This patch series introduces a new tuning algorithm for mmc. The new algorithm should be used when delay chain is enabled. The ITAPDLY is selected from the largest passing window and the buffer is not viewed as a circular buffer. The new tuning algorithm is implemented as per the paper published here [0] and has been tested on the following platforms: AM62x SK, AM62A SK, AM62p SK, AM64x SK, and AM64x EVM. The series also includes a few fixes in the sdhci_am654 driver on OTAPDLYEN/ITAPDLYEN and ITAPDELSEL.
