Pull MFD updates from Lee Jones:
"Core Frameworks:
- Allow all MFD Cell properties to be filled in dynamically at
runtime
- Skip disabled device nodes and continue to look for subsequent
devices
New Device Support:
- Add support for Lunar Lake-M PCI to Intel LPSS PCI
- Add support for Denverton to Intel ICH LPC
New Functionality:
- Add support for Clocks to Texas Instruments TWL* Core
- Add support for Interrupts to STMicroelectronics STM32 Timers
Fix-ups:
- Convert to new devm-* (managed) power-off API
- Remove superfluous code
- Bunch of Device Tree additions, conversions and adaptions
- Simplify obtaining resources (memory, device data) using unified
API helpers
- Trivial coding-style / spelling type clean-ups
- Constify / staticify changes
- Expand or edit on existing documentation
- Convert some Regmap configurations to use the Maple Tree cache
- Apply new __counted_by() annotation to several data structures
containing flexible arrays
- Replace strncpy() with strscpy()
Bug Fixes:
- Remove double put creating reference imbalances
- Ensure headphone/lineout detection gets set when booting with ACPI"

title: System Controller Registers R/W
|
|
|
|
description: |
|
|
System controller node represents a register region containing a set
|
|
of miscellaneous registers. The registers are not cohesive enough to
|
|
represent as any specific type of device. The typical use-case is
|
|
for some other node's driver, or platform-specific code, to acquire
|
|
a reference to the syscon node (e.g. by phandle, node path, or
|
|
search using a specific compatible value), interrogate the node (or
|
|
associated OS driver) to determine the location of the registers,
|
|
and access the registers directly.
