ARM: OMAP2+: am33xx: Make am33xx as a separate class
Initially, we decided to make am33xx family of device to fall
under omap3 class (cpu_is_omap34xx() = true), since it carries
Cortex-A8 core. But while adding complete baseport support
(like, clock, power and hwmod) support, it is observed that,
we are creating more and more problems by treating am33xx device
as omap3 family, as nothing matches between them
(except cortex-A8 mpu).
So, after long discussion we have came to the conclusion that,
we should not consider am33xx device as omap3 family, instead
create separate class (SOC_AM33XX) under OMAP2PLUS.
This means, for am33xx device, cpu_is_omap34xx() will return false,
and only cpu_is_am33xx() will be true.

ARM: OMAP2+: am33xx: Make am33xx as a separate class
Initially, we decided to make am33xx family of device to fall
under omap3 class (cpu_is_omap34xx() = true), since it carries
Cortex-A8 core. But while adding complete baseport support
(like, clock, power and hwmod) support, it is observed that,
we are creating more and more problems by treating am33xx device
as omap3 family, as nothing matches between them
(except cortex-A8 mpu).
So, after long discussion we have came to the conclusion that,
we should not consider am33xx device as omap3 family, instead
create separate class (SOC_AM33XX) under OMAP2PLUS.
This means, for am33xx device, cpu_is_omap34xx() will return false,
and only cpu_is_am33xx() will be true.

ARM: OMAP3: PM: fix I/O wakeup and I/O chain clock control detection
The way that we detect which OMAP3 chips support I/O wakeup and
software I/O chain clock control is broken.
Currently, I/O wakeup is marked as present for all OMAP3 SoCs other
than the AM3505/3517. The TI81xx family of SoCs are at present
considered to be OMAP3 SoCs, but don't support I/O wakeup. To resolve
this, convert the existing blacklist approach to an explicit,
whitelist support, in which only SoCs which are known to support I/O
wakeup are listed. (At present, this only includes OMAP34xx,
OMAP3503, OMAP3515, OMAP3525, OMAP3530, and OMAP36xx.)
Also, the current code incorrectly detects the presence of a
software-controllable I/O chain clock on several chips that don't
support it. This results in writes to reserved bitfields, unnecessary
delays, and console messages on kernels running on those chips:
http://www.spinics.net/lists/linux-omap/msg58735.html
Convert this test to a feature test with a chip-by-chip whitelist.
Thanks to Dave Hylands <dhylands@gmail.com> for reporting this problem
and doing some testing to help isolate the cause. Thanks to Steve
Sakoman <sakoman@gmail.com> for catching a bug in the first version of
this patch. Thanks to Russell King <linux@arm.linux.org.uk> for
