Linus Torvalds 449fcf3ab0 Staging/IIO patches for 4.15-rc1
Here is the "big" staging and IIO driver update for 4.15-rc1.
 
 Lots and lots of little changes, almost all minor code cleanups as the
 Outreachy application process happened during this development cycle.
 Also happened was a lot of IIO driver activity, and the typec USB code
 moving out of staging to drivers/usb (same commits are in the USB tree
 on a persistent branch to not cause merge issues.)
 
 Overall, it's a wash, I think we added a few hundred more lines than
 removed, but really only a few thousand were modified at all.
 
 All of these have been in linux-next for a while.  There might be a
 merge issue with Al's vfs tree in the pi433 driver (take his changes,
 they are always better), and the media tree with some of the odd atomisp
 cleanups (take the media tree's version).

Introduction:
	SM750 of Silicon MOtion is pci express display controller device.
	The SM750 embedded graphics features include:
	- dual display
	- 2D acceleration
	- 16MB integrated video memory

About the kernel module parameter of driver:

	Use 1280,8bpp index color and 60 hz mode:
	insmod ./sm750fb.ko g_option="1280x1024-8@60"

	Disable MTRR,Disable 2d acceleration,Disable hardware cursor,
	and use a 800x600 mode :
	insmod ./sm750fb.ko g_option="noaccel:nomtrr:nohwc:800x600"

	dual frame buffer for driver with "dual" parameter
	insmod ./sm750fb.ko g_option="dual,800x600:1024x768"
	it will create fb0 and fb1 (or fb1,fb2 if fb0 already exist) under /dev
	and user can use con2fb to link fbX and ttyX

	Notes:
	1) if you build the driver with built-in method, the parameter
		you edited in the grub config file will be also the
		same format as above modular method,but additionally add
		"video=sm750fb:"
		ahead of parameters,so,it looks like:
		video=sm750fb:noaccel,1280x1024@60,otherparam,etc...
		it equal to modular method with below command:
		insmod ./sm750fb.ko g_option="noaccel:1280x1024@60:otherparm:etc..."

	2) if you put 800x600 into the parameter without bpp and
		refresh rate, kernel driver will defaulty use 16bpp and 60hz

Important:
	if you have vesafb enabled in your config then /dev/fb0 will be created by vesafb
	and this driver will use fb1, fb2. In that case, you need to configure your X-server
	to use fb1. Another simple althernative is to disable vesafb from your config.
