The HW user manual for the Renesas RZ/T2H and the RZ/N2H states that for
SDR104, SDR50, and HS200 to work properly the eMMC/SDHI interface pins
have to be configured as specified below:
- SDn_CLK pin - drive strength: Ultra High, slew rate: Fast,
- Other SDn_* pins: drive strength: High, slew rate: Fast,
Schmitt trigger: disabled (not applicable to SDn_RST pins).
HS DDR and DDR50 are currently not supported, and for every other bus
mode the eMMC/SDHI interface pins should be configured as specified
below:
- SDn_CLK pin - drive strength: High, slew rate: Fast,
- Other SDn_* pins: drive strength: Middle, slew rate: Fast,
Schmitt trigger: disabled (not applicable to SDn_RST pins).
Adjust the pin definitions accordingly.

The Renesas R-Car X5H (R8A78000) SoC contains Arm CoreLink GIC-720AE
Generic Interrupt Controller with Multi View capability. Firmware has
access to configuration View 0, Linux kernel has access to View 1.
The Arm CoreLink GIC-720AE Generic Interrupt Controller Technical
Reference Manual, currently latest r2p1 [1], chapter "5. Programmers
model for GIC-720AE", subchapter "5.4 Redistributor registers
for control and physical LPIs summary", part "5.4.3 GICR_TYPER,
Redistributor Type Register", "Table 5-50: GICR_TYPER bit descriptions"
on page 200, clarifies register "GICR_TYPER" bit 4 "Last" behavior
in Multi View setup as follows:
Last
Last Redistributor:
0 ... This Redistributor is not the last Redistributor on the chip.
1 ... This Redistributor is the last Redistributor on the chip.
When GICD_CFGID.VIEW == 1, for views 1, 2, or 3 this bit
always returns 1.
On this SoC, GICD_CFGID.VIEW is 1 and the Linux kernel has access to
View 1, therefore Linux kernel GICv3 driver will interpret register
"GICR_TYPER" bit 4 "Last" = 1 in the first Redistributor in continuous
Redistributor page as that first Redistributor being the one and only
Redistributor and will stop processing the continuous Redistributor
page further. This will prevent the other Redistributors from being
recognized by the system and used for other PEs.
Because the hardware indicates that the continuous Redistributor page
is not continuous for View 1, 2, or 3, describe every Redistributor
separately in the DT. This makes all Redistributors for all cores
accessible in Linux.

Move all differences into panel-aa104xd12.dtsi, rename OF_GRAPH links to
generic lvds_panel_out and lvds_panel_in names, and parametrize the LVDS
output in use using RENESAS_LVDS_OUTPUT macro. No functional change.

Enable the PCIE1 slot available on the RZ/V2N EVK.
Note, the PCIE_REFCLK comes from 5L35023B versa clock generator, once the
support for this clock generator is added, the fixed clock node can be
removed and can be replaced with a reference to the clock generator.

The SoC dtsi already defines the du node with its ports hierarchy,
including the du_out_rgb endpoint node under port@0. There is no need
to redefine the entire ports/port@0 structure in the board-level dtsi.

The TCIU8 interrupt used to be documented in earlier revisions of the
user manuals, but has since been removed. The corresponding entry is
now marked as reserved in the interrupt mapping tables of all supported
SoCs.

Rev.1.50 User Manual
Remove the TCIU8 interrupt. This does not cause any breakage as the
driver does not make use of the interrupts.

Describe coresight topology on R-Mobile APE6. Extend the current PTM node
with connection funnel, TPIU, ETB and replicator. The coresight on this
hardware is clocked from the ZT/ZTR trace clock.
Note that only core 0 part of the topology is described, because the
other cores are still not present in the DT.

Document the ZT trace bus and ZTR trace clocks on R-Mobile APE6. These
clocks supply the coresight tracing modules, PTM, TPIU, ETB and
replicator. Without these clocks, coresight tracing can not be
operated. While this does change the ABI, it does so by extending the
existing clock-output-names, therefore if old software is used with new
DT, the coresight tracing parts will likely fail to probe, otherwise if
new software is used with an old DT, there is no impact.
