* | | ath5k: Fix modinfo does not list alias -> pci-id linesSedat Dilek2010-12-09
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The AHB bus support patchset moved the table "Known PCI ids" from base.c to pci.c - unfortunately, MODULE_DEVICE_TABLE() was not transferred. With this fix 'modinfo ath5k' lists the alias -> pci-id lines, again. The issue was introduced by: commit e5b046d86fac609f636d127a38de94a175c7e83b "ath5k: Move PCI bus functions to separate file."

* | ath5k: Set turbo bit on rf bank 2Nick Kossifidis2010-11-30
| | | | | | | | | | | | | | | | | | | | | | | | | | | | * A diff between rfbuffer settings of turbo and non-turbo modes indicates there is a bit on bank 2 related to turbo operation (it's set on turbo modes). This bit is present on all radios except RF5413 that seems to have a completely different bank 2. Also since 2317 has the same rf-registers locations with 2425 and since the bit exists on 2317 I assume it also exists on 2425/2417). So in case we use turbo mode (40MHz) enable it on bank modification. Signed-off-by: Nick Kossifidis <mickflemm@gmail.com> Signed-off-by: John W. Linville <linville@tuxdriver.com>

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | * Add synth-only channel change for AR2413/5413. When we call ath5k_reset with a channel ath5k_hw_reset will first try to set channel on PHY while PHY is running instead of doing a normal full reset. To do this phy_init has to change to implement this functionality. * Clean up change_channel flag, what it really did was skip PCU registers when setting initvals. This is done because on reset PCU registers are not affected (except the registers we set in pcu init and -due to hw problems- TSF). Use a new skip_pcu flag that's not misleading instead. In the future we might use that to also skip PCU reset and save us the TSF etc problems (needs testing because standard practice is to reset everything). * Use fast channel change only when setting channel, and set skip_pcu to false only on init. When we reset the card due to DMA or PHY problems skip pcu but never do a fast channel change. Signed-off-by: Nick Kossifidis <mickflemm@gmail.com> Signed-off-by: John W.
