The patch titled
regulator: machine driver interface
has been removed from the -mm tree. Its filename was
regulator-machine-driver-interface.patch
This patch was dropped because it was merged into mainline or a subsystem tree
The current -mm tree may be found at http://userweb.kernel.org/~akpm/mmotm/
------------------------------------------------------
Subject: regulator: machine driver interface
From: Liam Girdwood <lg@xxxxxxxxxxxxxxxxxxxxxxxxxxx>
This interface is for machine specific code and allows the creation of
voltage/current domains (with constraints) for each regulator. It can provide
regulator constraints that will prevent device damage through over voltage or
over current caused by buggy client drivers. It also allows the creation of a
regulator tree whereby some regulators are supplied by others (similar to a
clock tree).
