[ Upstream commit 3ac2aa31b489eb4e0e820757f336aa1ad41ed0e2 ]
Add device tree binding support for the Gigabit Ethernet (GBETH) IP on
Renesas RZ/G3L SoC. This SoC uses different Synopsys DesignWare MAC
version 5.30 compared to RZ/G3E.
RZ/G3L requires an extra clock compared to RZ/G3E and has pps interrupts.
Add a new compatible string "renesas,r9a08g046-gbeth" for RZ/G3L SoC and
update the schema to handle hardware differences between SoC variants.
Extend the base snps,dwmac.yaml schema to accommodate the PPS interrupts.

[ Upstream commit 1ba377008420a63ba2cdbb3f5d1f9d30591f6c52 ]
Compared to other Renesas GBETH stmmac glue drivers, RZ/G3L GBETH IP use
the version Synopsys DesignWare MAC (version 5.30). It has an extra clock
compared to RZ/V2H and has ptp_pps_o interrupts. Add support for RZ/G3L
GBETH by reusing device data of RZ/V2H and can be extended to add other
functionalities later.

[ Upstream commit 653395e63d53723f29b8cc1aa6bc4cbb873c7b7b ]
RZ/G2L family clock drivers never had a need to nullify clocks.
Remove the unneeded checks.

[ Upstream commit b263e653c3722349a6efbb42d9e683d8ed1c24bf ]
The mstp_clock structure really represents a module clock (cfr. the
various rzg2l_mod_clock_*() functions and the to_mod_clock() helper),
and is not directly related to the "Module stop state".
Rename it to "mod_clock", and replace "mstp_clock" by "mod_clock".
to avoid confusion with the mstop registers.

Combine common code from rzg2l_cpg_assert() and rzg2l_cpg_deassert() into a
new __rzg2l_cpg_assert() helper to avoid code duplication. This reduces
maintenance effort and improves code clarity.

Prevent issues during reset deassertion by re-asserting the reset if a
timeout occurs when trying to deassert. This ensures the reset line is in a
known state and improves reliability for hardware that may not immediately
clear the reset monitor bit.

If the assert() fails due to timeout error, set the reset register bit
back to deasserted state. This change is needed especially for handling
assert error in suspend() callback that expect the device to be in
operational state in case of failure.

[ Upstream commit 3d700746d76bedb9f3de505494994cd3f2afb59f ]
Some reset lines must remain deasserted at all times after boot, as
asserting them would disable critical system functionality with no
owning driver to restore them. This mirrors the existing crit_mod_clks
mechanism which protects critical module clocks from being disabled.
On RZ/G2L family SoCs, the DMA reset must be remain deasserted for
routing some peripheral interrupts to CPU.
Add crit_resets and num_crit_resets fields to struct rzg2l_cpg_info to
allow SoC-specific data tables to declare reset IDs that must never be
asserted.
Introduce rzg2l_cpg_deassert_crit_resets() to iterate over all critical
resets and deassert them. Call it both at probe time and during resume
to ensure critical peripherals are held out of reset after power-on and
suspend/resume cycles.

[ Upstream commit 867fb0bc60602cb3c2458fcd25c841650d37563f ]
Refactor rzg2l_mod_clock_endisable() by extracting its logic into a new
helper function rzg2l_mod_clock_endisable_helper(), which accepts an
additional set_mstop_state boolean parameter. This allows callers to
control whether the module stop state is updated alongside the clock
enable/disable operation. No functional change for existing callers.

[ Upstream commit bf497e7babb5d14570b18b5d2c8a6bb14d4a733b ]
After a suspend/resume cycle, critical module clocks (CLK_IS_CRITICAL)
may be left disabled as there is no owning driver to restore them,
unlike regular clocks.
Add rzg2l_mod_enable_crit_clock_init_mstop() which walks all module
clocks on resume, re-enables any critical clock found disabled, and then
restores the MSTOP state for clocks that have one via the existing
helper. This replaces the direct call to rzg2l_mod_clock_init_mstop()
in rzg2l_cpg_resume(), preserving the correct clock-before-MSTOP restore
ordering.

[ Upstream commit 77894661c00ab99053c9606f0f7ec673065f86ac ]
The clock structure for RZ/G3L is almost identical to that of the RZ/G3S
SoC with more IP blocks such as LCDC, CRU, LVDS, and GPU.
Add minimal clock and reset entries required to boot the system on
Renesas RZ/G3L SMARC EVK and bind it with the RZ/G2L CPG core driver.

From: Biju Das <biju.das.jz@bp.renesas.com>
[ Upstream commit 78db1faa6b681da20ec167268b28778ebb0f98b7 ]
Add support for enabling PLL clocks in the RZ/G3L CPG driver to turn off
some PLLs, if they are not in use (e.g. PLL6, PLL7).
Introduce .is_enabled() and .enable() callbacks to handle PLL state
transitions. With the .enable() callback, the PLL will be turned ON
only when the PLL consumer device is enabled; otherwise, it will remain
off. Define new macros for PLL standby and monitor registers to
facilitate this process.

[ Upstream commit d55a0dfec40b6b820a0a391904daf8e74d6f0ec9 ]
Add clock and reset entries for the Gigabit Ethernet Interfaces (GBETH
0-1) IPs found on the RZ/G3L SoC. This includes various dividers and
mux clocks needed by these two GBETH IPs. Also add the tx, tx-180, rx,
rx-180, rmii, rmii-tx and rmii-rx clocks to the r9a08g046_no_pm_mod_clk
table to avoid enabling both normal and RMII clocks by the PM framework.

[ Upstream commit 7eeed6cd6a419f2f412aab29344a129e1c5c37f7 ]
The SMARC2 board DTSI is common to multiple SoCs. Move the USB3 nodes
to the board DTS, as some SoCs (e.g. RZ/G3[SL]) do not support USB3.

It was not as bad as series of 39 patches looked at first look; thanks
