From c04df25a2560816e27bc10acb68f481a0ac6696f Mon Sep 17 00:00:00 2001 From: Wolfram Sang Date: Thu, 27 Feb 2025 14:42:56 +0100 Subject: [PATCH] rtc: sh: assign correct interrupts with DT [ Upstream commit 8f2efdbc303fe7baa83843d3290dd6ea5ba3276c ] The DT bindings for this driver define the interrupts in the order as they are numbered in the interrupt controller. The old platform_data, however, listed them in a different order. So, for DT based platforms, they are mixed up. Assign them specifically for DT, so we can keep the bindings stable. After the fix, 'rtctest' passes again on the Renesas Genmai board (RZ-A1 / R7S72100).
