This series adds DTS and defconfig support for the eMMC controller on
Black Sesame Technologies C1200 SoC, split from the v5 MMC series [1].

The MMC driver patches (dt-bindings, sdhci bounce buffer, BST SDHCI
driver, and MAINTAINERS update) were merged via mmc-next during the
v7.1 merge window and are now in mainline as of Linux 7.1-rc1 [2].
These remaining DTS and defconfig patches are submitted to the mailing
lists for review (per Krzysztof's feedback on v6 [3])

Both patches now carry Acked-by: Gordon Ge <gordon.ge@bst.ai> (BST
maintainer), collected from the v7 thread [4][5].

Changes since v7 [6]:
- Collected Acked-by: Gordon Ge <gordon.ge@bst.ai> on patch 1/2 [4]
- Collected Acked-by: Gordon Ge <gordon.ge@bst.ai> on patch 2/2 [5]
- Rebased onto v7.1-rc1
- No code changes

Changes since v6:
- Resend with corrected recipients: send to mailing lists for review
  first, not directly to soc@ (BST has a platform maintainer in
  MAINTAINERS), per Krzysztof's feedback [3].

Changes since v5:
- Patch 2 (defconfig): fix CONFIG_MMC_SDHCI_BST ordering to match
  Kconfig position (between CONFIG_MMC_SDHCI_TEGRA and
  CONFIG_MMC_SDHCI_F_SDH30), as pointed out by Krzysztof Kozlowski.
  Confirmed via savedefconfig.

Build/check on v7.1-rc1:
- arch/arm64 defconfig: clean (savedefconfig keeps CONFIG_MMC_SDHCI_BST
  at its Kconfig-ordered position; no diff in the MMC_SDHCI section)
- arch/arm64/boot/dts/bst/bstc1200-cdcu1.0-adas_4c2g.dtb: builds clean
  with W=1 and CHECK_DTBS=y (no new warnings)
- checkpatch.pl --strict: 0 errors, 0 warnings, 0 checks on both patches

Hi Arnd,

Gentle ping on this series. It has been about 5 weeks since v8 was posted.

The MMC driver patches from the original series were merged via mmc-next
in v7.1-rc1. These remaining 2 patches (DTS + defconfig) are still pending.

Both patches have Acked-by: Gordon Ge <gordon.ge@bst.ai>.

No code changes needed — still applies cleanly.

Would you be able to pick this up via soc tree?

Thanks,
Albert

This is not a patchset for soc tree. This is patchset for BST - you are
waiting on BST maintainers. I recommend reading soc maintainer profile
doc, it describes the process.

Best regards,
Krzysztof

What's odd here is that Albert authored and sent all the BST patches
so far, including the one that adds Gordon as the sole maintainer.
I merged these from patches in the initial merge and expected to
see future work get routed through Gordon.

Albert and Gordon, please figure out between yourselves how you
want to handle this in the future. You can both be listed as
maintainers if you want, but to make everybody's life easier,
make sure that only a person who is listed in the MAINTAINERS
files is responsible for collecting patches and forwarding
them to soc@lists.linux.dev for inclusion.

        Arnd

You sent it already three times within one hour. Please stop.

Apologies for the noise. Sending is stopped on my side and the root
cause is still under investigation. Please use the canonical v8 for
review:
