2023-08-18mfd: rz-mtu3: Link time dependenciesArnd Bergmann3-68/+2
The new set of drivers for RZ/G2L MTU3a tries to enable compile-testing the individual client drivers even when the MFD portion is disabled but gets it wrong, causing a link failure when the core is in a loadable module but the other drivers are built-in: x86_64-linux-ld: drivers/pwm/pwm-rz-mtu3.o: in function `rz_mtu3_pwm_apply': pwm-rz-mtu3.c:(.text+0x4bf): undefined reference to `rz_mtu3_8bit_ch_write' x86_64-linux-ld: pwm-rz-mtu3.c:(.text+0x509): undefined reference to `rz_mtu3_disable' arm-linux-gnueabi-ld: drivers/counter/rz-mtu3-cnt.o: in function `rz_mtu3_cascade_counts_enable_get': rz-mtu3-cnt.c:(.text+0xbec): undefined reference to `rz_mtu3_shared_reg_read' It seems better not to add the extra complexity here but instead just use a normal hard dependency, so remove the #else portion in the header along with the "|| COMPILE_TEST". This could also be fixed by having slightly more elaborate Kconfig dependencies or using the cursed 'IS_REACHABLE()' helper, but in practice it's already possible to compile-test all these drivers by enabling the mtd portion.

2023-08-18mfd: qcom-pm8xxx: Fix potential deadlock on &chip->pm_irq_lockChengfeng Ye1-4/+6
As &chip->pm_irq_lock is acquired by pm8xxx_irq_handler() under irq context, other process context code should disable irq before acquiring the lock. Since .irq_set_type and .irq_get_irqchip_state callbacks are generally executed from process context without irq disabled by default, the same lock acquision should disable irq. Possible deadlock scenario pm8xxx_irq_set_type() -> pm8xxx_config_irq() -> spin_lock(&chip->pm_irq_lock) <irq interrupt> -> pm8xxx_irq_handler() -> pm8xxx_irq_master_handler() -> pm8xxx_irq_block_handler() -> pm8xxx_read_block_irq() -> spin_lock(&chip->pm_irq_lock) (deadlock here) This flaw was found using an experimental static analysis tool we are developing for irq-related deadlock. Fix the potential deadlock by spin_lock_irqsave().

2023-08-18mfd: Explicitly include correct DT includesRob Herring51-66/+42
The DT of_device.h and of_platform.h date back to the separate of_platform_bus_type before it as merged into the regular platform bus. As part of that merge prepping Arm DT support 13 years ago, they "temporarily" include each other. They also include platform_device.h and of.h. As a result, there's a pretty much random mix of those include files used throughout the tree. In order to detangle these headers and replace the implicit includes with struct declarations, users need to explicitly include the correct includes.

This converts the STMPE MFD device tree bindings to the YAML schema. Reference the existing schema for the ADC, just define the other subnode schemas directly in the MFD schema. Add two examples so we have examples covering both the simple GPIO expander and the more complex with ADC and touchscreen. Some in-tree users do not follow the naming conventions for nodes so these DTS files need to be augmented to use proper node names like "adc", "pwm", "gpio", "keyboard-controller" etc before the bindings take effect on them.

It provides a high dynamic range, stereo DAC for headphone output, two integrated Class D amplifiers for loudspeakers, and two ADCs for wired headset microphone input or stereo line input. PDM inputs are provided for digital microphones. Add a YAML DT binding document for this device.

2023-08-17soundwire: bus: Allow SoundWire peripherals to register IRQ handlersLucas Tanure3-0/+53
Currently the in-band alerts for SoundWire peripherals can only be communicated to the driver through the interrupt_callback function. This however is slightly inconvenient for devices that wish to share IRQ handling code between SoundWire and I2C/SPI, the later would normally register an IRQ handler with the IRQ subsystem. However there is no reason the SoundWire in-band IRQs can not also be communicated as an actual IRQ to the driver. Add support for SoundWire peripherals to register a normal IRQ handler to receive SoundWire in-band alerts, allowing code to be shared across control buses. Note that we allow users to use both the interrupt_callback and the IRQ handler, this is useful for devices which must clear additional chip specific SoundWire registers that are not a part of the normal IRQ flow, or the SoundWire specification.

We just sorted the entries and fields last release, so just out of a perverse sense of curiosity, I decided to see if we can keep things ordered for even just one release. The answer is "No. No we cannot". I suggest that all kernel developers will need weekly training sessions, involving a lot of Big Bird and Sesame Street. And at the yearly maintainer summit, we will all sing the alphabet song together. I doubt I will keep doing this. At some point "perverse sense of curiosity" turns into just a cold dark place filled with sadness and despair.

Pull x86 fix from Thomas Gleixner: "A single fix for the mechanism to park CPUs with an INIT IPI. On shutdown or kexec, the kernel tries to park the non-boot CPUs with an INIT IPI. But the same code path is also used by the crash utility. If the CPU which panics is not the boot CPU then it sends an INIT IPI to the boot CPU which resets the machine. Prevent this by validating that the CPU which runs the stop mechanism is the boot CPU. If not, leave the other CPUs in HLT" * tag 'x86-core-2023-07-09' of git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip: x86/smp: Don't send INIT to boot CPU
