Subject: [PATCH v4 16/18] I2C: OMAP1: set i2c unit feature implementation flags in platform data
Date: Wed,  1 Jun 2011 17:19:42 -0700	[thread overview]
Message-ID: <1306973984-15165-17-git-send-email-khilman@ti.com> (raw)
In-Reply-To: <1306973984-15165-1-git-send-email-khilman@ti.com>

From: Andy Green <andy@warmcat.com>

Most of the OMAP1 implementation flags are set statically, with the
exception that omap7xx has its data bus wired up differently.
