From 0319bae9e72922f55dd34e90aedf14cf1dd93045 Mon Sep 17 00:00:00 2001 From: Christian Marangi Date: Tue, 1 Oct 2024 14:24:40 +0200 Subject: [PATCH] mtd: implement support for LED activity Implement support for LED activity. If the feature is enabled, make the defined ACTIVITY LED to signal mtd operations. LED activity is implemented HERE and not in the subsystem side to limit any performance degradation in case multiple call to MTD subsystem read/write are done.
