stm32: assert/de-assert GPIO_PMIC_PWRON_L with keyboard power event
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
