Could you help to review it and give some comments or ACK.
Thank you very much.



Best regards,

Subject: Re: [v12, 0/8] Fix eSDHC host version register bug

This patchset is used to fix a host version register bug in the
T4240-R1.0-R2.0 eSDHC controller. To match the SoC version and
revision, 10 previous version patchsets had tried many methods but all

of them were rejected by reviewers.

quoted

Such as
        - dts compatible method
        - syscon method
        - ifdef PPC method
        - GUTS driver getting SVR method Anrd suggested a
soc_device_match method in v10, and this is the only available method
left now. This v11 patchset introduces the soc_device_match interface
in soc driver.

The first six patches of Yangbo are to add the GUTS driver. This is
used to register a soc device which contain soc version and revision

information.

quoted

The other two patches introduce the soc_device_match method in soc
driver and apply it on esdhc driver to fix this bug.

This looks good to me! I am not sure which tree you want this to be
picked up through, but unless no other volunteers I can take it through
my mmc tree.

Although, before considering to apply, I need an ack from Scott/Arnd for
the guts driver in patch 5/8 and I need an ack from Greg for patch 7/8,
where the soc_device_match() interface is added (seems like you didn't
add him on cc/to).

Kind regards
Uffe
