From 385c9ef5a7215b2b0c22836fee6c692dfc8559d7 Mon Sep 17 00:00:00 2001 From: Heiko Schocher Date: Mon, 16 Jan 2012 21:12:23 +0000 Subject: [PATCH 01/15] i2c: add i2c_core and prepare for new multibus support This Patch introduce the new i2c_core file, which holds the I2C core functions, for the rework of the multibus/ multiadapter support. Also adds changes in i2c.h for the new I2C multibus/multiadapter support. This new support can be activated with the CONFIG_SYS_I2C define.

9a2accb44f871af9c87c34d1c9ac95010f4e6f09 Mon Sep 17 00:00:00 2001 From: Heiko Schocher Date: Thu, 25 Oct 2012 10:32:14 +0200 Subject: [PATCH 05/15] i2c, multibus: get rid of CONFIG_I2C_MUX CONFIG_I2C_MUX is replaced through the new i2c multibus/multiadapter framework, configured through CONFIG_SYS_I2C. As CONFIG_I2C_MUX is only used on the keymile boards, and they are now completely moved to the new framework, remove CONFIG_I2C_MUX.

the new I2C framework we need to adapt the u-boot update function. Due to the new framework all i2c leafs behind a mux are present in the system and not only those who are defined and used. So it is bus number 5 after the rework.

There are some differences between i.MX6 and Vybrid for I2C controller. (1) The registers' offset are different. (2) The I2C clock divider values are different. (3) In I2C control register, the enable/disable/reset bit is inverted for Vybrid comparing to i.MX6. (4) In I2C status register, the interrupt flag bit is cleared by writing "1" for Vybrid. For i.MX6, this bit is cleared by writing "0". (5) In I2C status register, the arbitration lost flag bit is cleared by writing "1" for Vybrid. For i.MX6, this bit is cleared by writing "0".
