[media] omap3isp: Refactor device configuration structs for Device Tree

2015-04-02T19:41:01+00:00

Make omap3isp configuration data structures more suitable for consumption by the DT by separating the I2C bus information of all the sub-devices in a group and the ISP bus information from each other. The ISP bus information is made a pointer instead of being directly embedded in the struct. In the case of the DT only the sensor specific information on the ISP bus configuration is retained. The structs are renamed to reflect that. After this change the structs needed to describe device configuration can be allocated and accessed separately without those needed only in the case of platform data. The platform data related structs can be later removed once the support for platform data can be removed.

[media] v4l2-subdev: add support for the new enum_frame_size 'which' field

2015-03-23T18:48:55+00:00

Support the new 'which' field in the enum_frame_size ops. Most drivers do not need to be changed since they always returns the same enumeration regardless of the 'which' field.

[media] v4l2-subdev: replace v4l2_subdev_fh by v4l2_subdev_pad_config

2015-03-23T18:41:36+00:00

If a subdevice pad op is called from a bridge driver, then there is no v4l2_subdev_fh struct that can be passed to the subdevice. This made it hard to use such subdevs from a bridge driver. This patch replaces the v4l2_subdev_fh pointer by a v4l2_subdev_pad_config pointer in the pad ops. This allows bridge drivers to use the various try_ pad ops by creating a v4l2_subdev_pad_config struct and passing it along to the pad op. The v4l2_subdev_get_try_* macros had to be changed because of this, so I also took the opportunity to use the full name of the v4l2_subdev_get_try_* functions in the __V4L2_SUBDEV_MK_GET_TRY macro arguments: if you now do 'git grep v4l2_subdev_get_try_format' you will actually find the header where it is defined. One remark regarding the drivers/staging/media/davinci_vpfe patches: the *_init_formats() functions assumed that fh could be NULL. However, that's not true for this driver, it's always set. This is almost certainly a copy and paste from the omap3isp driver. I've updated the code to reflect the fact that fh is never NULL.

[media] platform: Make use of media_bus_format enum

2014-11-14T19:54:08+00:00

In order to have subsytem agnostic media bus format definitions we've moved media bus definition to include/uapi/linux/media-bus-format.h and prefixed values with MEDIA_BUS_FMT instead of V4L2_MBUS_FMT. Reference new definitions in all platform drivers.

[media] omap3isp: use true/false for boolean vars

[media] omap3isp: ccdc: Restart the CCDC immediately after an underrun in BT.656

2014-08-21T20:25:17+00:00

As the CCDC doesn't generate interrupts when stopped in BT.656 mode, restart it immediately when the next buffer after an underrun is queued instead of relying on the interrupt handler to restart the CCDC.

[media] omap3isp: ccdc: Don't timeout on stream off when the CCDC is stopped

2014-08-21T20:25:16+00:00

When the CCDC is already stopped due to a buffer underrun, the stop state machine won't advance in BT.656 mode as no interrupt are generated by the stopped CCDC in that mode. Handle this case explicitly in the ccdc_disable() function. Signed-off-by: Laurent Pinchart Tested-by: Enrico Butera Signed-off-by: Mauro Carvalho Chehab

[media] omap3isp: ccdc: Fix freeze when a short frame is received

2014-08-21T20:25:16+00:00

In BT.656 mode the synchronization signals are generated by the CCDC from the embedded sync codes. The VD0 and VD1 interrupts are thus only triggered when the CCDC is enabled, unlike external sync mode where the line counter runs even when the CCDC is stopped. We can't disable the CCDC at VD1 time, as no VD0 interrupt would be generated for a short frame, which would result in the CCDC being stopped and no VD interrupt generated anymore. The CCDC is stopped from the VD0 interrupt handler instead for BT.656. Signed-off-by: Laurent Pinchart Tested-by: Enrico Butera Signed-off-by: Mauro Carvalho Chehab
