[PATCH 1/1] arm64: dts: meson: g12b: odroid-n2: Assign a fixed index to mmc devices

[Alexander Stein]

Recently introduced async probe on mmc devices can shuffle block IDs.
Pin them to fixed values to ease booting in environments where UUIDs
are not practical. Use newly introduced aliases for mmcblk devices from [1].

I was wondering which order I should use. Depending in your booting
medium (SD card or eMMC) you 'want' one or the other as mmc0.
In the end I ordered them according to the names.

I understand the goal, and this should be done for _all_ boards, not only the Odroid-N2.

I see. So there are 2 options:
1.
Set the mapping for all 3 sd_emmc_* in the top-most .dtsi
Upside: very easy patch
Downside: When sd_emmc_a is not enabled "mmc0" will never be available.
Might be confusing.

2.
Set mapping only for enabled sd_emmc_* in the .dts[i] where it is enabled
Upside: Clean setup, only enabled sd_emmc_* have an alias
Downside: Much verbose patch(set)

Any preferences here? I honestly tend to 1. But this might break boards where
sd_emmc_a is not enabled, because the root device _will_ change in that case.

Best regards,
Alexander

sd_emmc_a is (almost?) always the iface used for SDIO devices, which are
not always present.

I would recommend we go with a single mapping in the top-level .dtsi

  SD card -> mmc0  (sd_emmc_b)
  eMMC    -> mmc1  (sd_emmc_c)
  SDIO    -> mmc2  (sd_emmc_a)

it's not exactly obvious why we don't go 0,1,2 == A,B,C but just
document it in the top-level .dtsi.

This approach also has the benefit of having the devices show up how
many/most boards showed up before the async probe changes.

https://patchwork.kernel.org/patch/11747669/

Commit message taken from commit 0011c6d18277 ("arm64: dts: rockchip: Assign a fixed index to mmc devices on rk3399 boards.")

The unconventional order (B, C, A) is due to the fact that sd_emmc_a is
(according to the comments) only used for SDIO.

AFAICS all boards either have both sd_emmc_b and sd_emmc_c or only one of
them enabled. So the alias order should match the previous non-async order
for all of them.

[PATCH v2 1/1] arm64: dts: amlogic: Assign a fixed index to mmc devices

[Alexander Stein]

Recently introduced async probe on mmc devices can shuffle block IDs.
Pin them to fixed values to ease booting in environments where UUIDs
are not practical. Use newly introduced aliases for mmcblk devices from [1].
[1]
https://patchwork.kernel.org/patch/11747669/

Commit message taken from commit 0011c6d18277 ("arm64: dts: rockchip: Assign a fixed index to mmc devices on rk3399 boards.")

The unconventional order (B, C, A) is due to the fact that sd_emmc_a is
(according to the comments) only used for SDIO.

AFAICS all boards either have both sd_emmc_b and sd_emmc_c or only one of
them enabled. So the alias order should match the previous non-async order
for all of them.

Just for the records, I only tested this on my ODROID-N2 (G12 based) board.

Thanks for updating this.

minor nit: as I suggested earlier, could you add comments here showing the
intention that mmc0 -> SD, mmc1 -> eMMC, mmc2 -> SDIO

Sorry for the delay.

I somehow missed this v3 at the end of the v5.12 cycle, but I've queued
it up for v5.13 now so it should get broader testing in linux-next now.

Was this patch [1] missed again by mistake? I can't find it in linux-next or 
anywhere else. [2] also shows that this commit is not referenced from any 
branch.
