We need to have a way to do this runtime I think. The twl6040 comes up = with 100kbps as a default speed. So far we had no issue with 400kbps bus, bu= t if we increase it we might not be able to communicate with twl6040... --=20 P=E9ter -- To unsubscribe from this list: send the line "unsubscribe linux-omap" i= n the body of a message to majordomo@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html From mboxrd@z Thu Jan 1 00:00:00 1970 From: peter.ujfalusi@ti.com (Peter Ujfalusi) Date: Fri, 13 Jul 2012 12:20:38 +0200 Subject: [PATCH v2] ARM: OMAP4: twl-common: Support for additional devices on i2c1 bus In-Reply-To: References: <1342168682-15888-1-git-send-email-peter.ujfalusi@ti.com> Message-ID: <4FFFF676.1090304@ti.com> To: linux-arm-kernel@lists.infradead.org List-Id: linux-arm-kernel.lists.infradead.org On 07/13/2012 12:14 PM, Menon, Nishanth wrote: > We still need a way to switch to I2C highspeed mode > omap4_pmic_init still does register in 400KHz mode, while setting a bit in 6040 > should let us talk 3.3MHz on the bus.
