[PATCH 6.1.y-cip 00/21] Add support for Renesas RZ/G3E SoC and SMARC-EVK platform

[Tommaso Merciai]

Dear All,

This patch series adds initial support for the Renesas RZ/G3E SoC and
RZ/G3E SMARC EVK platform to linux-6.1.y-cip kernel. The RZ/G3E device is a
general-purpose microprocessor with a quad-core CA-55, single core CM-33,
Ethos-U55 NPU, Mali-G52 3-D Graphics and other peripherals.

All patches are cherry-picked from mainline kernel.

base commit:
 - d08cad4e6b10: serial: sh-sci: Increment the runtime usage counter for the earlycon device

[PATCH 6.1.y-cip 02/21] dt-bindings: soc: renesas: Document RZ/G3E SMARC SoM and Carrier-II EVK

[Tommaso Merciai]

From: Biju Das <biju.das.jz@bp.renesas.com>

commit 2bf1a3ca1df7ed93e5ac82ff672753a4edbb6e80 upstream.

Document the Renesas RZ/G3E SMARC Carrier-II EVK board which is based
on the Renesas RZ/G3E SMARC SoM. The RZ/G3E SMARC Carrier-II EVK
consists of an RZ/G3E SoM module and a SMARC Carrier-II carrier board.
The SoM module sits on top of the carrier board.

[PATCH 6.1.y-cip 03/21] dt-bindings: clock: renesas: Document RZ/V2H(P) SoC CPG

[Tommaso Merciai]

From: Lad Prabhakar <prabhakar.mahadev-lad.rj@bp.renesas.com>

commit afec1aba08607b18cfd00fdcd6525aeca0e187bf upstream.

Document the device tree bindings for the Renesas RZ/V2H(P) SoC
Clock Pulse Generator (CPG).

CPG block handles the below operations:
- Generation and control of clock signals for the IP modules
- Generation and control of resets
- Control over booting
- Low power consumption and power supply domains

Also define constants for the core clocks of the RZ/V2H(P) SoC. Note the
core clocks are a subset of the ones which are listed as part of section
4.4.2 of HW manual Rev.1.01 which cannot be controlled by CLKON register.

[PATCH 6.1.y-cip 08/21] clk: renesas: rzv2h: Add selective Runtime PM support for clocks

[Tommaso Merciai]

From: Lad Prabhakar <prabhakar.mahadev-lad.rj@bp.renesas.com>

commit 03108a2614ecab46af6e0d66f9fd61c0d80587f2 upstream.

Update `rzv2h_cpg_attach_dev` to prevent external and core clocks not tied
to the power domain from being managed by Runtime PM. This ensures that
only clocks originating from the domain are controlled, thereby avoiding
unintended handling of external and core clocks.

Additionally, introduce a `no_pm` flag in `mod_clock` and `rzv2h_mod_clk`
structures to exclude specific clocks from Runtime PM when needed. Some
clocks, such as those in the CRU block, require unique enable/disable
sequences that are incompatible with standard Runtime PM. For example,
the CSI-2 D-PHY clock initialization requires toggling individual clocks,
making Runtime PM unsuitable.

The helper function `rzv2h_cpg_is_pm_clk()` checks whether a clock should
be managed by Runtime PM based on this `no_pm` flag. New macros, such as
`DEF_MOD_NO_PM`, allow straightforward declaration of clocks that bypass
PM.

[PATCH 6.1.y-cip 12/21] clk: renesas: r9a09g057: Add support for PLLVDO, CRU clocks, and resets

[Tommaso Merciai]

From: Lad Prabhakar <prabhakar.mahadev-lad.rj@bp.renesas.com>

commit ee47b94102d2eaed23ac60910003cd0f3fade13c upstream.

Add support for the PLLVDO clock and its related CRU clocks and reset
entries in the r9a09g057 CPG driver. Introduce `CLK_PLLVDO` and associated
clocks like `CLK_PLLVDO_CRU0`, `CLK_PLLVDO_CRU1`, `CLK_PLLVDO_CRU2`, and
`CLK_PLLVDO_CRU3`, along with their corresponding dividers.

[PATCH 6.1.y-cip 13/21] clk: renesas: rzv2h: Add MSTOP support

[Tommaso Merciai]

From: Biju Das <biju.das.jz@bp.renesas.com>

commit 9b6e63a777ea5fb85bf24f9cb5ba902eed4f1f2f upstream.

Add MSTOP support to control buses for the individual units on RZ/V2H.
Use per-bit (instead of group-based) configuration and atomic counters,
to ensure precise control over individual MSTOP bits, and to prevent
issues with shared dependencies between module clocks.

[PATCH 6.1.y-cip 14/21] clk: renesas: rzv2h: Add support for RZ/G3E SoC

[Tommaso Merciai]

From: Biju Das <biju.das.jz@bp.renesas.com>

commit bb6a9aaf670735d6583c76073ec41190f5404dc5 upstream.

The clock structure for RZ/G3E is almost identical to RZ/V2H SoC with
more IP blocks compared to RZ/V2H. For eg: VSPI, LVDS, DPI and LCDC1
are present only on the RZ/G3E SoC.

Add minimal clock and reset entries required to boot the Renesas RZ/G3E
SMARC EVK and binds it with the RZ/V2H CPG core driver.

[PATCH 6.1.y-cip 16/21] arm64: dts: renesas: Add initial DTSI for RZ/G3E SoC

[Tommaso Merciai]

From: Biju Das <biju.das.jz@bp.renesas.com>

commit 9977754eeebed749a071492d98e46700307c0bd1 upstream.

Add the initial DTSI for the RZ/G3E SoC.
The files in this commit have the following meaning:
  - r9a09g047.dtsi:    RZ/G3E family SoC common parts
  - r9a09g047e57.dtsi: RZ/G3E R0A09G047E{4,5}{7,8} SoC specific parts
  - r9a09g047e37.dtsi: RZ/G3E R0A09G047E{2,3}{7,8} SoC specific parts

Normally, we use DEBUG for enabling debug prints, they should not
modify behaviour.

Are you sure this is safe to do? if id is more than num_core_clock,
we'll still proceed and do out-of-array read/write.

If this truly can not happen, that's okay, but...

Same here.

So this one is interesting. There's atomic_t,

but then it seems to be accessed under spinlock in all cases. Is
atomic_t needed? If so, comment why we still need the atomic would be
nice.

Ok, thanks for the series, it looks good to me.

Should I simply try to apply it to both 6.1 and 6.12? I guess I can do
that if there are no other comments.

I tested on my side and I can share that the following patches are needed
to boot the board on top of be95b49207284 (linux-6.12.y-cip):

Patches need some really small rework, (just moving up/down things to be
applied).

Thanks for the update! :)

Next step will be: pinctrl support

This for 6.1.y-cip will be a patchset from:

[6.1.y-cip,23/85] dt-bindings: pinctrl: renesas: Add alpha-numerical port support for RZ/V2H
..
to
[6.1.y-cip,64/85] arm64: dts: renesas: r9a09g047: Add pincontrol node
+
[6.1.y-cip,77/85] arm64: dts: renesas: r9a09g047e57-smarc: Add SCIF pincontrol


What do you think?
Thanks in advance.

I've tested the same on 6.12.y-cip. I can share that a smaller patchset
is required to bring up the pinctrl support + SCIF pincontrol on RZ/G3E.
