[PATCH v3 1/6] dt-bindings: mmc: cdns: document Microchip MPFS MMC/SDHCI controller

[PATCH v3 1/6] dt-bindings: mmc: cdns: document Microchip MPFS MMC/SDHCI controller

[Krzysztof Kozlowski]

The Microchip MPFS Icicle Kit uses Cadence SD/SDIO/eMMC Host Controller
without any additional vendor compatible:

  arch/riscv/boot/dts/microchip/microchip-mpfs-icicle-kit.dt.yaml: mmc@20008000: compatible:0: 'cdns,sd4hc' is not one of ['socionext,uniphier-sd4hc']
  arch/riscv/boot/dts/microchip/microchip-mpfs-icicle-kit.dt.yaml: mmc@20008000: compatible: ['cdns,sd4hc'] is too short

Signed-off-by: Krzysztof Kozlowski <krzysztof.kozlowski@canonical.com>

---

Changes since v2:
1. Document vendor compatible instead of dropping it.

[PATCH v3 2/6] riscv: dts: microchip: drop duplicated nodes

The DTSI file defines soc node and address/size cells, so there is no
point in duplicating it in DTS file.

Note that "model" should be "Microchip PolarFire SoC"
(with/without a hyphen? seems like the occurrence in
 microchip-mpfs-icicle-kit.dts is the only one with a hyphen)

[PATCH v3 4/6] riscv: dts: microchip: drop duplicated MMC/SDHC node

[Krzysztof Kozlowski]

Devicetree source is a description of hardware and hardware has only one
block @20008000 which can be configured either as eMMC or SDHC.  Having
two node for different modes is an obscure, unusual and confusing way to
configure it.  Instead the board file is supposed to customize the block
to its needs, e.g. to SDHC mode.

This fixes dtbs_check warning:
  arch/riscv/boot/dts/microchip/microchip-mpfs-icicle-kit.dt.yaml: sdhc@20008000: $nodename:0: 'sdhc@20008000' does not match '^mmc(@.*)?$'

Changes since v1:
1. Move also bus-width, suggested by Geert.

Hi Krzysztof,
Seems I missed most of this series other than the new vendor name in the V1.

We have been redoing the device tree for the mpfs/icicle kit partly dye 
to some changes we made to the design. Previously SD and eMMC were 
different FPGA designs but now both are in the same design and managed 
by the bootloader, depending on where it finds the image to boot from.
Since then we've just been using the following single entry in the .dtsi:

         mmc: mmc@20008000 { /* Common node entry for emmc/sd */
             compatible = "cdns,sd4hc";
             reg = <0x0 0x20008000 0x0 0x1000>;
             clocks = <&clkcfg CLK_MMC>;
             interrupt-parent = <&plic>;
             interrupts = <PLIC_INT_MMC_MAIN PLIC_INT_MMC_WAKEUP>;
             bus-width = <4>;
             cap-mmc-highspeed;
             cap-sd-highspeed;
             no-1-8-v;
             disable-wp;
             max-frequency = <200000000>;
             status = "disabled";
         };

CLK_MMC is 6 & the interrupt numbers are 88 and 89 respectively.

Cheers, Conor.

CLK_MMC is 6 & the interrupt numbers are 88 and 89 respectively.

Unfortunately your name does not appear as maintainer for these files
and get_maintainers.pl brings it only sometimes as a --git fallback.
Also few addresses from that --git fallback are non working, so I am not
always Cc-ing them. Sorry for that, I'll try to Cc you on next Microchip
RISC-V submissions, however you should probably add a proper platform
maintainer entry (similarly to ARM/ARM64 subarchitectures).

I'll switch to 2 interrupts.

I understand you prefer then the mmc node to be active? Before the DT
had SDHC one enable, so my patch did not introduce changes (except
mentioned interrupt).

I can change it to mmc above with your explanation.

Yeah, I just usually read every message and happened to miss part of the 
series.
Seems like none of my coworkers are listed against the device tree so 
I'll get someone added.

It's named mmc but it works for both SD card and eMMC, just depends on 
whats selected during boot. I'm not sure what is the appropriate thing 
to actually name the node in this case, maybe you know better than I do?
 > patch did not introduce changes
Yeah, I just figured that if changes are being made then its worth 
switching to the single entry now rather than waiting and doing it in a 
few weeks time.
