* platform/x86: pmc_atom: Check state of PMC clocks on s2idleHans de Goede2024-03-121-0/+11
| | | | | | | | | | | Extend the s2idle check with checking that none of the PMC clocks is in the forced-on state. If one of the clocks is in forced on state then S0i3 cannot be reached.

* platform/x86: pmc_atom: Check state of PMC managed devices on s2idleJohannes Stezenbach2024-03-121-0/+68
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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 South complex (controlled by the PMC) are in a state that allows the SoC to enter S0i3 and prints an error message for any device in D0. Some blocks are not used on lower-featured versions of the SoC and these blocks will always report being in D0 on SoCs were they are not used. A false-positive mask is used to identify these blocks and for blocks in this mask the error is turned into a debug message to avoid false-positive error messages. Note the pmc_atom code is enabled by CONFIG_X86_INTEL_LPSS which already depends on ACPI.

Looking at: https://www.lex.com.tw/products/embedded-ipc-board/ we can see that Lex BayTrail makes many embedded boards with multiple ethernet boards and none of their products are battery powered so we don't need to worry (too much) about power consumption when suspended. Add a new DMI match which simply matches all Lex BayTrail boards and drop the 2 existing board specific quirks.

It's rather big, since includes two big refactors and completely new driver: - ASUS WMI driver got a big refactoring in order to support the TUF Gaming laptops. Besides that, the regression with backlight being permanently off on various EeePC laptops has been fixed. - Accelerometer on HP ProBook 450 G0 shows wrong measurements due to X axis being inverted. This has been fixed. - Intel PMC core driver has been extended to be ACPI enumerated if the DSDT provides device with _HID "INT33A1". This allows to convert the driver to be pure platform and support new hardware purely based on ACPI DSDT. - From now on the Intel Speed Select Technology is supported thru a corresponding driver. This driver provides an access to the features of the ISST, such as Performance Profile, Core Power, Base frequency and Turbo Frequency. - Mellanox platform drivers has been refactored and now extended to support more systems, including new coming ones. - The OLPC XO-1.75 platform is now supported. - CB4063 Beckhoff Automation board is using PMC clocks, provided via pmc_atom driver, for ethernet controllers in a way that they can't be managed by the clock driver. The quirk has been extended to cover this case. - Touchscreen on Chuwi Hi10 Plus tablet has been enabled. Meanwhile the information of Chuwi Hi10 Air has been fixed to cover more models based on the same platform. - Xiaomi notebooks have WMI interface enabled. Thus, the driver to support it has been provided. It required some extension of the generic WMI library, which allows to propagate opaque context to the ->probe() of the individual drivers. This release includes debugfs clean up from Greg KH for several drivers that drop return code check and make debugfs absence or failure non-fatal.
