From 44140b3c57b0df88b60c618c10a829cebec45712 Mon Sep 17 00:00:00 2001 From: Vic Yang Date: Mon, 27 Feb 2012 14:08:02 -0800 Subject: EC_LPC_COMMAND_PWM_GET_FAN_RPM return target RPM Actual RPM is now read from LPC mapped space. Modify this command to return target RPM so we can verify EC receives target RPM. Signed-off-by: Vic Yang BUG=chrome-os-partner:8238 TEST=Get the same value after setting target RPM.
