git://git.pengutronix.de/git/imx/linux-2.6 into fixes From Sascha Hauer <s.hauer@pengutronix.de>: Two small ARM i.MX fixes for v3.9-rc - Fix i.MX25 DT compilation - Enable MAX clk on i.MX35 * tag 'arm-imx-fixes-for-3.9-rc' of git://git.pengutronix.de/git/imx/linux-2.6: ARM: i.MX35: enable MAX clock ARM: i.MX25: Fix DT compilation Signed-off-by: Arnd Bergmann <arnd@arndb.de>
2013-03-15ARM: i.MX35: enable MAX clockSascha Hauer1-0/+1
The i.MX35 has two bits per clock gate which are decoded as follows: 0b00 -> clock off 0b01 -> clock is on in run mode, off in wait/doze 0b10 -> clock is on in run/wait mode, off in doze 0b11 -> clock is always on The reset value for the MAX clock is 0b10. The MAX clock is needed by the SoC, yet unused in the Kernel, so the common clock framework will disable it during late init time. It will only disable clocks though which it detects as being turned on. This detection is made depending on the lower bit of the gate. If the reset value has been altered by the bootloader to 0b11 the clock framework will detect the clock as turned on, yet unused, hence it will turn it off and the system locks up. This patch turns the MAX clock on unconditionally making the Kernel independent of the bootloader. Signed-off-by: Sascha Hauer <s.hauer@pengutronix.de>

2013-03-04ARM: mach-imx: move early resume code out of the .data sectionNicolas Pitre2-24/+9
Building the kernel with allyesconfig fails because the i.mx early resume code located in the .data section is unable to fixup the bl relocation as the branch target gets too far away. The idea of having code in the .data section allows for easy access to nearby data using relative addressing while the MMU is off. However it is probably best to move the code back to the .text section where it belongs and fixup the data access instead. This solves the bl reloc issue (at least until this becomes a general problem) and simplifies the code as well.

Pull ARM SoC i.MX DT changes from Olof Johansson: "This branch contains of devicetree changes for the Freescale i.MX platform. The base patch of the branch changes the format of the dts files to a slightly different format that makes it easier to do derivative board definitions, but it also introduces a lot of churn in the process since every line of the file is touched. On top of that are a handful of the regular changes; enabling more boards as DT-based instead of legacy board files (mx25pdk), enabling another driver for devicetree and thus adding bindings (onewire), etc. I'm not happy about the churn, and will likely not take it for other platforms in the future." * tag 'late-dt' of git://git.kernel.org/pub/scm/linux/kernel/git/arm/arm-soc: (21 commits) ARM: dts: add dtsi for imx6q and imx6dl ARM: dts: rename imx6q.dtsi to imx6qdl.dtsi ARM: dts: i.MX6: Add regulator delay support ARM: dts: Add device tree entry for onewire master on i.MX53 ARM: i.MX53: Add clocks for i.mx53 onewire master.

Pull ARM SoC cleanups from Arnd Bergmann: "A large number of cleanups, all over the platforms. This is dominated largely by the Samsung platforms (s3c, s5p, exynos) and a few of the others moving code out of arch/arm into more appropriate subsystems. The clocksource and irqchip drivers are now abstracted to the point where platforms that are already cleaned up do not need to even specify the driver they use, it can all get configured from the device tree as we do for normal device drivers. The clocksource changes basically touch every single platform in the process. We further clean up the use of platform specific header files here, with the goal of turning more of the platforms over to being "multiplatform" enabled, which implies that they cannot expose their headers to architecture independent code any more. It is expected that no functional changes are part of the cleanup. The overall reduction in total code lines is mostly the result of removing broken and obsolete code." * tag 'cleanup' of git://git.kernel.org/pub/scm/linux/kernel/git/arm/arm-soc: (133 commits) ARM: mvebu: correct gated clock documentation ARM: kirkwood: add missing include for nsa310 ARM: exynos: move exynos4210-combiner to drivers/irqchip mfd: db8500-prcmu: update resource passing drivers/db8500-cpufreq: delete dangling include ARM: at91: remove NEOCORE 926 board sunxi: Cleanup the reset code and add meaningful registers defines ARM: S3C24XX: header mach/regs-mem.h local ARM: S3C24XX: header mach/regs-power.h local ARM: S3C24XX: header mach/regs-s3c2412-mem.h local ARM: S3C24XX: Remove plat-s3c24xx directory in arch/arm/ ARM: S3C24XX: transform s3c2443 subirqs into new structure ARM: S3C24XX: modify s3c2443 irq init to initialize all irqs ARM: S3C24XX: move s3c2443 irq code to irq.c ARM: S3C24XX: transform s3c2416 irqs into new structure ARM: S3C24XX: modify s3c2416 irq init to initialize all irqs ARM: S3C24XX: move s3c2416 irq init to common irq code ARM: S3C24XX: Modify s3c_irq_wake to use the hwirq property ARM: S3C24XX: Move irq syscore-ops to irq-pm clocksource: always define CLOCKSOURCE_OF_DECLARE ...

