driver/tcpm/it8xxx2: PD driver for chip it8xxx1/8xxx2
Add PD driver for chip it8xxx1/8xxx2 series.
BRANCH=none
BUG=none
TEST=test below functions on PDEVB port0, 1, 2 with TCPMv1
(set cc toggle by console cmd):
1.pin configuration
console cmd "gpioget" check gpio settings.
memory dump check cc pin alternate settings.
2.Tx data error handle
Message discard, No GoodCRC, Tx not enable, Timeout
errors happen, corresponding INT will be triggered
then do properly handle.
3.basic pd connection
SNK:connect with adaptor, request max power (15V,3A),
state SNK_READY.
SRC:enable DRP role,
connect with dongle, provide power (5V,1.5A),
source Vconn 5v, get ack of cable discover id,
state SRC_READY.
4.pd module disable
SNK:connect with adapter.
console cmd "hibernate sec", driver disable pd module,
check still connection with adapter via dead battery rd.
And when resume from hibernate, pd init can re-enable
pd module, re-connect with adapter.
SRC:connect with dongle.
console cmd "hibernate sec", driver disable pd module,
check cc pin (not Vconn source pin) volt power down
to ~0v. And when resume from hibernate, pd init can
re-enable pd module, re-connect with dongle.
5.Tx hard reset
console cmd "pd port hard", check hard reset message by
lecroy analyzer.
6.Tx cable reset
check cable reset message by lecroy analyzer.
7.SOP' enable
SRC:connects to SNK via E-mark cable.
Source Vconn successfully, and receives cable's ack
of discover id request.
Not source Vconn to cable, and receives nothing
of discover id request (this isn't effect on
request SNK flow).
8.power role swap
console cmd "pd port swap power", check pd protocol
by lecroy.
