dt-bindings: PCI: amlogic: Fix the register name of the DBI region

2026-01-11T14:18:23+00:00

[ Upstream commit 4813dea9e272ba0a57c50b8d51d440dd8e3ccdd7 ] Binding incorrectly specifies the 'DBI' region as 'ELBI'. DBI is a must have region for DWC controllers as it has the Root Port and controller specific registers, while ELBI has optional registers. Hence, fix the binding. Though this is an ABI break, this change is needed to accurately describe the PCI memory map.

dt-bindings: pinctrl: toshiba,visconti: Fix number of items in groups

[ Upstream commit 316e361b5d2cdeb8d778983794a1c6eadcb26814 ] The "groups" property can hold multiple entries (e.g. toshiba/tmpv7708-rm-mbrc.dts file), so allow that by dropping incorrect type (pinmux-node.yaml schema already defines that as string-array) and adding constraints for items.

dt-bindings: phy: rockchip-inno-csi-dphy: make power-domains non-required

commit c254815b02673cc77a84103c4c0d6197bd90c0ef upstream. There are variants of the Rockchip Innosilicon CSI DPHY (e.g., the RK3568 variant) that are powered on by default as they are part of the ALIVE power domain. Remove 'power-domains' from the required properties in order to avoid false positives.

dt-bindings: serial: 8250: Make clocks and clock-frequency exclusive

2025-07-06T08:58:01+00:00

commit 09812134071b3941fb81def30b61ed36d3a5dfb5 upstream. The 8250 binding before converting to json-schema states, - clock-frequency : the input clock frequency for the UART or - clocks phandle to refer to the clk used as per Documentation/devicetree for clock-related properties, where "or" indicates these properties shouldn't exist at the same time. Additionally, the behavior of Linux's driver is strange when both clocks and clock-frequency are specified: it ignores clocks and obtains the frequency from clock-frequency, left the specified clocks unclaimed. It may even be disabled, which is undesired most of the time. But "anyOf" doesn't prevent these two properties from coexisting, as it considers the object valid as long as there's at LEAST one match. Let's switch to "oneOf" and disallows the other property if one exists, precisely matching the original binding and avoiding future confusion on the driver's behavior.

dt-bindings: i2c: nvidia,tegra20-i2c: Specify the required properties

commit 903cc7096db22f889d48e2cee8840709ce04fdac upstream. Specify the properties which are essential and which are not for the Tegra I2C driver to function correctly. This was not added correctly when the TXT binding was converted to yaml. All the existing DT nodes have these properties already and hence this does not break the ABI. dmas and dma-names which were specified as a must in the TXT binding is now made optional since the driver can work in PIO mode if dmas are missing.
