Subject: [PATCH] it821x: fix incorrect SWDMA mask
Date: Tue, 3 Jul 2007 01:45:59 +0200 [thread overview]
Message-ID: <200707030145.59287.bzolnier@gmail.com> (raw)
SWDMA modes are unsupported by it821x. Attempts to tune SWDMA modes always
fail (due to sanity check in ->speedproc) and result in PIO being tuned.
* Fix incorrect SWDMA mask so core code won't try these modes and will just
tune PIO if no other DMA modes are available.
* Bump driver version.
