2013-01-14ARM: use clockevents_config_and_register() where possibleShawn Guo
The clockevent core is able to figure out the best mult and shift, calculate min_delta_ns and max_delta_ns, with the necessary info passed into clockevents_config_and_register(). Use this combined configure and register function where possible to make the codes less error prone and gain some positive diff stat.

2012-12-24ARM: delete struct sys_timerStephen Warren
Now that the only field in struct sys_timer is .init, delete the struct, and replace the machine descriptor .timer field with the initialization function itself. This will enable moving timer drivers into drivers/clocksource without having to place a public prototype of each struct sys_timer object into include/linux; the intent is to create a single of_clocksource_init() function that determines which timer driver to initialize by scanning the device dtree, much like the proposed irqchip_init() at: http://www.spinics.net/lists/arm-kernel/msg203686.html Includes mach-omap2 fixes from Igor Grinberg.

2011-12-18ARM: 7205/2: sched_clock: allow sched_clock to be selected at runtimeMarc Zyngier
sched_clock() is yet another blocker on the road to the single image. This patch implements an idea by Russell King: http://www.spinics.net/lists/linux-omap/msg49561.html Instead of asking the platform to implement both sched_clock() itself and the rollover callback, simply register a read() function, and let the ARM code care about sched_clock() itself, the conversion to ns and the rollover. sched_clock() uses this read() function as an indirection to the platform code. If the platform doesn't provide a read(), the code falls back to the jiffy counter (just like the default sched_clock). This allow some simplifications and possibly some footprint gain when multiple platforms are compiled in. Among the drawbacks, the removal of the *_fixed_sched_clock optimization which could negatively impact some platforms (sa1100, tegra, versatile and omap). Tested on 11MPCore, OMAP4 and Tegra.

This patch does a few simple cleanups of the ixp4xx timer and clocksource/clockevent code in mach-ixp4xx/common.c: - ixp4xx_clocksource_init() is static and always returns 0, which is ignored by its only caller: make it return void - ixp4xx_clockevent_init(): ditto - ixp4xx_get_cycles() is only referenced locally: make it static - use the ixp4xx_timer_irq.dev_id field to pass &clockevent_ixp4xx to ixp4xx_timer_interrupt() via its dev_id parameter, allowing the code in ixp4xx_timer_interrupt() to be smaller and faster Tested on an ixp420 machine (ds101).

2009-09-07IXP42x HSS support for setting internal clock rateKrzysztof Halasa
HSS usually uses external clocks, so it's not a big deal. Internal clock is used for direct DTE-DTE connections and when the DCE doesn't provide it's own clock. This also depends on the oscillator frequency. Intel seems to have calculated the clock register settings for 33.33 MHz (66.66 MHz timer base). Their settings seem quite suboptimal both in terms of average frequency (60 ppm is unacceptable for G.703 applications, their primary intended usage(?)) and jitter. Many (most?) platforms use a 33.333 MHz oscillator, a 10 ppm difference from Intel's base. Instead of creating static tables, I've created a procedure to program the HSS clock register. The register consists of 3 parts (A, B, C). The average frequency (= bit rate) is: 66.66x MHz / (A + (B + 1) / (C + 1)) The procedure aims at the closest average frequency, possibly at the cost of increased jitter. Nobody would be able to directly drive an unbufferred transmitter with a HSS anyway, and the frequency error is what it really counts. I've verified the above with an oscilloscope on IXP425. It seems IXP46x and possibly IXP43x use a bit different clock generation algorithm - it looks like the avg frequency is: (on IXP465) 66.66x MHz / (A + B / (C + 1)). Also they use much greater precomputed A and B - on IXP425 it would simply result in more jitter, but I don't know how does it work on IXP46x (perhaps 3 least significant bits aren't used?). Anyway it looks that they were aiming for exactly +60 ppm or -60 ppm, while <1 ppm is typically possible (with a synchronized clock, of course). The attached patch makes it possible to set almost any bit rate (my IXP425 533 MHz quits at > 22 Mb/s if a single port is used, and the minimum is ca. 65 Kb/s). This is independent of MVIP (multi-E1/T1 on one HSS) mode. Signed-off-by: Krzysztof Hałasa <khc@pm.waw.pl> Signed-off-by: David S. Miller <davem@davemloft.net>

2007-04-21[ARM] 4275/1: generic gpio layer for ixp4xxMilan Svoboda
This patch brings generic gpio layer support to ixp4xx. It creates functions needed for gpio->irq and irq->gpio translation. It expects and initial value to be passed to gpio_direction_output() which has been introduced by commit 28735a7253a6c24364765e80a5428b4a151fccc2 in Linus git tree. Generic gpio layer is going to be used by pxa2xx_udc driver. Signed-off-by: Milan Svoboda <msvoboda@ra.rockwell.com> Signed-off-by: Russell King <rmk+kernel@arm.linux.org.uk>

2006-12-07[ARM] 3985/1: ixp4xx clocksource cleanupKevin Hilman
Rather than using a device_initcall() for the clocksource initialization, just call the init from the sys_timer init function. Signed-off-by: Kevin Hilman <khilman@mvista.com> Signed-off-by: Russell King <rmk+kernel@arm.linux.org.uk>
2006-12-01[ARM] 3958/1: add platform device (pxa2xx-udc)to ixp4xxMilan Svoboda
Create include/asm-arm/arch-ixp4xx/udc.h and add platfrom device ixp4xx_udc_device into arch/arm/mach-ixp4xx/common.c. This allows us to use pxa2xx-udc on the ixp4xx platfrom. Both pxa2xx and ixp4xx use the same device controller. Signed-off-by:Milan Svoboda <msvoboda@ra.rockwell.com> Signed-off-by: Russell King <rmk+kernel@arm.linux.org.uk>
