2009-01-07parport: ieee1284: use del_timer_sync() in parport_wait_event()Michael Buesch1-1/+1
Use del_timer_sync() instead of del_timer() to make sure the timer won't be running when we return from parport_wait_event(), because this would crash due to destruction of timer_list. This is untested and just based on a code review. Just think about the following sequence of events: - add_timer() - down_interruptible() is interrupted by a signal. - we enter the timer callback handler on another CPU. - del_timer(), but the timer callback is still running. - eturn from parport_wait_even, which destroys the automatic variable "timer" while the callback is running on another CPU.

2009-01-07edac: fix mpc85xx and add mpc8536 mpc8560Kumar Gala1-42/+32
All other compatibles that are uniquely identifying the processor use a prefix of the form fsl,mpc85...'. We add support for it so we can deprecate the older 'fsl,85...' that was improperly used here. Additionally added mpc8536 & mpc8560 to the compatible lists. This patch is based on Nate's 8572 patch.

This patch is part of a larger patch series which will remove the "char bus_id[20]" name string from struct device. The device name is managed in the kobject anyway, and without any size limitation, and just needlessly copied into "struct device".

2009-01-07random: don't try to look at entropy_count outside the lockMatt Mackall1-3/+2
As a non-atomic value, it's only safe to look at entropy_count when the pool lock is held, so we move the BUG_ON inside the lock for correctness. Also remove the spurious comment. It's ok for entropy_count to temporarily exceed POOLBITS so long as it's left in a consistent state when the lock is released. This is a more correct, simple, and idiomatic fix for the bug in 8b76f46a2db. I've left the reorderings introduced by that patch in place as they're harmless, even though they don't properly deal with potential atomicity issues.

2009-01-07fbdev/logo: check compatibility of main and extra logosGeert Uytterhoeven1-0/+4
The code to draw penguin logos always uses some properties of the main logo. This is incorrect if additional logos (CONFIG_FB_LOGO_EXTRA=y) have different types than the main logo, which causes corrupted logo images. http://bugzilla.kernel.org/show_bug.cgi?id=12181 Hence skip additional logos that are not compatible with the main logo. Technically, it's possible to draw multiple logos of different types on truecolor displays, but this would complicate the (already quite complicated) logo drawing code even more.

Provide a static debounce configuration mechanism for twl4030 GPIOs, replacing the previous dynamic one. The single user of that mechanism was for MMC card detect debouncing. Boards can provide a bitmask saying which GPIOs to debounce (30 msec). It's always enabled for pins with the MMC card-detect/VMMCx link active, so most boards won't need to set the debounce mask. This is a net code shrink, including runtime footprint.

2009-01-07rtc: bunch of drivers: fix 'no irq' case handingAnton Vorontsov9-40/+40
This patch fixes a bunch of irq checking misuses. Most drivers were getting irq via platform_get_irq(), which returns -ENXIO or r->start. rtc-cmos.c is special. It is using PNP and platform bindings. Hopefully nobody is using PNP IRQ 0 for RTC. So the changes should be safe. rtc-sh.c is using platform_get_irq, but was storing a result into an unsigned type, then was checking for < 0. This is fixed now.

2009-01-07drivers/spi: move a dereference below a NULL testJulia Lawall1-1/+2
In each case, if the NULL test is necessary, then the dereference should be moved below the NULL test. The semantic patch that makes this change is as follows: (http://www.emn.fr/x-info/coccinelle/) // <smpl> @@ type T; expression E; identifier i,fld; statement S; @@ - T i = E->fld; + T i; ... when != E when != i if (E == NULL) S + i = E->fld; // </smpl> Signed-off-by: Julia Lawall <julia@diku.dk> Acked-by: David Brownell <dbrownell@users.sourceforge.net> Signed-off-by: Andrew Morton <akpm@linux-foundation.org> Signed-off-by: Linus Torvalds <torvalds@linux-foundation.org>

2009-01-07spi: atmel_spi update chipselect handlingHaavard Skinnemoen1-26/+67
This solves several issues: * It fixes the wrong idle clock polarity issue in a cleaner and less expensive way. * It handles the AT32AP7000 errata "SPI Chip Select 0 BITS field overrides other Chip Selects". Other chips, e.g. AT91SAM9261, have similar issues. Currently, the AT91RM9200 code path is left alone. But it might be interesting to try the same technique on RM9200 using a different CSR register.

2009-01-07atmel_spi: clean up SPIv1 quirk handlingHaavard Skinnemoen1-18/+22
Currently, we have a flag called "new_1" which is basically equivalent to cpu_is_at91rm9200(). The latter is also called directly a few places. Clean up this mess by introducing a atmel_spi_v2() function for determining the controller version, and move all version dependent code over to use it. This allows us to remove the new_1 flag.

2009-01-07spi_gpio driverDavid Brownell3-1/+378
Generalize the old at91rm9200 "bootstrap" bitbanging SPI master driver as "spi_gpio", so it works with arbitrary GPIOs and can be configured through platform_data. Such SPI masters support: - any number of bus instances (bus_num is the platform_device.id) - any number of chipselects (one GPIO per spi_device) - all four SPI_MODE values, and SPI_CS_HIGH - i/o word sizes from 1 to 32 bits; - devices configured as with any other spi_master controller When configured using platform_data, this provides relatively low clock rates. On platforms that support inlined GPIO calls, significantly improved transfer speeds are also possible with a semi-custom driver. (It's still painful when accessing flash memory, but less so.) Sanity checked by using this version to replace both native controllers on a board with six different SPI slaves, relying on three different SPI_MODE_* values and both SPI_CS_HIGH settings for correct operation.
