Create necessary boiler plate files for USB type-C to HDMI dongle.
BRANCH=none
BUG=chrome-os-partner:31192
TEST=manual
1. Compiles & can program via fruitpie.
2. Can access uart (w/ rework for tx/rx).
3. Can drive HDMI capable monitor.
test details ...
Programming:
------------
# connect fruitpie + fruitpie std-adapter(red) with u-USB (CN3) & type-A
# (CN1) both to host that will run servod.
FPIE_PORT=9993
sudo servod -p 0x5009 --port $FPIE_PORT
dut-control --port $FPIE_PORT "ec_uart_cmd:gpioset USB_C_5V_EN 1"
dut-control --port $FPIE_PORT "ec_uart_cmd:usbmux usb"
util/flash_ec --board=hoho
Configuring samus for DPout on both ports:
------------------------------------------
sudo servod -b samus
for port 0 1; do
dut-control "usbpd_uart_cmd:pd ${PORT} dualrole off"
dut-control "usbpd_uart_cmd:gpioset USB_C${PORT}_CHARGE_EN_L 1"
dut-control "usbpd_uart_cmd:typec ${PORT} dp"
dut-control "usbpd_uart_cmd:gpioset USB_C${PORT}_5V_EN 1"
dut-control "usbpd_uart_cmd:typec ${PORT}"
done
