+-Info: Tunes the bcm2835-sdhost SD/MMC driver
+- N.B. This functionality is now available via the sd_* dtparams in the
+- base DTB.
+-Load: dtoverlay=sdtweak,<param>=<val>
+-Params: overclock_50 Clock (in MHz) to use when the MMC framework
+- requests 50MHz
+-
+- force_pio Disable DMA support (default off)
+-
+- pio_limit Number of blocks above which to use DMA
+- (default 1)
+-
+- debug Enable debug output (default off)
+-
+- poll_once Looks for a card once after booting. Useful
+- for network booting scenarios to avoid the
+- overhead of continuous polling. N.B. Using
+- this option restricts the system to using a
+- single card per boot (or none at all).
+- (default off)
+-
+- enable Set to off to completely disable the interface
+- (default on)
++Info: This overlay is now deprecated. Use the sd_* dtparams in the
++ base DTB, e.g. "dtoverlay=sdtweak,poll_once" becomes
++ "dtparam=sd_poll_once".
