If we're not worried about the non-linearity of the 150R+120R+100R and 182R+150R+100R fan controllers (vs the 150R/100R/33R ones), these fan speed blocks could be collapsed into common.dtsi.

I know we're adding 15 boardsMore than 15 actually. Most .dts files support multiple devices. So there should be about 30 devices supported by these .dts files.quoted
, but this is, imho, over-fragmenting. I'm sure there's a reason you chose this path, but you haven't explained why in your commit log. So I'm left guessing...Synology seem to build there devices like lego. They have two different RTC blocks. They have three different fan alarm blocks, four different led blocks, etc. And to build a product, the just select a group of blocks and put them together.
The Ricoh RTC seems to be only used in the pre-2010 units. Everything else uses the Seiko 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 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. From http://forum.synology.com/wiki/index.php/What_kind_of_CPU_does_my_NAS_have, it doesn't look like there are any new 6281 or 6282 models for 2014.
The board setup code which Ben Peddell wrote has a somewhat similar structure: http://klightspeed.killerwolves.net/synology/linux-3.4-synology-0.1.patch
A more up-to-date version is at: http://klightspeed.killerwolves.net/synology/linux-3.7-synology-0.2.patch
It has a set of functions which add platform devices. And a table driven piece of code which based on the product name calls these functions to add the needed platform devices. Take a look at the table to get a better idea of the re-use factor of the blocks. In this DT version, i have a dtsi file for each function, and a dti file for each table entry. I will add to the changelog in the next version.
