2012-04-22ARM: spear: remove most mach/*.h header contentsArnd Bergmann27-921/+423
The register and irq definitions in mach/*.h for spear3xx and spear6xx are now mostly obsolete, after the platforms have been converted to device tree based probing and the data is now part of the device tree files. The misc_regs.h contents are moved into clock.c because that is the only user, aside from the DMA_CHN_CFG that should eventually get handled differently. Some of the contents of mach/spear.h still remain, because they are used to set up the static map table, timer, uart and auxdata tables, but almost everything got removed. We might remove everything but the map table as the DT conversion completes, but that is not a priority. I've also made sure to make both copies of spear.h more or less identical so we can eventually combine them. The spear3?0.h files were only used by the spear3?0.c files, so I merged the contents in there and removed the bits that were unused. This is something that should still be looked at.

2012-04-22SPEAr: Add PL080 DMA support for 3xx and 6xxViresh Kumar17-4/+1104

2012-04-22ARM: SPEAr3xx: Add device-tree support to SPEAr3xx architectureViresh Kumar22-480/+1197
This patch adds a generic target for SPEAr3xx machines that can be configured via the device-tree. Currently the following devices are supported via the devicetree: - VIC interrupts - PL011 UART - PL061 GPIO - PL110 CLCD - SP805 WDT - Synopsys DW I2C - Synopsys DW ethernet - ST FSMC-NAND - ST SPEAR-SMI - ST SPEAR-KEYBOARD - ST SPEAR-RTC - ARASAN SDHCI-SPEAR - SPEAR-EHCI - SPEAR-OHCI Other peripheral devices will follow in later patches. This also removes IO_ADDRESS macro and creates 16 MB static mappings instead of 4K for individual peripherals. This is done to have efficient TLB lookup for any I/O windows that are located closely together. ioremap() on this range will return this mapping only instead of creating another.

Here is another fixes series for AT91 designed for 3.4-rc. We experienced some issues while compiling some drivers as modules: Joachim has corrected several of them. We may reduce this number of exported values by reworking some drivers, in the future. Some drivers are also modified here, I would like to keep them in the series as the modifications are really related with our recent move to irqdomains or simply related with compiler annotations. I keep dmaengine Kconfig modification in this "fixes" series.

2012-04-17ARM: OMAP1: DMTIMER: fix broken timer clock source selectionPaul Walmsley1-2/+2
DMTIMER source selection on OMAP1 is broken. omap1_dm_timer_set_src() tries to use __raw_{read,write}l() to read from and write to physical addresses, but those functions take virtual addresses. sparse caught this: arch/arm/mach-omap1/timer.c:50:13: warning: incorrect type in argument 1 (different base types) arch/arm/mach-omap1/timer.c:50:13: expected void const volatile [noderef] <asn:2>*<noident> arch/arm/mach-omap1/timer.c:50:13: got unsigned int arch/arm/mach-omap1/timer.c:52:9: warning: incorrect type in argument 1 (different base types) arch/arm/mach-omap1/timer.c:52:9: expected void const volatile [noderef] <asn:2>*<noident> arch/arm/mach-omap1/timer.c:52:9: got unsigned int Fix by using omap_{read,writel}(), just like the other users of the MOD_CONF_CTRL_1 register in the OMAP1 codebase. Of course, in the long term, removing omap_{read,write}l() is the appropriate thing to do; but this will take some work to do this cleanly. Looks like this was caused by 97933d6 (ARM: OMAP1: dmtimer: conversion to platform devices) that dangerously moved code and changed it in the same patch.

2012-04-17ARM: OMAP: serial: Fix the ocp smart idlemode handling bugSantosh Shilimkar1-1/+7
The current serial UART code, while fidling with ocp idlemode bits, forget about the smart idle wakeup bit even if it is supported by UART IP block. This will lead to missing the module wakeup on OMAP's where the smart idle wakeup is supported. This was the root cause of the console sluggishness issue, I have been observing on OMAP4 devices and also can be potential reason for some other UART wakeup issues.

