This is a port of the corresponding commit in the Linux kernel which
adds the same support for the Cadence Torrent driver[0]. The commit
message below is taken as-is from the Linux kernel commit being ported.
The Torrent SERDES can support at most two different protocols (PHY types).
This only mandates that the device-tree sub-nodes used to represent the
configuration should describe links with at-most two different protocols.
The existing implementation however imposes an artificial constraint that
allows only two links (device-tree sub-nodes). As long as at-most two
protocols are chosen, using more than two links to describe them in an
alternating configuration is still a valid configuration of the Torrent
SERDES.
A 3-Link 2-Protocol configuration of the 4-Lane SERDES can be:
Lane 0 => Protocol 1 => Link 1
Lane 1 => Protocol 1 => Link 1
Lane 2 => Protocol 2 => Link 2
Lane 3 => Protocol 1 => Link 3
A 4-Link 2-Protocol configuration of the 4-Lane SERDES can be:
Lane 0 => Protocol 1 => Link 1
Lane 1 => Protocol 2 => Link 2
Lane 2 => Protocol 1 => Link 3
Lane 3 => Protocol 2 => Link 4

This PR introduces 3 new platforms, two from the new Dragonwing IQx
series (QCS615 and QCS8300) as well as the IPQ5424.
Additionally:
* Support for booting downstream Android boot images on some phones is
added
* Capsule update support is expanded to be more generic, determining
which partition U-Boot was flashed to automatically and supporting
many more boards.
* Minor capsule update bugs are fixed
* A watchdog driver is added and gets timeout support
* Autoboot now requires pressing "space" specifically to stop booting as
a workaround for some boards getting rogue key presses which would
cause autoboot to fail
* Documentation is added for the Dragonwing boards
* The RB1/2 now use USB gadget mode rather than host
* A bug is fixed where GPIO reads could return incorrect values

This patch enhances the Qualcomm watchdog driver by introducing
support for dynamic timeout configuration. Specifically:
- Calculates and sets the bark and bite timeout values based on
the clock rate and the requested timeout in milliseconds.
- Adds retrieval of the watchdog clock rate during probe using
the common clock framework.
- Adds a default timeout value for ARCH_SNAPDRAGON
in WATCHDOG_TIMEOUT_MSECS.
These changes improve the configurability and accuracy of the
watchdog timer on Qualcomm platforms.
This work builds upon the previous submission:

This patch series adds the functionality to print the DM firmware
version being used. Before requesting TISCI for the DM version we
first check if the DM split mode capability exists, if yes, we proceed
onto making the call to TISCI for retrieving the version information.
DM split mode capability indicates that the DM is a separate binary
altogether and has its own versioning information similar to TIFS.

Beleswar Padhi <b-padhi@ti.com> says:
This series adds remoteproc support on MCU R5F in Split mode.
During boot, ROM can bring up the boot R5F cores in either lockstep or
split mode based on X509 certificate flags. If booted in lockstep mode,
the MCU R5F cores will run first the R5 SPL, and then once A72 comes up,
will run the Device Manager (DM) firmware. But if booted in split mode, core
0 will run DM firmware and second core sits in WFI. Shut it down so that
other firmwares can later be loaded on them.
The shutdown of MCU R5 Core 1 is invoked at A72 SPL init, as by that
time Device Manager (DM) is up and running on R5 Core 0. The shutdown
of MCU R5 Core 1 is handled by Device Manager itself.

Rasmus Villemoes <ravi@prevas.dk> says:
While looking through list.h, I saw that the regular list_* helpers
(and one of the hlist_* ones) still contain the prefetch() that was
removed in linux 14 years ago. It doesn't do anything, but makes the
macros harder to read, so get rid of it, and the fallback, no-op
definition that they relied on. That requires removing a few uses
outside list.h as well.
checkpatch warns about some whitespace issues in list.h, but as I've
copied whole kerneldoc+#define blocks directly from the linux kernel,
I think it's better to just accept that so that we don't introduce
needless diffs. The "macro argument reuse" arguments should also be
ignored, as e.g. the "member" arguments are obviously always just bare
identifiers, and the "pos" arguments must be assigned to multiple
times.

These all end up using the no-op prefetch() defined in linux/list.h,
because the only possible real implementation is in

In order to be able to drop that fallback definition from list.h,

Contrary to the datasheet, setting both DETACH and PULLD_DIS bits to 1
does not always drive the DP and DM lines to high-impedance. This
prevents the host from reliably detecting a USB disconnect and subsequent
reconnect.
The symptom is that the first gadget command (e.g., dhcp) succeeds, while
subsequent commands (e.g., nfs) fail.
Disabling and re-enabling the controller entirely, instead of toggling the
PULLD_DIS bit, reliably generates a disconnect event.
The Linux driver works correctly because gadget_disconnect/gadget_connect
are always followed by gadget_udc_start/gadget_udc_stop. In U-Boot
pullup() is used solely.
This behavior has been observed on the SAM9X60-Curiosity and
AT91SAM9G25-EK boards and has been reported to Microchip.
