-Subject: [PATCH 141/170] BCM270X_DT: Disable DMA for bcm2835-sdhost on Pi2
-
-This is an interim patch to verify that problems seen with
-some cards can be worked around at the expense of an increased
-CPU load by forcing PIO mode.
-
-Although this could have used the brcm,force-pio attribute, that
-is a boolean (true if present, false if absent) and attributes
-can't be deleted by overlays. Instead, make brcm,pio-limit
-unfeasibly high instead to allow DMA to be re-enabled using the
-pio_limit parameter of the sdhost or sdtweak overlays.
