[media] v4l2: pass std by value to the write-only s_std ioctl

2013-03-24T09:47:00+00:00

This ioctl is defined as IOW, so pass the argument by value instead of by
reference. I could have chosen to add const instead, but this is 1) easier
to handle in drivers and 2) consistent with the s_std subdev operation.

[media] davinci/dm644x_ccdc: fix compiler warning

2013-03-19T19:16:04+00:00

drivers/media/platform/davinci/dm644x_ccdc.c: In function ‘validate_ccdc_param’:
drivers/media/platform/davinci/dm644x_ccdc.c:233:32: warning: comparison between ‘enum ccdc_gama_width’ and ‘enum ccdc_data_size’ [-Wenum-compare]
It took a bit of work, see this thread of an earlier attempt to fix this:
https://patchwork.kernel.org/patch/1923091/
I've chosen not to follow the suggestions in that thread since gamma_width is
really a different property from data_size. What you really want is to know if
gamma_width fits inside data_size and for that you need to translate each
enum into a maximum bit number so you can safely compare the two.
So I put in two static inline translation functions instead, keeping the rest
of the code the same (except for fixing the 'gama' typo).

[media] davinci: remove VPBE_ENC_DV_PRESET and rename VPBE_ENC_CUSTOM_TIMINGS

2013-03-19T19:09:53+00:00

Remove VPBE_ENC_DV_PRESET (the DV_PRESET API is no longer supported) and
VPBE_ENC_CUSTOM_TIMINGS is renamed to VPBE_ENC_DV_TIMINGS since the old
"CUSTOM_TIMINGS" name is deprecated in favor of "DV_TIMINGS".

[media] davinci: vpbe: pass different platform names to handle different ip's

2012-12-21T16:18:50+00:00

The vpbe driver can handle different platforms DM644X, DM36X and
DM355. To differentiate between this platforms venc_type/vpbe_type
was passed as part of platform data which was incorrect. The correct
way to differentiate to handle this case is by passing different
platform names.
This patch creates platform_device_id[] array supporting different
platforms and assigns id_table to the platform driver, and finally
in the probe gets the actual device by using platform_get_device_id()
and gets the appropriate driver data for that platform.
Taking this approach will also make the DT transition easier.

[media] media: davinci: vpbe: fix build warning

2012-11-21T15:53:28+00:00

Warnings were generated because of the following commit changed data type for
address pointer
195bbca ARM: 7500/1: io: avoid writeback addressing modes for __raw_ accessors
add  __iomem annotation to fix following warnings
drivers/media/platform/davinci/vpbe_osd.c: In function ‘osd_read’:
drivers/media/platform/davinci/vpbe_osd.c:49:2: warning: passing
 argument 1 of ‘__raw_readl’ makes pointer from integer without a cast [enabled by default]
arch/arm/include/asm/io.h:104:19: note: expected ‘const volatile
 void *’ but argument is of type ‘long unsigned int’
This patch stores the ioremap_nocache() returned address in a
void __iomem * instead of a unsigned long and passes the same to
readl/writel functions which fixes the above warnings.

[media] media: davinci: vpif: display: separate out subdev from output

2012-10-06T01:12:27+00:00

vpif_display relied on a 1-1 mapping of output and subdev. This is not
necessarily the case. Separate the two. So there is a list of subdevs
and a list of outputs. Each output refers to a subdev and has routing
information. An output does not have to have a subdev.
The initial output for each channel is set to the fist output.
Currently missing is support for associating multiple subdevs with
an output.

struct vpif_interface is channel specific, not subdev specific.
