2013-06-24ARM: mxs: don't select HAVE_PWMArnd Bergmann
The HAVE_PWM symbol is only for legacy platforms that provide the PWM API without using the generic framework. MXS actually uses that framework, and selecting the symbol anyway might cause build errors like drivers/built-in.o: In function `pwm_beeper_resume': :(.text+0x1f4fc0): undefined reference to `pwm_config' :(.text+0x1f4fc8): undefined reference to `pwm_enable' drivers/built-in.o: In function `pwm_beeper_suspend': :(.text+0x1f4ffc): undefined reference to `pwm_disable' when CONFIG_PWM is disabled.

2013-06-24ARM: 7773/1: PJ4B: Add support for errata 4742Gregory CLEMENT
This commit fixes the regression on Armada 370 (the kernal hang during boot) introduced by the commit: "ARM: 7691/1: mm: kill unused TLB_CAN_READ_FROM_L1_CACHE and use ALT_SMP instead". When coming out of either a Wait for Interrupt (WFI) or a Wait for Event (WFE) IDLE states, a specific timing sensitivity exists between the retiring WFI/WFE instructions and the newly issued subsequent instructions. This sensitivity can result in a CPU hang scenario. The workaround is to insert either a Data Synchronization Barrier (DSB) or Data Memory Barrier (DMB) command immediately after the WFI/WFE instruction. This commit was based on the work of Lior Amsalem, but heavily modified to apply the errata fix dynamically according to the processor type thanks to the suggestions of Russell King and Nicolas Pitre.

2013-06-24ARM: 7763/1: kernel: fix __cpu_logical_map default initializationLorenzo Pieralisi
The __cpu_logical_map array is statically initialized to 0, which is a valid MPIDR value. To prevent issues with the current implementation, this patch defines an MPIDR_INVALID value, and statically initializes the __cpu_logical_map[] array to it. Entries in the arm_dt_init_cpu_maps() tmp_map array used to stash DT reg properties while parsing DT are initialized with the MPIDR_INVALID value as well for consistency.

The DT parsing code needs updating otherwise it would check for cpu nodes properties in nodes that are not required to contain them, resulting in warnings that have no bearing on bindings defined in the dts source file.

2013-06-24ARM: 7760/1: cpu_fa526_do_idle: remove WFIJonas Jensen
As it was already suggested by Russell King and Arnd Bergmann: https://lkml.org/lkml/2013/5/16/133 moxart and gemini seem to be the only platforms using CPU_FA526, and instead of pointing arm_pm_idle to an empty function from platform code, it makes sense to remove WFI code from the processor specific idle function. Applies to arm-soc/for-next (and 3.10-rc1). Changes since v1: 1. remove WFI but make sure cpu_fa526_do_idle do not fall through to cpu_fa526_dcache_clean_area Note: moxart boots and prints to UART without this patch, but input is broken.

2013-06-23ARM: mvebu: fix length of ethernet registers in mv78260 dtsiEzequiel Garcia
The length of the registers area for the Marvell 370/XP Ethernet controller was incorrect in the .dtsi: 0x2500, while it should have been 0x4000. This problem wasn't noticed because there used to be a static mapping for all the MMIO register region set up by ->map_io(). The register length was fixed in all the other device tree files, except from the armada-xp-mv78260.dtsi, in the following commit: commit cf8088c5cac6ce20d914b9131533844b9291a054 Author: Thomas Petazzoni <thomas.petazzoni@free-electrons.com> Date: Tue May 21 12:33:27 2013 +0200 arm: mvebu: fix length of Ethernet registers area in .dtsi This commit fixes a kernel panic in mvneta_probe(), when the kernel tries to access the unmapped registers: [ 163.639092] mvneta d0070000.ethernet eth0: mac: 6e:3c:4f:87:17:2e [ 163.646962] mvneta d0074000.ethernet eth1: mac: 6a:04:4e:6f:f5:ef [ 163.654853] mvneta d0030000.ethernet eth2: mac: 2a:99:19:19:fc:4c [ 163.661258] Unable to handle kernel paging request at virtual address f011bcf0 [ 163.668523] pgd = c0004000 [ 163.671237] [f011bcf0] *pgd=2f006811, *pte=00000000, *ppte=00000000 [ 163.677565] Internal error: Oops: 807 [#1] SMP ARM [ 163.682370] CPU: 0 PID: 1 Comm: swapper/0 Not tainted 3.10.0-rc6-01850-gba0682e #11 [ 163.690046] task: ef04c000 ti: ef03e000 task.ti: ef03e000 [ 163.695467] PC is at mvneta_probe+0x34c/0xabc [...] Signed-off-by: Ezequiel Garcia <ezequiel.garcia@free-electrons.com> Acked-by: Thomas Petazzoni <thomas.petazzoni@free-electrons.com> Signed-off-by: Jason Cooper <jason@lakedaemon.net>
2013-06-23x86: Add NMI duration tracepointsDave Hansen
This patch has been invaluable in my adventures finding issues in the perf NMI handler. I'm as big a fan of printk() as anybody is, but using printk() in NMIs is deadly when they're happening frequently. Even hacking in trace_printk() ended up eating enough CPU to throw off some of the measurements I was making.

