DMA: Split the APBH DMA init into block and channel init

2012-04-16T12:53:59Z

This fixes the issue where mxs_dma_init() was called either twice or never, without introducing any new init hooks. The idea is to allow each and every device using the APBH DMA block to configure and request only the channels it uses, instead of making it call init for all the channels as is now. The common DMA block init part, which only configures the block, is then called from CPUs arch_cpu_init() call.

i.MX28: Drop __naked function from spl_mem_init

2012-03-27T07:41:16Z

Instead of compiling the function and using the result as a constant, simply use the constant. NOTE: This patch works around bug: http://gcc.gnu.org/bugzilla/show_bug.cgi?id=52546 Signed-off-by: Marek Vasut Cc: Stefano Babic Cc: Tom Rini

i.MX28: Make the stabilization delays shorter

2012-03-27T07:41:16Z

Cut down the VDDIO/VDDA regulator stabilization delays to 500 uS. That should be enough according to the datasheet and bootlets. Signed-off-by: Marek Vasut Cc: Wolfgang Denk Cc: Detlev Zundel Cc: Stefano Babic Cc: Robert Deliën Cc: Fabio Estevam Cc: Matthias Fuchs
