2012-08-15[media] rename drivers/media/video as .../platformMauro Carvalho Chehab1-1514/+0
The remaining drivers are mostly platform drivers. Name the dir to reflect it. It makes sense to latter break it into a few other dirs. Signed-off-by: Mauro Carvalho Chehab <mchehab@redhat.com>
2012-07-30[media] via-camera: pass correct format settings to sensorDaniel Drake1-1/+1
The code attempts to maintain a "user format" and a "sensor format", but in this case it looks like a typo is passing the user format down to the sensor. This was preventing display of video at anything other than 640x480. Signed-off-by: Daniel Drake <dsd@laptop.org> Signed-off-by: Mauro Carvalho Chehab <mchehab@redhat.com>
2012-05-14[media] via-camera: specify XO-1.5 camera clock speedDaniel Drake1-2/+13
For the ov7670 camera to return images at the requested frame rate, it needs to make calculations based on the clock speed, which is a completely external factor (depends on the wiring of the system). On the XO-1.5, which is the only known via-camera user, the camera is clocked at 90MHz. Pass this information to the ov7670 driver, to fix an issue where a framerate of 3x the requested amount was being provided.

2012-01-13module_param: make bool parameters really bool (drivers & misc)Rusty Russell1-2/+2
module_param(bool) used to counter-intuitively take an int. In fddd5201 (mid-2009) we allowed bool or int/unsigned int using a messy trick. It's time to remove the int/unsigned int option. For this version it'll simply give a warning, but it'll break next kernel version. Acked-by: Mauro Carvalho Chehab <mchehab@redhat.com> Signed-off-by: Rusty Russell <rusty@rustcorp.com.au>
2012-01-10[media] convert drivers/media/* to use module_platform_driver()Axel Lin1-11/+1
This patch converts the drivers in drivers/media/* to use the module_platform_driver() macro which makes the code smaller and a bit simpler.

2011-11-07[media] via-camera: disable RGB modeDaniel Drake1-7/+3
The RGB mode does not work correctly. It captures fine at 640x480 but whenever the scaling engine is used to produce another resolution, color corruption occurs (lots of erroneous pink and green). It is not clear how the scaling engine is supposed to work and how it knows which pixel format it is dealing with. Work around this problem by disabling RGB support. YUYV scaling works just fine.

2011-09-11[media] [Resend] viacam: Don't explode if pci_find_bus() returns NULLJesper Juhl1-0/+2
In the unlikely case that pci_find_bus() should return NULL viacam_serial_is_enabled() is going to dereference a NULL pointer and blow up. Better safe than sorry, so be defensive and check the pointer.

2011-03-22[media] via-camera: Fix OLPC serial checkDaniel Drake1-46/+37
The code that checks the OLPC serial port is never built at the moment, because CONFIG_OLPC_XO_1_5 doesn't exist and probably won't be added. Fix it so that it gets compiled in, only executes on OLPC laptops, and move the check into the probe routine. The compiler is smart enough to eliminate this code when CONFIG_OLPC=n (due to machine_is_olpc() always returning false).
