OMAP2+: voltage: reorganize, split code from data
This is a first pass at reorganizing mach-omap2/voltage.c:
- Separate almost all of the data from the code of mach-omap2/voltage.c.
The code remains in mach-omap2/voltage.c. The data goes into one
of several places, depending on what type of data it is:
- Silicon process/validation data: mach-omap2/opp*_data.c
- VC (Voltage Controller) data: mach-omap2/vc*_data.c
- VP (Voltage Processor) data: mach-omap2/vp*_data.c
- Voltage domain data: mach-omap2/voltagedomains*_data.c
The ultimate goal is for all this data to be autogenerated, the same
way we autogenerate the rest of our data.
- Separate VC and VP common data from VDD-specific VC and VP data.
- Separate common voltage.c code from SoC-specific code; reuse common code.
- Reorganize structures to avoid unnecessary memory loss due to unpacked
fields.
There is much left to be done. VC code and VP code should be separated out
into vc*.c and vp*.c files. Many fields in the existing structures are
superfluous, and should be removed. Some code in voltage.c seems to be
duplicated; that code should be moved into functions of its own. Proper
voltage domain code should be created, as was done with the powerdomain
and clockdomains, and powerdomains should reference voltagedomains.

OMAP2/3: VENC hwmod: add OCPIF_SWSUP_IDLE flag to interface
According to the hwmod interface data, the DSS submodule "VENC" uses a
clock, "dss_54m_fck"/"dss_tv_fck", which the PRCM cannot autoidle. By
default, the hwmod code assumes that interface clocks can be autoidled
by the PRCM. When the interface clock can't be autoidled by the PRCM,
those interfaces must be marked with the OCPIF_SWSUP_IDLE flag.
Otherwise, the "interface clock" will always have a non-zero use
count, and the device won't enter idle. This problem was observed on
N8x0.
Fix the immediate problem by marking the VENC interface with the
OCPIF_SWSUP_IDLE flag. But it's not clear that
"dss_54m_fck"/"dss_tv_fck" is really the correct interface clock for
VENC. It may be that the VENC interface should use a
hardware-autoidling interface clock. This is the situation on OMAP4,
which uses "l3_div_ck" as the VENC interface clock, which can be
autoidled by the PRCM. Clarification from TI is needed.

OMAP2xxx: clock: remove dsp_irate_ick

81b34fbecbfbf24ed95c2d80d5cb14149652408f ("OMAP2 clock:
split OMAP2420, OMAP2430 clock data into their own files"), it's
possible to remove dsp_irate_ick from the OMAP2420 and OMAP2430 clock

OMAP2xxx: clock: fix interface clocks and clockdomains for modules in the WKUP domain
The parent of the interface clocks for GPTIMER1, MPU_WDT,
SYNCTIMER_32K, SCM, WDT1, and the ICR (2430 only) were all listed as
being l4_ck. This isn't accurate; these modules exist inside the WKUP
domain, and the interface clock to these modules runs at the SYS_CLK
rate rather than the CORE L4 rate.
So, create a new clock "wu_l4_ick", similar to the OMAP3
"wkup_l4_ick", that serves as the parent for these clocks.
Also, these clocks were listed as existing inside core_l4_clkdm;
wkup_clkdm is probably more accurate.

omap: mmc: split out init for 2420
The MMC controller on the OMAP2420 is different from those
on the OMAP2430, OMAP3 and OMAP4 families - all of the latter
are identical. The one on the OMAP2420 is closer to that
on OMAP1 chips.
Currently, the n8x0 is the only OMAP2420 platform supported
in mainline which registers the MMC controller. Upcoming
changes to register the controllers using hwmod data are
potentially invasive. To reduce the risk, separate out the
2420 controller registration from the common init function
and update its only user. Also seperating out mux settings
for OMAP2420.

Several ACPI drivers fail to build if CONFIG_NET is unset, because
