My attempt to make the LEDs only compile for RealView and
Versatile was futile: I missed the Versatile Express. So invert
the logic and explicitly include the platforms to compile for.

ARM: 6235/2: driver for the LEDs found in the later ARM refdesigns 2010-07-26T09:48:29+00:00 Linus Walleij linus.walleij@stericsson.com 2010-07-20T21:32:00+00:00 b5417019a6e614f5285f9eb8f9e5b2d62395965b This adds a simple driver supporting the new LED framework with triggers and all for the RealView and Versatile platforms. The RealView and Versatile platform drivers were arranged to compile for all-but-integrator as a side effect since the Integrator has a different LED driver.

ARM: Realview/Versatile: remove useless TIMER_RELOAD calculations 2010-05-02T08:35:34+00:00 Russell King rmk+kernel@arm.linux.org.uk 2010-01-14T22:37:12+00:00 fe8e1a57f0ccdaede41618ca9ced7d746b6298d3 Realview/Versatile copied the Integrator timer code, including the calculations for ensuring that the reload value fits into the 16-bit counter. However, these platforms have a 32-bit counter which is clocked at a slower rate. The result is that the preprocessor conditions are never triggered: TICKS_PER_uSEC = 1, mSEC_10 = 10000, which is 0x2710 - less than 0x10000. So, remove the unnecessary complexity, reducing the TIMER_RELOAD calculation to just: TICKS_PER_uSEC * mSEC_10 Signed-off-by: Russell King <rmk+kernel@arm.linux.org.uk> 
Realview/Versatile copied the Integrator timer code, including the
calculations for ensuring that the reload value fits into the 16-bit
counter.  However, these platforms have a 32-bit counter which is
clocked at a slower rate.

The result is that the preprocessor conditions are never triggered:
TICKS_PER_uSEC = 1, mSEC_10 = 10000, which is 0x2710 - less than
0x10000.

So, remove the unnecessary complexity, reducing the TIMER_RELOAD
calculation to just:

	TICKS_PER_uSEC * mSEC_10
