* ARM: dts: DRA7: Add PMU nodesLucas Weaver2014-09-182-0/+11
| | | | | | | | | | | | | | DRA74x and DRA72x family of processors vary slightly in the number of CPUs. So, add different instances of PMU for each of these processor groups. Further, since the interrupts bypass crossbar and are directly connected to GIC, mark the dts nodes with relevant information. Tested with perf utility.

* ARM: dts: Enable PMIC idle configuration for LDPTony Lindgren2014-09-181-0/+5
| | | | | | | | | | | With the IO chain reconfigure fixed, we can now enable the PMIC scripts for LDP. Note that at least on my es3.0 based LDP, the UART seems to be flakey after wake-up events from off-idle and hangs but eventually continues. Signed-off-by: Tony Lindgren <tony@atomide.com>
* ARM: dts: Add support for Ethernet on some N900 macro boardsTony Lindgren2014-09-182-0/+45
| | | | | | | | | | | | | | | As we have support for this in board-rx51-peripherals.c, let's add it to the .dts files too. Note that the reset GPIO will eventually go to the driver. For now let's just pull it down and skip any further reset in case the bootloader has configured the MAC address so NFSroot works. Also note that after 3430-sdp are using proper GPMC timings we can remove the tests for smsc,lan91c94 in gpmc.c. Signed-off-by: Tony Lindgren <tony@atomide.com>
* ARM: dts: Do not set pulls for I2C linesTony Lindgren2014-09-181-6/+6

* ARM: dts: omap: Remove WAKEUPENABLE mux options for UARTsTony Lindgren2014-09-181-2/+2
| | | | | | | | | | | | | This is no longer needed as the device specific wake-up event can now be specified with interrupts-extended property where the second interrupt is the pinctrl-single register, such as the UART3 RX pin. Note that twl4030_omap3.dtsi needs to set WAKEUPENABLE for off-idle to properly trigger the PMIC scripts. And GPIO pins still need to set WAKEUPENABLE for wake-up events.

* ARM: dts: omap3-overo: Fix UART wake-up eventsTony Lindgren2014-09-181-2/+3
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Compared to legacy booting, we don't have wake-up events enabled for device tree based booting. This means that if deeper idle states are enabled, the device won't wake up to UART events and seems like it has hung. Let's fix that by adding the wake-up interrupt. Note that we don't need to set the PIN_OFF_WAKEUPENABLE any longer, that's handled by the wake-up interrupt when the serial driver does request_irq on it. Tested with the following on omap3-overo-summit that has the ES2.1 omap: #!/bin/bash uarts=$(find /sys/class/tty/ttyO*/device/power/ -type d) for uart in $uarts; do echo 3000 > $uart/autosuspend_delay_ms done uarts=$(find /sys/class/tty/ttyO*/power/ -type d) for uart in $uarts; do echo enabled > $uart/wakeup echo auto > $uart/control done echo 1 > /sys/kernel/debug/pm_debug/enable_off_mode # grep -i uart /proc/interrupts 90: 1085 INTC 74 OMAP UART2 338: 5 pinctrl 366 OMAP UART2 # grep ^core_pwrdm /sys/kernel/debug/pm_debug/count core_pwrdm (ON),OFF:1654,RET:131,INA:39,ON:1825...

| * ARM: dts: OMAP5 / DRA7: switch over to interrupts-extended property for UARTNishanth Menon2014-09-092-16/+16
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | We've had deeper idle states working on omaps for few years now, but only in the legacy mode. When booted with device tree, the wake-up events did not have a chance to work until commit 3e6cee1786a1 ("pinctrl: single: Add support for wake-up interrupts") that recently got merged. In addition to that we also needed commit 79d9701559a9 ("of/irq: create interrupts-extended property") that's now also merged. Note that there's no longer need to specify the wake-up bit in the pinctrl settings, the request_irq on the wake-up pin takes care of that. Signed-off-by: Nishanth Menon <nm@ti.com>

This actually broke cpuidle-big_little initialization, as bl_idle_driver_init() performs a check using an hardcoded mask on cpu_id.

