Linus Torvalds
25c456dab5
Pull MFD updates from Lee Jones:
"Core:
- Add a resource-managed version of alloc_workqueue()
(`devm_alloc_workqueue()`)
- Preserve the Open Firmware (OF) node when an ACPI handle
is present
Apple SMC:
- Wire up the Apple SMC power driver by adding a new MFD cell
Atmel HLCDC:
- Fetch the LVDS PLL clock as a fallback if the generic sys_clk
is unavailable
Broadcom BCM2835 PM:
- Add support for the BCM2712 power management device
- Introduce a hardware type identifier to distinguish SoC variants
Congatec CGBC, KEMPLD, RSMU, Si476x:
- Fix various kernel-doc warnings and correct struct member names
DLN2:
- Drop redundant USB device references and switch to managed
resource allocations
- Update bare 'unsigned' types to 'unsigned int'
ENE KB3930:
- Use the of_device_is_system_power_controller() wrapper
EZX PCAP:
- Avoid rescheduling after destroying the workqueue by switching
to a device-managed workqueue
- Drop redundant memory allocation error messages
- Return directly instead of using empty goto statements
Freescale i.MX25 TSADC:
- Convert devicetree bindings from TXT to YAML format
Freescale MC13xxx:
- Fix a memory leak in subdevice platform data allocation by
using devm_kmemdup()
Intel LPC ICH:
- Expose a software node for the GPIO controller cell to fix
GPIO lookups
Intel LPSS:
- Add PCI IDs for the Intel Nova Lake-H platform
Maxim MAX77620:
- Convert devicetree bindings from TXT to YAML format
- Document an optional I2C address for the MAX77663 RTC device
Maxim MAX77705:
- Make the max77705_pm_ops variable static to resolve a
sparse warning
MediaTek MT6397:
- Correct the hardware CIDs for the MT6328, MT6331, and MT6332
PMICs to allow proper driver binding
ROHM BD71828:
- Enable system wakeup via the power button
ROHM BD72720:
- Add a new compatible string for the ROHM BD73900 PMIC
SpacemiT P1:
- Drop the deprecated "vin-supply" property from the devicetree
bindings
- Add individual regulator supply properties to match actual
hardware topology
STMicroelectronics STPMIC1:
- Attempt system shutdown a second time to handle transient I2C
communication failures
Viperboard:
- Drop redundant USB device references"
