2015-02-26ARM: DRA7: hwmod_data: Fix hwmod data for pcieKishon Vijay Abraham I
Fixed hwmod data for pcie by having the correct module mode offset. Previously this module mode offset was part of pcie PHY which was wrong. Now this module mode offset was moved to pcie hwmod and removed the hwmod data for pcie phy. While at that renamed pcie_hwmod to pciess_hwmod in order to match with the name given in TRM. This helps to get rid of the following warning "omap_hwmod: pcie1: _wait_target_disable failed" [Grygorii.Strashko@linaro.org: Found the issue that actually caused "omap_hwmod: pcie1: _wait_target_disable failed"] Signed-off-by: Grygorii Strashko <Grygorii.Strashko@linaro.org> Signed-off-by: Kishon Vijay Abraham I <kishon@ti.com> Signed-off-by: Paul Walmsley <paul@pwsan.com>
2015-02-26ARM: omap2+: omap_hwmod: Set unique lock_class_key per hwmodPeter Ujfalusi
Add struct lock_class_key to omap_hwmod struct and use it to set unique lockdep class per hwmod. This will ensure that lockdep will know that each omap_hwmod->_lock should be treated as separate class and will not give false warning about deadlock or other issues due to nested use of hwmods. DRA7x's ATL hwmod is one example for this since McASP can select ATL clock as functional clock, which will trigger nested oh->_lock usage. This will trigger false warning from lockdep validator as it is dealing with classes and for it all hwmod clocks are the same class.

In commit 87517d26d888 ("ARM: dts: dra7-evm: Add extcon nodes for USB") we enabled Extcon USB gpio to tackle the USB ID pin and get peripheral mode to work. But the extcon-gpio-usb driver [1] didn't make it into v4.0 and this makes the USB driver defer probe indefinitely breaking USB Host functionality. As a temporary fix we remove the extcon handle from the USB controller and add it back when the extcon driver merges in v4.1.

Offset for smc91x must be zero otherwise smc91x linux kernel driver does not detect smc91x ethernet hardware in qemu N900 machine. The 0x300 offset was used to supress a warning the smsc911x driver produces about non-standard offset as 0x300 seems to be the EEPROM default. As only three address lines are connected both 0 and 0x300 will work just fine with 0 being correct. The warning about the non-standard offset can be fixed by writing to EEPROM as that's needed in any case to set the MAC address.

2015-02-24ARM: dts: Fix USB dts configuration for dm816xTony Lindgren
Commit 7800064ba507 ("ARM: dts: Add basic dm816x device tree configuration") added basic devices for dm816x, but I was not able to test the USB completely because of an unconfigured USB phy, and I only tested it to make sure the Mentor chips are detected and clocked without a phy. After testing the USB with actual devices I noticed a few issues that should be fixed to avoid confusion: - The USB id pin on dm8168-evm is hardwired and can be changed only by software. As there are two USB-A type connectors, let's start both in host mode instead of otg. - The Mentor core is configured in such a way on dm8168-evm that it's not capable of multipoint at least on revision c board that I have. - We need ranges for the syscon to properly set up the phy as children of the SCM syscon area. - Let's not disable the second interface, the board specific dts files can do that if really needed. Most boards should just keep it enabled to ensure the device is idled properly. Note that also a phy and several musb fixes are still needed to make the USB to work properly in addition to this fix.

2015-02-23ARM: pxa: fix pxa interrupts handling in DTRobert Jarzmik
The commit "ARM: pxa: arbitrarily set first interrupt number" changed the first pxa interrupt to 16. As a consequence, device-tree builds got broken, because : - pxa_mask_irq() and pxa_unmask_irq() are using IRQ_BIT() - IRQ_BIT(x) calculates the interrupts as : x - PXA_IRQ(0) Before the commit, the first interrupt shift, PXA_IRQ(0) was 0, therefore IRQ_BIT(x) was x. After the change, it is necessary that the same shift of 16 is applied between the virtual interrupt number and the hardware irq number. This situation comes from the common irq_chip shared between legacy platform builds and device-tree builds. Fix the broken interrupts in DT case by adding this shift in the DT case too. As a consequence of the IRQ_BIT() is removed alltogether from interrupts handling, even in the platform data types of platforms : - a legacy irq domain is used - the irq_chip handles hardware interrupts - the virtual to hardware interrupt conversion is fully handled by irq domain mechanics Signed-off-by: Robert Jarzmik <robert.jarzmik@free.fr>

2015-02-20ARM: 8305/1: DMA: Fix kzalloc flags in __iommu_alloc_buffer()Alexandre Courbot
There doesn't seem to be any valid reason to allocate the pages array with the same flags as the buffer itself. Doing so can eventually lead to the following safeguard in mm/slab.c's cache_grow() to be hit: if (unlikely(flags & GFP_SLAB_BUG_MASK)) { pr_emerg("gfp: %un", flags & GFP_SLAB_BUG_MASK); BUG(); } This happens when buffers are allocated with __GFP_DMA32 or __GFP_HIGHMEM. Fix this by allocating the pages array with GFP_KERNEL to follow what is done elsewhere in this file. Using GFP_KERNEL in __iommu_alloc_buffer() is safe because atomic allocations are handled by __iommu_alloc_atomic().

