The rationale of having one directory per manufacturer is that, if drivers
for newer platforms with different names from the same manufacturers are 
added, those will still fit under allwinner/ and amlogic/.

The Kconfig names for sunxi and meson didn't change, nor the driver's name. 
Also, the directories under allwinner preserve sun<x>i name on them:

	drivers/media/platform/allwinner/
	├── sun4i-csi
	├── sun6i-csi
	├── sun8i-di
	└── sun8i-rotate

and so the directory under amlogic/:

	drivers/media/platform/amlogic/
	└── meson-ge2d

Now, if Allinner decides to release a new platforms named after another star,
let's say, "Vega" and "Rigel", it would be just a matter of adding 
"vega/" and "rigel/" directories under allwinner. No need to touch
media/platform/Kconfig and media/platform/Makefile. Everything will happen
on much more smaller vendor-specific Kconfig/Makefile.

See for instance, TI. We had initially a single driver, and everywhere it
was called "omap", which was had gained different versions (omap2, omap3, 
...). Then, TI decided to use other names for newer IP (davinci, am437x), 
and now the current development is at cal and vpe.

If we had placed a ti/ directory by the time omap were added (and the
same for the other vendors), we would have avoided the need of this
reorg.

Thanks,
