Hi Simon, Magnus,
This patch series adds the R-Car System Controller to the DTS files for
the various Renesas R-Car SoCs, and hooks up devices to their respective
PM domains.
This is a dependency for the enablement of DU and VSP on R-Car H3, as
on this SoC the VSPs are located in a PM Domain.
This series contains 2 parts:
1. Patches 1-6 add device node for the System Controllers, and hook
up CPU cores and L2 caches/SCUs to their respective PM Domains,
2. Patches 7-12 hook up devices to the SYSC "always-on" PM Domain, for
a more consistent device-power-area description in DT.
While part 1 is safe to apply, part 2 causes more deferred probing,
which exposes a few deficiencies in subsystems and drivers:
1. The PHY subsystem doesn't support deferred probe, so Micrel
KSZ8041RNLI (R-Car Gen2) or KSZ9031 (R-Car Gen3) falls back to
polling:
irq: no irq domain found for /interrupt-controller at e61c0000 !
Micrel KSZ8041RNLI ee700000.etherne:01: attached PHY driver [Micrel KSZ8041RNLI] (mii_bus:phy_addr=ee700000.etherne:01, irq=-1)
irq: no irq domain found for /soc/gpio at e6052000 !
Micrel KSZ9031 Gigabit PHY e6800000.etherne:00: attached PHY driver [Micrel KSZ9031 Gigabit PHY] (mii_bus:phy_addr=e6800000.etherne:00, irq=-1)
2. The Audio DMAC is now initialized after rcar_sound on R-Car Gen2
and Gen3, so rcar_sound falls back to PIO:
rcar_sound ec500000.sound: can't get dma channel
rcar_sound ec500000.sound: ssi[0] fallback to PIO mode
rcar_sound ec500000.sound: can't get dma channel
rcar_sound ec500000.sound: ssi[1] fallback to PIO mode
3. The System DMAC is now initialized after the SPI drivers on R-Car
Gen2, hence they fall back to PIO:
renesas_spi e6b10000.spi: dma_request_slave_channel_compat failed
renesas_spi e6b10000.spi: DMA not available, using PIO
spi_sh_msiof e6e20000.spi: dma_request_slave_channel_compat failed
spi_sh_msiof e6e20000.spi: DMA not available, using PIO
4. On r8a7790/lager, I see various i2c failures:
adv7180 6-0020: chip found @ 0x20 (e6520000.i2c)
adv7180: probe of 6-0020 failed with error -110
i2c 7-0058: Masking da9063 interrupt sources
i2c 7-0058: i2c error -110
da9063 7-0058: Cannot read FAULT_LOG.
da9063 7-0058: Cannot clear fault log
da9063 7-0058: Cannot read chip model id.
da9063: probe of 7-0058 failed with error -5
i2c 7-0068: Masking da9210 interrupt sources
i2c 7-0068: i2c error -110
da9210 7-0068: Failed to write to mask reg: -110
da9210: probe of 7-0068 failed with error -110
Hence for now I think it's best to just apply the first part, to allow
progress on R-Car H3, and postpone the second part until the issues are
sorted out.
Changes compared to v3:
- Add power-domains properties to the sysc nodes, to refer to the
SoC's Clock Domains,
- Extract using the SYSC "always-on" PM Domain on R-Car H3 into its
own patch,
- Add patches to use the SYSC "always-on" PM Domain on R-Car H1 and
R-Car Gen2,
- Update for recently added can0, can1, pciec0, and pciec1 device
nodes on R-Car H3.
Changes compared to v2:
- Move power area hierarchy from DT to C (cfr. DT bindings for Renesas
CPG/MSSR), and switch to "#power-domain-cells = <1>",
- Drop fallback compatibility strings, as the bindings are
SoC-specific,
- Add an "always-on" power area on R-Car H3.
Changes compared to v1:
- Add R-Car H3 (r8a7795) support,
- Use "renesas,<type>-sysc" instead of "renesas,sysc-<type>",
- Add fallback compatibility strings for R-Car Gen2 and Gen3.
Dependencies:
- renesas-devel-20160406-v4.6-rc2,
- "[PATCH v4 0/7] PM / Domains: Add DT bindings for the R-Car System
Controller",
- "[PATCH v4 00/11] soc: renesas: Add R-Car SYSC PM Domain Support".
Note that these are hard dependencies: adding SYSC PM Domains to DTS
files without driver support may cause breakage!
For your convenience, I've pushed this, incl. all dependencies, to the
topic/rcar-sysc-pd-v4 branch of
https://git.kernel.org/cgit/linux/kernel/git/geert/renesas-drivers.git
This has been tested on r8a7779/marzen, r8a7790/lager, r8a7791/koelsch,
r8a7794/alt, and r8a7795/salvator-x.
Thanks for applying part 1 (patches 1-6)!

Hi Geert,
Thank you for the patches.
Patches 01 to 06 look good to me expect for the power-domains = <&cpg_clocks>;
property as explained in a reply to the SYSC driver patches.
For patches 07 to 12,

> - Extract using the SYSC "always-on" PM Domain on R-Car H3 into its

> R-Car Gen2,
> - Update for recently added can0, can1, pciec0, and pciec1 device
> nodes on R-Car H3.
>
> Changes compared to v2:
> - Move power area hierarchy from DT to C (cfr. DT bindings for Renesas
> CPG/MSSR), and switch to "#power-domain-cells = <1>",
> - Drop fallback compatibility strings, as the bindings are
> SoC-specific,
> - Add an "always-on" power area on R-Car H3.
>
> Changes compared to v1:
> - Add R-Car H3 (r8a7795) support,
> - Use "renesas,<type>-sysc" instead of "renesas,sysc-<type>",
> - Add fallback compatibility strings for R-Car Gen2 and Gen3.

> - "[PATCH v4 00/11] soc: renesas: Add R-Car SYSC PM Domain Support".
