From 8a686bc984454c1eba6788d0d97dec72ad87f052 Mon Sep 17 00:00:00 2001 From: Sergei Shtylyov Date: Sun, 11 Mar 2012 22:25:30 +0300 Subject: [PATCH] pata_cmd64x: use interrupt status from MRDMODE register Start using faster version of the bmdma_stop() method for the PCI0646U and newer chips that have the duplicate interrupt status bits in the I/O mapped MRDMODE register. Use the old, slow bmdma_stop() method on the older chips, taking into account that the interrupt bits are not coupled to DMA and that's enough to read the register to clear the interrupt (on the older chips). Determine what method to use at the driver load time. Fix kernel-doc of the bmdma_stop() methods, while at it.