2012-04-17ARM: OMAP2+: UART: Fix incorrect population of default uart padsGovindraj.R1-116/+0
Commit (7496ba3 ARM: OMAP2+: UART: Add default mux for all uarts) wrongly added muxing of default pads for all uarts. This causes breakage on multiple boards using uart pins for alternate functions. For example, on zoom3 random oopses can be seen with nfsroot as the smsc911x ethernet FIFO timings on GPMC bus are controlled by gpmc_wait2 and gpmc_wait3 pins. This means we can't mux these pads to uart4 functionality as commit 7496ba3 was doing. Not all boards tend to use all uarts and most of unused uart pins are muxed for other purpose. This commit breaks the modules which where trying to use unused uart pins on their boards. So remove the default pad muxing. Note that this is not a complete fix, as we now rely on bootloader set muxing for the uart wake-up events. Further patching is needed to enable wake-up events for uarts that are already muxed to uart mode.

2012-04-16ARM: ux500: update defconfigLinus Walleij1-5/+4
Some new drivers and changed Kconfig dependencies for the v3.4 kernel affecting the U8500 defconfig: - The SOC config options are now brought in by default - No need to explicitly select misc devices anymore - I2C is selected by default - We now have support for charging from the AB8500 so compile in this - The regulator framework needs to be explictly selected Signed-off-by: Linus Walleij <linus.walleij@linaro.org>
2012-04-16ARM: ux500: Fix unmet direct dependencyLee Jones1-0/+1
A recent change to a Kconfig configuration saw MACH_U8500 remove TPS6105X selection. In doing so Kconfig stopped selecting REGULATORS, which is still required. This patch sees UX500_SOC_DB8500 explicitly select it instead. Signed-off-by: Lee Jones <lee.jones@linaro.org> Signed-off-by: Linus Walleij <linus.walleij@linaro.org>

Pull ARM fixes from Russell King: "Nothing too disasterous, the biggest thing being the removal of the regulator support for vcore in the AMBA driver; only one SoC was using this and it got broken during the last merge window, which then started causing problems for other people. Mutual agreement was reached for it to be removed." * 'fixes' of git://git.linaro.org/people/rmk/linux-arm: ARM: 7386/1: jump_label: fixup for rename to static_key ARM: 7384/1: ThumbEE: Disable userspace TEEHBR access for !CONFIG_ARM_THUMBEE ARM: 7382/1: mm: truncate memory banks to fit in 4GB space for classic MMU ARM: 7359/2: smp_twd: Only wait for reprogramming on active cpus ARM: 7383/1: nommu: populate vectors page from paging_init ARM: 7381/1: nommu: fix typo in mm/Kconfig ARM: 7380/1: DT: do not add a zero-sized memory property ARM: 7379/1: DT: fix atags_to_fdt() second call site ARM: 7366/3: amba: Remove AMBA level regulator support ARM: 7377/1: vic: re-read status register before dispatching each IRQ handler ARM: 7368/1: fault.c: correct how the tsk->[maj|min]_flt gets incremented

2012-04-15ARM: 7384/1: ThumbEE: Disable userspace TEEHBR access for !CONFIG_ARM_THUMBEEJonathan Austin1-0/+12
Currently when ThumbEE is not enabled (!CONFIG_ARM_THUMBEE) the ThumbEE register states are not saved/restored at context switch. The default state of the ThumbEE Ctrl register (TEECR) allows userspace accesses to the ThumbEE Base Handler register (TEEHBR). This can cause unexpected behaviour when people use ThumbEE on !CONFIG_ARM_THUMBEE kernels, as well as allowing covert communication - eg between userspace tasks running inside chroot jails. This patch sets up TEECR in order to prevent user-space access to TEEHBR when !CONFIG_ARM_THUMBEE. In this case, tasks are sent SIGILL if they try to access TEEHBR.

2012-04-15ARM: 7382/1: mm: truncate memory banks to fit in 4GB space for classic MMUWill Deacon1-1/+15
If a bank of memory spanning the 4GB boundary is added on a !CONFIG_LPAE kernel then we will hang early during boot since the memory bank will have wrapped around to zero. This patch truncates memory banks for !LPAE configurations when the end address is not representable in 32 bits.

2012-04-15ARM: 7359/2: smp_twd: Only wait for reprogramming on active cpusLinus Walleij1-1/+5
During booting of cpu1, there is a short window where cpu1 is online, but not active where cpu1 is occupied by waiting to become active. If cpu0 then decides to schedule something on cpu1 and wait for it to complete, before cpu0 has set cpu1 active, we have a deadlock. Typically it's this CPU frequency transition that happens at this time, so let's just not wait for it to happen, it will happen whenever the CPU eventually comes online instead.
