Hello, As far as I know, the Secure Digital Host Controller do support to wait while the card signals busy. There is a capability MMC_CAP_WAIT_WHILE_BUSY which utilizes this and will significantly improve performances during certain operations like resume, switch etc.
If this capability is not defined then it will be replaced by msleep for maximum timeout value according to operation being performed. I am wondering why can't we utilize by enabling this capability in sdhci.c (or) This was considered and there were some corner case bugs and hence rejected to define? Any thoughts/answers?
