This sets the PMIC_PWRON_L signal to correspond with the keyboard power button state. BUG=chrome-os-partner:9821 TEST=Tested on Lucas (see notes below) Signed-off-by: David Hendricks <dhendrix@chromium.org> 1. AC power plugged in, AP off, EC booted > gpioget PMIC_PWRON_L 1* PMIC_PWRON_L 2. AP running, press and release power button (should see screen zoom out and then back in, but I don't have a monitor...) 2a. AP running, power button not pressed > gpioget PMIC_PWRON_L 1 PMIC_PWRON_L 2b. Press power button > Waiting for long power press 280507864 > gpioget PMIC_PWRON_L 0* PMIC_PWRON_L 2c. release power button before 8s > Cancel power off > gpioget PMIC_PWRON_L 1* PMIC_PWRON_L 3. From AP off state, press and hold keyboard power button > gpioget PMIC_PWRON_L 0* PMIC_PWRON_L After 8s, we see: Timeout waiting for GPIO 0/KB_PWR_ON_L Power button was not released in time Shutdown complete. 4. AP on, press and hold keyboard power button > gpioget PMIC_PWRON_L 1 PMIC_PWRON_L > Waiting for long power press 654024769 > gpioget PMIC_PWRON_L 0* PMIC_PWRON_L > Power off after long press now=654025073, 0 ending loop 2 Shutdown complete. <-- Note: This message comes from power_off() which also de-asserts PMIC_PWRON_L > gpioget PMIC_PWRON_L 1* PMIC_PWRON_L Change-Id: I6955771707ecea2926570be0e8bd77ebddbca4d4
- EC Lib
This wraps Blizzard driverlib and implements the EC chip interface defined
by Google. See below diagram for architecture.

---- chip interface ---- The interface is defined in
src/platform/ec/chip_interface/*.
+--------------------+ But the real implementation is in EC Lib.
