RZ/V2H, RZ/V2N, and RZ/G3E support external audio clock inputs
(AUDIO_CLKA, AUDIO_CLKB, AUDIO_CLKC) that can be used by the Audio Clock
Generator (ADG) to derive internal audio clocks. These clocks are optional
and their frequencies are set by the board.
Update the bindings to allow these optional clocks for all RZ/V2H family
SoCs.

Add clock and reset entries for audio-related modules on the RZ/G3E SoC.
Target modules are:
- SSIU (Serial Sound Interface Unit) with SSI ch0-ch9
- SCU (Sampling Rate Converter Unit) with SRC ch0-ch9, DVC ch0-ch1,
CTU/MIX ch0-ch1
- ADMAC (Audio DMA Controller)
- ADG (Audio Clock Generator) with divider input clocks and audio
master clock outputs
While at it, reorder plldty_div16 to group it with other plldty fixed
dividers.

Some peripherals on RZ/G3E SoCs (SSIU, SPDIF, SCU/SRC, DVC) require
explicit ACK signal routing through the ICU via the ICU_DMACKSELk
registers for level-based DMA handshaking.
Add rzv2h_icu_register_dma_ack() to configure ICU_DMACKSELk, routing
a DMAC channel's ACK signal to the specified peripheral.

John Madieu
Some peripherals on RZ/G3E SoCs (SSIU, SPDIF, SCU/SRC, DVC, PFC) require
explicit ACK signal routing through the ICU for level-based DMA handshaking.
Rather than extending the DT binding with an optional second #dma-cells
(which would require all DMA consumers to supply two cells even when ACK
routing is not needed), derive the ACK signal number directly from the
MID/RID request number using the linear mapping defined in RZ/G3E hardware
manual Table 4.6-28:
PFC external DMA pins (DREQ0..DREQ4):
req_no 0x000-0x004 -> ACK No. 84-88
SSIU BUSIFs (ssip00..ssip93):
req_no 0x161-0x198 -> ACK No. 28-83
SPDIF (CH0..CH2) + SCU SRC (sr0..sr9) + DVC (cmd0..cmd1):
req_no 0x199-0x1b4 -> ACK No. 0-27
ACK routing is programmed when a channel is prepared for transfer and
cleared when the channel is released or the transfer times out, following
the same pattern as MID/RID request routing.
Signed-off-by: John Madieu <john.madieu.xa@bp.renesas.com>

Changes:
v2:
- Drop DMA ACK second cell from DT specifier
- Derive ACK signal number in-driver from MID/RID using arithmetic formulas
per ICU Table 4.6-28 (3 linear peripheral groups)

John Madieu
The current renesas,rsnd.yaml binding file handles all supported SoCs
in a single schema, resulting in deeply nested if/else/then constructs
that become increasingly difficult to maintain. Each new SoC addition
amplifies this complexity, making reviews harder and diffs noisier than
they need to be.
Refactor the binding by extracting the common properties shared across
all SoCs into a dedicated renesas,rsnd-common.yaml schema, and keeping
only SoC-specific constraints (required nodes, port counts, clock names,
etc.) in per-SoC or per-family files that $ref the common part.
This prepares the ground for upcoming SoCs such as the RZ/G3E, which
introduces a different set of audio resources compared to existing
R-Car Gen variants. With the split in place, adding RZ/G3E support
becomes a self-contained change that neither bloats a monolithic schema
nor buries new constraints inside ever-deeper conditional blocks.
No functional change in validation behaviour for existing device trees.

This is 'ports', not 'port', so not the right ref.

John Madieu
The RZ/G3E shares the same audio IP as the R-Car variants but differs
in several aspects: it supports up to 5 DMA controllers per audio
channel, requires additional clocks (47 total including per-SSI ADG
clocks, SCU domain clocks and SSIF supply) and additional reset lines
(14 total including SCU, ADG and Audio DMAC peri-peri resets).
Add a dedicated devicetree binding for the RZ/G3E sound controller.
The binding references the common renesas,rsnd-common.yaml schema for
shared property and subnode definitions.

