2011-02-19ARM: rationalize versatile family Kconfig/MakefileRussell King2-7/+11
Move leds and sched_clock build conditionals out of the Makefile into the Kconfig file. Move selection of HAVE_SCHED_CLOCK into the platform Kconfig rather than duplicating it three times in the main architecture Kconfig.

2011-02-19ARM: add versatile family consolidated CLCD supportRussell King4-0/+198
This consolidates the CLCD panel definitions and memory allocation into one location. Rename the Sanyo 2.5in and Epson 2.2in displays after their respective part numbers. Rather than using a general "Sanyo 2.5in" and "Epson 2.2in" description of the display panel, use the manufacturers part number to be more specific. This helps people identify what the timings actually refer to, which are panel specific. While here, add CLCD capability information to each panel definition, which has no effect until we add the board-level capabilities.

2011-01-05ARM: vexpress: add sched_clock() for Versatile ExpressRussell King1-2/+3
Add a sched_clock() implementation to Versatile Express using the new sched_clock() infrastructure for extending 32bit counters to full 64-bit nanoseconds. Tested-by: Will Deacon <will.deacon@arm.com> Signed-off-by: Russell King <rmk+kernel@arm.linux.org.uk>
2010-12-22ARM: versatile: convert sched_clock() to use new infrastructureRussell King2-22/+32
Convert versatile platforms to use the new sched_clock() infrastructure for extending 32bit counters to full 64-bit nanoseconds. Tested-by: Will Deacon <will.deacon@arm.com> Signed-off-by: Russell King <rmk+kernel@arm.linux.org.uk>
2010-12-22ARM: ensure all sched_clock() implementations are notrace markedRussell King1-1/+1
ftrace requires sched_clock() to be notrace. Ensure that all implementations are so marked. Also make sure that they include linux/sched.h Also ensure OMAP clocksource read functions are marked notrace as they're used for sched_clock() too.

2010-12-22ARM: realview/versatile: update clock source registrationRussell King1-3/+1
In d7e81c2 (clocksource: Add clocksource_register_hz/khz interface) new interfaces were added which simplify (and optimize) the selection of the divisor shift/mult constants. Switch over to using this new interface. Tested-by: Will Deacon <will.deacon@arm.com> Signed-off-by: Russell King <rmk+kernel@arm.linux.org.uk>

From: Rob Herring <rob.herring@smooth-stone.com> The timer-sp h/w used on versatile platforms can also be used for other platforms, so move it to a common location. Signed-off-by: Rob Herring <rob.herring@smooth-stone.com> Signed-off-by: Russell King <rmk+kernel@arm.linux.org.uk>
2010-07-26ARM: 6264/1: fix Versatile Express LED oversightLinus Walleij1-4/+5
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. Signed-off-by: Linus Walleij <triad@df.lth.se> Signed-off-by: Russell King <rmk+kernel@arm.linux.org.uk>
2010-07-26ARM: 6235/2: driver for the LEDs found in the later ARM refdesignsLinus Walleij2-2/+108
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.

2010-05-02ARM: Realview/Versatile: remove useless TIMER_RELOAD calculationsRussell King1-11/+1
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>
