Tegra host supports HW busy detection and timeouts based on the count programmed in SDHCI_TIMEOUT_CONTROL register and max busy timeout it supports is 11s in finite busy wait mode. Some operations like SLEEP_AWAKE, ERASE and flush cache through SWITCH commands take longer than 11s and Tegra host supports infinite HW busy wait mode where HW waits forever till the card is busy without HW timeout. This patch implements Tegra specific set_timeout sdhci_ops to allow switching between finite and infinite HW busy detection wait modes based on the device command expected operation time.
