The patch titled
lxfb: clean up register definitions
has been removed from the -mm tree. Its filename was
lxfb-clean-up-register-definitions.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: lxfb: clean up register definitions
From: Andres Salomon <dilinger@xxxxxxxxxx>
- Rename various bitfield defines to match the data sheet names.
- Rename DF_ register definitions to VP_ to match the data sheet;
ie, DF_PAR -> VP_PAR.
- for GP/DC registers, rather than defining to specific addresses, use
an enum to number them sequentially and just multiply by 4 (bytes) to
access them (in read_*/write_* functions).
- for VP/FP registers, use an enum and multiple by 8 (bytes). They're
64bit registers.
