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?
2.3.1
From: Roman Volkov <[email protected]>
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

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.
