* ath9k_hw: Move some RF ops to the private callbacksLuis R. Rodriguez2010-04-161-961/+0
| | | | | | | | | | | | | | The PHY split is easier done in a few steps. First move the RF ops to the private ops and rename them accordingly. We split PHY stuff up first for the AR5008 and AR9002 families. There are some callbacks that AR9002 share with the AR5008 familiy so we set those first, if AR9002 has some different callbacks it will override them upon hardware init.

* ath9k_hw: remove wrapper ath9k_hw_write_regs()Luis R. Rodriguez2010-04-161-15/+0
| | | | | | | | | | | | | | | | | | | | | | | This is used only once by ath9k_hw_process_ini() to write an array of phy registers through REG_WRITE_ARRAY(), but we already call REG_WRITE_ARRAY() multiple times on the same caller so just remove this pointless wrapper. We'll eventually just move the ath9k_hw_process_ini() caller as an callback to abstract away between different hardware families. Although this change is subtle I should note that this does change the delay pattern on writing the next series of registers. REG_WRITE_ARRAY() uses a counter for each register write and does a udelay(1) every 64 writes. By removing this call it means that the counter is processed for all the iniBB_RfGain registers and is incremented on ath9k_hw_process_ini(), before this the after the call ath9k_hw_write_regs() was made the register counter was kept at the same index number prior to the call.

* ath9k: Remove a few unused functionsSujith2009-11-181-90/+0
| | | | | | | | | | | ATH9K_ANT_VARIABLE is the default diversity control used. Consequently ath9k_hw_decrease_chain_power() does nothing. ath9k_hw_setantennaswitch() is unused too. Also, gbeacon_rate is unused. Signed-off-by: Sujith <Sujith.Manoharan@atheros.com> Signed-off-by: John W. Linville <linville@tuxdriver.com>

* ath9k_hw: Fix and complete force bias for AR5416Luis R. Rodriguez2009-10-301-0/+70
| | | | | | | | | | | | | | | | Force bias is a fix for usage of AR5416 radios on the 2.4 GHz band for orientation sensitivity. This was only partially implemented with the ath9k_hw_decrease_chain_power() but first -- this was being called for all chipsets which is not correct and second -- it was missing the actual orientation code. We now ensure to only enable force bias only for AR5416 and BUG_ON() on other chipsets. Although ath9k_hw_decrease_chain_power() was enabled for newer chipsets I suspect that it never ran unless the EEPROM had ATH9K_ANT_FIXED_A or ATH9K_ANT_FIXED_B for antenna diversity.

* ath9k_hw: order phy.c code and integrate spur mitigationLuis R. Rodriguez2009-10-301-156/+623
| | | | | | | | | | | This reorders phy.c routines in the order in the order in which they are used and also moves the spur mitigation helpers for each type of chip into phy.c as they are RF related. This patch has no functional changes. Signed-off-by: Luis R. Rodriguez <lrodriguez@atheros.com> Signed-off-by: John W. Linville <linville@tuxdriver.com>

* ath9k_hw: simplify rf attach and rename to ath9k_hw_rf_alloc_ext_banks()Luis R. Rodriguez2009-10-301-12/+7
| | | | | | | | | | | | | ath9k_hw_rfattach() was just calling a helper and this helper was doing nothing for single-chip devices, and for non single-chip devices it is just allocating memory for banks to program the RF registers at a later time. Simplify this by having the hw initialization call the rf bank allocation directly for external radios. Also, propagate an -ENOMEM properly now upon failure. Signed-off-by: Luis R.

* ath9k_hw: start documenting 802.11n RF anlong front endsLuis R. Rodriguez2009-10-301-5/+161
| | | | | | | | | | | | | | | | | | | | | | Document what we can about the RF analog front ends (radios) of Atheros 802.11n devices. What should be clearer now is the what we do for old pre AR5416 and AR5418 MAC based devices in comparison to the modern sigle-chip 802.11n solutions. All devices after AR9280 are single chip and require less programming -- the RF registers no longer need to be initialized as they all have the RF analog front end embedded together with the MAC/BB; this includes the AR9271. Older devices such as the ones with the AR5416 MACs (PCI) or AR5418 MACs (PCI-E) have an external 2.4 GHz AR2133 radio or a dual band 2.4 GHz / 5 GHz AR5133 radio. These external radios require additional programming of the RF registers. Clarify which parts are for what devices and which code is shared. This patch has no functional changes.

* ath9k: Update INI release for AR9287Sujith2009-10-071-7/+18
| | | | | | | | | | | | | If the current channel is between 2412 and 2472 MHz and if the channel is changing to 2484 MHz, then the registers 0xa1f4, 0xa1f8 and 0xa1fc need to be programmed to the "japan_2484" values. Conversely, if the current channel is 2484 MHz and if the channel is changing to one between 2412 and 2472 MHz, then the three registers need to be programmed to the "normal" values. This is needed for compliance with Japanese regulatory requirements. Signed-off-by: Sujith <Sujith.Manoharan@atheros.com> Signed-off-by: John W. Linville <linville@tuxdriver.com>
