There is no reason to keep on using the __raw_{read,write}l() I/O
accessors in Renesas ARM driver code. Switch to using the plain
{read,write}l() I/O accessors, to have a chance that this works on
big-endian.

Memory controller drivers for v5.11 - Tegra SoC
There is a bigger work from Dmitry Osipenko around Tegra SoC memory
controller drivers, mostly towards adding interconnect support and
integration with devfreq. This work touches all Tegra memory controller
drivers and also few other SoC-related parts. It's not yet finished but
the intermediate stage seems ready to merge.
Beside that Tegra 210 memory controller got few fixes and received new
swgroups (work of Nicolin Chen).

According to Tegra X1 TRM, there are missing swgroups in the
tegra210_swgroups list. So this patch adds them to the list.
Note that the TEGRA_SWGROUP_GPU (in list) should be actually
TEGRA_SWGROUP_GPUB (in TRM), yet TEGRA_SWGROUP_GPU (in TRM) is not being
used -- only TEGRA_SWGROUP_GPUB (in TRM) is. So this patch does not add
TEGRA_SWGROUP_GPU (in TRM) and keeps TEGRA_SWGROUP_GPU (in list)
as it is.

Hardware issue:
- Reading register RCPM_IPPDEXPCR1 always return zero, this causes
system firmware could not get correct information and wrongly do
clock gating for all wakeup source IP during system suspend. Then
those IPs will never get chance to wake system.
Workaround:
- Copy register RCPM_IPPDEXPCR1's setting to register SCFG_SPARECR8
to allow system firmware's psci method read it and do things accordingly.

because these are the only platforms were the driver works properly.
2. Convert the Exynos CLKOUT driver to a full module which solves

Allwinner MBUS and DMA-ops rework
The Allwinner SoCs have a number of high-bandwidth devices connected to
a memory bus with a different RAM mapping than the CPU.
This was addressed before through drivers setting the DMA offsets
directly, and subsequently changed to calls to dma_direct_set_offset.
However that wasn't really meant to be exported to modules (and thus
drivers). The duplicated code also led to small inconsistencies across
drivers in how we dealt with DT backward compatibility.
Move all that DMA setup code into a platform bus notifier to share that
code and remove the export on dma_direct_set_offset.

The way that bpmp_populate_debugfs_inband() uses strncpy()
and strncat() makes no sense since the size argument for
the first is insufficient to contain the trailing '/'
and the second passes the length of the input rather than
the output, which triggers a warning:
In function 'strncat',
inlined from 'bpmp_populate_debugfs_inband' at ../drivers/firmware/tegra/bpmp-debugfs.c:422:4:
include/linux/string.h:289:30: warning: '__builtin_strncat' specified bound depends on the length of the source argument [-Wstringop-overflow=]
289 | #define __underlying_strncat __builtin_strncat
| ^
include/linux/string.h:367:10: note: in expansion of macro '__underlying_strncat'
367 | return __underlying_strncat(p, q, count);
| ^~~~~~~~~~~~~~~~~~~~
drivers/firmware/tegra/bpmp-debugfs.c: In function 'bpmp_populate_debugfs_inband':
include/linux/string.h:288:29: note: length computed here
288 | #define __underlying_strlen __builtin_strlen

include/linux/string.h:321:10: note: in expansion of macro '__underlying_strlen'

Simplify this to use an snprintf() instead.

The tegra_read_ram_code() is used by EMC drivers and we're going to make
these driver modular, hence this function needs to be exported.

We're going to modularize Tegra EMC drivers and some of the EMC-clock
driver symbols need to be exported.
