2013-10-18rt2x00: rt2800pci: use module_pci_driver macroGabor Juhos1-13/+1
Use the module_pci_driver() macro to make the code simpler by eliminating module_init and module_exit calls. Signed-off-by: Gabor Juhos <juhosg@openwrt.org> Signed-off-by: John W. Linville <linville@tuxdriver.com>
2013-10-18rt2x00: rt2800pci: move SoC specific code into a separate moduleGabor Juhos4-245/+284
The PCI and SoC specific drivers are using separate code now so it is not reasonable to use the same module for both drivers anymore. Signed-off-by: Gabor Juhos <juhosg@openwrt.org> Signed-off-by: John W. Linville <linville@tuxdriver.com>
2013-10-18rt2x00: rt2800pci: use separate hwcrypt_disabled callback for SoC devicesGabor Juhos1-2/+7
The 'rt2800pci_hwcrypt_disabled' function is the only PCI specific callback which is used by the SoC driver. Create a clone of that to get rid of the dependency. Even though the two functions are using the same variable, but the SoC specific code will be moved into a separate module which will have its own 'modparam_nohwcrypt' variable.

2013-10-18rt2x00: rt2800pci: move rt2800mmio_enable_radio function to another moduleGabor Juhos3-13/+18

2013-10-18rt2x00: rt2800pci: split rt2800pci_enable_radio functionGabor Juhos1-7/+12
The function is called for PCI and SoC devices however the MCU related part of the function has no effect on SoC devices. Move the common part of the function into a separate helper and use that for the SoC devices. Signed-off-by: Gabor Juhos <juhosg@openwrt.org> Signed-off-by: John W. Linville <linville@tuxdriver.com>
2013-10-18rt2x00: rt2800pci: rename rt2800pci_disable_radio functionGabor Juhos1-11/+8
The function contain code for SoC devices only. Rename the function to 'rt2800soc_disable_radio' and move it to the SoC specific section. Use the renamed function in the SoC specific code only and remove the 'if rt2x00_is_soc(rt2x00dev)' condition from the function body.

2013-10-18rt2x00: rt2800pci: use separate set_state callback for SoC devicesGabor Juhos1-2/+41
The 'rt2800pci_set_state' function uses MCU commands to set the device state, however these have no effect on SoC devices. Use a different set_state callback which does not use the MCU fcuntions.

2013-10-18rt2x00: rt2800pci: use separate read_eeprom callback for SoC devicesGabor Juhos1-40/+16
Rename the 'rt2800pci_read_eeprom_soc function' to 'rt2800soc_read_eeprom' and use that directly in the SoC specific 'rt2800_ops' structure. Also move the 'rt2800pci_eeprom_read' function into an 'ifdef PCI' section and remove the 'rt2800pci_read_eeprom_soc' call from that. Additionally, remove the dummy inline eeprom functions. Those are not used anymore. Signed-off-by: Gabor Juhos <juhosg@openwrt.org> Signed-off-by: John W. Linville <linville@tuxdriver.com>
2013-10-18rt2x00: rt2800pci: use separate ops for the SoC driverGabor Juhos1-2/+102

2013-10-18rt2x00: rt2800lib: autodetect 5GHz band supportGabor Juhos1-4/+4
If the RF chip supports more than 14 channels that indirectly means that it supports the 5GHz band.

2013-10-18rt2800usb: slow down TX status pollingStanislaw Gruszka1-4/+8
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.

2013-10-14rt2x00: add rt2x00_has_cap_* helpersGabor Juhos1-0/+87
The rt2x00 code directly accesses the 'cap_flags' field of 'struct rt2x00_dev' when checking presence of a given capability flag. The direct access needs long expressions which lowers readability of the code. Add a few helper functions which can be used to test device capabilities without directly accessing the cap_flags filed.

The Ralink DPO_RT5572_LinuxSTA_2.6.1.3_20121022 reference driver uses different RSSI threshold and VGC adjustment values for the RT3572 and RT3593 chipsets.

2013-10-10rt2x00: rt2800lib: fix VGC adjustment for RT5592Gabor Juhos1-4/+7
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 Gruszka2-31/+8
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 Juhos1-4/+11
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.

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.

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.
