From d70357d56942fa587e39505547cb69e10a8d59a0 Mon Sep 17 00:00:00 2001 From: "Luis R. Rodriguez" Date: Thu, 15 Apr 2010 17:38:06 -0400 Subject: ath9k_hw: start building an abstraction layer for hardware routines ath9k supports the AR5008, AR9001 and AR9002 family of Atheros chipsets, all 802.11n. The new breed of 802.11n chips, the AR9003 family will be supported as well soon. To help with its support we're going to add a few callbacks for hardware routines which differ considerably instead of adding branch checks for the revision at runtime. Signed-off-by: Luis R.

Rodriguez" Date: Thu, 15 Apr 2010 17:38:13 -0400 Subject: ath9k_hw: remove wrapper ath9k_hw_write_regs() 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.

Since all INI stuff is now moved out hw.c no longer needs to include and touch any original INI headers/structs. Signed-off-by: Luis R. Rodriguez Signed-off-by: John W.

Rodriguez" Date: Thu, 15 Apr 2010 17:39:13 -0400 Subject: ath9k_hw: restore mac address reading logic Once upon a time the AR_EEPROM_MAC macro was added to let us add a random attribute to the three 4-bytes of MAC addresses entries we read from the EEPROM. This was good while a random high-enough value was used which did not conflict with any of the already existing enum eeprom_param values. With AR9003 support the enums overlap and it means we either increment the random offset or just restore the reading logic to match what the HAL has. I choose to do the later to synchronize the logic on both code bases. This should fix reading the MAC address from the EEPROM on AR9003 hardware. Signed-off-by: Luis R.

It has been tested in an IBSS network where artifical IBSS merges have been done in order to trigger hundreds of rollover for the TSF lower part. It follows the logic mentionned by Derek, with only 2 register reads needed at each additional steps instead of 3 (the minimum number of register reads is still 3).
