Current implementation of LCD and backlight power control functions is not complete, as result PDA consumes power in suspend.

This patch implements h1940-specific set_power callback for s3cmci driver, so card power can be disabled when card is not inserted or before suspend.

This patch adds gpiolib support for h1940 latch. With this patch it's possible to use leds-gpio and uda1380 drivers (they require gpiolib support for appropriate pins).

Thomas Pollet noticed that the remap_file_pages() system call in fremap.c has a potential overflow in the first part of the if statement below, which could cause it to process bogus input parameters. Specifically the pgoff + size parameters could be wrap thereby preventing the system call from failing when it should.

Add logic to prevent two I/O requests being merged if only one of them is a discard. Ditto secure discard. Without this fix, it is possible for write requests to transform into discard requests. For example: Submit bio 1 to discard 8 sectors from sector n Submit bio 2 to write 8 sectors from sector n + 16 Submit bio 3 to write 8 sectors from sector n + 8 Bio 1 becomes request 1. Bio 2 becomes request 2. Bio 3 is merged with request 2, and then subsequently request 2 is merged with request 1 resulting in just one I/O request which discards all 24 sectors.

This "bpt_code" instruction was killed off in our development line a while ago (the actual definition of bpt_code that is used is in kernel/traps.c) but I didn't push it for 2.6.36 because it seemed harmless and I didn't want to try to push more than absolutely necessary. However, we recently fixed a bug in our gcc that had been causing "-gdwarf2" not to be passed to the assembler, and passing this flag causes an erroneous assembler failure in the presence of code in a data section, sometimes. While we'd like to track down the bug in the assembler, we'd also like to make sure 2.6.36 builds with the current toolchain, so I'm removing this dead code as well.

Thomas Pollet points out that the 'end' variable is broken. It was computed based on start/size before they were page-aligned, and as such doesn't actually match any of the other actions we take. The overflow test on end was also redundant, since we had already tested it with the properly aligned version. So just get rid of it entirely. The one remaining use for that broken variable can just use 'start+size' like all the other cases already did.

Just like pkgtemp registers another core of the same package when one gets removed, coretemp should register another hyperthread (if available) in that situation. As pointed out in the patch fixing the respective code in pkgtemp, the list protectng mutex must be dropped before calling coretemp_device_add(), and due to the restructured loop (including an explicit return) the "safe" variant of the list iterator isn't needed anymore.

pkgtemp_device_remove(), holding the list protecting mutex, calls pkgtemp_device_add(), which itself wants to acquire the same mutex. Holding the mutex over the entire loop body in pkgtemp_device_remove() isn't really necessary, as long as the loop gets exited after processing the matched CPU. Once exiting the loop after removing an eventual match, there's no need for using the "safe" list iterator anymore.

In commit 0dca94ba the call to platform_driver_unregister() was made conditional upon !HOTPLUG_CPU, but the return value from coretemp_init() was left to indicate an error. This isn't correct, as the negative return value indicates to the module loader that initialization failed, which isn't intended here and results in dangling pointers.

This patch fixes the issue which was observed while transfering a large file ( > 20MB) over USB (OMAP MUSB controller acts as USB host) to an attached USB thumb drive. It was found that CDB field of CBW packet was set to 0x0. This was due to missing a barrier before DMA engine starts transfer. This buffer is allocated using dma_alloc_coherent which gives non-cacheble but bufferable memory and hence needed a write memory barrier to flush the write buffer.

This patch fixes one bugs of OUT transfer in double buffer case: -the current code only enable autoclear for dma mode 1, and not for dma mode 0 Without this patch, test #5 of usbtest can't be passed if we configure musb as g_zero and use fifo mode 3 to enable double buffer mode. With this patch and the following patch(fix dma length), on my beagle B5, test#5(queued bulk out) may go beyond 18Mbyte/s(seems dma mode 0 is quicker in double buffer case) if musb is configured as g_zero and fifo mode 3 is taken, follows the test command: #./testusb -D DEV_NAME -c 1024 -t 5 -s 32768 -g 8 [1] Also I have tested this patch can't make g_ether broken.

This patch fixes one infinite hang of bulk IN transfer in double buffer case, the hang can be observed easily by test #6 of usbtest if musb is configured as g_zero and fifo mode 3 is taken to enable double fifo. In fact, the patch only removes the check for non-empty fifo before loading data from new request into fifo since the check is not correct: -in double buffer case, fifo may accommodate more than one packet, even though it has contained one packet already and is non-empty -since last DMA is completed before calling musb_g_tx, it is sure that fifo may accommodate at least one packet Without applying the patch, new requst enqueued from .complte may not have a chance to be loaded into fifo, then will never be completed and cause infinite hangs. With the patch, on my beagle B5, test#6(queued bulk in) can be passed and test result may go beyond 33Mbyte/s if musb is configured as g_zero and fifo mode 3 is taken, follows the test command: #testusb -D DEV_NAME -c 1024 -t 6 -s 32768 -g 8 [1] [1], -source of testusb : tools/usb/testusb.c under linux kernel; Signed-off-by: NMing Lei <tom.leiming@gmail.com> Acked-by: NAnand Gadiyar <gadiyar@ti.com> Cc: David Brownell <dbrownell@users.sourceforge.net> Cc: Anand Gadiyar <gadiyar@ti.com> Cc: Mike Frysinger <vapier@gentoo.org> Cc: Sergei Shtylyov <sshtylyov@ru.mvista.com> Signed-off-by: NFelipe Balbi <balbi@ti.com> Signed-off-by: NGreg Kroah-Hartman <gregkh@suse.de>
