Michael Sevakis 292e7cab73 Gigabeat S: PMIC SPI improvement and bugfixes. 
Nick some aspects from the as3525 ascodec driver to improve throughput in
the beast's SPI communications by switching tranfer descriptors to the
caller's stack and getting rid of thread synchronization.

Fix a bug that suddenly became obvious that could permanently stall the SPI
driver because all data could be shifted out before the interrupt could get
serviced. In that case, it needs a kick to restart it. Should probably put
the SPI interrupt priority above DVFS.

A tweak to the event registration interface to simplify it.

ata-imx31.c Commit to certain names for cache coherency APIs and discard the aliases. 2011-12-17 07:27:24 +00:00
ata-target.h FS#12418 - Merge prototypes from ata-target.h files into new file ata-driver.h. After this change: 2011-12-08 21:23:53 +00:00
avic-imx31.c i.MX31: Simplify nested interrupt handling. Give SVC mode its own stack by grabbing the FIQ stack that's just been taking up space. Just get rid of all FIQ setup since it isn't used anyway. 2011-10-14 00:01:41 +00:00
avic-imx31.h i.MX31 avic: Fix super-stale comment. 2011-10-14 06:19:03 +00:00

dvfs_dptc-imx31.c Introduce USED_ATTR wrapper for __attribute__((used)). 2011-12-09 15:33:59 +00:00
dvfs_dptc-imx31.h i.MX31: Now that it matters because there's a debug screeen that allows changing things while running, some DVFS/DPTC stuff has to be done more carefully. Trim out some stuff and group functions better as well. 2011-01-23 20:21:35 +00:00

i2c-imx31.c Merge functionality of wakeups and semaphores-- fewer APIs and object types. semaphore_wait takes a timeout now so codecs and plugins have to be made incompatible. Don't make semaphores for targets not using them. 2011-03-02 08:49:38 +00:00
