Allows dingdong to receive initial USB PD communication (source
capabilities payload) and with some manual manipulation (see 'TEST=')
drive DPout.
CL is based heavily off hoho dongle where all files were copied from
board/hoho:
7b1e58c ectool: Add host command support to set fan RPM for each
fan separately
Files gpio.inc, board.h & board.c were modified but others should
be identical.
BRANCH=none
BUG=chrome-os-partner:31193
TEST=manual,
When attaching dingdong to samus_pd and configured via
'pd dualrole source'
I see following on samus_pd console:
C1 st9
Switch to 5000 V 900 mA (for 900/900 mA)
C1 st10
C1 st11
C1 st12
showing power constract and transition to SRC_RDY:
> pd 1 state
Port C1, Enabled - Role: SRC Polarity: CC1 State: SRC_READY
> typec 1 dp
Also if I connect in CC1 configuration and get access to dingdong
console I can
> gpioset PD_SBU_ENABLE 1
And see dingdong drive external monitor
