2011-05-20OMAP3: PM: Boot message is not an error, and not helpful, remove itSanjeev Premi

2011-05-20OMAP3: cpuidle: change the power domains modes determination logicJean Pihet
The achievable power modes of the power domains in cpuidle depends on the system wide 'enable_off_mode' knob in debugfs. Upon changing enable_off_mode, do not change the C-states 'valid' field but instead dynamically restrict the power modes when entering idle. The C-states 'valid' field is just used to enable/disable some C-states at init and shall not be changed later on.

2011-05-20OMAP3: cpuidle: code rework for improved readabilityJean Pihet
- fix single and multi-lines comments format - removed the omap3_idle_bm_check function and replaced the test in omap3_enter_idle_bm by the equivalent code - re-organize omap3_enter_idle_bm code path, assign local variables only when needed - reword some comments Signed-off-by: Jean Pihet <j-pihet@ti.com> Signed-off-by: Kevin Hilman <khilman@ti.com>
2011-05-20OMAP3: cpuidle: re-organize the C-states dataJean Pihet
The current implementation defines an internal structure and a C-states array. Using those structures is redundant to the structs used by the cpuidle framework. This patch provides a clean-up of the internal struct, removes the internal C-states array, stores the data using the existing cpuidle per C-state struct and registers the mach specific data to cpuidle C-state driver_data (accessed using cpuidle_[gs]et_statedata). Also removes unused macros, fields and code and compacts the repeating code using an inline helper function. The result is more compact and more readable code as well as reduced data RAM usage. Also retain C1 as the only always valid C-state and system safe state. Signed-off-by: Jean Pihet <j-pihet@ti.com> Signed-off-by: Kevin Hilman <khilman@ti.com>
2011-05-20OMAP3: clean-up mach specific cpuidle data structuresJean Pihet
- sleep_latency and wake_latency are not used, replace them by exit_latency which is used by cpuidle. exit_latency simply is the sum of sleep_latency and wake_latency, - replace threshold by target_residency, - changed the OMAP3 specific cpuidle code accordingly, - changed the OMAP3 board code accordingly.

2011-05-20OMAP3 cpuidle: remove useless SDP specific timingsJean Pihet
The cpuidle states settings can be overriden by some board- specific settings, by calling omap3_pm_init_cpuidle. Remove the 3430SDP specific states settings registration since the figures are identical to the default ones (in cpuidle34xx.c).

2011-05-20oprofile, x86: Enable preemption during pci device setup in IBS initRobert Richter
IBS initialization is a mix of per-core register access and per-node pci device setup. Register access should be pinned to the cpu, but pci setup must run with preemption enabled. This patch better separates the code into non-/preemptible sections and fixes sleeping with preemption disabled. See bug message below. Fixes also freeing the eilvt entry by introducing put_eilvt(). BUG: sleeping function called from invalid context at mm/slub.c:824 in_atomic(): 1, irqs_disabled(): 0, pid: 32357, name: modprobe INFO: lockdep is turned off.

2011-05-20[media] V4L: mt9m111: fix pixel clockTeresa Gámez
This camera driver supports only rising edge, which is the default setting of the device. The function mt9m111_setup_pixfmt() overwrites this setting. So the driver actually uses falling edge.

2011-05-20[media] V4L: soc-camera: avoid huge arrays, caused by changed format codesGuennadi Liakhovetski
Recently mediabus pixel format codes have become a part of the user- space API, at which time their values also have been changed from contiguous numbers, running from 0 to sparse numbers with values around 0x1000, 0x2000, 0x3000... This made them unsuitable for the use as array indices. This patch switches soc-camera internal format look-ups to not depend on values of those macros.

The EPWISR indicates that there are 4 interrupts sources, port1, port2, message unit and port write receive, but the sRIO driver does not support port2 for now, still the handler takes care of port2.
