[PATCH 0/3] mmc: Signal voltage switch procedure for UHS mode (sdhci)

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



This patchset is based on Johan's below patch series submitted recently:
  mmc: core: Add mmc_power_cycle
  mmc: core: Add card_busy to host_ops
  mmc: core: Fixup signal voltage switch

This patchset mainly update sdhci.c to co-work with Johan's above patches.
The first two patches are some update for the core stack with Johan's patch.
The third patch add the card_busy function and change the voltage_switch function in sdhci driver to work with the new code.

Kevin Liu (3):
 mmc: core: enhance the code for signal voltage setting
 mmc: core: cycle power the card in voltage switch rather than mmc_sd_get_cid
 mmc: sdhci: update signal voltage switch code
