* mfd: mc13xxx: Simplify device data fetching in probe()Biju Das2023-08-221-8/+1
| | | | | | | | | Simplify probe() by replacing of_match_device() and ID lookup for retrieving match data by i2c_get_match_data().

* mfd: rz-mtu3: Replace raw_spin_lock->spin_lock()Biju Das2023-08-221-8/+8
| | | | | | | | | | | | | | As per kernel documentation, use raw_spinlock_t only in real critical core code, low-level interrupt handling, and places where disabling preemption or interrupts is required. Here the lock is for concurrent register access from different drivers, hence spin_lock() is sufficient.

| | | | | | | | | | | | | | Reduce critical sections on rz_mtu3_start_stop_ch() and rz_mtu3_is_enabled() by moving offset and bitpos computation outside the critical section and drop the 'ret' variable on rz_mtu3_is_enabled() and return 'tstr & BIT(bitpos)' directly.

* mfd: qcom-pm8xxx: Fix potential deadlock on &chip->pm_irq_lockChengfeng Ye2023-08-181-4/+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().

* mfd: Explicitly include correct DT includesRob Herring2023-08-1850-64/+41
| | | | | | | | | | | | | | | 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 commit prepares a following commit for the regulator part of the MFD. The driver should support different device chips that differ in their register definitions, for instance to control LDOA1 and SWB2. So it is necessary to use a dedicated regulator description for a specific device variant. Thus, the content from DEVICEID Register 1 is used to choose a dedicated configuration between the different device variants.

|/ | | | | | | | | | | | | | | | The CS42L43 is an audio CODEC with integrated MIPI SoundWire interface (Version 1.2.1 compliant), I2C, SPI, and I2S/TDM interfaces designed for portable applications. 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. The MFD component registers and initialises the device and provides PM/system power management.
