dt-bindings: auxdisplay: ht16k33: Use unevaluatedProperties to fix common property warning

[ Upstream commit 398c0c8bbc8f5a9d2f43863275a427a9d3720b6f ] Change additionalProperties to unevaluatedProperties because it refs to /schemas/input/matrix-keymap.yaml.

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

2026-01-19T12:09:27+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.

Lists should have fixed constraints, because binding must be specific in respect to hardware, thus add missing constraints to number of clocks.

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

2025-07-10T13:57:39+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.

[ Upstream commit 6856edf7ead8c54803216a38a7b227bcb3dadff7 ] The sense resistor used for measuring currents is typically some tens of milli Ohms. It has accidentally been documented to be tens of mega Ohms. Fix the size of this resistor and a few copy-paste errors while at it. Drop the unsuitable 'rohm,charger-sense-resistor-ohms' property (which can't represent resistors smaller than one Ohm), and introduce a new 'rohm,charger-sense-resistor-micro-ohms' property with appropriate minimum, maximum and default values instead.
