dt-bindings: gpio: fix microchip #interrupt-cells

2026-04-11T12:16:25+00:00

[ Upstream commit 6b5ef8c88854b343b733b574ea8754c9dab61f41 ] The GPIO controller on PolarFire SoC supports more than one type of interrupt and needs two interrupt cells.

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

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

2025-12-06T21:12:40+00:00

[ 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. This fixes dtbs_check warnings like: toshiba/tmpv7708-rm-mbrc.dtb: pinctrl@24190000 (toshiba,tmpv7708-pinctrl): pwm-pins:groups: ['pwm0_gpio16_grp', 'pwm1_gpio17_grp', 'pwm2_gpio18_grp', 'pwm3_gpio19_grp'] is too long Fixes: 1825c1fe0057 ("pinctrl: Add DT bindings for Toshiba Visconti TMPV7700 SoC") Cc: stable@vger.kernel.org Signed-off-by: Krzysztof Kozlowski Acked-by: Conor Dooley Signed-off-by: Linus Walleij [ adjusted $ref context ] Signed-off-by: Sasha Levin Signed-off-by: Greg Kroah-Hartman

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.

commit ee047e1d85d73496541c54bd4f432c9464e13e65 upstream. Lists should have fixed constraints, because binding must be specific in respect to hardware, thus add missing constraints to number of clocks.

commit 2558df8c13ae3bd6c303b28f240ceb0189519c91 upstream. 'minItems' alone does not impose upper bound, unlike 'maxItems' which implies lower bound.