This patch resolves the issue in the following ways: - Replacing our uses of CLREX with a dummy STREX sequence instead (as we did for v6 CPUs). - Removing the clrex code from v7_exit_coherency_flush and derivatives, since this only exists as a minor performance improvement when non-cached exclusives are in use (Linux doesn't use these). Benchmarking on a variety of ARM cores revealed no measurable performance difference with this change applied, so the change is performed unconditionally and no new Kconfig entry is added.

Its status value will not be used. - Any other STREX in the kernel must be preceded by an LDREX, which will initialise the monitors consistently and will not depend on the earlier state of the monitors. Therefore we have no reason to care about the initial state of the exclusive monitors when a data abort is taken, and clearing the monitors prior to exception return (as we already do) is sufficient. This patch removes the redundant clearing of the exclusive monitors from the early abort handlers.

| * | | ARM: 8127/1: module: add support for R_ARM_TARGET1 relocationsAndrey Ryabinin2014-08-272-0/+2
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Kernel module build with GCOV profiling fails to load with the following error: $ insmod test_module.ko test_module: unknown relocation: 38 insmod: can't insert 'test_module.ko': invalid module format This happens because constructor pointers in the .init_array section have not supported R_ARM_TARGET1 relocation type. Documentation (ELF for the ARM Architecture) says: "The relocation must be processed either in the same way as R_ARM_REL32 or as R_ARM_ABS32: a virtual platform must specify which method is used." Since kernel expects to see absolute addresses in .init_array R_ARM_TARGET1 relocation type should be treated the same way as R_ARM_ABS32.

The delta is a largeish negative delta, due to revert of SMP support for Broadcom's STB SoC -- it was accidentally merged before some issues had been addressed, so they will make a new attempt for 3.18. I didn't see a need for a full revert of the whole platform due to this, we're keeping the rest enabled. The rest is mostly: - a handful of DT fixes for i.MX (Hummingboard/Cubox-i in particular) - some MTD/NAND fixes for OMAP - minor DT fixes for shmobile - warning fix for UP builds on vexpress/spc There's also a couple of patches that wires up hwmod on TI's DRA7 SoC so it can boot. Drivers and the rest had landed for 3.17, and it's small and isolated so it made sense to pick up now even if it's not a bugfix" * tag 'fixes-for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/arm/arm-soc: (23 commits) vexpress/spc: fix a build warning on array bounds ARM: DRA7: hwmod: Add dra74x and dra72x specific ocp interface lists ARM: DRA7: Add support for soc_is_dra74x() and soc_is_dra72x() variants MAINTAINERS: catch special Rockchip code locations ARM: dts: microsom-ar8035: MDIO pad must be set open drain ARM: dts: omap54xx-clocks: Fix the l3 and l4 clock rates ARM: brcmstb: revert SMP support ARM: OMAP2+: hwmod: Rearm wake-up interrupts for DT when MUSB is idled ARM: dts: Enable UART wake-up events for beagleboard ARM: dts: Remove twl6030 clk32g "regulator" ARM: OMAP2+: omap_device: remove warning that clk alias already exists ARM: OMAP: fix %d confusingly prefixed with 0x in format string ARM: dts: DRA7: fix interrupt-cells for GPIO mtd: nand: omap: Fix 1-bit Hamming code scheme, omap_calculate_ecc() ARM: dts: omap3430-sdp: Revert to using software ECC for NAND ARM: OMAP2+: GPMC: Support Software ECC scheme via DT mtd: nand: omap: Revert to using software ECC by default ARM: dts: hummingboard/cubox-i: change SPDIF output to be more descriptive ARM: dts: hummingboard/cubox-i: add USB OC pinctrl configuration ARM: shmobile: r8a7791: add missing 0x0100 for SDCKCR ...

Move USB OTG SS4 to dra74x only list since its unavailable in dra72x and is giving an abort during boot. The dra72x only list is empty for now and a placeholder for future hwmod additions which are specific to dra72x.
