We have an LCD display which runs at HD resolution of 1080x1920 interfaced via MIPI. Currently it's connected to an iMX6 dual core processor via a parallel-to-MIPI bridge (because the iMX6 MIPI interface does not support the LCD's display resolution). Our testing has revealed that we only need a single processor and have disabled one of the cores to save on power consumption. To save on costs, I'm looking at the solo or dual-lite chips to see if they could be used for our purposes (they are pin-compatible, according to the feature set).
According to the product summary pages for both solo and dual lite;
both chips only support display resolutions upto 1366x768 (thus, not suitable for my purposes).
But, according to the "iMX6 Solo/Dual lite Applications Processor Reference Manual" , section 18.104.22.168.2.2 Display Interface (pages 2793 - 2795) mentions,
For synchronous access with one cycle/pixel, this enables, e.g (including 35% blanking

• Software contrast control using 8-bit programmable pulse-width modulation (PWM)
Two dedicated PWM outputs are provided
So, I'd like some clarity on this matter - do the solo/dual-lite processors support 1080 HD resolution? If not, what is the datasheet referring to?

How to configure 1920x1080@60hz programmatically ?
i have converted the disp0 signal to hdmi using tfp410 dvi convertor, now how to configure the setting for hdmi display.
in DTS or driver file.