The RZ/G3E SoC requires per-module reset control for the audio subsystem.
Add reset controller support to struct rsnd_mod and update rsnd_mod_init()
to accept and handle a reset_control parameter.

RZ/G3E audio subsystem has a different register layout compared to
R-Car Gen2/Gen3/Gen4, as described below:
- Different base address organization (SCU, ADG, SSIU, SSI as
separate regions accessed by name)
- Additional registers: AUDIO_CLK_SEL3, SSI_MODE3, SSI_CONTROL2
- Different register offsets within each region
Add RZ/G3E SoC's audio subsystem register layouts and probe support.

Changes:
v2:
- Reuse existing RSND_BASE_xxx defines instead of RZ/G3E-specific ones;
- Fix ADG regmap init region count and collapse to single-line calls.
- Move RSND_RZG3E flag to separate bit range (xx << 8/12) to reserve
(x << 0) for future R-Car Gen5, using Morimoto-san's RSND_RZ_MASK scheme.

RZ/G3E requires additional audmapp clock and reset lines for
Audio DMA-PP operation.
Add global audmacpp clock/reset management in rsnd_dma_probe()
using optional APIs to remain transparent to other platforms.

RZ/G3E has different DMA register base addresses and offset
calculations compared to R-Car platforms.
Add dedicated rsnd_rzg3e_dma_addr() function with dispatch from
rsnd_dma_addr(), following the existing per-generation pattern.

Changes:
v2:
- Split into separate patches: one for DMA address support, one for
audmac-pp clock/reset management
- Replace ternary macro wrappers with dedicated rsnd_rzg3e_dma_addr()
function dispatched from rsnd_dma_addr(), following existing
rsnd_gen4_dma_addr() pattern

Add support for the SSIU found on the Renesas RZ/G3E SoC, which
provides a different BUSIF layout compared to earlier generations:
- SSI0-SSI4: 4 BUSIF instances each (BUSIF0-3)
- SSI5-SSI8: 1 BUSIF instance each (BUSIF0 only)
- SSI9: 4 BUSIF instances (BUSIF0-3)
- Total: 28 BUSIFs
RZ/G3E also differs from Gen2/Gen3 implementations in that only two
pairs of BUSIF error-status registers are available instead of four,
and the SSI always operates in BUSIF mode with no PIO fallback.
Rather than scattering SoC-specific checks across functional code,
introduce an extra capability flags in the match data:
- RSND_SSIU_BUSIF_STATUS_COUNT_2: only two BUSIF error-status
register pairs are present. Used in rsnd_ssiu_busif_err_irq_ctrl()
and rsnd_ssiu_busif_err_status_clear() to limit register iteration.
Future SoCs sharing these constraints can set the flags without
requiring code changes.

Changes:
v2:
- Droped RSND_SSI_ALWAYS_BUSIF flag; PIO is only enabled explicitly,
so no guard needed; use direct rsnd_is_rzg3e() check for skipping
SSI_MODE0 instead

Add SSI reset support for the Renesas RZ/G3E SoC, which differs from earlier
generations in several ways:
- The SSI block always operates in BUSIF mode; RZ/G3E does not implement
the SSITDR/SSIRDR registers used by R-Car Gen2/Gen3/Gen4 for direct SSI
DMA. Consequently, all audio data must pass through BUSIF.
- Each SSI instance has its own reset line, exposed using per-SSI names
such as "ssi0", "ssi1", etc., rather than a single shared reset.
To support these differences, rsnd_ssi_use_busif() always return 1 on
RZ/G3E, ensuring that the driver consistently selects the BUSIF DMA path.
While at it, update the reset acquisition logic to request the appropriate
per-SSI reset controller based on the SSI instance name.

Changes:
v2:
- Drop rsnd_dma_detach() from rsnd_ssi_common_remove() upon NULL pointer
dereference on R-Car Gen3/Gen4 (reported by Geert)
- Drop RSND_SSI_ALWAYS_BUSIF flag; use direct rsnd_is_rzg3e() check instead

RZ/G3E requires the ADG reset line to be deasserted for the audio
subsystem to operate. The ADG module clock is already managed via
rsnd_adg_clk_enable/disable() through adg->adg, so no additional
clock handling is needed.
Add support for the optional "adg" reset control on Renesas RZ/G3E SoC.

