I got a ksz8794CNX that is poo poo and I hate this stupid loving switch. It's connected to an IMX6, and when I boot using the imx_usb_loader, 99% of the time the chip comes out of reset just fine. But if I boot off of EMMC the chip freaks out and get's pissy and refuses to auto-negotiate. Yank the reset GPIO low? Nah, doesn't work. Yank the 1v2 line low? Nah, doesn't work. The TRM has no power sequencing requirements either. gently caress Micrel and their stupid loving chips. Bloody posted:microchip is pretty awful, so its probable I was looking at this: http://www.microchip.com/wwwproducts/en/ATAES132A for future products. It's only 56c in 53c of 100+.

Sapozhnik posted:why does anybody use atmel for anything I was thinking about using a sha256 authentication chip from them. Seems cheap and would be nice for storing a private key yes? Is there another company/chip I should look at? Edit: Something like this: http://www.microchip.com/wwwproducts/en/ATSHA204A#buy 50c~ per unit seems ok.

Device tree is so easy to learn and good that if you don't understand it in a hour of looking at other device trees you are bad and shouldn't be modifying kernel code.
