[PATCH 1/3] i2c: at91: add setting HOLD field of TWIHS_CWGR via DT

2015-11-24 Thread Ludovic Desroches
From: Wenyou Yang Add the HOLD field management. Some i2c devices need a longer data hold time than the one given in the i2c bus specification. Since this value depends on the i2c device connected to the bus, add a DT property to configure it: "atmel,twd-hold-cycles". Signed-off-by: Wenyou Yang
