2013-09-09rt2800: change initialization sequence to fix system freezeStanislaw Gruszka
My commit commit c630ccf1a127578421a928489d51e99c05037054 Author: Stanislaw Gruszka <stf_xl@wp.pl> Date: Sat Mar 16 19:19:46 2013 +0100 rt2800: rearrange bbp/rfcsr initialization make Maxim machine freeze when try to start wireless device. Initialization order and sending MCU_BOOT_SIGNAL request, changed in above commit, is important. Doing things incorrectly make PCIe bus problems, which can froze the machine. This patch change initialization sequence like vendor driver do: function NICInitializeAsic() from 2011_1007_RT5390_RT5392_Linux_STA_V2.5.0.3_DPO (PCI devices) and DPO_RT5572_LinuxSTA_2.6.1.3_20121022 (according Mediatek, latest driver for RT8070/RT3070/RT3370/RT3572/RT5370/RT5372/RT5572 USB devices). It fixes freezes on Maxim system.

The HW_BEACON_BASE() macro returns the base address of a given beacon, however the returned values are not usable on all chipsets. On devices which have selectable shared memory parts, some beacon may be located in the high part of the shared memory. Instead of extending the already complicated macro, add a new helper function and use that to get the base address of a given beacon. The actual patch contains no functional changes, the helper function will be extended in a further patch to handle different chipsets' requirements.

2013-07-29rt2x00: fix stop queueStanislaw Gruszka
Since we clear QUEUE_STARTED in rt2x00queue_stop_queue(), following call to rt2x00queue_pause_queue() reduce to noop, i.e we do not stop queue in mac80211. To fix that introduce rt2x00queue_pause_queue_nocheck() function, which will stop queue in mac80211 directly. Note that rt2x00_start_queue() explicitly set QUEUE_PAUSED bit. Note also that reordering operations i.e. first call to rt2x00queue_pause_queue() and then clear QUEUE_STARTED bit, will race with rt2x00queue_unpause_queue(), so calling ieee80211_stop_queue() directly is the only available solution to fix the problem without major rework.

2013-07-22rt2x00: rt2800lib: add EEPROM map for the RT3593 chipsetGabor Juhos
Three-chain devices are using a different EEPROM layout than the rest of the chipsets. Add a new map which describes the new layout and use that for the RT3593 chipset. The index values has been computed from the EEPROM_EXT_* defines, which can be found in the 'include/chip/rt3593.h' file in the Ralink DPO_RT5572_LinuxSTA_2.6.0.1_20120629 driver.

2013-07-22rt2x00: rt2800lib: introduce rt2800_eeprom_word_index helperGabor Juhos
Instead of assign the offset value to the enum directly use a new helper function to convert a rt2800_eeprom_word enum into an index of the rt2x00_dev->eeprom array. The patch does not change the existing behaviour, but makes it possible to add support for three-chain devices which are using a different EEPROM layout.

2013-07-22rt2x00: rt2800lib: introduce rt2800_eeprom_read_from_array helperGabor Juhos
Add a new helper function and use that for reading single elements of various arrays in the EEPROM. The patch does not change the current behaviour, but it allows to use sequential values for the rt2800_eeprom_word enums. The conversion will be implemented in a subsequent change.

2013-07-22rt2x00: rt2800lib: introduce local EEPROM access functionsGabor Juhos
The patch adds rt2800 specific functions for EEPROM data access and changes the code to use these instead of the generic rt2x00_eeprom_* variants. To avoid functional changes, the new functions are wrappers around the corresponding generic rt2x00_eeprom_* routines for now. Functional changes will be implemented in additional patches.
