2018-10-19media: rename soc_camera I2C driversMauro Carvalho Chehab
Those drivers are part of the legacy SoC camera framework. They're being converted to not use it, but sometimes we're keeping both legacy any new driver. This time, for example, we have two drivers on media with the same name: ov772x. That's bad. So, in order to prevent that to happen, let's prepend the SoC legacy drivers with soc_. No functional changes. Acked-by: Hans Verkuil <hans.verkuil@cisco.com> Signed-off-by: Mauro Carvalho Chehab <mchehab+samsung@kernel.org>
2018-10-15media: cec: forgot to cancel delayed workHans Verkuil
If the wait for completion was interrupted, then make sure to cancel any delayed work. This can only happen if a transmit is waiting for a reply, and you press Ctrl-C or reboot/poweroff or something like that which interrupts the thread waiting for the reply and then proceeds to delete the CEC message. Since the delayed work wasn't canceled, once it would trigger it referred to stale data and resulted in a kernel oops.

2018-10-09media: cx231xx: fix potential sign-extension overflow on large shiftColin Ian King
Shifting the u8 value[3] by an int can lead to sign-extension overflow. For example, if value[3] is 0xff and the shift is 24 then it is promoted to int and then the top bit is sign-extended so that all upper 32 bits are set. Fix this by casting value[3] to a u32 before the shift.

2018-10-09media: isif: fix a NULL pointer dereference bugWenwen Wang
In isif_probe(), there is a while loop to get the ISIF base address and linearization table0 and table1 address. In the loop body, the function platform_get_resource() is called to get the resource. If platform_get_resource() returns NULL, the loop is terminated and the execution goes to 'fail_nobase_res'. Suppose the loop is terminated at the first iteration because platform_get_resource() returns NULL and the execution goes to 'fail_nobase_res'. Given that there is another while loop at 'fail_nobase_res' and i equals to 0, one iteration of the second while loop will be executed. However, the second while loop does not check the return value of platform_get_resource(). This can cause a NULL pointer dereference bug if the return value is a NULL pointer. This patch avoids the above issue by adding a check in the second while loop after the call to platform_get_resource().

2018-10-05media: cec: fix the Signal Free Time calculationHans Verkuil
The calculation of the Signal Free Time in the framework was not correct. If a message was received, then the next transmit should be considered a New Initiator and use a shorter SFT value. This was not done with the result that if both sides where continually sending messages, they both could use the same SFT value and one side could deny the other side access to the bus. Note that this fix does not take the corner case into account where a receive is in progress when you call adap_transmit.

2018-10-05media: cec: add new tx/rx status bits to detect aborts/timeoutsHans Verkuil
If the HDMI cable is disconnected or the CEC adapter is manually unconfigured, then all pending transmits and wait-for-replies are aborted. Signal this with new status bits (CEC_RX/TX_STATUS_ABORTED). If due to (usually) a driver bug a transmit never ends (i.e. the transmit_done was never called by the driver), then when this times out the message is marked with CEC_TX_STATUS_TIMEOUT. This should not happen and is an indication of a driver bug. Without a separate status bit for this it was impossible to detect this from userspace. The 'transmit timed out' kernel message is now a warning, so this should be more prominent in the kernel log as well.

2018-10-04media: v4l: fwnode: Use V4L2 fwnode endpoint media bus type if setSakari Ailus
Use the given media bus type set by the caller. If none is given (i.e. the mbus type is V4L2_MBUS_UNKNOWN, or 0), fall back to the old behaviour. This is to obtain the information from the DT or try to guess the bus type. -ENXIO is returned if the caller sets the bus type but that does not match with what's in DT. Also return -ENXIO if bus type detection failed to separate this from the rest of the errors.

2018-10-04media: v4l: fwnode: Print bus typeSakari Ailus
Print bus type either as set by the driver or as parsed from the bus-type property, as well as the guessed V4L2 media bus type.

2018-10-04media: v4l: fwnode: Use default parallel flagsSakari Ailus
The caller may provide default flags for the endpoint. Change the configuration based on what is available through the fwnode property API.

2018-10-04media: v4l: fwnode: Use media bus type for bus parser selectionSakari Ailus
Use the media bus types instead of the fwnode bus types internally. This is the interface to the drivers as well, making the use of the fwnode bus types more localised to the V4L2 fwnode framework.
