Subject: omap24xx_i2c: Handle OMAP5 like OMAP2,3,4
X-Git-Tag: v2013.01-rc2~59
X-Git-Url: https://git.sur5r.net/?a=commitdiff_plain;h=66839773a82cb56ebeb2b99322151f8a57a30efb;p=u-boot

omap24xx_i2c: Handle OMAP5 like OMAP2,3,4

OMAP5 has 8b i2c data register field, like OMAP2, 3 and 4. Handle in the same
way. This fixes the following error on OMAP5:

  OMAP5430 EVM # mmc rescan
  timed out in wait_for_bb: I2C_STAT=1410
  twl6035: could not turn on LDO9.
