* rfkill: rewriteJohannes Berg2009-06-032-16/+15
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This patch completely rewrites the rfkill core to address the following deficiencies: * all rfkill drivers need to implement polling where necessary rather than having one central implementation * updating the rfkill state cannot be done from arbitrary contexts, forcing drivers to use schedule_work and requiring lots of code * rfkill drivers need to keep track of soft/hard blocked internally -- the core should do this * the rfkill API has many unexpected quirks, for example being asymmetric wrt. alloc/free and register/unregister * rfkill can call back into a driver from within a function the driver called -- this is prone to deadlocks and generally should be avoided * rfkill-input pointlessly is a separate module * drivers need to #ifdef rfkill functions (unless they want to depend on or select RFKILL) -- rfkill should provide inlines that do nothing if it isn't compiled in * the rfkill structure is not opaque -- drivers need to initialise it correctly (lots of sanity checking code required) -- instead force drivers to pass the right variables to rfkill_alloc() * the documentation is hard to read because it always assumes the reader is completely clueless and contains way TOO MANY CAPS * the rfkill code needlessly uses a lot of locks and atomic operations in locked sections * fix LED trigger to actually change the LED when the radio state changes -- this wasn't done before Tested-by: Alan Jenkins <alan-jenkins@tuffmail.co.uk> Signed-off-by: Henrique de Moraes Holschuh <hmh@hmh.eng.br> [thinkpad] Signed-off-by: Johannes Berg <johannes@sipsolutions.net> Signed-off-by: John W.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This is a build fix, resyncing the DaVinci EVM ASoC board code with the version in the DaVinci tree. That resync includes support for the DM355 EVM, although that board isn't yet in mainline.

The MOVW and MOVT are both load-immediate instructions, MOVW loads 16 bits into the bottom half of a register, and MOVT loads 16 bits into the top half of a register. The relocation information for these instructions has a full 32 bit value, plus an addend which is stored in the 16 immediate bits in the instruction itself. The immediate bits in the instruction are not contiguous (the register # splits it into a 4 bit and 12 bit value), so the addend has to be extracted accordingly and added to the value. The value is then split and put into the instruction; a MOVW uses the bottom 16 bits of the value, and a MOVT uses the top 16 bits.

The compatibilities are a bit different based on which kernel was used previously + Users of TI/MV kernels no longer see mtd2 "params" (mainline u-boot env is in a different place) * Filesystem is now mtd2 ... vs mtd3 + Users of GIT kernels now see mtd0 and mtd1 partitions * Filesystem partition starts 640 KBytes earlier * Filesystem is now mtd2 ... vs mtd0 * Linux now *uses* the flash-resident BBT * Removes annoying slowdown/hiccup during boot * Potentially ~64KB less space available with TI/MV kernels If you *used* NAND partitions from Linux, there is no solution that's fully compatible with all previous kernels in those respects ... ergo this "best compromise".

So for example on dm6467, GPIO-42 is the last GPIO, and trying to use GPIO-43 now fails cleanly; or GPIO-72 on dm6446. - Enable GPIO interrupts on each 16-bit GPIO-irq bank ... previously, only the first five were enabled, so GPIO-80 and above (on dm355) wouldn't trigger IRQs. - Use the right IRQ for each GPIO bank. The wrong values were used for dm355 chips, so GPIO IRQs got routed incorrectly. - Handle up to four pairs of 16-bit GPIO banks ... previously only three were handled, so accessing GPIO-96 and up (e.g. on dm355) would oops. - Update several comments that were dm6446-specific. Verified by receiving GPIO-1 (dm9000) and GPIO-5 (msp430) IRQs on the DM355 EVM. One thing this doesn't do is handle the way some of the GPIO numbers on dm6467 are reserved but aren't valid as GPIOs. Some bitmap logic could fix that if needed. Signed-off-by: David Brownell <dbrownell@users.sourceforge.net> Signed-off-by: Kevin Hilman <khilman@deeprootsystems.com>
