These changes actually came from Linux kernel. They are scattered in 
several files. I included only those are prevalent to u-boot.

8250.txt
- compatible : one of:
	- "ns8250"
	- "ns16450"
	- "ns16550a"
	- "ns16550"
	- "ns16750"
	- "ns16850"
	- For Tegra20, must contain "nvidia,tegra20-uart"
	- For other Tegra, must contain '"nvidia,<chip>-uart",
	  "nvidia,tegra20-uart"' where <chip> is tegra30, tegra114, tegra124,
	  tegra132, or tegra210.

omap_serial.txt
- compatible : should be "ti,omap2-uart" for OMAP2 controllers
- compatible : should be "ti,omap3-uart" for OMAP3 controllers
- compatible : should be "ti,omap4-uart" for OMAP4 controllers
- compatible : should be "ti,am4372-uart" for AM437x controllers
- compatible : should be "ti,am3352-uart" for AM335x controllers
- compatible : should be "ti,dra742-uart" for DRA7x controllers

snps-dw-apb-uart.txt
- compatible : "snps,dw-apb-uart"
- reg-shift : quantity to shift the register offsets by.  If this 
property is not present then the register offsets are not shifted.

I can change the description reg-shift property to above if this make it 
clearer.

I would agree that we can remove these copies of Linux kernel. Almost 
every dts binding I added to u-boot these months are copied from Linux 
kernel.

Best regards,
Thomas