2013-06-23perf: Drop sample rate when sampling is too slowDave Hansen
This patch keeps track of how long perf's NMI handler is taking, and also calculates how many samples perf can take a second. If the sample length times the expected max number of samples exceeds a configurable threshold, it drops the sample rate. This way, we don't have a runaway sampling process eating up the CPU. This patch can tend to drop the sample rate down to level where perf doesn't work very well. *BUT* the alternative is that my system hangs because it spends all of its time handling NMIs. I'll take a busted performance tool over an entire system that's busted and undebuggable any day. BTW, my suspicion is that there's still an underlying bug here. Using the HPET instead of the TSC is definitely a contributing factor, but I suspect there are some other things going on. But, I can't go dig down on a bug like that with my machine hanging all the time.

2013-06-23x86: Warn when NMI handlers take large amounts of timeDave Hansen
I have a system which is causing all kinds of problems. It has 8 NUMA nodes, and lots of cores that can fight over cachelines. If things are not working _perfectly_, then NMIs can take longer than expected. If we get too many of them backed up to each other, we can easily end up in a situation where we are doing nothing *but* running NMIs. The biggest problem, though, is that this happens _silently_. You might be lucky to get an hrtimer warning, but most of the time system simply hangs. This patch should at least give us some warning before we fall off the cliff. the warnings look like this: nmi_handle: perf_event_nmi_handler() took: 26095071 ns The message is triggered whenever we notice the longest NMI we've seen to date. You can always view and reset this value via the debugfs interface if you like.

Although the internal register window size is 1 MiB, the previous ranges translation for the internal register space had a size of 0x4000000. This was done to allow the crypto and nand node to access the corresponding 'sram' and 'nand' decoding windows. In order to describe the hardware more accurately, we declare the real 1 MiB internal register space in the ranges, and add a translation entry for the nand node to access the 'nand' window.

Patches from Lee Jones: This gets rid of mop500_snowball_ethernet_clock_enable() which is no longer in use. It also straightens out a bug which ensures the SMSC911x's regulator is turned on at start-up when using Device Tree. Signed-off-by: Arnd Bergmann <arnd@arndb.de>
2013-06-21ARM: ux500: Remove mop500_snowball_ethernet_clock_enable()Lee Jones
mop500_snowball_ethernet_clock_enable() provided a means to enable a clock which was used for the SMSC911x Ethernet device on Snowball. It was merely a stand-in until the driver was common clk compliant. Now that it is, this can be removed for both DT and ATAGs booting.

2013-06-21ARM: ux500: Correct the EN_3v3 regulator's on/off GPIOLee Jones
When this node was added, the AB8500 GPIO driver was pretty broken. As a hack, we pretended that NOMADIK GPIO 26 was the correct on/off pin, as it was unused. It worked because AB8500 GPIO 26 was in an 'always on from boot' state. Now the AB8500 GPIO driver is working, the default state for all the pins is 'off'. Let's flip back over to use the correct GPIO which is _actually_ attached to the regulator. We're also taking the opportunity to straighten out some formatting misdemeanours, swapping spaces for tabs.

2013-06-21arm: add basic support for Rockchip RK3066a boardsHeiko Stuebner
This adds a generic devicetree board file and a dtsi for boards based on the RK3066a SoCs from Rockchip. Apart from the generic parts (gic, clocks, pinctrl) the only components currently supported are the timers, uarts and mmc ports (all DesignWare- based).

2013-06-21arm: add debug uarts for rockchip rk29xx and rk3xxx seriesHeiko Stuebner
Uarts on all recent Rockchip SoCs are Synopsis DesignWare 8250 types. Only their addresses vary very much. This patch adds the necessary definitions to use any of the uart ports for early debug purposes. Signed-off-by: Heiko Stuebner <heiko@sntech.de>
2013-06-21arm: Add basic clocks for Rockchip rk3066a SoCsHeiko Stuebner
This adds a basic clock setup for rk3066a SoCs. Only the gates are set up currently, as the mux and dividers should use the upcoming generic devicetree bindings. Clocks whose rates need to be known are supplied by fixed-rate "dummy"-clocks that provide the correct rate. This is uncritical insofar that the only bootloader currently in existence for Rockchip devices is the propietary Rockchip one that always setups the clocks in the necessary way.
