2011-02-18usb: otg: OMAP4430: Introducing suspend function for power managementHema HK
Introduced the suspend/resume function for the OMAP4430 internal PHY. This will be used by the twl6030-usb transceiver driver. Moved the clock enable/disable function calls and power on/off of the PHY code from power on/off functions to suspend/resume function. Pass the suspend function through board data for OMAP4430sdp and OMAP4panda. This will be used by the twl6030-usb transceiver driver.

2011-02-11ARM: 6657/1: hw_breakpoint: fix ptrace breakpoint advertising on unsupported ↵Will Deacon
arch The ptrace debug information register was advertising breakpoint and watchpoint resources for unsupported debug architectures. This meant that setting breakpoints on these architectures would appear to succeed, although they would never fire in reality. This patch fixes the breakpoint slot probing so that it returns 0 when running on an unsupported debug architecture.

Reading baseline CP14 registers, other than DBGDIDR, when the OS Lock is set leads to UNPREDICTABLE behaviour. This patch ensures that we clear the OS lock before accessing anything other than the DBGDIDR, thereby avoiding this behaviour.

2011-02-11ARM: 6659/1: Thumb-2: Make CONFIG_OABI_COMPAT depend on !CONFIG_THUMB2_KERNELDave Martin
rmk says: "You might as well make OABI_COMPAT depend on !THUMB2_KERNEL. OABI userland is useless without FPA support." nwfpe doesn't work with Thumb-2 anyway and will probably never get ported, so I can't argue with that. This patch implements the dependency change.

2011-02-11ARM: S5PV310: Add support System MMU on SMDKV310Thomas Abraham
The 's5pv310_device_sysmmu' is used on SMDKV310. But since it is not compiled now, there is a build error. To fix this compilation error, S5PV310_DEV_SYSMMU needs to be selected for SMDKV310 board.

2011-02-10ARM: 6654/1: perf/oprofile: fix off-by-one in stack checkRabin Vincent
Since tail is the previous fp - 1, we need to compare the new fp with tail + 1 to ensure that we don't end up passing in the same tail again, in order to avoid a potential infinite loop in the perf interrupt handler (which has been observed to occur). A similar fix seems to be needed in the OProfile code.

2011-02-10ARM: fixup SMP alternatives in modulesRussell King
With certain configurations, we inline the unlock functions in modules, which results in SMP alternatives being created in modules. We need to fix those up when loading a module to prevent undefined instruction faults. Signed-off-by: Russell King <rmk+kernel@arm.linux.org.uk>
2011-02-10ARM: make SWP emulation explicit on !CPU_USE_DOMAINSRussell King
SWP emulation requires that CPU domain support is disabled in order to work safely. Make that explicit in the kernel configuration to prevent illegal configurations being generated. Signed-off-by: Russell King <rmk+kernel@arm.linux.org.uk>
2011-02-09ARM: Avoid building unsafe kernels on OMAP2 and MX3Russell King
OMAP2 (armv6) and MX3 turn off support for the V6K instructions, which when they include support for SMP kernels means that the resulting kernel is unsafe on SMP and can result in corrupted filesystems as we end up using unsafe bitops. Re-enable the use of V6K instructions on such kernels, and let such kernels running on V6 CPUs eat undefined instruction faults which will be much safer than filesystem corruption. Next merge window we can fix this properly (as it requires a much bigger set of changes.) Acked-by: Tony Lindgren <tony@atomide.com> Signed-off-by: Russell King <rmk+kernel@arm.linux.org.uk>

2011-02-01OMAP3: Devkit8000: Change lcd power pinThomas Weber
This patch fixes a wrongly used lcd enable pin. The Devkit8000 uses twl4030_ledA configured as output gpio only for the lcd enable line. twl4030_gpio.1 is used through the generic gpio functions while ledA is used via low level twl4030 calls. This patch removes the low level calls and use the generic gpio functions for initialization and use of ledA. This patch also fixes a bug where the lcd would not power down when blanking. Further this patch fixes an indentation issue. The comment line uses eight whitespace and is replaced with a hard tab. gpio_request + gpio_direction_output are replaced with gpio_request_one. The return value of gpio_request_one is used to set the value of the gpio to -EINVAL when unsuccessful, so that gpio_is_valid can detect the unsuccessful request. But already successful requested gpios are not freed.
