From 555b9ee1368a9ceddd5c963ad918db5120638674 Mon Sep 17 00:00:00 2001 From: Stefan Kristiansson Date: Mon, 29 Sep 2014 22:41:10 +0300 Subject: ASoC: ssm2602: add device tree bindings Allow the ssm2602/ssm2603/ssm2604 codec driver to be instantiated from the device tree. Also, add Kconfig prompts to allow manual selection of both the I2C and SPI configuration versions of the driver.
