* omap2/3: ZOOM: Correcting key mapping for few keysVimal Singh2010-01-08
| | | | | | | | | | | | | Keys: 'right arrow', 'up arrow' and 'select' were mapped wrongly. This patch corrects them. This patch also adds one missing key present in the board, currently I added it as 'unknown' key, as I am not able to find proper description for this key. One key entry (r: 7, c: 5) is present in the keymap, which is really not present in the board, removing it.

* omap2/3: make serial_in_override() address the right uart portAlexander Shishkin2010-01-08
| | | | | | | | | | | | Commit f62349ee9788b1d94c55eb6c291d74a1f69bdd9e makes it possible to have some other than first uart port as ttyS0, which breaks the workaround serial_in_override() function which will try to address the first uart port (for ttyS0) and not the one that was initialized.

* omap1: Fix compile for omap1_bl.cTony Lindgren2010-01-08
| | | | | | | | | | | | | | | | Commit 9905a43b made struct backlight_ops const. Omap was setting check_fb dynamically, which caused the following compile error: drivers/video/backlight/omap1_bl.c: In function 'omapbl_probe': drivers/video/backlight/omap1_bl.c:142: error: assignment of read-only variable 'omapbl_ops' Turns out pdata->check_fb is not being used, so just remove it to fix the compile.

* omap: gpio: Simultaneously requested rising and falling edgeCory Maccarrone2010-01-08
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Some chips, namely any OMAP1 chips using METHOD_MPUIO, OMAP15xx and OMAP7xx, cannot be setup to respond to on-chip GPIO interrupts in both rising and falling edge directions -- they can only respond to one direction or the other, depending on how the ICR is configured. Additionally, current code forces rising edge detection if both flags are specified: if (trigger & IRQ_TYPE_EDGE_RISING) l |= 1 << gpio; else if (trigger & IRQ_TYPE_EDGE_FALLING) l &= ~(1 << gpio); else goto bad; This change implements a toggle function that will modify the ICR to flip the direction of interrupt for IRQs that are requested with both rising and falling flags. The toggle function is not called for chips and GPIOs it does not apply to through the use of a flip_mask that's added on a per-bank basis. The mask is only set for those GPIOs where a toggle is necessary. Edge detection starts out the same as above with FALLING mode first. The toggle happens on EACH interrupt; without it, we have the following sequence of actions on GPIO transition: ICR GPIO Result 0x1 0 -> 1 (rising) Interrupt 0x1 1 -> 0 (falling) No interrupt (set ICR to 0x0 manually) 0x0 0 -> 1 (rising) No interrupt 0x0 1 -> 0 (falling) Interrupt That is, with the ICR set to 1 for a gpio, only rising edge interrupts are caught, and with it set to 0, only falling edge interrupts are caught. If we add in the toggle, we get this: ICR GPIO Result 0x1 0 -> 1 (rising) Interrupt (ICR set to 0x0) 0x0 1 -> 0 (falling) Interrupt (ICR set to 0x1) 0x1 0 -> 1 ... so, both rising and falling are caught, per the request for both (IRQ_TYPE_EDGE_RISING | IRQ_TYPE_EDGE_FALLING).

The I model s_active count + completion as a sleeping read/write lock. I describe to lockdep sysfs_get_active as a read_trylock, sysfs_put_active as a read_unlock, and sysfs_deactivate as a write_lock and write_unlock pair. This seems to capture the essence for purposes of finding deadlocks, and in my testing gives finds real issues and ignores non-issues. This brings us back to holding locks over kobject_del is a problem that ideally we should find a way of addressing, but at least lockdep can tell us about the problems instead of requiring developers to debug rare strange system deadlocks, that happen when sysfs files are removed while being written to.

Turn it off by default in order to cut down on spurious bug reports. Signed-off-by: Paul Mundt <lethal@linux-sh.org>
| * | | | | | sh: Disable PMB for SH4AL-DSP CPUs.Paul Mundt2010-01-03
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | While the PMB is available on SH-4A parts, SH4AL-DSP parts exclude it altogether. As such, explicitly disable PMB support for these parts. If this changes in the future for newer subtypes, this will have to be made more fine-grained. Signed-off-by: Paul Mundt <lethal@linux-sh.org>
| * | | | | | sh: Only provide a PCLK definition for legacy CPG CPUs.Paul Mundt2009-12-28
| | |_|_|/ / | |/| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | As CPUs are migrated over to more fully-featured clock frameworks of their own and off of the legacy CPG code, they no longer have any real need for defining the PCLK value. The PCLK define in itself is already fairly misleading, as many boards get their input clocks from different sources, making this value fairly arbitrary anyways. Outside of the legacy CPG clock framework, the only place where this value is used is for deriving CLOCK_TICK_RATE, which we set back to the legacy PIT value that it was before the PCLK definitions were added in the first place.

This didn't matter as much when functions which managed the reserved metadata blocks were more aggressive about dropping reserved metadata blocks as delayed allocation blocks were written, but unfortunately they were too aggressive. This was fixed in commit 0637c6f, but as a result the over-estimation by ext4_calc_metadata_amount() would lead to reserving 2-3 times the number of pending delayed allocation blocks as potentially required metadata blocks. So if there are 1 megabytes of blocks which have been not yet been allocation, up to 3 megabytes of space would get reserved out of the user's quota and from the file system free space pool until all of the inode's data blocks have been allocated. This commit addresses this problem by much more accurately estimating the number of metadata blocks that will be required. It will still somewhat over-estimate the number of blocks needed, since it must make a worst case estimate not knowing which physical blocks will be needed, but it is much more accurate than before.
