Adrian Hunter 4228b21390 mmc: sdhci: Remove SDHCI_SDR104_NEEDS_TUNING ... SDHCI_SDR104_NEEDS_TUNING was originally named SDHCI_HS200_NEEDS_TUNING and was added in commit 069c9f1428 ("mmc: host: Adds support for eMMC 4.5 HS200 mode"). That commit conflated SDHCI_SDR50_NEEDS_TUNING and SDHCI_HS200_NEEDS_TUNING due to what appears to be misplaced parentheses. Commit 156e14b126 ("mmc: sdhci: fix caps2 for HS200") made HS200 configuration equivalent to SDR104 configuration, renaming SDHCI_HS200_NEEDS_TUNING to SDHCI_SDR104_NEEDS_TUNING despite tuning for HS200 now being non-optional. The mix-up with SDHCI_SDR50_NEEDS_TUNING remained and became more obvious after commit 4b6f37d3a3 ("mmc: sdhci: clean up sdhci_execute_tuning() decision") where the author noted the patch was "reflecting what the original code was doing, it shows that it may not be what the author actually intended." The way the code is currently written, SDHCI_SDR104_NEEDS_TUNING causes tuning to be done always for SDR50 mode if SDR104 mode is also supported by the host controller. That makes no sense because we already have capabilities bit SDHCI_USE_SDR50_TUNING and corresponding flag SDHCI_SDR50_NEEDS_TUNING for that purpose. Given the dubious origins of SDHCI_SDR104_NEEDS_TUNING, it seems reasonable to remove it. The benefit being SDR50 mode will now not un-nessessarily do tuning.
