[PATCH 0/7] at91 add i2c-gpio suport

[Jean-Christophe PLAGNIOL-VILLARD]

Hi,

	This paatch serie add the i2c suport to at91 using the i2c-gpio as teh
	IP is broken until the sam9x5. For the sam9x5 untill we have the hw
	driver support use the i2c-gpio too

	on the sam9x5ek enable the i2c and the qt1070

	This patch serie depends on i2c qt1070 patch and the at91sam9x5ek
	1-wire one

The following changes since commit 3a5609a37a19b0b6b5f4c61e3c561b7bf2d25b72:

  i2c: add versatile support (2012-11-01 06:58:21 +0800)
