From db85474594609fc6f6a37fe5d5001fa9341971ed Mon Sep 17 00:00:00 2001 From: Krzysztof Kozlowski Date: Wed, 6 Apr 2022 17:40:50 +0200 Subject: [PATCH 1/2] dt-bindings: soc: samsung: usi: refer to dtschema for SPI After adding DT schema for Samsung SPI controller, the Samsung USI bindings can reference it directly for proper schema validation.

However the Exynos4210 flavor actually differs by number of interrupts. Add new compatibles, maintaining backward compatibility with Exynos4210, and constraints for number of interrupts. This allows to exactly match the Exynos MCT hardware.
