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: NRussell King <rmk+kernel@arm.linux.org.uk>

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: NTony Lindgren <tony@atomide.com> Signed-off-by: NRussell King <rmk+kernel@arm.linux.org.uk>

This patch fixes bug introduced in revision: f8e9e984 omap1: DMA: move LCD related code from plat-omap to mach-omap1 The code introduced by this patch didn't consider any other CPUs but OMAP1510, which rendered OMAP310 -- which has the same LCD controller -- non-working. Use cpu_is_omap15xx() instead of cpu_is_omap1510() to squash this issue. Bug found on Palm Zire 71 hardware.

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.

Currently, on HS/EMU devices, MPU power state forced to on during PM init by the save secure RAM code. Rather than forcing the state of MPU powerdomain to on, simply read the current value and restore it after the ROM code has run. This only affects the !CPUidle case since when CPUidle is enabled, the MPU power state is dynamically changed by CPUidle. In the !CPUidle case, MPU power state is initialized once at init and never touched. Acked-by: NTero Kristo <tero.kristo@nokia.com> Signed-off-by: NKevin Hilman <khilman@ti.com>

The -rt patches change the console_semaphore to console_mutex. As a result, a quite large chunk of the patches changes all acquire/release_console_sem() to acquire/release_console_mutex() This commit makes things use more neutral function names which dont make implications about the underlying lock.

The EP93xx C and D GPIO ports are multiplexed with the Keypad Interface peripheral. At power-up they default into non-GPIO mode with the Key Matrix controller enabled so these ports are unusable for GPIO. Note that the Keypad Interface peripheral is only available in the EP9307, EP9312, and EP9315 processor variants. The keypad support will clear the DeviceConfig bits appropriately to enable the Keypad Interface when the driver is loaded. And, when the driver is unloaded it will set the bits to return the ports to GPIO mode. To make these ports available for GPIO after power-up on all EP93xx processor variants, set the KEYS and GONK bits in the DeviceConfig register. Similarly, the E, G, and H ports are multiplexed with the IDE Interface peripheral. At power-up these also default into non-GPIO mode. Note that the IDE peripheral is only available in the EP9312 and EP9315 processor variants. Since an IDE driver is not even available in mainline, set the EONIDE, GONIDE, and HONIDE bits in the DeviceConfig register so that these ports will be available for GPIO use after power-up.

Timers on Versatile Express mainboard are used as system clock/event sources. Driver assumes that they are clocked with 1MHz signal. Old V2M firmware apparently configured it by default, but on newer boards one can observe that "sleep 1" command takes over 30 seconds to finish, as the timers are fed with 32kHz instead... This patch performs required magic and also removes code clearing timer's control registers, as exactly the same operations are performed by the timer driver few jiffies later.

As no one seems to really know which configuration options tie up with which boards, I thought I'd do some investigation and try to work it out. After discussion with some folk in linaro, I think I have this nailed. The names are updated to use the name on the front of the appropriate board user guide for the various baseboards, which I've taken to be the official name for each board. I haven't significantly updated the descriptions for the tiles as that is even less clear - as far as I can see on ARMs website, there is no Cortex-A9 tile for Realview EB - only ARM11MPCore, ARM1156T2F-S, ARM1176TZF-S and Cortex-R4F.
