2023-11-01mfd: iqs62x: Annotate struct iqs62x_fw_blk with __counted_byKees Cook1-1/+1
Prepare for the coming implementation by GCC and Clang of the __counted_by attribute. Flexible array members annotated with __counted_by can have their accesses bounds-checked at run-time checking via CONFIG_UBSAN_BOUNDS (for array indexing) and CONFIG_FORTIFY_SOURCE (for strcpy/memcpy-family functions). As found with Coccinelle[1], add __counted_by for struct iqs62x_fw_blk.

2023-11-01mfd: stm32-timers: Add support for interruptsFabrice Gasnier1-0/+46
There are two types of STM32 timers that may have: - a global interrupt line - 4 dedicated interrupt lines. Those interrupts are optional as defined in the dt-bindings. Enforce checks on either one, four or no interrupts are provided with their names. Optionally get them here, to be used by child devices.

2023-11-01mfd: wcd934x: Update to use maple tree register cacheMark Brown1-1/+1
The maple tree register cache is based on a much more modern data structure than the rbtree cache and makes optimisation choices which are probably more appropriate for modern systems than those made by the rbtree cache. In v6.5 it has also acquired the ability to generate multi-register writes in sync operations, bringing performance up to parity with the rbtree cache there. Update the wcd934x to use the more modern data structure. Signed-off-by: Mark Brown <[email protected]> Link: https://lore.kernel.org/r/[email protected] Signed-off-by: Lee Jones <[email protected]>
2023-11-01mfd: axp20x: Generalise handling without interruptAndre Przywara1-20/+24
At the moment we allow the AXP15060 and the AXP806 PMICs to omit the interrupt line to the SoC, and we skip registering the PEK (power key) driver in this case, since that crashes when no IRQ is described in the DT node. The IRQ pin potentially not being connected to anything does affect more PMICs, though, and the PEK driver is not the only one requiring an interrupt: at least the AC power supply driver crashes in a similar fashion. Generalise the handling of AXP MFD devices when the platform tables describe no interrupt, by allowing each device to specify an alternative MFD list for this case. If no specific alternative is specified, we go with the safe default of "just the regulators", which matches the current situation. This enables new devices using the AXP313a PMIC, but not connecting the IRQ pin.

2023-08-18mfd: cs47l85: Update to use maple tree register cacheMark Brown1-4/+4
The maple tree register cache is based on a much more modern data structure than the rbtree cache and makes optimisation choices which are probably more appropriate for modern systems than those made by the rbtree cache. In v6.5 it has also acquired the ability to generate multi-register writes in sync operations, bringing performance up to parity with the rbtree cache there. Update the cs47l85 driver to use the more modern data structure.
