MEI NFC
|
|
-------
|
|
|
|
Some Intel 8 and 9 Series chipsets support NFC devices connected behind
|
|
the Intel Management Engine controller.
|
|
MEI client bus exposes the NFC chips as NFC phy devices and enables
|
|
binding with Microread and NXP PN544 NFC device driver from the Linux NFC
|
|
subsystem.
