[media] mx3-camera: locking cleanup in mx3_videobuf_queue()

2013-09-24T16:33:55+00:00

Smatch complains about the locking here because we mix spin_lock_irq()
with spin_lock_irqsave() in an unusual way.  According to Smatch, it's
not always clear if the IRQs are enabled or disabled when we return.  It
turns out this function is always called with IRQs enabled and we can
just use spin_lock_irq().
It's called from __enqueue_in_driver().

[media] V4L2: mx3_camera: add support for asynchronous subdevice registration

2013-08-18T12:06:37+00:00

The soc-camera core does all the work on supporting asynchronous
subdevice probing, host drivers only have to pass a subdevice list to
soc-camera. Typically this list is provided by the platform.

[media] V4L2: mx3_camera: print V4L2_MBUS_FMT_* codes in hexadecimal format

2013-08-18T12:05:43+00:00

V4L2_MBUS_FMT_* codes are defined in v4l2-mediabus.h as hexadecimal
constants. Print them in the same form for easier recognition.

[media] V4L2: mx3_camera: convert to managed resource allocation

2013-08-18T12:05:17+00:00

Use devm_* resource allocators to simplify the driver's probe and clean up
paths.

[media] V4L2: soc-camera: fix requesting regulators in synchronous case

2013-08-18T12:03:12+00:00

With synchronous subdevice probing regulators should be requested by the
soc-camera core in soc_camera_pdrv_probe(). Subdevice drivers, supporting
asynchronous probing, call soc_camera_power_init() to request regulators.
Erroneously, the same regulator array is used in the latter case as in
the former, which leads to a failure. This patch fixes it by preventing
the second regulator request from being executed.

[media] soc_camera: fix compiler warning

media_build/v4l/soc_camera.c: In function 'soc_camera_host_register':
media_build/v4l/soc_camera.c:1513:10: warning: 'sasd' may be used uninitialized in this function [-Wmaybe-uninitialized]

By changing the type of 'i' to unsigned and changing a condition we finally
convince the compiler that sasd is really initialized.

[media] V4L2: soc_camera: Renesas R-Car VIN driver

2013-08-18T12:01:10+00:00

Add Renesas R-Car VIN (Video In) V4L2 driver.
Based on the patch by Phil Edworthy .
[Sergei: removed deprecated IRQF_DISABLED flag, reordered/renamed 'enum chip_id'
values, reordered rcar_vin_id_table[] entries,  removed senseless parens from
to_buf_list() macro, used ALIGN() macro in rcar_vin_setup(), added {} to the
*if* statement  and used 'bool' values instead of 0/1 where necessary, removed
unused macros, done some reformatting and clarified some comments.]

[media] V4L: Rename subdev field of struct v4l2_async_notifier

2013-07-30T18:53:11+00:00

This is a purely cosmetic change. Since the 'subdev' member
points to an array of subdevs make it more explicit by
renaming to the plural form.

[media] V4L: Rename v4l2_async_bus_* to v4l2_async_match_*

2013-07-30T18:52:00+00:00

enum v4l2_async_bus_type also selects a method subdevs are matched
in the notification handlers, rename it to v4l2_async_match_type
so V4L2_ASYNC_MATCH_OF entry can be further added for matching by
device tree node pointer.
