Pull media updates from Mauro Carvalho Chehab:
 "Brazil's Independence Day pull request :-)

  This is one of the biggest media pull requests, with 625 patches
  affecting almost all parts of media (RC, DVB, V4L2, CEC, docs).

  This contains:

   - A lot of new drivers:
     * DVB frontends: mxl5xx, stv0910, stv6111;
     * camera flash: as3645a led driver;
     * HDMI receiver: adv748X;
     * camera sensor: Omnivision 6650 5M driver (ov6650);
     * HDMI CEC: ao-cec meson driver;
     * V4L2: Qualcom camss driver;
     * Remote controller: gpio-ir-tx, pwm-ir-tx and zx-irdec drivers.

   - The DDbridge DVB driver got a massive update, with makes it in sync
     with modern hardware from that vendor;

   - There's an important milestone on this series: the DVB
     documentation was written in 2003, but only started to be updated
     in 2007. It also used to contain several gaps from the time it was
     kept out of tree, mentioning error codes and device nodes that
     never existed upstream. On this series, it received a massive
     update: all non-deprecated digital TV APIs are now in sync with the
     current implementation;

   - Some DVB APIs that aren't used by any upstream driver got removed;

   - Other parts of the media documentation algo got updated, fixing
     some bugs on its PDF output and making it compatible with Sphinx
     version 1.6.

     As the number of hacks required to build PDF output reduced, I hope
     we'll have less troubles as newer versions of our documentation
     toolchain are released (famous last words);

   - As usual, lots of driver cleanups and improvements"

dma-coherent: remove the DMA_MEMORY_MAP and DMA_MEMORY_IO flags

2017-09-01T09:59:17+00:00

DMA_MEMORY_IO was never used in the tree, so remove it.  That means there is
no need for the DMA_MEMORY_MAP flag either now, so remove it as well and
change dma_declare_coherent_memory to return a normal errno value.

media: mx2_emmaprp: Check for platform_get_irq() error

2017-08-27T11:50:48+00:00

platform_get_irq() may fail, so we should better check its return
value and propagate it in the case of error.

media: omap3isp: fix uninitialized variable use

2017-08-27T00:14:42+00:00

A debug printk statement was copied incorrectly into the new
csi1 parser code and causes a warning there:

drivers/media/platform/omap3isp/isp.c: In function 'isp_probe':
include/linux/dynamic_debug.h:134:3: error: 'i' may be used uninitialized in this function [-Werror=maybe-uninitialized]

Since there is only one lane, the index is never set. This
changes the debug print to always print a zero instead,
keeping the original format of the message.

media: camss: Use optimal clock frequency rates

2017-08-26T19:31:06+00:00

Use standard V4L2 control to get pixel clock rate from a sensor
linked in the media controller pipeline. Then calculate clock
rates on CSIPHY, CSID and VFE to use the lowest possible.

If the currnet pixel clock rate of the sensor cannot be read then
use the highest possible. This case covers also the CSID test
generator usage.

If VFE is already powered on by another pipeline, check that the
current VFE clock rate is high enough for the new pipeline.
If not return busy error code as VFE clock rate cannot be changed
while VFE is running.
