| Subject: mmc: sdhci: Update the tuning failed messages to pr_debug level |
| |
| From: Faiz Abbas <faiz_abbas@ti.com> |
| |
| commit 2c92dd20304f505b6ef43d206fff21bda8f1f0ae upstream. |
| |
| 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. |
