| * mtd: nand: omap: fix race condition in omap_wait()Ivan Djelic2012-05-141-1/+3
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | If a context switch occurs in function omap_wait() just before the while loop is entered, then upon return from context switch the timeout may already have elapsed: in that case, status is never read from NAND device, and omap_wait() returns an error. This failure has been experimentally observed during stress tests. This patch ensures a NAND status read is always performed before returning, as in the generic nand_wait() function.

| * mtd: print out the page size and oob size after parsing out the nandHuang Shijie2012-05-141-4/+5
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Some not-supported nand chips may pass the current parsing code, and get the wrong page size and oob size. Sometimes, it's hard to notice that you get the wrong values, because there is no warning or error. So it's useful to print out the page size and oob size in the end of the parsing function. We can check these values with the datasheet of the nand chip as soon as possible.

| * | toshiba_acpi: Add support for transflective LCDAkio Idehara2012-05-311-4/+57
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Some Toshiba laptops have the transflective LCD and toshset can control its backlight state. I brought this feature to the mainline. To support transflective LCD, it's implemented by adding an extra level to the backlight and having 0 change to transflective mode. It was tested on a Toshiba Portege R500.

| * | toshiba_acpi: Only register backlight device when interface is read/writeSeth Forshee2012-05-311-24/+56
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Currently the backlight device is registered unconditionally, but many (probably most) Toshibas either don't support HCI_LCD_BRIGHTNESS or only support reading from it. This patch adds a test of HCI_LCD_BRIGHTNESS during initialization and only registers the backlight device if this interface supports both reads and writes.
