mmc: sdhci: add support for retuning mode 1 2011-05-25T03:53:48+00:00 Arindam Nath arindam.nath@amd.com 2011-05-05T06:49:07+00:00 cf2b5eea1ea0ff9b3184bc6771bcb93a9fdcd1d9 Host Controller v3.00 can support retuning modes 1,2 or 3 depending on the bits 46-47 of the Capabilities register. Also, the timer count for retuning is indicated by bits 40-43 of the same register. We initialize timer_list for retuning the first time we execute tuning procedure. This condition is indicated by SDHCI_NEEDS_RETUNING not being set. Since retuning mode 1 sets a limit of 4MB on the maximum data length, we set max_blk_count appropriately. Once the tuning timer expires, we set SDHCI_NEEDS_RETUNING flag, and if the flag is set, we execute tuning procedure before sending the next command. We need to restore mmc_request structure after executing retuning procedure since host->mrq is used inside the procedure to send CMD19. We also disable and re-enable this flag during suspend and resume respectively, as per the spec v3.00. Tested by Zhangfei Gao with a Toshiba uhs card and general hs card, on mmp2 in SDMA mode.
