[Roman Volkov]

From: Roman Volkov <rvolkov@v1ros.org>

This patch set enables SD controller support for WM8650 and
fixes minor errors in WM8505 Device Tree file.

Changes in v3:
1. Add minor fixes for WM8505 SDHC node

Tested on both WM8505 and WM8650.

Hi maintainers, I see my previous versions were not applied. Could this
little patch set be applied for the linux-next? I don't think this is new
functionality, this must be considered as bugfix for existing Device Tree.

Any other suggestions?

[PATCH v3 RESEND 1/2] dts: vt8500: Add SDHC node to DTS file for WM8650

[Roman Volkov]

From: Roman Volkov <rvolkov@v1ros.org>

Since WM8650 has the same 'WMT' SDHC controller as WM8505, and the driver
is already in the kernel, this node enables the controller support for
WM8650

[PATCH v3 RESEND 2/2] dts: vt8500: Fix errors in SDHC node for WM8505

[Roman Volkov]

From: Roman Volkov <rvolkov@v1ros.org>

According to datasheet, the registers space of SDHC controller is 1Kb,
not '0x1000', the correct value should be '0x400'. Bracket interrupt
numbers individually per recommendations.

Applied both to next/dt, thanks a lot for following up!

Let me know if you think this should go into stable backports as well,
I did not apply it to the fixes branch as you don't have a
'Cc: stable@vger.kernel.org' tag and it has never worked so far.

Yes, this must go into the stable too. Let me know if I must change
something or resend.

I can put them in the fixes branch with the appropriate stable
tag myself, but please clarify whether we need just the first or
both patches there. It looks to me that the second one while
correct only addresses a cosmetic problem and everything works
without it.

Correct, everything works without the second one. One of reviewers
noticed that addresses are different between WM8505 and WM8650 where
the hardware is the same. If such trivial changes are not accepted,
please do not apply.

Happy New Year,
Roman