RZ/G3E's ADG module requires explicit clock management for SSI audio
interfaces that differs from R-Car Gen2/Gen3/Gen4:
- Per-SSI ADG clocks (adg.ssi.N) for each SSI module
- A shared SSIF supply clock for the SSI subsystem
These clocks are acquired using optional APIs, making them transparent
to platforms that do not require them.
Additionally, since rsnd_adg_ssi_clk_try_start() is called from the
trigger path (atomic context), clk_prepare_enable() cannot be used
directly as clk_prepare() may sleep. Split clock handling into:
- hw_params: clk_prepare() - sleepable context
- trigger (start): clk_enable() - atomic safe
- trigger (stop): clk_disable() - atomic safe
- hw_free: clk_unprepare() - sleepable context

John Madieu
The RZ/G3E SoC requires explicit SCU (Sampling Rate Converter Unit)
reset and clock management unlike previous R-Car generations:
- scu_clk: SCU module clock
- scu_clkx2: SCU double-rate clock
- scu_supply_clk: SCU supply clock
Without these clocks enabled, the SRC module cannot operate on RZ/G3E.
Add support for the shared SCU reset controller used by the SRC modules
on the Renesas RZ/G3E SoC. All SRC instances are gated by the same "scu"
reset line.

Add rsnd_adg_mod_get() to retrieve the ADG module handle.
This is preparation for system suspend/resume support, where the PM
callbacks need to access the ADG module to manage its clock and reset
state. Other modules (SSI, SRC, CTU, MIX, DVC) already have their
getters exported.

Remove the static qualifier from rsnd_ssiu_mod_get() and export it
via rsnd.h.
This is preparation for system suspend/resume support, where the PM

Add per-module suspend/resume functions following the existing driver
architecture where each module manages its own resources in its own
file. core.c provides common clock/reset helpers and orchestrates the
calls in the correct order (reverse probe for suspend, probe order
for resume).
Infrastructure clocks (ADG, audmacpp, SCU) are managed globally
using optional APIs to remain transparent to platforms that don't
specify these clocks/resets.

Model external audio clock inputs as CPG input clocks for RZ/V2H family
SoCs (RZ/V2H, RZ/V2N, RZ/G3E), allowing the Audio Clock Generator (ADG)
to derive internal audio clocks from these external sources.
The clock frequencies are board-specific and must be overridden in the
board DTS files.

Add the rzg3e_sound node for the RZ/G3E SoC with all sub-components:
- SSI (Serial Sound Interface) units 0-9
- SSIU (Serial Sound Interface Unit) units 0-27
- SRC (Sample Rate Converter) units 0-9
- CTU (Channel Transfer Unit) units 0-7
- DVC (Digital Volume Control) units 0-1
- MIX (Mixer) units 0-1
Wire up all 5 DMA controllers (dmac0-dmac4) for each audio sub-node
with repeated channel names, so that the DMA core can pick the first
available controller.

Add the Renesas 5P35023 (Versa3) programmable clock generator on the
I2C2 bus along with its 24MHz input clock (x2 oscillator) to feed the
audio subsystem.
The Versa3 provides the following audio-related clock outputs:
- Output 0: 24MHz (reference)
- Output 1: 12.288MHz (audio, 48kHz family)
- Output 2: 11.2896MHz (audio, 44.1kHz family)
- Output 3: 12.288MHz (audio)
These clocks are required for the audio codec found on the RZ/G3E SMARC
EVK.

Add and enable I2C1 controller support with pin configuration.
The I2C1 bus is routed to the carrier board and used for peripherals
such as the audio codec.

RZ/G3E SMARC board has a DA7212 audio codec connected via I2C1 for
sound input/output using SSI3/SSI4 where:
- The codec receives its master clock from the Versa3 clock
generator present on the SoM
- SSI4 shares clock pins with SSI3 to provide a separate data
line for full-duplex audio capture.
Enable audio support on RZ/G3E SMARC2 EVK boards with a DA7212 audio codec.

My bad. Sorry for not taking care of it. I'll split into
subsystem-specific serieses and send the v3.
