[PATCH 0/6] media: rcar-vin: Brush endpoint properties

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



Hello,
   this series touches the bindings and the driver handling endpoint
properties for digital subdevices of the R-Car VIN driver.

The first patch simply documents what are the endpoint properties supported
at the moment, then the second one extends them with 'data-active'.

As the VIN hardware allows to use HSYNC as data enable signal when the CLCKENB
pin is left unconnected, the 'data-active' property presence determinates
if HSYNC has to be used or not as data enable signal. As a consequence, when
running with embedded synchronism, and there is not HSYNC signal, it becomes
mandatory to specify 'data-active' polarity in DTS.

To address this, all Gen-2 boards featuring a composite video input and
running with embedded synchronization, now need that property to be specified
in DTS. Before adding it, remove un-used properties as 'pclk-sample' and
'bus-width' from the Gen-2 bindings, as they are not parsed by the VIN driver
and only confuse users.

Niklas, as you already know I don't have any Gen2 board. Could you give this
a spin on Koelsch if you like the series?

Thanks
   j
