Pull ARM SoC driver updates from Arnd Bergmann: "These are changes for drivers that are intimately tied to some SoC and for some reason could not get merged through the respective subsystem maintainer tree. Most of the new code is for the Keystone Navigator driver, which is new base support that is going to be needed for their hardware accelerated network driver and other units. Most of the commits are for moving old code around from at91 and omap for things that are done in device drivers nowadays. - at91: move reset, poweroff, memory and clocksource code into drivers directories - socfpga: add edac driver (through arm-soc, as requested by Boris) - omap: move omap-intc code to drivers/irqchip - sunxi: added an RTC driver for sun6i - omap: mailbox driver related changes - keystone: support for the "Navigator" component - versatile: new reboot, led and soc drivers" * tag 'drivers-for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/arm/arm-soc: (92 commits) bus: arm-ccn: Fix spurious warning message leds: add device tree bindings for register bit LEDs soc: add driver for the ARM RealView power: reset: driver for the Versatile syscon reboot leds: add a driver for syscon-based LEDs drivers/soc: ti: fix build break with modules MAINTAINERS: Add Keystone Multicore Navigator drivers entry soc: ti: add Keystone Navigator DMA support Documentation: dt: soc: add Keystone Navigator DMA bindings soc: ti: add Keystone Navigator QMSS driver Documentation: dt: soc: add Keystone Navigator QMSS bindings rtc: sunxi: Depend on platforms sun4i/sun7i that actually have the rtc rtc: sun6i: Add sun6i RTC driver irqchip: omap-intc: remove unnecessary comments irqchip: omap-intc: correct maximum number or MIR registers irqchip: omap-intc: enable TURBO idle mode irqchip: omap-intc: enable IP protection irqchip: omap-intc: remove unnecesary of_address_to_resource() call irqchip: omap-intc: comment style cleanup irqchip: omap-intc: minor improvement to omap_irq_pending() ...

sb_edac: Claim a different PCI device

2014-10-08T20:04:16Z

sb_edac controls a large number of different PCI functions. Rather than registering as a normal PCI driver for all of them, it registers for just one so that it gets probed and, at probe time, it looks for all the others. Coincidentally, the device it registers for also contains the SMBUS registers, so the PCI core will refuse to probe both sb_edac and a future iMC SMBUS driver. The drivers don't actually conflict, so just change sb_edac's device table to probe a different device. An alternative fix would be to merge the two drivers, but sb_edac will also refuse to load on non-ECC systems, whereas i2c_imc would still be useful without ECC. The only user-visible change should be that sb_edac appears to bind a different device. Signed-off-by: Andy Lutomirski Cc: Rui Wang Acked-by: Aristeu Rozanski Signed-off-by: Mauro Carvalho Chehab

Move Intel SNB device ids from sb_edac to pci_ids.h

2014-10-08T20:04:16Z

The i2c_imc driver will use two of them, and moving only part of the list seems messier. Signed-off-by: Andy Lutomirski Acked-by: Bjorn Helgaas Acked-by: Aristeu Rozanski Signed-off-by: Mauro Carvalho Chehab

sb_edac: avoid INTERNAL ERROR message in EDAC with unspecified channel

2014-10-08T20:04:16Z

Intel IA32 SDM Table 15-14 defines channel 0xf as 'not specified', but EDAC doesn't know about this and returns and INTERNAL ERROR when the channel is greater than NUM_CHANNELS: kernel: [ 1538.886456] CPU 0: Machine Check Exception: 0 Bank 1: 940000000000009f kernel: [ 1538.886669] TSC 2bc68b22e7e812 ADDR 46dae7000 MISC 0 PROCESSOR 0:306e4 TIME 1390414572 SOCKET 0 APIC 0 kernel: [ 1538.971948] EDAC MC1: INTERNAL ERROR: channel value is out of range (15 >= 4) kernel: [ 1538.972203] EDAC MC1: 0 CE memory read error on unknown memory (slot:0 page:0x46dae7 offset:0x0 grain:0 syndrome:0x0 - area:DRAM err_code:0000:009f socket:1 channel_mask:1 rank:0) This commit changes sb_edac to forward a channel of -1 to EDAC if the channel is not specified. edac_mc_handle_error() sets the channel to -1 internally after the error message anyway, so this commit should have no effect other than avoiding the INTERNAL ERROR message when the channel is not specified.

mpc85xx_edac: Make L2 interrupt shared too

2014-09-30T10:55:41Z
