* x86/platform/atom: Check state of Punit managed devices on s2idleJohannes Stezenbach2024-03-121-1/+53
| | | | | | | | | | | | | | | | | | | | | | | | For the Bay Trail or Cherry Trail SoC to enter the S0i3 power-level at s2idle suspend requires most of the hw-blocks / devices in the SoC to be in D3 when entering s2idle suspend. If some devices are not in D3 then the SoC will stay in a higher power state, consuming much more power from the battery then in S0i3. Use the new acpi_s2idle_dev_ops and acpi_register_lps0_dev() functionality to register a new s2idle check function which checks that all hardware blocks in the North complex (controlled by Punit) are in a state that allows the SoC to enter S0i3 and prints an error message for any device in D0.

| * x86: platform: no need to check return value of debugfs_create functionsGreg Kroah-Hartman2019-06-031-19/+4
| | | | | | | | | | | | | | | | | | | | | | | | | | When calling debugfs functions, there is no need to ever check the return value. The function can work or not, but the code logic should never do something different based on this.

* x86/platform/atom/punit: Add Punit device state debug driverSrinivas Pandruvada2015-05-071-0/+183
The patch adds a debug driver, which dumps the power states of all the North complex (NC) devices. This debug interface is useful to figure out the devices, which blocks the S0ix transitions on the platform. This is extremely useful during enabling PM on customer platforms and derivatives.