As it calls a function that is only provided sometimes, this can result in a link error: arch/arm/mach-mvebu/built-in.o: In function `mvebu_armada375_smp_wa_init': :(.text+0x228): undefined reference to `mvebu_setup_boot_addr_wa' To solve this, we can just change the existing #ifdef around the function to also check for Armada375 SMP platforms.

2015-02-18ARM: sti: always enable RESET_CONTROLLERArnd Bergmann
A lot of the sti device drivers require reset controller support, but do not all have individual 'depends on RESET_CONTROLLER' statements. Using 'select' here once avoids a lot of build errors resulting from this.

If CONFIG_PM_SLEEP is disabled, we get a build error for rockchips: arch/arm/mach-rockchip/built-in.o: In function `rockchip_dt_init': :(.init.text+0x1c): undefined reference to `rockchip_suspend_init' This adds an inline alternative for that case.

2015-02-18ARM: ixp4xx: fix {in,out}s{bwl} data typesArnd Bergmann
Most platforms use void pointer arguments in these functions, but ixp4xx does not, which triggers lots of warnings in device drivers like: net/ethernet/8390/ne2k-pci.c: In function 'ne2k_pci_get_8390_hdr': net/ethernet/8390/ne2k-pci.c:503:3: warning: passing argument 2 of 'insw' from incompatible pointer type insw(NE_BASE + NE_DATAPORT, hdr, sizeof(struct e8390_pkt_hdr)>>1); ^ In file included from include/asm/io.h:214:0, from /git/arm-soc/include/linux/io.h:22, from /git/arm-soc/include/linux/pci.h:31, from net/ethernet/8390/ne2k-pci.c:48: mach-ixp4xx/include/mach/io.h:316:91: note: expected 'u16 *' but argument is of type 'struct e8390_pkt_hdr *' static inline void insw(u32 io_addr, u16 *vaddr, u32 count) Fixing the drivers seems hopeless, so this changes the ixp4xx code to do the same as the others to avoid the warnings.

2015-02-18ARM: prima2: do not select SMP_ON_UPArnd Bergmann
The new Atlas7 platform implicitly selects 'CONFIG_SMP_ON_UP', which leads to problems if we enable building the platform without MMU, as that combination is not allowed and causes a link error: arch/arm/kernel/built-in.o: In function `c_show': :(.text+0x1872): undefined reference to `smp_on_up' :(.text+0x1876): undefined reference to `smp_on_up' arch/arm/kernel/built-in.o: In function `arch_irq_work_raise': :(.text+0x3d48): undefined reference to `smp_on_up' :(.text+0x3d4c): undefined reference to `smp_on_up' arch/arm/kernel/built-in.o: In function `smp_setup_processor_id': :(.init.text+0x180): undefined reference to `smp_on_up' This removes the 'select' statement.

2015-02-18ARM: at91: fix pm declarationsArnd Bergmann
In a recent rearrangement of the at91 pm initialization code, a broken set of declarations was added for the !CONFIG_PM-case, leading to this link error: arch/arm/mach-at91/board-dt-sama5.o: In function `at91_rm9200_pm_init': arch/arm/mach-at91/generic.h:40: multiple definition of `at91_rm9200_pm_init' arch/arm/mach-at91/setup.o:arch/arm/mach-at91/generic.h:40: first defined here arch/arm/mach-at91/board-dt-sama5.o: In function `at91_sam9260_pm_init': arch/arm/mach-at91/generic.h:41: multiple definition of `at91_sam9260_pm_init' arch/arm/mach-at91/setup.o:arch/arm/mach-at91/generic.h:41: first defined here arch/arm/mach-at91/board-dt-sama5.o: In function `at91_sam9g45_pm_init': arch/arm/mach-at91/generic.h:42: multiple definition of `at91_sam9g45_pm_init' arch/arm/mach-at91/setup.o:arch/arm/mach-at91/generic.h:42: first defined here This adds the missing 'static inline' to the declarations to avoid creating a copy of the functions in each file that includes the header.

2015-02-18ARM: davinci: multi-soc kernels require AUTO_ZRELADDRArnd Bergmann
The davinci DA8xx and DMx families have incompatible zreladdr settings, and attempting to build a kernel with both enabled results in an error unless AUTO_ZRELADDR is set: multiple zreladdrs: 0xc0008000 0x80008000 This needs CONFIG_AUTO_ZRELADDR to be set This patch changes Kconfig to make the two families mutually exclusive when this is unset.

2015-02-18ARM: davinci: davinci_cfg_reg cannot be initArnd Bergmann
davinci_cfg_reg gets called from a lot of locations that might get called after the init section has been discarded, so the function itself must not be marked __init either. The kernel build currently warns about this with lots of messages like: WARNING: vmlinux.o(.text.unlikely+0x24c): Section mismatch in reference from the function dm365evm_mmc_configure() to the function .init.text:davinci_cfg_reg() The function dm365evm_mmc_configure() references the function __init davinci_cfg_reg(). This is often because dm365evm_mmc_configure lacks a __init annotation or the annotation of davinci_cfg_reg is wrong. This removes the extraneous __init_or_module annotation.
