This patch removes the requirement for an IRQ, because for the core functionality IRQ isn't needed. So this makes the DA9061/62 chip usable for designs which haven't connected the IRQ pin. Signed-off-by:

With commit dd77f5fa97d3 ("mfd: Remove toshiba tmio drivers") the last mfd driver that implements these callbacks is gone and since commit 652719b1 ("w1: remove ds1wm driver") the last user is gone. The corresponding functions mfd_cell_enable() and mfd_cell_disable() are also unused (since commit 0ca222c8 ("leds: Remove asic3 driver")).

Implement a regulator driver with IRQ support for fault management. Written against documentation [1] and [2] and tested on real hardware. Every channel has it's own regulator supply nammed 'vss1-supply' and 'vss2-supply'. The regulator supply is used to determine the output voltage, as the smart switch provides no output regulation. The driver requires the 'shunt-resistor-micro-ohms' to be present in the devicetree to properly calculate current related values. You must specify compatible devictree layout: regulator@3a { reg = <0x3a>; vss1-supply = <&p3v3>; compatible = "maxim,max5978"; ... regulators { sw0_ref: SW0 { regulator-compatible = "SW0"; shunt-resistor-micro-ohms = <12000>; ... } } } 1: https://datasheets.maximintegrated.com/en/ds/MAX5970.pdf 2: https://datasheets.maximintegrated.com/en/ds/MAX5978.pdf ...

It seems that this driver was developed based on preliminary documentation. Report the correct names for all TQMxE39x variants, as they are used by the released hardware revisions: - Fix names for TQMxE39C1/C2 board IDs - Distinguish TQMxE39M and TQMxE39S, which use the same board ID The TQMxE39M/S are distinguished using the SAUC (Sanctioned Alternate Uses Configuration) register of the GPIO controller. This also prepares for the correct handling of the differences between the GPIO controllers of our COMe and SMARC modules.

Registers 0x160..0x17f are unassigned. Use 0x180 as base register and update offets accordingly. Also change the size of the range to include 0x19f. While 0x19f is currently reserved for future extensions, so are several of the previous registers up to 0x19e, and it is weird to leave out just the last one.

The I2C_DETECT register is at IO port 0x1a7, which is outside the range passed to devm_ioport_map() for io_base, and was only working because there aren't actually any bounds checks for IO port accesses. Extending the range does not seem like a good solution here, as it would then conflict with the IO resource assigned to the I2C controller. As this is just a one-off access during probe, use a simple inb() instead. While we're at it, drop the unused define TQMX86_REG_I2C_INT_EN.

Since commit 8b41fc44 ("kbuild: create modules.builtin without Makefile.modbuiltin or tristate.conf"), MODULE_LICENSE declarations are used to identify modules. As a consequence, uses of the macro in non-modules will cause modprobe to misidentify their containing object file as a module when it is not (false positives), and modprobe might succeed rather than failing with a suitable error message. So remove it in the files in this commit, none of which can be built as modules. Suggested-by:

Remove pm8008_init(), which according to the comments exists only as a workaround for regmap-irq's odd treatment of type registers. This workaround shouldn't be needed anymore because this driver uses config registers, which are always programmed by regmap-irq no matter what the initial register state is. Signed-off-by:

The usual behavior of mask registers is writing a '1' bit to disable (mask) an interrupt; similarly, writing a '1' bit to an unmask register enables (unmasks) an interrupt. Due to a longstanding issue in regmap-irq, mask and unmask registers were inverted when both kinds of registers were present on the same chip, ie. regmap-irq actually wrote '1's to the mask register to enable an IRQ and '1's to the unmask register to disable an IRQ. This was fixed by commit e8ffb12e ("regmap-irq: Fix inverted handling of unmask registers") but the fix is opt-in via mask_unmask_non_inverted = true because it requires manual changes for each affected driver. The new behavior will become the default once all drivers have been updated. The PM8008 appears to rely on the inverted behavior. It has separate set & clear registers for a register called INT_EN, which presumably enables interrupts by writing '1's. Opt in to the new non-inverted behavior & swap mask_base/unmask_base.

The Android Lenovo Yoga Book X90F / X90L uses the same charger / fuelgauge setup as the already supported Windows Lenovo Yoga Book X91F/L, add a DMI match for this to intel_cht_wc_models with driver_data set to INTEL_CHT_WC_LENOVO_YOGABOOK1. When the quirk for the X91F/L was initially added it was written to also apply to the X90F/L but this does not work because the Android version of the Yoga Book uses completely different DMI strings. Also adjust the X91F/L quirk to reflect that it only applies to the X91F/L models. Signed-off-by:

There is a problem with the behavior of hwlat in a container, resulting in incorrect output. A warning message is generated: "cpumask changed while in round-robin mode, switching to mode none", and the tracing_cpumask is ignored. This issue arises because the kernel thread, hwlatd, is not a part of the container, and the function sched_setaffinity is unable to locate it using its PID. Additionally, the task_struct of hwlatd is already known. Ultimately, the function set_cpus_allowed_ptr achieves the same outcome as sched_setaffinity, but employs task_struct instead of PID. Test case: # cd /sys/kernel/tracing # echo 0 > tracing_on # echo round-robin > hwlat_detector/mode # echo hwlat > current_tracer # unshare --fork --pid bash -c 'echo 1 > tracing_on' # dmesg -c Actual behavior: [573502.809060] hwlat_detector: cpumask changed while in round-robin mode, switching to mode none Link: https://lore.kernel.org/linux-trace-kernel/20230316144535.1004952-1-costa.shul@redhat.com Cc: Masami Hiramatsu <mhiramat@kernel.org> Fixes: 0330f7aa ("tracing: Have hwlat trace migrate across tracing_cpumask CPUs") Signed-off-by:

The comment refers to mm/slob.c which is being removed. It comes from commit ed56829c ("ring_buffer: reset buffer page when freeing") and according to Steven the borrowed code was a page mapcount and mapping reset, which was later removed by commit e4c2ce82 ("ring_buffer: allocate buffer page pointer"). Thus the comment is not accurate anyway, remove it.
