d65bf04200 mei: hdcp: use own Kconfig file
The mei/hdcp module have its own Makefile
so naturally it should have associated Kconfig
in the same directory.

64e9bbdd95 misc/mei/hdcp: Client driver for HDCP application
ME FW contributes a vital role in HDCP2.2 authentication.
HDCP2.2 driver needs to communicate to ME FW for each step of the
HDCP2.2 authentication.

ME FW prepare and HDCP2.2 authentication  parameters and encrypt them
as per spec. With such parameter Driver prepares HDCP2.2 auth messages
and communicate with HDCP2.2 sink.

Similarly HDCP2.2 sink's response is shared with ME FW for decrypt and
verification.

Once All the steps of HDCP2.2 authentications are complete on driver's
request ME FW will configure the port as authenticated and supply the
HDCP keys to the Gen HW for encryption.

Only after this stage HDCP2.2 driver can start the HDCP2.2 encryption
for a port.

ME FW is interfaced to kernel through MEI Bus Driver. To obtain the
HDCP2.2 services from the ME FW through MEI Bus driver MEI Client
Driver is developed.

fdd9b86559 mei: wd: drop the watchdog code from the core mei driver
Instead of integrating the iAMT watchdog in the mei core driver
we will create a watchdog device on the mei client bus and
create a driver for it.

This patch removes the watchdog code from the mei core driver.

on WATCHDOG_CORE as well

nothing, so let's get rid of it.

ffc2825c29 Staging: mei: move the mei code out of staging
It's been cleaned up, and there's nothing else left to do, so move it
out of staging into drivers/misc/ where all can use it now.
