TCMB.
Add a remoteproc driver to support this subsystem to be able to load
and boot the R5 cores primarily in LockStep mode or split mode.
