IMX6Q Linux Driver Help for ADV7343 Encoder

tengri — Wed, 21 Sep 2016 15:16:47 GMT

Hello All,

I have an elementary question particularly related to the linux drivers in IMX6Q for ADV7343 encoder chip. Since it's a parallel pixel data to cvbs converter I think this should be able to interface as a display driver to parallel RGB interface (display) of IMX6. In most of the display driver examples (lcd, ldb) and dts files, the driver has been incorporated with an mxc frame buffer (mxcfbx) and an fbx. But the driver available in linux kernel source (link below) does not have mxcfb assignments (but v4l2 functions). So my question is does this driver enumerate as a video output device in imx6 ? Or should there be mxcfb routines to support this chip as a display device ?

Thank You

Hi Anuradha

seems one can reuse parallel i.MX6 IPU WVGA drivers in

drivers/video//fbdev/mxc/mxc_lcdif.c

described in attached Linux Manual Table 6-1. IPU Driver Files.

Regarding adv7343.c implementation details, one can post it on

https://www.linuxtv.org/wiki/index.php/V4L2_Userspace_Library

Best regards
igor
