From c67f2d8a4b7f23da8d46202135485a3ea9308fb2 Mon Sep 17 00:00:00 2001 From: Faiz Abbas Date: Fri, 6 Dec 2019 17:13:26 +0530 Subject: [PATCH] mmc: sdhci: Update the tuning failed messages to pr_debug level [ Upstream commit 2c92dd20304f505b6ef43d206fff21bda8f1f0ae ] Tuning support in DDR50 speed mode was added in SD Specifications Part1 Physical Layer Specification v3.01. Its not possible to distinguish between v3.00 and v3.01 from the SCR and that is why since commit 4324f6de6d2e ("mmc: core: enable CMD19 tuning for DDR50 mode") tuning failures are ignored in DDR50 speed mode. Cards compatible with v3.00 don't respond to CMD19 in DDR50 and this error gets printed during enumeration and also if retune is triggered at any time during operation. Update the printk level to pr_debug so that these errors don't lead to false error reports.
