2025-04-24platform/x86: int3472: Add handshake pin supportHans de Goede
New Intel Meteor Lake based laptops with IPU6 cameras have a new type 0x12 pin defined in the INT3472 sensor companion device which describes the sensor's GPIOs. This pin is primarily used on designs with a Lattice FPGA chip which is capable of running the sensor independently of the main CPU for features like presence detection. This pin needs to be driven high to make the FPGA run the power-on sequence of the sensor. After driving the pin high, the FPGA "firmware" needs 25ms to complete the power-on sequence. Add support for this modelling the handshake pin as a GPIO driven "dvdd" regulator with a 25 ms enable time. This model was chosen because: 1. Sensor chips don't have a handshake pin, so we need to abstract this in some way which does not require modification to the sensor drivers, sensor drivers using the bulk-regulator API to get avdd + vddio + dvdd is normal. So this will work to get the right value set to the handshake pin without requiring sensor driver modifications. 2. Sensors typically wait only a small time for the sensor to power-on after de-asserting reset. Not the 25ms the Lattice chip requires. Using the regulator framework's enable_time allows hiding the need for this delay from the sensor drivers.

2025-04-24platform/x86: int3472: Make regulator supply name configurableHans de Goede
This is a preparation patch for registering multiple regulators, which requires a different supply-name for each regulator. Make supply-name a parameter to skl_int3472_register_regulator() and use con-id to set it so that the existing int3472_gpio_map remapping can be used with it. Since supply-name is a parameter now, drop the fixed skl_int3472_regulator_map_supplies[] array and instead add lower- and upper-case mappings of the passed-in supply-name to the regulator.

-Wflex-array-member-not-at-end was introduced in GCC-14, and we are getting ready to enable it, globally. Move the conflicting declaration to the end of the structure. Notice that `struct acpi_resource_irq` is a flexible structure --a structure that contains a flexible-array member. Fix the following warning: drivers/platform/x86/sony-laptop.c:3330:41: warning: structure containing a flexible array member is not at the end of another structure [-Wflex-array-member-not-at-end] Signed-off-by: Gustavo A.

Create "pct_idle" counter group, the sofware notion of residency so it can now be singled out, independent of other counter groups. Create "cpuidle" group, the cpuidle invocation counts. Disable "cpuidle", by default. Create "swidle" = "cpuidle" + "pct_idle". Undocument "sysfs", the old name for "swidle", but keep it working for backwards compatibilty. Create "hwidle", all the HW idle counters Modify "idle", enabled by default "idle" = "hwidle" + "pct_idle" (and now excludes "cpuidle") Signed-off-by: Len Brown <len.brown@intel.com>

2025-04-06Disable SLUB_TINY for build testingLinus Torvalds
... and don't error out so hard on missing module descriptions. Before commit 6c6c1fc09de3 ("modpost: require a MODULE_DESCRIPTION()") we used to warn about missing module descriptions, but only when building with extra warnigns (ie 'W=1'). After that commit the warning became an unconditional hard error. And it turns out not all modules have been converted despite the claims to the contrary. As reported by Damian Tometzki, the slub KUnit test didn't have a module description, and apparently nobody ever really noticed. The reason nobody noticed seems to be that the slub KUnit tests get disabled by SLUB_TINY, which also ends up disabling a lot of other code, both in tests and in slub itself. And so anybody doing full build tests didn't actually see this failre. So let's disable SLUB_TINY for build-only tests, since it clearly ends up limiting build coverage. Also turn the missing module descriptions error back into a warning, but let's keep it around for non-'W=1' builds.
