From 4071318983ff2dead7fd2caf85498bcd8956d93e Mon Sep 17 00:00:00 2001 From: Thara Gopinath Date: Tue, 15 Feb 2011 13:28:58 +0530 Subject: OMAP3: PM: Set/clear T2 bit for Smartreflex on TWL Voltage control on TWL can be done using VMODE/I2C1/I2C_SR. Since almost all platforms use I2C_SR on omap3, omap3_twl_init by default expects that OMAP's I2C_SR is plugged in to TWL's I2C and calls omap3_twl_set_sr_bit. On platforms where I2C_SR is not connected, the board files are expected to call omap3_twl_set_sr_bit(false) to ensure that I2C_SR path is not set for voltage control and prevent the default behavior of omap3_twl_init.
