From 0306741004fdfc2bc515b4b129b1f86881c5fcf5 Mon Sep 17 00:00:00 2001 From: Sylwester Nawrocki Date: Thu, 4 Aug 2016 15:38:41 +0200 Subject: ASoC: L3 bus: Add default gpio ops This adds aptional GPIO bit-bang based callback implementations for setting CLK, DATA and MODE L3 bus lines. It is added here to avoid possible duplicate implementations across users of the bus.
