Enable the regulators when powering the sensor up, and disable them when powering it down. The regulators are mandatory. Boards that don't allow controlling the sensor power lines must provide fixed voltage regulators. Signed-off-by:

There is no need to check same bit before setting it, since we always end up with a bit set. Remove some of the tests and make set unconditional, in every place where all that needs to be done is just setting a bit. Signed-off-by:

Make the sensor subdevs host_data hold a pointer to struct fimc_source_info, which is defined in the driver's public header, rather than a pointer to struct fimc_sensor_info which is specific to exynos4-is media device driver. The purpose of this change is to allow easier reuse of the fimc-lite module in the exynos5-is driver, which should similarly store a pointer to struct fimc_source_info instance in the sensor's subdev host_data.

Get the sensor subdev by walking media graph in both cases: when the device is used as a subdev only and through video node. This allows to not dereference the pipeline->subdevs[] array and makes the module more generic and easier to re-use in other media driver. Signed-off-by:

Symbol rate ratio were using a rough calculus, as the code was limited to 32 bits arithmetic. Change it to 64 bits, in order to better estimate the bandwidth low-pass filter on the demod. This should reduce the noise and improve reception. Reported-by:

Using 'i' for the guard interval temporary var is a bad idea, as 'i' is generally used by "anonymous" indexes. Let's rename modulation, fec and guard interval temp vars with a meaningful name, as that makes easier to understand the code and avoids cut-and-paste types of error. Signed-off-by:

We're using the anonymous 'i' to indicate the layer number on several places on the driver. That's not good, as some cut-and-paste type of change might be doing the wrong thing. So, call it as "layer" everywhere. Signed-off-by:

config looks like a hack that was added to tuner-core to allow some configuration of TDA8290 tuner (it's not used by any other driver). But with the new configuration options of tda8290 driver (no_i2c_gate and std_map), it's no longer sufficient. Change config to be void * instead, which allows passing tuner-dependent config struct to drivers. Also update saa7134 driver to reflect this change (no other driver uses this). Signed-off-by:

Hauppauge Nova-S-Plus DVB-S model 92001 does not lock on horizontal polarisation. According with the info provided at the BZ, model 92002 does. The difference is that, on model 92001, the tone select is done via isl6421, while, on other devices, this is done via cx24123 code. This patch adds a way to override the demod's set_tone at isl6421 driver. In order to avoid regressions, the override is enabled only for cx88 Nova S plus model 92001. For all other models and devices, the set_tone is provided by the demod driver. Patch originally proposed at bz@9476[1] by Michel Meyers and John Donoghue but applying the original patch would break support for all other devices based on isl6421.

rc_unregister_device already calls rc_free_device to free the passed device. But in one of ttusbir's probe fail paths, we call rc_unregister_device _and_ rc_free_device. This is wrong and results in a double free. Instead, set rc to NULL resulting in rc_free_device being a noop. Signed-off-by:

"enum dmx_ts_pes" and "typedef enum dmx_pes_type_t" are just the same enum declared twice, since Kernel (2.6.12). There's no reason to duplicate it there, and sparse complains about that: drivers/media/dvb-core/dmxdev.c:600:55: warning: mixing different enum types So, remove the internal define, keeping just the external one. Internally, use only "enum dmx_ts_pes", as it is too late to drop dmx_pes_type_t from the userspace API. Signed-off-by:

This patch fixes erroneous setup of the YUV order caused by not clearing FIMC_REG_MSCTRL_ORDER422_MASK bit field before setting proper FIMC_REG_MSCTRL_ORDER422 bits. This resulted in false colors for YUYV, YVYU, UYVY, VYUY color formats, depending in what sequence those were configured by user space. YUV order definitions are corrected so that following convention is used: | byte3 | byte2 | byte1 | byte0 -------+-------+-------+-------+------ YCBYCR | CR | Y | CB | Y YCRYCB | CB | Y | CR | Y CBYCRY | Y | CR | Y | CB CRYCBY | Y | CB | Y | CR Signed-off-by: -

The FIMC-LITE output DMA allows to configure different YUV order than the order at the camera input interface. Thus there is some limited colorspace conversion possible. This patch makes the color format variable be per FIMC-LITE input/output, rather than a global per device. This also fixes incorrect behavior where color format at the FIMC-LITE.N subdev's source pad is modified by VIDIOC_S_FMT ioctl on the related video node. YUV order definitions are corrected so that we use notation: | byte3 | byte2 | byte1 | byte0 -------+-------+-------+-------+------ YCBYCR | CR | Y | CB | Y YCRYCB | CB | Y | CR | Y CBYCRY | Y | CR | Y | CB CRYCBY | Y | CB | Y | CR Signed-off-by: -

There is no need to use separate variant data structure for each FIMC-LITE IP instance. According to my knowledge there are no differences across them on Exynos4 as well as Exynos5 SoCs. Drop flite_variant data structure and use struct flite_drvdata instead. Signed-off-by:
