From 2d0a7addbd109bd4a586d2ae2914a0047a4719de Mon Sep 17 00:00:00 2001 From: Ben Peddell Date: Thu, 20 Feb 2014 06:02:37 +1000 Subject: ARM: Kirkwood: Add support for many Synology NAS devices Add device tree fragments and files to support many of the kirkwood based Synology NAS devices. This is a modification of Andrew Lunn's translation of the board setup file maintained by Ben Peddell The Ricoh RS5C372 RTC was used in all 2009 units and some 2010 units. All other Synology Kirkwood-based DiskStations and RackStations use the Seiko S35390A RTC. Most of the 1-bay and 2-bay units use the GPIOs that are multiplexed with the built-in SATA interface activity/presence pins on mpp 20-23, while the 4-bay units use ge01 and a PCIe SATA controller, and put the software controlled HDD leds on mpp 36-43. Most of the 6281 units with HDD power controls use mpp 29 and 31, while most of the 6282 units with HDD power controls use mpp 30, 34, 44 and 45 and provide a model ID on mpp 28, 29, 46 and 47. Pre-2012 units and most 4-bay units didn't have a separate power control for HDD1. These power controls are presumably to limit startup current from the 12V brick power supply. Instead of using separate dtsi files in a synology directory, this patch uses a single dtsi file containing all of the modules for these boards, with all of the modules not common to all boards disabled. The board dts files then enable the appropriate modules for their boards.
