2011-10-01ARM: add io{read,write}{16,32}be functionsArnd Bergmann
These functions are used in some PCI drivers with big-endian MMIO space, and they are trivial to add here. Signed-off-by: Arnd Bergmann <arnd@arndb.de>
2011-10-01ARM: limit CONFIG_HAVE_IDE to platforms that doArnd Bergmann
Support for IDE drivers should not be automatic, since most platforms cannot actually support any IDE low-level drivers. This partly reverts 2064c946e "ARM: always select HAVE_IDE" to set this symbol only when either a PC-style bus (PCI, ISA, PCMCIA) is enabled or a platform is used that is known to have an existing driver in drivers/ide. New platforms should not need this option and just use CONFIG_ATA with drivers/ata/. Signed-off-by: Arnd Bergmann <arnd@arndb.de>
2011-10-01ARM: pm: let platforms select cpu_suspend supportArnd Bergmann
Support for the cpu_suspend functions is only built-in when CONFIG_PM_SLEEP is enabled, but omap3/4, exynos4 and pxa always call cpu_suspend when CONFIG_PM is enabled. Signed-off-by: Arnd Bergmann <arnd@arndb.de>
2011-10-01ARM: vfp: use -mfloat-abi=soft to build vfpArnd Bergmann
Distros are starting to ship with toolchains defaulting to hardfloat. Using such a compiler to build the kernel fails in the VFP directory with arch/arm/vfp/entry.S:1:0: sorry, unimplemented: -mfloat-abi=hard and VFP Adding -mfloat-abi=soft to the gcc command line fixes this.

2011-10-01ARM: allow building alignment.c without PROC_FSArnd Bergmann
The two functions cpu_is_v6_unaligned and safe_usermode are only defined when CONFIG_PROC_FS is enabled, but are used outside of the #ifdef. Signed-off-by: Arnd Bergmann <arnd@arndb.de> Cc: Dave Martin <dave.martin@linaro.org>
2011-10-01ARM: always use ARM_UNWIND for thumb2 kernelsArnd Bergmann
Thumb2 kernels cannot be built with frame pointers, but can use the ARM_UNWIND feature for unwinding instead. This makes sure that all features that rely on unwinding includeing CONFIG_LATENCYTOP and FAULT_INJECTION_STACKTRACE_FILTER do not enable frame pointers when the unwinder is already selected, and we always build with the unwinder when we want a thumb2 kernel, to make sure we do not get the frame pointers instead. A different option would be to redefine the CONFIG_FRAME_POINTERS option on ARM to mean builing with either frame pointers or the unwinder, and then select which one to use based on the CPU architecture or another user option. That would still allow building thumb2 kernels without the unwinder but would also be more confusing. Signed-off-by: Arnd Bergmann <arnd@arndb.de>
2011-10-01ARM: SMP depends on MMUArnd Bergmann
The SMP implementation on ARM heavily depends on MMU-only code. As long as nobody is interested in fixing this, let's disable the SMP option when building for nommu. Signed-off-by: Arnd Bergmann <arnd@arndb.de>
2011-10-01ARM: export rtc_lock for nvram driverArnd Bergmann
The rtc_lock is used by both the nvram and rtc drivers, so we need to export it if at least one of the two is built, not just for the rtc driver. Signed-off-by: Arnd Bergmann <arnd@arndb.de>
2011-10-01ARM: 7113/1: mm: Align bank start to MAX_ORDER_NR_PAGESLinus Walleij
The VM subsystem assumes that there are valid memmap entries from the bank start aligned to MAX_ORDER_NR_PAGES. On the Ux500 we have a lot of mem=N arguments on the commandline triggering this bug several times over and causing kernel oops messages.

2011-10-01ARM: omap: use __devexit_p in dmtimer driverArnd Bergmann

Current code calls omap4430_phy_init() twice in usb_musb_init(). Calling omap4430_phy_init() once is enough.

2011-09-30ARM: OMAP4: MMC: fix power and audio issue, decouple USBC1 from MMC1Bryan Buckley
Remove OMAP4_USBC1_ICUSB_PWRDNZ_MASK during enable/disable PWRDNZ mode for MMC1_PBIAS and associated extended-drain MMC1 I/O cell. This is in accordance with the control module programming guide. This fixes a bug where if trying to use gpio_98 or gpio_99 and MMC1 at the same time the GPIO signal will be affected by a changing SDMMC1_VDDS. Software must keep MMC1_PBIAS cell and MMC1_IO cell PWRDNZ signals low whenever SDMMC1_VDDS ramps up/down or changes for cell protection purposes. MMC1 is based on SDMMC1_VDDS whereas USBC1 is based on SIM_VDDS therefore they can operate independently.

2011-09-30OMAP: stalker: Remove LCD device from board fileTomi Valkeinen
OMAP3 Stalker board has definitions for LCD, but uses the generic driver without any information what kind of LCD it has. The board should use a particular panel type from panel-generic-dpi driver, not the generic one. As I haven't gotten response the signer-off of stalker board about the issue, this patch removes the LCD support from the board file. This will allow us to clean up the panel-generic-dpi driver and make it support only fixed size panels.

Implement dsi_mux_pads for OMAP4. On enable the function enables the DSI pins and disables pull down. On disable the function disables the pins and enables pull down.

2011-09-28arm/imx: change mxc_init_l2x0() to an imx31/35 specific callShawn Guo
The mxc_init_l2x0() should really be an imx31/35 specific call. The patch removes early_initcall from mxc_init_l2x0() and get imx31 and imx35 soc specific function calls mxc_init_l2x0(), so that it's not necessarily to be called for all imx socs when we build single image for multiple imx socs. Thus the function can be renamed to imx3_init_l2x0() and put into mm-imx3.c. It also changes the return type from integer to void. From what I see, the integer was picked just to satisfy early_initcall prototype. With the patch 'ARM: l2x0: add empty l2x0_of_init' applied, the code compiles even without CONFIG_CACHE_L2X0 enabled.
