The DLCI driver (dlci.c) implements the Frame Relay protocol. However,
we already have another newer and better implementation of Frame Relay
provided by the HDLC_FR driver (hdlc_fr.c).
The DLCI driver's implementation of Frame Relay is used by only one
hardware driver in the kernel - the SDLA driver (sdla.c).
The SDLA driver provides Frame Relay support for the Sangoma S50x devices.
However, the vendor provides their own driver (along with their own
multi-WAN-protocol implementations including Frame Relay), called WANPIPE.
I believe most users of the hardware would use the vendor-provided WANPIPE
driver instead.
(The WANPIPE driver was even once in the kernel, but was deleted in
commit 8db60bcf30 ("[WAN]: Remove broken and unmaintained Sangoma
drivers.") because the vendor no longer updated the in-kernel WANPIPE
driver.)

Around one third of the fixes this time are for dts files that list
their ethernet controller as using 'phy-mode="rgmii"' but are changed to
'phy-mode="rgmii-id"' now, because the PHY drivers (realtek, ksz9031,
dp83867, ...) now configure the internal delay based on that when they
used to stay on the hardware default.
The long story is archived at
https://lore.kernel.org/netdev/CAMj1kXEEF_Un-4NTaD5iUN0NoZYaJQn-rPediX0S6oRiuVuW-A@mail.gmail.com/
I was trying to hold off on the bugfixes until there was a solution that
would avoid breaking all boards, but that does not seem to be happening
any time soon, so I am now sending the correct version of the dts files to
ensure that at least these machines can use their network devices again.
The other changes this time are:
- Updating the MAINTAINER lists for Allwinner and Samsung SoCs
- Multiple i.MX8MN machines get updates for their CPU
operating points to match the data sheet
- A revert for a dts patch that caused a regression in USB
support on Odroid U3
- Two fixes for the AMD Tee driver, addressing a memory leak
and missing locking
- Mark the network subsystem on qoriq-fman3 as cache coherent
for correctness as better performance.
- Minor dts fixes elsewhere, addressing dtc warnings and similar
problems

ARM: 9019/1: kprobes: Avoid fortify_panic() when copying optprobe template
This reverts commit eaf2d2f689.
The commit eaf2d2f689 ("ARM: dts: exynos: add input clock to CMU in
Exynos4412 Odroid") breaks probing of usb3503 USB hub on Odroid U3.
It changes the order of clock drivers probe: the clkout (Exynos PMU)
driver is probed before the main clk-exynos4 driver. The clkout driver
on Exynos4412 depends on clk-exynos4 but it does not support deferred
probe, therefore this dependency and changed probe order causes probe
failure.
The usb3503 USB hub on Odroid U3 on the other hand requires clkout
clock. This can be seen in logs:

free_highpages() iterates over the free memblock regions in high
memory, and marks each page as available for the memory management
system.
Until commit cddb5ddf2b ("arm, xtensa: simplify initialization of
high memory pages") it rounded beginning of each region upwards and end of
each region downwards.
However, after that commit free_highmem() rounds the beginning and end of
each region downwards, and we may end up freeing a page that is
memblock_reserve()d, resulting in memory corruption.
Restore the original rounding of the region boundaries to avoid freeing
reserved pages.

Due to bug in the bootloader, the PHY has floating address and may
randomly change on each PHY reset. To avoid it, the updated bootloader
with the following patch[0] should be used:
| ARM: protonic: disable on-die termination to fix PHY bootstrapping
|
| If on-die termination is enabled, the RXC pin of iMX6 will be pulled
| high. Since we already have an 10K pull-down on board, the RXC level on
| PHY reset will be ~800mV, which is mostly interpreted as 1. On some
| reboots we get 0 instead and kernel can't detect the PHY properly.
|
| Since the default 0x020e07ac value is 0, it is sufficient to remove this
| entry from the affected imxcfg files.
|
| Since we get stable 0 on pin PHYADDR[2], the PHY address is changed from
| 4 to 0.
With latest bootloader update, the PHY address will be fixed to "0".

The ZII devel B board has two generations of Marvell Switches. The
mv88e6352 supports an MDIO clock of 12MHz. However the older 88e6185
does not like 12MHz, and often fails to probe.
Reduce the clock speed to 5MHz, which seems to work reliably.

This is a fairly large set of bug fixes on top of -rc1,
as most of them were ready but didn't quite make it into
the last-minute pull requests for the merge window.
Allwinner:
Fix for incorrect CPU overtemperature limit
Amlogic:
Multiple smaller DT bugfixes, and missing device nodes
Marvell EBU:
Add missing aliases for ethernet switch ports on
espressobin board
Marvell MMP:
One DTC warning fix
one bugfix for camera interface power-down
NXP i.MX:
Re-enable the GPIO driver on all defconfigs
ST STM32MP1:

I did not include a series of patches that work around a
regression caused by a bugfix in an ethernet phy driver
that resulted in an inadvertent DT binding change. This is
still under discussion.

These sections are handled by the ARM_UNWIND_SECTIONS define, which is
only added to the list of sections when CONFIG_ARM_UNWIND is set.
CONFIG_ARM_UNWIND is a hidden symbol that is only selected when
CONFIG_UNWINDER_ARM is set so CONFIG_UNWINDER_FRAME_POINTER never
handles these sections. According to the help text of
CONFIG_UNWINDER_ARM, these sections should be discarded so that the

i.MX SoC GPIO driver provides the basic functions of GPIO pin operations
and IRQ operations, it is now changed from "def_bool y" to "tristate", so
it should be explicitly enabled to make sure all consumers work normally.

Use a more generic form for __section that requires quotes to avoid
complications with clang and gcc differences.
Remove the quote operator # from compiler_attributes.h __section macro.
Convert all unquoted __section(foo) uses to quoted __section("foo").
Also convert __attribute__((section("foo"))) uses to __section("foo")
even if the __attribute__ has multiple list entry forms.
Conversion done using the script at:

Merge tag 'dma-mapping-5.10-1' of git://git.infradead.org/users/hch/dma-mapping
Pull dma-mapping fixes from Christoph Hellwig:
- document the new dma_{alloc,free}_pages() API
- two fixups for the dma-mapping.h split
* tag 'dma-mapping-5.10-1' of git://git.infradead.org/users/hch/dma-mapping:
dma-mapping: document dma_{alloc,free}_pages
dma-mapping: move more functions to dma-map-ops.h
ARM/sa1111: add a missing include of dma-map-ops.h
We keep this in a separate branch to avoid cross-branch conflicts, but
most of the material here is fairly boring -- some new drivers turned on
for hardware since they were merged, and some refreshed files due to
time having moved a lot of entries around.
