From a78274b2050dcacc29561f4e35bdc91b896578cd Mon Sep 17 00:00:00 2001 From: Nishanth Menon Date: Thu, 1 Mar 2012 14:17:37 +0000 Subject: OMAP3+: Introduce generic logic for OMAP voltage controller OMAP Voltage controller is used to generically talk to PMICs on OMAP3,4,5 over I2C_SR. Instead of replicating code in multiple SoC code, introduce a common voltage controller logic which can be re-used from elsewhere. With this change, we replace setup_sri2c with omap_vc_init which has the same functionality, and replace the voltage scale replication in do_scale_vcore and do_scale_tps62361 with omap_vc_bypass_send_value. omap_vc_bypass_send_value can also now be used with any configuration of PMIC. NOTE: Voltage controller controlling I2C_SR is a write-only data path, so no register read operation can be implemented.
