2025-04-01platform/x86: ISST: Correct command storage data lengthSrinivas Pandruvada
After resume/online turbo limit ratio (TRL) is restored partially if the admin explicitly changed TRL from user space. A hash table is used to store SST mail box and MSR settings when modified to restore those settings after resume or online. This uses a struct isst_cmd field "data" to store these settings. This is a 64 bit field. But isst_store_new_cmd() is only assigning as u32. This results in truncation of 32 bits. Change the argument to u64 from u32.

The DT bindings for ov7251 specify "enable" GPIO (xshutdown in documentation) but the int3472 indiscriminately provides this as a "reset" GPIO to sensor drivers. Take this into account by assigning it as "enable" with active high polarity for INT347E devices, i.e. ov7251. "reset" with active low polarity remains the default GPIO name for other devices.

2024-12-10platform/x86: int3472: Make "pin number mismatch" message a debug messageHans de Goede
It seems that Windows is only using the ACPI GPIO resources and never looks at the part of the _DSM return value which encodes the pin number. For example on a Terra Pad 1262 v2 the following messages are printend: int3472-discrete INT3472:01: reset \_SB.GPI0 pin number mismatch _DSM 103 resource 359 int3472-discrete INT3472:01: powerdown \_SB.GPI0 pin number mismatch _DSM 207 resource 335 int3472-discrete INT3472:02: reset \_SB.GPI0 pin number mismatch _DSM 101 resource 357 Notice for the 2 reset pins that the _DSM value is off by 256, this is caused by there only being 8 bits reserved in the _DSM return value for the pin-number. As for the powerdown pin, testing has shown that the pin-number 335 from the ACPI GPIO resource is correct and the _DSM value is bogus. Lower the warning about these mismatches to a debug message and only look at the lower 8 bits of the GPIO resource pin numbers.

2024-12-10platform/x86: int3472: Check for adev == NULLHans de Goede
Not all devices have an ACPI companion fwnode, so adev might be NULL. This can e.g. (theoretically) happen when a user manually binds one of the int3472 drivers to another i2c/platform device through sysfs. Add a check for adev not being set and return -ENODEV in that case to avoid a possible NULL pointer deref in skl_int3472_get_acpi_buffer().

2024-12-10platform/x86/intel: bytcrc_pwrsrc: Optionally register a power_supply devHans de Goede
On some Android tablets with Crystal Cove PMIC the DSDT lacks an ACPI AC device to indicate whether a charger is plugged in or not. Add support for registering a "crystal_cove_pwrsrc" power_supply class device to indicate charger online status. This is made conditional on a "linux,register-pwrsrc-power_supply" boolean device-property to avoid registering a duplicate power_supply class device on devices where this is already handled by an ACPI AC device. Note the "linux,register-pwrsrc-power_supply" property is only used on x86/ACPI (non devicetree) devs and the devicetree-bindings maintainers have requested properties like these to not be added to the devicetree bindings, so the new property is deliberately not added to any bindings.
