From 9f0346dcbea363787186c94ef94dd01aaa215afa Mon Sep 17 00:00:00 2001 From: Linus Torvalds Date: Sat, 5 Sep 2026 11:59:05 -0700 Subject: Merge tag 'driver-core-7.3-rc2' of git://git.kernel.org/pub/scm/linux/kernel/git/driver-core/driver-core Pull driver core fixes from Danilo Krummrich: - Fix kernfs listxattr() not returning security xattr names (e.g. SELinux labels) when the kernfs node has no allocated kernfs_iattrs - Fix silent truncation of IRQ vector indices in the Rust PCI abstractions - Don't select OF from DRIVER_PE_KUNIT_TEST; skip the test when OF is disabled instead of silently enabling extra kernel functionality - Russ Weight is retiring from kernel development; update the Firmware Loader sysfs contact to the driver-core mailing list, add a CREDITS entry for Firmware Upload, and update MAINTAINERS accordingly * tag 'driver-core-7.3-rc2' of git://git.kernel.org/pub/scm/linux/kernel/git/driver-core/driver-core: MAINTAINERS: Remove Russ Weight from Firmware Loader CREDITS: Add CREDITS entry for Firmware Upload firmware_loader: Change contact for sysfs nodes rust: pci: reject IRQ vector indices that do not fit in u32 kernfs: preserve security xattrs without allocating iattrs drivers: base: test: DRIVER_PE_KUNIT_TEST should not select OF --- .../trigger-source/adi,util-sigma-delta-spi.yaml | 49 ++++++++++++++++++++++ .../bindings/trigger-source/gpio-trigger.yaml | 40 ++++++++++++++++++ .../bindings/trigger-source/pwm-trigger.yaml | 37 ++++++++++++++++ 3 files changed, 126 insertions(+) create mode 100644 Documentation/devicetree/bindings/trigger-source/adi,util-sigma-delta-spi.yaml create mode 100644 Documentation/devicetree/bindings/trigger-source/gpio-trigger.yaml create mode 100644 Documentation/devicetree/bindings/trigger-source/pwm-trigger.yaml (limited to 'Documentation/devicetree/bindings/trigger-source') diff --git a/Documentation/devicetree/bindings/trigger-source/adi,util-sigma-delta-spi.yaml b/Documentation/devicetree/bindings/trigger-source/adi,util-sigma-delta-spi.yaml new file mode 100644 index 000000000..ea4661795 --- /dev/null +++ b/Documentation/devicetree/bindings/trigger-source/adi,util-sigma-delta-spi.yaml @@ -0,0 +1,49 @@ +# SPDX-License-Identifier: (GPL-2.0-only OR BSD-2-Clause) +# Copyright (c) 2025 Analog Devices, Inc. +# Copyright (c) 2025 BayLibre, SAS + +%YAML 1.2 +--- +$id: http://devicetree.org/schemas/trigger-source/adi,util-sigma-delta-spi.yaml# +$schema: http://devicetree.org/meta-schemas/core.yaml# + +title: Analog Devices Util Sigma-Delta SPI IP Core + +maintainers: + - David Lechner + +description: + The Util Sigma-Delta SPI is an FPGA IP core from Analog Devices that provides + a SPI offload trigger from the RDY signal of the combined DOUT/RDY pin of + the sigma-delta family of ADCs. + https://analogdevicesinc.github.io/hdl/library/util_sigma_delta_spi/index.html + +properties: + compatible: + const: adi,util-sigma-delta-spi + + reg: + maxItems: 1 + + clocks: + maxItems: 1 + + '#trigger-source-cells': + const: 0 + +required: + - compatible + - reg + - clocks + - '#trigger-source-cells' + +additionalProperties: false + +examples: + - | + trigger@40000 { + reg = <0x40000 0x1000>;
