2016-06-01	imx233: rewrite i2c driver	Amaury Pouly	1	-7/+63
	The new driver provides several new features: - asynchronous transfer - transactions (several transfers executed at once) - queueing The style still provides the legacy interface. Change-Id: I6d8ecc89d1f7057847c9b2dc69b76cd45c9c8407
2016-05-28	imx233: generate register headers using headergen_v2 and update code for it	Amaury Pouly	1	-6/+0
	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

2012-08-18	imx233: rework i2c driver to fix dma issues	Amaury Pouly	1	-1/+2
	There are tricky DMA/cache related issue on the imx233 which could pop up with the old driver. The new one ensures that all dma tranfers are cache safe by using an intermediate buffer. Change-Id: I72060682d1c285c83ae16455cfdb62f372b5d687

2012-03-15	imx233/fuze+: rework i2c and fmradio_i2c init	Amaury Pouly	1	-1/+1
	Only enable fmradio_i2c once with _init() called from system. Move actual i2c init to system for consistency. Move tuner power pin setup to power instead of fmradio. Change-Id: Idb56bfba5803f71b5d049f174c48d2afb969a6ea
2011-07-23	imx233/fuze+: huge rework	Amaury Pouly	1	-1/+1
	- enable MMU -rework lcd frame buffer - add rtc/adc/power stubs (or not) - fix a few MMC related defines (hopefully) - implement cache handling for DMA - more SD work - add keymap (based on clip) - add virtual buttons - update linker scripts - big step toward apps actually compiling git-svn-id: svn://svn.rockbox.org/rockbox/trunk@30200 a1c6a512-1295-4272-9138-f99709370657