2013-02-05ARM: i.MX25: clk: parent per5_clk to AHB clockSteffen Trumtrar1-0/+3
The mxc-timer on the imx25 needs to be derived from the AHB clock. If a bootloader reparents this clock to the ipg_clk_highfreq, which according to the datasheet is a valid operation, the system can/will produce lockups/ freezes after some time [1]. This can be forced with code like while(1) syscall(SYS_clock_gettime, CLOCK_REALTIME, &tp); This was already fixed with the commit "i.MX25 GPT clock fix: ensure correct the clock source" [2], for 3.1-rc2, but was lost, when i.MX was converted to the common clock framework ("ARM i.MX25: implement clocks using common clock framework") [3] [1]: http://lists.arm.linux.org.uk/lurker/message/20130129.161230.229bda17.en.html [2]: 2012d9ca2a1381ae3e733330a7f0d1d2f1988bba [3]: 6bbaec5676e4f475b0d78743cbd4c70a8804ce14 Signed-off-by: Steffen Trumtrar <s.trumtrar@pengutronix.de> Cc: stable@vger.kernel.org # v3.5+ Signed-off-by: Sascha Hauer <s.hauer@pengutronix.de>

2013-01-30ARM: imx: return zero in case next event gets a large incrementShawn Guo1-1/+2
The return of v2_set_next_event() will lead to an infinite loop in tick_handle_oneshot_broadcast() - "goto again;" with imx6q WAIT mode (to be enabled). This happens because when global event did not expire any CPU local events, the broadcast device will be rearmed to a CPU local next_event, which could be far away from now and result in a max_delta_tick programming in set_next_event(). Fix the problem by detecting those next events with increments larger than 0x7fffffff, and simply return zero in that case. It leaves mx1_2_set_next_event() unchanged since only v2_set_next_event() will be running with imx6q WAIT mode support. Thanks Russell King for helping understand the problem.

As mach/hardware.h is deleted, we need to use platform_device_id to differentiate SoCs. Besides, one cpu_is_mx35 is useless as it has already used pdata to differentiate runtime Meanwhile we update the platform code accordingly.

2013-01-14ARM: use clockevents_config_and_register() where possibleShawn Guo2-24/+6
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.

2013-01-14ARM: imx: correct low-power mode settingShawn Guo2-0/+4
The hardware reset value of bit CCM_CLPCR_LPM enables WAIT mode (WAIT_UNCLOCKED) by default. However this is undesirable because WAIT mode should only be enabled when there is a driver managing ARM clock gating. Correct the initial power mode to WAIT_CLOCKED (disable WAIT mode). While at it, the power mode after resuming is also set back to WAIT_CLOCKED from STOP_POWER_OFF. Signed-off-by: Shawn Guo <shawn.guo@linaro.org>
2013-01-14ARM: imx: disable cpu in .cpu_kill hookShawn Guo3-4/+8
It's buggy to disable the cpu that is being hot-unplugged in .cpu_die hook which runs on the cpu itself. Instead, it should be done in .cpu_kill which runs on the thread (another cpu) that asks for shutting down the cpu. Move imx_enable_cpu(cpu, false) call into .cpu_kill hook, and leave the cpu to be hot-unplugged in WFI within .cpu_die, so that we can get a more stable cpu hot-plug operation.
