2016-05-28imx233: generate register headers using headergen_v2 and update code for itAmaury Pouly
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

2013-06-17imx233: normalise clkctrlAmaury Pouly
The clkctrl functions were becoming a mess. Normalise the names, get rid of the xtal derived as special case and use the same interface. Change-Id: Ib954a8d30a6bd691914b5e0d97774ec9fc560c50

2012-12-26imx233: fix potential hbus dividor settings + docAmaury Pouly
HBUS uses the same field for integer and fractional dividers, the choice is made by a bit. Make sure both are changed together, otherwise this could result in the wrong divider to be used and in HBUS freq to be too low or too high (very bad). Change-Id: I253d8eeee26c5038868b729c4f791511295a39f0
2012-08-31imx233: fix auto slow divisorAmaury Pouly
The divisor must be set only when auto-slow is disabled. Change-Id: I31ed94f43a7c9deb80275dc73f8e3c78463b54c0

2012-05-21imx233: enable PLL on startupAmaury Pouly
Implement PLL enabling/disable and unconditionally power the PLL on startup. This is needed at least on the Zen X-Fi2. Change-Id: Ib9ddfdeaf973cedded4b3586dd16aa95a61e78ba
2012-05-19imx233: fix clkctrl namingAmaury Pouly
Move to a more consistent naming convention like the other devices Change-Id: I4ddbbee27ee9f5ae775c5776592ec7ce02b30948
2012-02-28imx233: user __FIELD_SET to set the clock divisorsAmaury Pouly
The clock divisors must *NEVER* be 0, first clearing then setting is thus undefined. Change-Id: Iba8e6ba1e668bf746e3f7387f0175f63d81f6b2b
