There are drivers that are not disabling their clocks (gpio &
uart). These clocks need to be disabled if retention/off state is
wanted when idling. Before disabling them in idle loop this option
needs to be checked.

Fix DPLL jitter correction programming.  Previously,
omap3_noncore_dpll_program() stored the FREQSEL jitter correction
parameter to the wrong register.  This caused jitter correction to be set
incorrectly and also caused the DPLL divider to be programmed incorrectly.

Also, fix DPLL divider programming.  An off-by-one error existed in
omap3_noncore_dpll_program(), causing DPLLs to be programmed with a higher
divider than intended.

On OMAP3430ES2+, SSI has both an initiator standby CM_IDLEST bit, and a
target idle CM_IDLEST bit.  This is a departure from previous silicon,
which only had an initiator standby bit.

This means that omap2_clk_wait_ready() needs to wait for the SSI
module to indicate readiness after both SSI interface and functional
clocks are enabled.

On OMAP3430ES2, DSS has both an initiator standby CM_IDLEST bit, and a
target idle CM_IDLEST bit.  This is a departure from previous silicon,
which only had an initiator standby bit.

This means we need to test the target idle bit after enabling
dss1_alwon_fclk.  Previous clock code has done the wrong thing since ES2
came out: it's either tested the wrong bit, causing

    Clock dss1_alwon_fck failed to enable in 100000 tries

messages, or not tested anything at all, causing crashes during DISPC
initialization with:

    Unhandled fault: external abort on non-linefetch (0x1028)

This patch modifies omap2_clk_wait_ready() to wait for the DSS to become
accessible after dss1_alwon_fclk, dss_l3_iclk, and dss_l4_iclk are enabled.

Enable hardware save-and-restore for the CORE and USBHOST powerdomains
during PM layer initialization.  On OMAP3, this only affects the
USBTLL and USBHOST modules.

There is probably a sleep and wakeup latency penalty with these
enabled.  No one seems to have quantified it yet.  If the added
latency is measurable, an alternate approach would be to only enable
hardware save-and-restore if there are USB devices attached.

Remove usbhost_sar_fclk from the OMAP3 clock framework.  The bit that
the clock was tweaking doesn't actually enable or disable a clock; it
controls whether the hardware will save and restore USBHOST state
when the powerdomain changes state.  (That happens to coincidentally
enable a clock for the duration of the operation, hence the earlier
confusion.)

In place of the clock, mark the USBHOST powerdomain as supporting
hardware save-and-restore functionality.

OMAP3430ES2+ introduces a new feature: optional powerdomain context
hardware save-and-restore (SAR).  Currently, this feature only applies
to USBHOST and USBTLL module context when the USBHOST or CORE
powerdomains enter a low-power sleep state[1].  This feature avoids
re-enumeration of USB devices when the powerdomains return from idle,
which is potentially time-consuming.

This patch adds support for enabling and disabling hardware
save-and-restore to the powerdomain code.  Three new functions are
added, pwrdm_enable_hdwr_sar(), pwrdm_disable_hdwr_sar(), and
pwrdm_can_hdwr_sar().  A new struct powerdomain "flags" field is
added, with a PWRDM_HAS_HDWR_SAR flag to indicate powerdomains with
SAR support.

Thanks to Jouni Högander <jouni.hogander@nokia.com> for reviewing an
earlier version of these patches, and Richard Woodruff <r-woodruff2@ti.com>
for clarifying the purpose of these bits.

1.  For the USBHOST controller module, context loss occurs when the
    USBHOST powerdomain enters off-idle.  For USBTLL, context loss
    occurs either if CORE enters off-idle, or if the CORE logic is
    configured to turn off when CORE enters retention-idle (OSWR).
