From 2565d18de0c57d95b32686f11aa98fd40d8a7e26 Mon Sep 17 00:00:00 2001 From: Alison Wang <b18965@freescale.com> Date: Wed, 3 Dec 2014 15:00:46 +0800 Subject: [PATCH] ls102xa: qixis: Add CONFIG_QIXIS_I2C_ACCESS macro Through adding CONFIG_QIXIS_I2C_ACCESS macro, QIXIS_READ(reg)/QIXIS_WRITE(reg, value) can be used for both i2c and ifc access to QIXIS FPGA. This is more convenient for coding.
