Subject: Re: [PATCH v2 0/6] Support second Image Signal Processor on rk3399

Hey Heiko,

I have tested your series and it successfully fixes the problem with the
2nd camera when HDMI is connected at boot. Besides that the patch looks
good and my tests have confirmed that both cameras have the same output
quality when I exchange the connected ISP instances.

Tested-by: Sebastian Fricke <sebastian.fricke@...teo.net>

Greetings,
Sebastian
