From a8ef64e4ef6f5cabf083c8a8e5a181dceeea71ae Mon Sep 17 00:00:00 2001 From: =?UTF-8?q?Pali=20Roh=C3=A1r?= Date: Sat, 21 Nov 2020 23:30:11 +0100 Subject: [PATCH] Nokia RX-51: Decrease i2c speed to 100000 MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit It looks like that i2c bus lot of times timeout on some units. Prior migration to CONFIG_DM_I2C i2c speed was set to CONFIG_SYS_OMAP24_I2C_SPEED value which was 100000. Lower speed fixes timeout problems, so change speed back to its previous value.
