Wolf Pass power control

[Vijay Khemka]

Just see if you are missing gpio line names patch from intel in your kernel device tree. Mainly look for PSPowerOK pin if it is configured properly in device tree.

Subject: Wolf Pass power control

I’m working on a Wolf Pass build for Phoenix and am having issues with power control.  I believe I’ve got all the GPIOs setup correctly and the power-control service is running.  It asserts POWER_OUT but it’s timing out waiting for PS_PWROK assertion.

As far as I can tell, those GPIOs are setup exactly like it’s setup on the IntelBMC version.  Is there anything that jumps out at you here that I might look at next?  I’m not sure why asserting POWER_OUT wouldn’t cause a power up sequence to occur.

## Current behavior of my wolf pass build at power on request
Jan 01 00:02:42 wolfpass power-control[224]: powerStateFailedTransitionToOn: power-on request event received
Jan 01 00:02:42 wolfpass power-control[224]: power supply power OK watchdog timer started
Jan 01 00:02:42 wolfpass power-control[224]: Moving to "Wait for Power Supply Power OK" state
Jan 01 00:02:42 wolfpass power-control[224]: POWER_OUT set to 0
Jan 01 00:02:42 wolfpass power-control[224]: Error in finding CurrentHostState property
Jan 01 00:02:42 wolfpass power-control[224]: POWER_OUT released
Jan 01 00:02:50 wolfpass power-control[224]: power supply power OK watchdog timer expired
Jan 01 00:02:50 wolfpass power-control[224]: powerStateWaitForPSPowerOK: power supply power OK watchdog timer expired event received
Jan 01 00:02:50 wolfpass power-control[224]: Moving to "Failed Transition to On" state
Jan 01 00:02:50 wolfpass power-control[224]: PowerControl: power supply power good failed to assert
