Add FCPF and FCPV instances to the r8a774a1 dtsi, similarly
to what was done for the r8a7796 with commit 41dbbf0c5b
("arm64: dts: r8a7796: Add FCPF and FCPV instances"),
commit 69490bc966 ("arm64: dts: renesas: r8a7796: Point
FDP1 via FCPF to IPMMU-VI0"), and commit cef942d0bd ("arm64:
dts: renesas: r8a7796: Point VSPI via FCPVI to IPMMU-VC0").

This patch adds definitions for L2 cache for the Cortex-A53 CPU
cores (512 KiB in size, organized as 32 KiB x 16 ways), adds
Cortex-A53 CPU cores (setting a total of 6 cores, 2 x Cortex-A57
+ 4 x Cortex-A53), and finally enables the performance monitor
unit for the Cortex-A53 cores on the R8A774A1 SoC.
Based on work done for r8a7796 SoC.

Add the device nodes for all RZ/G2M SCIF and HSCIF serial ports,
incl. clocks, power domains and DMAs.
According to the HW user manual, SCIF[015] and HSCIF[012] are
connected to both SYS-DMAC1 and SYS-DMAC2, while SCIF[34] and
HSCIF[34] are connected to SYS-DMAC0.

According to R-Car Gen3 HW manual rev1.00, R-Car M3-N has two CAN
interfaces, similar to H3, M3-W and other SoCs from the same family.
Add CAN placeholder nodes to avoid below DTC errors:
Error: arch/arm64/boot/dts/renesas/ulcb-kf.dtsi:19.1-6 Label or path can0 not found
Error: arch/arm64/boot/dts/renesas/ulcb-kf.dtsi:25.1-6 Label or path can1 not found
These errors occur *after* the addition of r8a77965-m3nulcb-kf.dts.
Fix them beforehand.
CAN support is inspired from below commits:
- v4.7 commit 308b7e4ba6 ("arm64: dts: r8a7795: Add CAN support")
- v4.11 commit 909c162524 ("arm64: dts: r8a7796: Add CAN support")
- v4.12 commit bec0948e81 ("arm64: dts: r8a7796: Add reset control properties")

For R-Car M3-N hook up SYS-DMAC0, SYS-DMAC1 and SYS-DMAC2 to
IPMMU-DS0 and IPMMU-DS1 in same way as for R-Car M3-W.
This follows the R-Car Gen3 Rev.1.00 (April 2018) datasheet.

The IPMMU nodes should follow the GEther node, not the CAN-FD node,
according to the <unit-address> part of the startng IPMMU-DS1 node.
While moving the nodes, also do sort them by label alphanumerically...

Browsing the DTS for all the R-Car SoCs with similar part numbers
makes my head hurt, so to improve the user friendliness of the
DTS code base include R-Car product name in each DTSI file.

Pull timer update from Thomas Gleixner:
"New defines for the compat time* types so they can be shared between
32bit and 64bit builds. Not used yet, but merging them now allows the
actual conversions to be merged through different maintainer trees
without dependencies
We still have compat interfaces for 32bit on 64bit even with the new
2038 safe timespec/val variants because pointer size is different. And
for the old style timespec/val interfaces we need yet another 'compat'
interface for both 32bit native and 32bit on 64bit"

Pull IDA updates from Matthew Wilcox:
"A better IDA API:
id = ida_alloc(ida, GFP_xxx);
ida_free(ida, id);
rather than the cumbersome ida_simple_get(), ida_simple_remove().
The new IDA API is similar to ida_simple_get() but better named. The
internal restructuring of the IDA code removes the bitmap
preallocation nonsense.
I hope the net -200 lines of code is convincing"
