The nt35950 IC from Novatek is a Driver IC used to drive MIPI-DSI panels,
|
||||
with Static RAM for content retention in command mode and also supports
|
||||
video mode with VESA Frame Buffer Compression or Display Stream Compression
|
||||
on single, or dual dsi port(s).
|

This DDIC is also capable of upscaling an input image to the panel's native
|
||||
resolution, for example it can upscale a 1920x1080 input to 3840x2160 with
|
||||
either bilinear interpolation or pixel duplication.

Registration of 'advanced' EM
|

~~~~~~~~~~~~~~~~~~~~~~~~~~~~~

The 'advanced' EM gets it's name due to the fact that the driver is allowed

formula in the framework (like it's in 'simple' EM case). It can better reflect

the real power measurements performed for each performance state. Thus, this

Registration of 'simple' EM

~~~~~~~~~~~~~~~~~~~~~~~~~~~

The 'simple' EM is registered using the framework helper function

Power = C * V^2 * f
