2009-06-16V4L/DVB (11607): soc-camera: add a free_bus method to struct soc_camera_linkGuennadi Liakhovetski
Currently pcm990 camera bus-width management functions request a GPIO and never free it again. With this approach the GPIO extender driver cannot be unloaded once camera drivers have been loaded, also unloading theb i2c-pxa bus driver produces errors, because the GPIO extender driver cannot unregister properly. Another problem is, that if camera drivers are once loaded before the GPIO extender driver, the platform code marks the GPIO unavailable and only a reboot helps to recover. Adding an explicit free_bus method and using it in mt9m001 and mt9v022 drivers fixes these problems.

2009-06-05[ARM] pxa: add vcc_core regulation for cpufreq on pxa2xxRobert Jarzmik
Add voltage regulation capability to pxa2xx cpufreq driver. The cpufreq will ask for a "vcc_core" regulator to the regulator framework. If a regulator is found at probe time, it will be used with values specified in PXA270 Electrical, Mechanical, and Thermal Specifications. If not, it will be assumed for now that frequency change will work without voltage control. This assumes that the IPL/SPL installs sane values to an existing voltage regulator (ie. voltage high enough to support the full range).

2009-06-05[ARM] pxa: allow IRQ_BOARD_END to be customized and make zylonite to use itPhilipp Zabel
The default value is 16 IRQs. Zylonite needs 32, ASIC3 based boards need 70. My problem is still that due to the way IRQ_GPIO is hardcoded, ASIC3 based boards need 70 IRQs starting at IRQ_BOARD_START. If I define ASIC3 IRQs similar to LoCoMo or SA1111, things break as soon as something selects PXA_HAVE_BOARD_IRQS. Increasing the default number of board IRQs to 70 instead doesn't seem very nice.

2009-06-03rfkill: rewriteJohannes Berg
This patch completely rewrites the rfkill core to address the following deficiencies: * all rfkill drivers need to implement polling where necessary rather than having one central implementation * updating the rfkill state cannot be done from arbitrary contexts, forcing drivers to use schedule_work and requiring lots of code * rfkill drivers need to keep track of soft/hard blocked internally -- the core should do this * the rfkill API has many unexpected quirks, for example being asymmetric wrt. alloc/free and register/unregister * rfkill can call back into a driver from within a function the driver called -- this is prone to deadlocks and generally should be avoided * rfkill-input pointlessly is a separate module * drivers need to #ifdef rfkill functions (unless they want to depend on or select RFKILL) -- rfkill should provide inlines that do nothing if it isn't compiled in * the rfkill structure is not opaque -- drivers need to initialise it correctly (lots of sanity checking code required) -- instead force drivers to pass the right variables to rfkill_alloc() * the documentation is hard to read because it always assumes the reader is completely clueless and contains way TOO MANY CAPS * the rfkill code needlessly uses a lot of locks and atomic operations in locked sections * fix LED trigger to actually change the LED when the radio state changes -- this wasn't done before Tested-by: Alan Jenkins <alan-jenkins@tuffmail.co.uk> Signed-off-by: Henrique de Moraes Holschuh <hmh@hmh.eng.br> [thinkpad] Signed-off-by: Johannes Berg <johannes@sipsolutions.net> Signed-off-by: John W.
