2010-05-20OMAP2+ clock: clean up clkt_clksel.cPaul Walmsley
This patch cleans up arch/arm/mach-omap2/clkt_clksel.c. It: - makes several functions static that are not called outside the file; - adds documentation; - makes some code paths easier to read (hopefully), by breaking up compound statements and removing redundant checks; - converts some pr_err()s that indicate clock tree data problems into WARN()s, so they are more likely to be noticed; - and moves omap2_clk_round_rate() back into mach-omap2/clock.c, its proper home, since it is not clksel-specific.

2010-05-20OMAP2+ clock: remove DEFAULT_RATE clksel_rate flagPaul Walmsley
The DEFAULT_RATE clksel_rate flag is essentially useless. It was set on some of the lowest divisors, which, when switching to a much higher-rate parent, could have potentially resulted in rates that exceeded the hardware specifications for downstream clocks in the window between the clk_set_parent(), and a subsequent clk_set_rate(). It seems much safer to just remove the flag and always use the highest available divisor (resulting in the lowest possible rate) after the switch, and this patch does so. Ideally, it would be best to first attempt to switch to a divisor that matches the clock's rate with the previous parent, if at all possible. But that is a project for some other day or some other person. The parent changing code is rarely used. Signed-off-by: Paul Walmsley <paul@pwsan.com>

Writes to the PM_*GRPSEL registers should use _GRPSEL_ macros, not _EN_ macros, to match the TRM and guard against inadvertent error. This patch should not cause any functional change.

2010-05-20OMAP2+ PRCM: convert remaining PRCM macros to the _SHIFT/_MASK suffixesPaul Walmsley
Fix all of the remaining PRCM register shift/bitmask macros that did not use the _SHIFT/_MASK suffixes to use them. This makes the use of these macros consistent. It is intended to reduce error, as code can be inspected visually by reviewers to ensure that bitshifts and bitmasks are used in the appropriate places.

2010-05-20AM3517: rename the i2c boardinfo to make it more readablestanley.miao
There are three i2c buses on am3517, and each i2c bus has several devices on it, so we can't name the i2c boardinfo structures with one of these devices. In order to make it more readable, now rename these three boardinfo structures based on i2c indexes.

2010-05-20OMAP2/3/4: DMA: disable channel interrupts in omap_init_dma()Mika Westerberg
If we are softbooting another kernel using kexec, DMA controller state is not known when we are performing omap_init_dma(). It is possible that some DMA channels are already active. For example after kexec we get: <4>IRQ 0020 for non-allocated DMAchannel 5 <4>IRQ 0020 for non-allocated DMAchannel 5 <4>IRQ 0020 for non-allocated DMAchannel 5 <4>IRQ 0020 for non-allocated DMAchannel 5 <4>IRQ 0020 for non-allocated DMAchannel 5 To prevent any weird things happening, we disable all channel interrupts during init.

2010-05-20omap: rx51: Change the TWL4030 VMMC2 voltage constraints andsupply nameJarkko Nikula
I believe the VMMC2 constraints must be the same than with VAUX3. Older boards are using TWL4030 VMMC2 supply for internal MMC whereas newer are using VAUX3 that has more limited constraints defined in this same file. More over, the VMMC2 supply is used also for analog audio domain and the miminum analog voltage of the TLV320AIC34 codec is 2.7 V. To combine these two facts, the patch changes supply name to V28_A as the newer boards register VMMC2_30 for VAUX3 and uses the same constraints than VAUX3 since those constraints are ok for the TLV320AIC34.
