* iwl3945: remove unnecessary call to apm_ops.reset()Ben Cahill2009-10-27
| | | | | | | | | | | | | | Now that we're unconditionally using apm_ops.stop() to reset and power-down the device in __iwl3945_down(), the apm_ops.reset() is redundant. Removing this call will also allow us to remove iwl3945_apm_reset(). Remove unneeded iwl_clear_bit(CSR_GP_CNTRL_REG_FLAG_MAC_ACCESS_REQ) because this bit will be set again very soon in iwl3945_hw_txq_ctx_stop() and other following calls.

* iwlwifi: turn off device when not used.Ben Cahill2009-10-27
| | | | | | | | | | | | | | | | | | | | | | | | | | | In some cases (e.g. when mac80211 calls iwl_mac_stop() for suspend or user no longer wants device active), device has not been going into low power state via __iwl_down(). apm_ops.reset() does not put device into low power state; instead it resets the device, then puts it into a powered-up state ready to be re-loaded with uCode and re-started. This has needlessly warmed up user's laptops and drained batteries. With current architecture in which mac80211 controls device up/down (including resetting device after firmware errors), there is no need for apm_ops.reset() any more; apm_ops.reset() is basically a combination of apm_ops.stop() and apm_ops.init(). Instead, __iwl_down() now unconditionally places the device into a low-power state via apm_ops.stop(). Device may be re-started via __iwl_up() calling apm_ops.init() as soon as it may be needed (e.g. quickly for firmware errors), but in the meantime, device will stop wasting energy. Note that, even in this low power state, if driver re-enables interrupts, the device retains the ability to sense the hardware RF-KILL switch, and (except for 3945) interrupt the host when it changes.

* iwl3945: update iwl3945_apm_init()Ben Cahill2009-10-27
| | | | | | | | | | | | | | | | | Update iwl3945_apm_init() to set up device registers in sequence most recently recommended by factory. Add resets for APMG interrupts and radio chip, formerly done only in iwl3945_apm_reset(); moving them here assures that apm_init() will do a complete job of preparing hardware not only after platform boot, but also after apm_stop() has executed (due to rfkill, ifconfig down, driver unload, etc.). This is in preparation to completely remove apm_reset(). Add some comments.
