* b43: Add LP PHY Analog Switch SupportThomas Ilnseher2009-09-23
| | | | | | | | | | | | | | | | | The current verison of b43 uses "b43_phyop_switch_analog_generic" for A, G and LP phys. According to the spec, this is the wrong behaviour for the LP PHY (see: http://bcm-v4.sipsolutions.net/802.11/PHY/Anacore ) While no problems on the x86 plattform where seen, this leads to a crash on the BCM5354 SoC (MIPS 32 LE plattform). This patch implements the analog switch for LP PHYs according to the specs. It fixes the crash signed-off-by: Thomas Ilnseher <illth@gmx.de> Signed-off-by: John W. Linville <linville@tuxdriver.com>
* b43: Add myself to module authors & to LP-PHY file copyright noticesGábor Stefanik2009-08-31
| | | | | | | | Also mark the LP-PHY driver "802.11a/g" instead of "802.11g", as LP-PHY is capable of both 2GHz and 5GHz operation. Signed-off-by: Gábor Stefanik <netrolller.3d@gmail.com> Signed-off-by: John W. Linville <linville@tuxdriver.com>
* b43: Implement antenna diversity support for LP-PHYGábor Stefanik2009-08-28
| | | | | | | | | | The A/G-PHY changes are fallout fixes from the enum change, which in turn allows the LP-PHY code to be much simpler. The antenna_to_phyctl change is a fix for a potential existing bug that this patch may otherwise trigger. Signed-off-by: Gábor Stefanik <netrolller.3d@gmail.com> Signed-off-by: John W.

* b43: LP-PHY: Revert to the original PHY register write routineGábor Stefanik2009-08-28
| | | | | | | | After some discussion on IRC about the PHY register write change, I am not sure anymore if this is the right thing to do. Signed-off-by: Gábor Stefanik <netrolller.3d@gmail.com> Signed-off-by: John W. Linville <linville@tuxdriver.com>
* ssb: Implement PMU LDO control and use it in b43Gábor Stefanik2009-08-28
| | | | | | | | Implement the "PMU LDO set voltage" and "PMU LDO PA ref enable" functions, and use them during LP-PHY baseband init in b43. Signed-off-by: Gábor Stefanik <netrolller.3d@gmail.com> Signed-off-by: John W. Linville <linville@tuxdriver.com>
* b43: Fix and update LP-PHY codeGábor Stefanik2009-08-28
| | | | | | | | | | | | | | | | | | | | -Fix a few nasty typos (b43_phy_* operations instead of b43_radio_*) in the channel tune routines. -Fix some typos & spec errors found by MMIO tracing. -Optimize b43_phy_write & b43_phy_mask/set/maskset to use only the minimal number of MMIO accesses. (Write is possible using a single 32-bit MMIO write, while set/mask/maskset can be done in 3 16-bit MMIOs). -Set the default channel back to 1, as the bug forcing us to use channel 7 is now fixed. With this, the device comes up, scans, associates, transmits, receives, monitors and injects on all channels - in other words, it's fully functional. Sensitivity and TX power are still sub-optimal, due to the lack of calibration (that's next on my list). Signed-off-by: Gábor Stefanik <netrolller.3d@gmail.com> Signed-off-by: John W. Linville <linville@tuxdriver.com>
* b43: LP-PHY: Fix and simplify Qdiv roundupGábor Stefanik2009-08-28
| | | | | | | | | | | | The Qdiv roundup routine is essentially a fixed-point division algorithm, using only integer math. However, the version in the specs had a major error that has been recently fixed (a missing quotient++). Replace Qdiv roundup with a rewritten, simplified version.

* b43: LP-PHY: Fix a few typos in the RC calibration codeGábor Stefanik2009-08-28
| | | | | | | | | The RC calibration code has some typos - fix them. Also, make the default channel 7, as channel 1 is still broken (only channels 7 and 8, and occasionally 9 work). Signed-off-by: Gábor Stefanik <netrolller.3d@gmail.com> Signed-off-by: John W. Linville <linville@tuxdriver.com>
* b43: LP-PHY: Implement spec updates and remove resolved FIXMEsGábor Stefanik2009-08-20
| | | | | | | | | | | | Larry has started re-checking all current routines against a new version of the Broadcom MIPS driver. This patch implements the first round of changes he documented on the specs wiki. Also remove a few FIXMEs regarding missing initial values for variables with dynamic initial values where reading the values has been implemented.

* b43: LP-PHY: Two small spec updatesGábor Stefanik2009-08-20
| | | | | | | | | | | | The specs are beginning to support rev3 LP-PHYs - implement one of the changes needed for rev3 support. Also, in the new MIPS driver, the "Japan TX filter" was renamed to "analog TX filter init" - however, calling it "init" is confusing, so name it "set analog filter", with a comment for easier future identification.

* b43: LP-PHY: Update baseband init for recent spec changesGábor Stefanik2009-08-20
| | | | | | | | | | | | | | The spec had some nasty typos, and a large part of the rev0/1 BB init procedure was also missing. Fix these. Also make the init-time channel switch debuggable. (The change from -EINVAL to -EIO is simply to make it possible to distinguish the PLL charge pump error from a channel-not-found error.)

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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.
