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
