2016-05-28imx233: generate register headers using headergen_v2 and update code for itAmaury Pouly1-2/+2
NOTE: this commit does not introduce any change, ideally even the binary should be almost the same. I checked the disassembly by hand and there are only a few differences here and there, mostly the compiler decides to compile very close expressions slightly differently. I tried to run the new code on several targets to make sure and saw no difference. The major syntax changes of the new headers are as follows: - BF_{WR,SET,CLR} are now superpowerful and allows to set several fileds at once: BF_WR(reg, field1(value1), field2(value2), ...) - BF_CS (use like BF_WR) does a write to reg_CLR and then reg_SET instead of RMW - there is no more need for macros like BF_{WR_,SET,CLR}_V, since one can simply BF_WR with field_V(name) - the old BF_SETV macro has no trivial equivalent and is replaced with its its equivalent for BF_WR(reg_SET, ...) I also rename the register headers: "regs/regs-x.h" -> "regs/x.h" to avoid the redundant "regs". Final note: the registers were generated using the following command: ./headergen_v2 -g imx -o ../../firmware/target/arm/imx233/regs/ desc/regs-stmp3{600,700,780}.xml Change-Id: I7485e8b4315a0929a8edb63e7fa1edcaa54b1edc

2013-06-18imx233: implement recording side of pcmAmaury Pouly1-27/+172
Although everything is implemented, recording still doesn't work, dma is stuck. Add code for reference until this get a proper fix. Change-Id: Ifc016b00876230c6d337a5cd4f8bb90b856efac8

2012-05-20imx233: make sure dma descriptors are cache friendlyAmaury Pouly1-5/+14
Because DMA descriptors needs to be committed and discarded from the cache, if they are not cache aligned and/or if their size is not a multiple of cache ligne, nasty side effects could occur with adjacents data. The same applies to DMA buffers which are still potentially broken. Add a macro to ensure that these constraints will not break by error in the future.

2012-05-19imx233: move icoll stuff to its own fileAmaury Pouly1-2/+2
The icoll code now has an IRQ storm detection mechanism which will prevent the device from hard freezing in case it happen. Change-Id: I9861238dce61d29af1e48f9c534ec63a7f23465c
2012-03-03Revise the PCM callback system after adding multichannel audio.Michael Sevakis1-5/+4
Additional status callback is added to pcm_play/rec_data instead of using a special function to set it. Status includes DMA error reporting to the status callback. Playback and recording callback become more alike except playback uses "const void **addr" (because the data should not be altered) and recording uses "void **addr". "const" is put in place throughout where appropriate. Most changes are fairly trivial. One that should be checked in particular because it isn't so much is telechips, if anyone cares to bother. PP5002 is not so trivial either but that tested as working.
