Subject: [PATCH 0/1] OMAP: DMA: Attribution necessary only if the ch is not chained.
Date: Sat, 24 Nov 2007 18:29:34 -0400 [thread overview]
Message-ID: <4748A5CE.7080602@indt.org.br> (raw)
Hi Anand and folks,
Since the merging of linux-omap tree with linus tree, I'm facing a problem with MMC multislot support on N800 boards, that stops working.
Well, after investigating recent modifications on DMA, I was verifying Anand Gadiyar' patch 'OMAP: DMA: Added support for DMA chaining' and I realize a line of this patch is the source of the problem.
Apparently, the attribution
+ status = OMAP_DMA_CSR_REG(ch);
is necessary only if the ch is not chained.
Tested on N800 with MMC multislot support and works fine again.
BR,
Carlos.
