Subject: [PATCH 0/7] dmaengine: mmp_tdma: Make the driver actually work
Hi,
chained to this message is a couple of improvements to the MMP Audio DMA
driver (mmp_tdma). Please consider applying them.
Patches 1 to 5 are various improvements robustness and error handling.
The most important patch is [PATCH 6/7], which makes the driver play
along with soc-generic-dmaengine-pcm. This is necessary to play sound on
devicetree-based MMP2 machines.
The last patch drops MMP_SRAM dependency. This is a safe thing to do,
because nothing currently actually uses this (mmp_tdma) driver. There's a
redundant driver in sound/soc/pxa/mmp-pcm.c, which is also effectively
unused. Sigh.
Tested on an OLPC XO-1.75 laptop (along with changes to the MMP SSPA
driver).
Thank you
Lubo
