-Subject: [PATCH] bcm2835-i2s: Enable MMAP support via a DT property
-
-Code ported from bcm2708-i2s driver in Raspberry Pi tree.
-
-RPi commit 7ee829fd77a30127db5d0b3c7d79b8718166e568 ("bcm2708-i2s:
-Enable MMAP support via a DT property and overlay")
-
-The i2s driver used to claim to support MMAP, but that feature was disabled
-when some problems were found. Add the ability to enable this feature
-through Device Tree, using the i2s-mmap overlay.
-
-See: #1004
