3630 is getting treated like next rev of 3430
omap_chip.oc variable has to be updated for 3630 version
Otherwise the Core power domain is not getting registered.
This gets used in the registration of power domains in:
"arch/arm/mach-omap2/powerdomains34xx.h"
core_34xx_es3_1_pwrdm
OMAP_CHIP_INIT(CHIP_GE_OMAP3430ES3_1)
Core power doman will get registered for 3630 only when .oc is
populated correctly.
Tested on Zoom3(3630) board

OMAP3630 is the latest in the family of OMAP3 devices
and among the changes it introduces are:
New OPP levels for new voltage and frequency levels. a bunch of
Bug fixes to various modules feature additions, notably with ISP,
sDMA etc.
Details about the chip is available here:
http://focus.ti.com/general/docs/wtbu/wtbuproductcontent.tsp?templateId=6123&navigationId=12836&contentId=52606
Strategy used:
Strategy to introduce this device into Linux was discussed here:
Ref: http://marc.info/?t=125343303400003&r=1&w=2
Two approaches were available:
a) Consider 3630 generation of devices as a new family of silicon
b) Consider 3630 as an offshoot of 3430 family of devices
As a common consensus, (b) seems to be more valid for 3630 as:
* There are changes which are easily handled by using "FEATURES"
infrastructure.
For details how to do this, see thread:
http://marc.info/?t=125050998500001&r=1&w=2
* Most of existing 34xx infrastructure can be reused(almost 90%+)
- so no ugly if (cpu_is_omap34xx() || cpu_is_omap36xx())
all over the place
- lesser chance of bugs due to reuse of proven code flow
- 36xx specific handling can still be done where required
within the existing infrastructure
NOTE:
* If additional 34xx series are added, OMAP3430_REV_ESXXXX can be
added on top of the existing 3630 ones are renumbered
This patch was tested on SDP3430, boot tested on 3630 platform using
3430sdp defconfig

Add runtime check for these OMAP35x variations
based on the detected Si features:
OMAP3503, OMAP3515, OMAP3525 and OMA3530.
Also, delayed the call to pr_info() into actual
variant is detected in omap3_cpuinfo()

The OMAP35x family has multiple variants differing
in the HW features. This patch detects these features
at runtime and prints information during the boot.
Since most of the code seemed repetitive, macros
have been used for readability.

Move the remaining headers under plat-omap/include/mach
to plat-omap/include/plat. Also search and replace the
files using these headers to include using the right path.
This was done with:
#!/bin/bash
mach_dir_old="arch/arm/plat-omap/include/mach"
plat_dir_new="arch/arm/plat-omap/include/plat"
headers=$(cd $mach_dir_old && ls *.h)
omap_dirs="arch/arm/*omap*/ \
drivers/video/omap \
sound/soc/omap"
other_files="drivers/leds/leds-ams-delta.c \
drivers/mfd/menelaus.c \
drivers/mfd/twl4030-core.c \
drivers/mtd/nand/ams-delta.c"
for header in $headers; do
old="#include <mach\/$header"
new="#include <plat\/$header"
for dir in $omap_dirs; do
find $dir -type f -name \*.[chS] | \
xargs sed -i "s/$old/$new/"
done
find drivers/ -type f -name \*omap*.[chS] | \
xargs sed -i "s/$old/$new/"
for file in $other_files; do
sed -i "s/$old/$new/" $file
done
done
for header in $(ls $mach_dir_old/*.h); do
git mv $header $plat_dir_new/
done
