From 9ca8dbcc65cfc63d6f5ef3312a33184e1d726e00 Mon Sep 17 00:00:00 2001 From: Yunhong Jiang Date: Tue, 4 Aug 2015 12:17:53 -0700 Subject: Add the rt linux 4.1.3-rt3 as base Import the rt linux 4.1.3-rt3 as OPNFV kvm base. It's from git://git.kernel.org/pub/scm/linux/kernel/git/rt/linux-rt-devel.git linux-4.1.y-rt and the base is: commit 0917f823c59692d751951bf5ea699a2d1e2f26a2 Author: Sebastian Andrzej Siewior Date: Sat Jul 25 12:13:34 2015 +0200 Prepare v4.1.3-rt3 Signed-off-by: Sebastian Andrzej Siewior We lose all the git history this way and it's not good. We should apply another opnfv project repo in future.

MCP3021 is a successive approximation A/D +converter (ADC) with 10-bit resolution. The MCP3221 has 12-bit resolution. + +These devices provide one single-ended input with very low power consumption. +Communication to the MCP3021/MCP3221 is performed using a 2-wire I2C +compatible interface. Standard (100 kHz) and Fast (400 kHz) I2C modes are +available. The default I2C device address is 0x4d (contact the Microchip +factory for additional address options). -- cgit 1.2.3-korg
