From 4e2d93de070ceaca5097f7ee5c311731b83208a0 Mon Sep 17 00:00:00 2001 From: Jarkko Nikula Date: Wed, 9 Aug 2017 15:24:44 +0300 Subject: i2c: designware: Fix standard mode speed when configuring the slave mode Code sets bit DW_IC_CON_SPEED_FAST (0x4) always when configuring the slave mode. This results incorrect register value DW_IC_CON_SPEED_HIGH (0x6) when OR'ed together with DW_IC_CON_SPEED_STD (0x2). Remove this and let the code set the speed mode bits according to clock frequency or default to fast mode.
