05d5de6ba7 ARM: dts: dra76x: m_can: fix order of clocks
According to the bosch,m_can.yaml bindings the first clock shall be the "hclk",
while the second clock "cclk".

This patch fixes the order accordingly.

feedaacdad Input: atmel_mxt_ts - fix up inverted RESET handler
This driver uses GPIO descriptors to drive the touchscreen RESET line. In
the existing device trees this has in conflict with intution been flagged
as GPIO_ACTIVE_HIGH and the driver then applies the reverse action by
driving the line low (setting to 0) to enter reset state and driving the
line high (setting to 1) to get out of reset state.

The correct way to handle active low GPIO lines is to provide the
GPIO_ACTIVE_LOW in the device tree (thus properly describing the hardware)
and letting the GPIO framework invert the assertion (driving high) to a
low level and vice versa.

This is considered a bug since the device trees are incorrectly
mis-specifying the line as active high.

Fix the driver and all device trees specifying a reset line.

f73659192b net: wan: Delete the DLCI / SDLA drivers
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 8db60bcf3021 ("[WAN]: Remove broken and unmaintained Sangoma
drivers.") because the vendor no longer updated the in-kernel WANPIPE
driver.)

0f8159371c ARM: dts: s5pv210: Drop unneeded io-channel-ranges property in Aries
This property is only useful if a node has children as it allows them
to then use io-channel properties in the parent.  Here there are no
children.

This is harmless, but we are planning to shortly drop this property
as it is rarely used correctly and there is little reason it would
ever be needed as we can just provide the io-channels property to
any child nodes that need it.

9c87c9f412 ARM: SoC fixes for v5.10, part 2
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.

 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

cef3970381 arch: pgtable: define MAX_POSSIBLE_PHYSMEM_BITS where needed
Stefan Agner reported a bug when using zsram on 32-bit Arm machines

  Stack: (0xe376bbe0 to 0xe376c000)

As it turns out, zsram needs to know the maximum memory size, which
is defined in MAX_PHYSMEM_BITS when CONFIG_SPARSEMEM is set, or in
MAX_POSSIBLE_PHYSMEM_BITS on the x86 architecture.

The same problem will be hit on all 32-bit architectures that have a
physical address space larger than 4GB and happen to not enable sparsemem
and include asm/sparsemem.h from asm/pgtable.h.

After the initial discussion, I suggested just always defining
MAX_POSSIBLE_PHYSMEM_BITS whenever CONFIG_PHYS_ADDR_T_64BIT is
set, or provoking a build error otherwise. This addresses all
configurations that can currently have this runtime bug, but
leaves all other configurations unchanged.

I looked up the possible number of bits in source code and
datasheets, here is what I found:

 - on ARC, CONFIG_ARC_HAS_PAE40 controls whether 32 or 40 bits are used
 - on ARM, CONFIG_LPAE enables 40 bit addressing, without it we never
   support more than 32 bits, even though supersections in theory allow
   up to 40 bits as well.
 - on MIPS, some MIPS32r1 or later chips support 36 bits, and MIPS32r5
   XPA supports up to 60 bits in theory, but 40 bits are more than
   anyone will ever ship
 - On PowerPC, there are three different implementations of 36 bit
   addressing, but 32-bit is used without CONFIG_PTE_64BIT
 - On RISC-V, the normal page table format can support 34 bit
   addressing. There is no highmem support on RISC-V, so anything
   above 2GB is unused, but it might be useful to eventually support
   CONFIG_ZRAM for high pages.
