2013-10-18rt2x00: rt2800pci: use rt2800mmio prefix for interrupt functionsGabor Juhos
The functions are used for devices with memory mapped I/O and contain no PCI specific code at all. Use rt2800mmio prefix instead of rt2800pci in the function names to reflect that. The patch contains no functional changes. Signed-off-by: Gabor Juhos <juhosg@openwrt.org> Signed-off-by: John W. Linville <linville@tuxdriver.com>

2013-10-18rt2x00: rt2800lib: autodetect 5GHz band supportGabor Juhos
If the RF chip supports more than 14 channels that indirectly means that it supports the 5GHz band. Use this fact to enable 5GHz band support instead of setting SUPPORT_BAND_5GHZ separately for each RF chip. Also move the setup code of the 2GHz band to the same place.

2013-10-18rt2800usb: slow down TX status pollingStanislaw Gruszka
Polling TX statuses too frequently has two negative effects. First is randomly peek CPU usage, causing overall system functioning delays. Second bad effect is that device is not able to fill TX statuses in H/W register on some workloads and we get lot of timeouts like below: ieee80211 phy4: rt2800usb_entry_txstatus_timeout: Warning - TX status timeout for entry 7 in queue 2 ieee80211 phy4: rt2800usb_entry_txstatus_timeout: Warning - TX status timeout for entry 7 in queue 2 ieee80211 phy4: rt2800usb_txdone: Warning - Got TX status for an empty queue 2, dropping This not only cause flood of messages in dmesg, but also bad throughput, since rate scaling algorithm can not work optimally. In the future, we should probably make polling interval be adjusted automatically, but for now just increase values, this make mentioned problems gone.

In commit 3d81535ea5940446510a8a5cee1c6ad23c90c753 (rt2800: 5592: add chip specific vgc calculations) the rt2800_link_tuner function has been modified to adjust VGC level for the RT5592 chipset. On the RT5592 chipset, the VGC level must be adjusted only if rssi is greater than -65. However the current code adjusts the VGC value by 0x10 regardless of the actual chipset if the rssi value is between -80 and -65. Fix the broken behaviour by reordering the if-else statements.

2013-10-10rt2x00: do not pause queue on flushStanislaw Gruszka
Pausing queue on flush make no sense since txdone procedure un-pause queue. Before flush procedure we have to assure queue is stopped, i.e. on receive path h/w RX is disabled, on transmit path queue is disabled in mac80211. That conditions are true except one function: rt2x00usb_watchdog_tx_dma(), so add stop/start queue there. Note stop/start queue can be racy if we do this from multiple paths, but currently we stop TX queues only on rt2x00lib_disable_radio(), which also stop/sync watchdog, hance we have no race condition.

2013-10-10rt2x00: rt2800lib: fix default VGC values for RT3572 for the 5GHz bandGabor Juhos
The rt2x00 driver uses 0x22 as a default VGC value in VGC adjustment for the RT3572 chipset. In the Ralink DPO_RT5572_LinuxSTA_2.6.1.3_20121022 driver, this value is only used for initialization. During VGC adjustment, the reference driver uses different values. Update the 'rt2800_get_default_vgc' function to synchronize the values with the reference driver. Also add the missing AGC initialization code into the 'rt2800_config_channel' function.

2013-10-10rt2x00: rt2800lib: fix VGC programming for RT3572 and RT3593Gabor Juhos
According to the DPO_RT5572_LinuxSTA_2.6.1.3_20121022 reference driver, programming of the 'BBP 66' register on the RT3572 and RT3593 chipsets must be done via the 'rt2800_bbp_write_with_rx_chain' function. This ensures that value is correclty set for all RX chains.

2013-10-10rt2x00: rt2800lib: remove TXMIXER_GAIN entries from the extended EEPROM mapGabor Juhos
The comments are indicating that the TXMIXER_GAIN_BG and TXMIXED_GAIN_A entries are overlapping with the RSSI_BG2 and RSSI_A2 entries in the extended EEPROM map. This is not correct, because the upper byte of the RSSI_BG2 and RSSI_A2 entries are reserved. There are no TX mixer gain values are stored at all in the extended EEPROM. Remove the initialization of these entries from the extended EEPROM map to reflect this.

The band selection and PE control code for the RT3593 chipsets only handles USB based devices currently. Due to this limitation RT3593 based PCIe cards are not working correctly. On PCIe cards band selection is controlled via GPIO #8 which is identical to the USB devices. The LNA PE control is slightly different, all LNA PEs are controlled by GPIO #4.
