Re: Re: [PATCH v2 2/2] drm: bridge: adv7511: Add support for ADV7535

["Togorean, Bogdan" <Bogdan.Togorean@analog.com>]

Hi Frieder,

I'm glad to find there are other persons interested in this driver and
especially support for ADV7535. Unfortunately I had to put on hold the
development due to other activities but I'll send V3 tomorrow.

I also started work on HDCP support for this driver and hope to send
soon a patch for that.

Best regards,
Bogdan
