Subject: [PATCH 0/5] i2c: davinci improvements and fixes
Date: Thu, 20 Nov 2014 12:03:03 +0200	[thread overview]
Message-ID: <1416477788-5544-1-git-send-email-grygorii.strashko@ti.com> (raw)

This series contains some fixes and improvements for Davinci I2C:
patch 1 - small improvement
patch 2 - fixes "Bus busy" state for some case (was reported long time ago:()

patch 3-5 - converts driver to use I2C bus recovery infrastructure and
adds Davinci I2C bus recovery mechanizm based on using ICPFUNC registers.
These patches are combination of two patches from Ben Gardiner [1] and
Mike Looijmans [2] which i've reworked to use I2C bus recovery infrastructure

"[PATCH 0/6] i2c-davinci gpio pulsed SCL recovery with ICPFUNC"

"[PATCH] i2c-davinci: Implement a bus recovery that actually works"

  i2c: i2c-davinci: switch to use platform_get_irq
  i2c: davinci: query STP always when NACK is received
  i2c: recovery: change input parameter to i2c_adapter for
    prepare/unprepare_recovery
  i2c: davinci: use bus recovery infrastructure
  i2c: davinci: use ICPFUNC to toggle I2C as gpio for bus recovery
