[tip:x86/platform] x86: Add TS-5500 platform support
Commit-ID: 7d0291256ca99cbb6124f63228003329e7a64b21 Gitweb: http://git.kernel.org/tip/7d0291256ca99cbb6124f63228003329e7a64b21 Author: Vivien Didelot AuthorDate: Fri, 4 Jan 2013 16:18:14 -0500 Committer: Ingo Molnar CommitDate: Fri, 25 Jan 2013 19:40:23 +0100 x86: Add TS-5500 platform support The Technologic Systems TS-5500 is an x86-based (AMD Elan SC520) single board computer. This driver registers most of its devices and exposes sysfs attributes for information such as jumpers' state or presence of some of its options. This driver currently registers the TS-5500 platform, its on-board LED, 2 pin blocks (GPIO) and its analog/digital converter. It can be extended to support other Technologic Systems products, such as the TS-5600. Signed-off-by: Vivien Didelot Acked-by: Thomas Gleixner Cc: Savoir-faire Linux Inc.

I think the attached config might not be the right one. This issue happens when the ts5500 support is selected (CONFIG_TS5500=y) but the LED class (CONFIG_NEW_LEDS and CONFIG_LEDS_CLASS) is not. Thanks for pointing this out. The following patch below solves this issue. Is it ok, or should I resend to whole board support patch?
