[PATCH 05/15] mfd: db8500-prcmu: Register devices using the newly DT:ed MFD API

Lee Jones lee.jones at linaro.org
Wed Jun 20 08:56:41 EDT 2012


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.
