ARM: OMAP2+ i2c NACK without STP
On OMAP4 OMAP_I2C_STAT_NACK is causing a timeout on the next access.
The isr cleans all flags in OMAP_I2C_CON_REG by setting OMAP_I2C_CON_STP
OMAP_I2C_CON_STP is also set in omap_i2c_xfer_msg on the last message.
According to the TI TSR the sequence for OMAP_I2C_STAT_NACK and

Sometimes, bootloaders starts up with a frequency which is not

After this condition, the first call to omap_target results in the
following:
omap_getspeed(actual device frequency) != policy->cur(frequency that
cpufreq thinks that the system is at), and it is possible that
freqs.old == freqs.new (because the governor requested a scale down).
We exit without triggering the notifiers in the current code, which
does'nt let code which depends on cpufreq_notify_transition to have
accurate information as to what the system frequency is.
Instead, we do a normal transition if policy->cur is wrong, then,

actual new cpu frequency and all required notifiers have the accurate

ARM: OMAP2+: hwmod: Add a new flag to handle hwmods left enabled at init
An hwmod with a 'HWMOD_INIT_NO_IDLE' flag set, is left in
enabled state by the hwmod framework post the initial setup.
Once a real user of the device (a driver) tries to enable it
at a later point, the hwmod framework throws a WARN() about
the device being already in enabled state.
Fix this by introducing a new internal flag '_HWMOD_SKIP_ENABLE' to
identify such devices/hwmods. When the device/hwmod is requested to be
enabled (the first time) by its driver/user, nothing except the
mux-enable is needed. The mux data is board specific and is
unavailable during initial enable() of the device, done by the
framework as part of setup().
A good example of a such a device is an UART used as debug console.
The UART module needs to be kept enabled through the boot, until the
UART driver takes control of it, for debug prints to appear on
the console.

ARM: OMAP: PRCM: add suspend prepare / finish support
PRCM chain handler needs to disable forwarding of interrupts during
suspend, because runtime PM is disabled and most of the drivers
are potentially not able to handle interrupts coming at this time.
This patch masks all the PRCM interrupt events if a PRCM interrupt
occurs during suspend, but does not ack them. Once suspend finish
is called, all the masked events will be re-enabled, which causes
immediate PRCM interrupt and handles the postponed event.
The suspend prepare and complete callbacks will be called from

The functions defined in this patch should eventually be moved to
suspend->prepare and suspend->finish driver hooks, once the PRCM

ARM: OMAP: PRCM: add support for chain interrupt handler
Introduce a chained interrupt handler mechanism for the PRCM
interrupt, so that individual PRCM event can cleanly be handled by

names, which are then matched to the particular PRCM interrupt bit
depending on the specific OMAP SoC being used.
PRCM interrupts have two priority levels, high or normal. High priority
is needed for IO event handling, so that we can be sure that IO events
are processed before other events. This reduces latency for IO event
customers and also prevents incorrect ack sequence on OMAP3.

ARM: OMAP: hwmod data: fix iva and mailbox hwmods for OMAP 3
Seems the commit 7e89098 was overly aggressive in adding iva and mailbox
hwmods so now they are registered twice.

ARM: unwinder: fix bisection to find origin in .idx section
The bisection implemented in unwind_find_origin() stopped to early. If
there is only a single entry left to check the original code just took
the end point as origin which might be wrong.
This was introduced in commit
de66a979012d ("ARM: 7187/1: fix unwinding
for XIP kernels").
