Also, rename the cs5535-acpi clones to what we actually use for the (currently out-of-tree) SCI driver. In the process, that fixes a subtle bug in olpc-xo1.c which broke powerdown on XO-1s.. olpc-xo1-ac-acpi was a typo, not something that actually existed.

mfd: Add mfd_clone_cell(), convert cs5535-mfd/olpc-xo1 to it 2011-03-26T23:09:30+00:00 Andres Salomon dilinger@queued.net 2011-03-22T02:19:35+00:00 fa1df691688f34cbcd5bf77bd084bbe47e9d6bfe Replace mfd_shared_platform_driver_register with mfd_clone_cell. The former was called by an mfd client, and registered both a platform driver and device. The latter is called by an mfd driver, and registers only a platform device. The downside of this is that mfd drivers need to be modified whenever new clients are added that share a cell; the upside is that it fits Linux's driver model better. It's also simpler. This also converts cs5535-mfd/olpc-xo1 from the old API. cs5535-mfd now creates the olpc-xo1-{acpi,pms} devices, while olpc-xo1 binds to them via platform drivers.

mfd: Add sharing for cs5535 acpi/pms cells 2011-03-23T09:41:58+00:00 Andres Salomon dilinger@queued.net 2011-02-18T03:07:36+00:00 1310e6d638b302bd9cd064f8de7dcd546bb7f597 This enables sharing of cs5535-mfd cells via the new mfd_shared_* API. Hooks for enable/disble of resources are added, with refcounting of resources being automatically handled so that cs5535_mfd_res_enable/disable are only called when necessary. Clients of cs5535-mfd (in this case, olpc-xo1.c) are also modified to use the mfd_shared API. The platform drivers are also renamed to olpc-xo1-{pms,acpi}, and resource enabling/disabling is replaced with mfd_shared API calls.
