-Subject: [PATCH 01/69] dtbindings: qcom_adm: Fix channel specifiers
-
-Original patch from Andy Gross.
-
-This patch removes the crci information from the dma
-channel property.  At least one client device requires
-using more than one CRCI value for a channel.  This does
-not match the current binding and the crci information
-needs to be removed.
-
-Instead, the client device will provide this information
-via other means.
