* Revert "[media] Add device tree support to adp1653 flash driver"Mauro Carvalho Chehab2015-04-091-81/+9
| | | | | | | | | | | | | As requested by Sakari: "The driver changes are still being reviewed. It's been proposed that the max-microamp property be renamed." So, as the DT bindings are not agreed upstream yet, let's revert it. Requested-by: Sakari Ailus <sakari.ailus@iki.fi> This reverts commit b6100f10bdc2019a65297d2597c388de2f7dd653.

* [media] v4l2-subdev: replace v4l2_subdev_fh by v4l2_subdev_pad_configHans Verkuil2015-03-2318-243/+249
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Analog video inputs are the tuner, plus composite, svideo, etc, e. g. the input pat should actually be like: ___________ TUNER --------> | | | | SVIDEO .......> | cx25840 | | | COMPOSITE1 ...> |_________| (in the above, dashes represent the enabled link, and periods represent the disabled ones) In other words, if we want to properly represent the pipeline, it should be possible to see via the media controller if the tuner is being used as an image source, or if the source is something else. I didn't map those other inputs here yet, due to a few things: - The extra inputs would require subdevs that won't be controlled - I was in doubt about the best way for doing that - That would likely require some extra setup for cx25840 caller drivers, in order to represent what of the possible internal inputs are actually used on each specific board Actually, at least for now, I was unable to see much benefit on adding such map now, so let's just document it, as this could be added later on, as needed.

* [media] adv7180: Do implicit register pagingLars-Peter Clausen2015-02-021-101/+105
| | | | | | | | | | | | | | | | | | | | | | | | The ad7180 has multiple register pages which can be switched between by writing to a register. Currently the driver manually switches between pages whenever a register outside of the default register map is accessed and switches back after it has been accessed. This is a bit tedious and also potential source for bugs. This patch adds two helper functions that take care of switching between pages and reading/writing the register. The register numbers for registers are updated to encode both the page (in the upper 8-bits) and the register (in the lower 8-bits) numbers. Having multiple pages means that a register access is not a single atomic i2c_smbus_write_byte_data() or i2c_smbus_read_byte_data() call and we need to make sure that concurrent register access does not race against each other.

* [media] adv7180: Cleanup register define namingLars-Peter Clausen2015-02-021-53/+52
| | | | | | | | | | | | Consistently prefix register defines with ADV7180_REG. Also remove the "ADI" from register names, the ADV7180 prefix should provide enough of a namespace separation.

* [media] adv7180: Pass correct flags to request_threaded_irq()Lars-Peter Clausen2015-02-021-1/+2
| | | | | | | | | | | | | Most IRQ controllers support different types of interrupts. The adv7180 generates falling edge interrupts, so make sure to pass IRQF_TRIGGER_FALLING to request_threaded_irq() so the IRQ controller is configured for the correct mode.

* [media] adv7180: Do not request the IRQ again during resumeLars-Peter Clausen2015-02-021-6/+7
| | | | | | | | | | | | | | Currently the IRQ is requested from within the init_device() function. This function is not only called during device probe, but also during resume causing the driver to try to request the IRQ again. Move requesting the IRQ from init_device() to the probe function to make sure that it is only requested once.

| | | | | | | | | | | of_read_number() is defined in of.h but does not return an error code, so that non-of implementation could simply return an error. Temporarily work around this until of_read_number() can be replaced by of_property_read_u64_array().
