[PATCH 05/15] mfd: db8500-prcmu: Register devices using the newly DT:ed MFD API
From: Lee Jones <hidden>
Date: 2012-06-20 12:56:41
Subsystem:
arm/nomadik/ux500 architectures, multifunction devices (mfd), the rest, voltage and current regulator framework · Maintainers:
Linus Walleij, Lee Jones, Linus Torvalds, Liam Girdwood, Mark Brown
Now the MFD API is Device Tree aware we can use it for platform registration again, even when booting with DT enabled. To aid in Device Node pointer allocation we provide each cell with the associative compatible string.
