      i2c: imx: Add arbitration lost check · 639a26cf
      Haibo Chen 提交于
      According to the i.mx spec, for multimaster mode, if I2C is
      enabled when the bus is busy and asserts start, hardware inhibits
      the transmission, clears MSTA without signaling a stop, generate
      an interrupt, and set I2C_I2SR[IAL] to indicate a failed attempt
      to engage the bus, which means arbitration lost. In this case,
      we should first test I2C_I2SR[IAL], and clear this bit if it is
      set, and then I2C controller default to slave receive mode.
      
      This patch check the IAL bit every time before an I2c transmission.
      if IAL is set, clear it and make I2C controller to default mode.

      i2c: move OF helpers into the core · 687b81d0
      Wolfram Sang 提交于
      I2C of helpers used to live in of_i2c.c but experience (from SPI) shows
      that it is much cleaner to have this in the core. This also removes a
      circular dependency between the helpers and the core, and so we can
      finally register child nodes in the core instead of doing this manually
      in each driver. So, fix the drivers and documentation, too.
