From b1c9390f0a44566f7cbd2db979e2ca5393767d49 Mon Sep 17 00:00:00 2001 From: Jon Hunter Date: Fri, 31 Oct 2025 10:37:40 +0000 Subject: [PATCH] Revert "rtc: tps6586x: Fix initial enable_irq/disable_irq balance" Commit 1502fe0e97be ("rtc: tps6586x: Fix initial enable_irq/disable_irq balance") breaks the wake-up alarm for the tps6586x. After this commit was added RTC wake ups from suspend stopped working on the Tegra20 Ventana platform. The problem is that this change set the 'irq_en' variable to true prior to calling devm_request_threaded_irq() to indicate that the IRQ is enabled, however, it was over looked that the flag IRQ_NOAUTOEN is already set meaning that the IRQ is not enabled by default. This prevents the IRQ from being enabled as expected. Revert this change to fix this.
