2013-10-18rt2x00: rt2800pci: move SoC specific code into a separate moduleGabor Juhos
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 Juhos
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 Juhos

2013-10-18rt2x00: rt2800pci: split rt2800pci_enable_radio functionGabor Juhos
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 Juhos
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 Juhos

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>

2013-10-18ath9k: add TX99 supportLuis R. Rodriguez
TX99 support enables Specific Absorption Rate (SAR) testing. SAR is the unit of measurement for the amount of radio frequency(RF) absorbed by the body when using a wireless device. The RF exposure limits used are expressed in the terms of SAR, which is a measure of the electric and magnetic field strength and power density for transmitters operating at frequencies from 300 kHz to 100 GHz. Regulatory bodies around the world require that wireless device be evaluated to meet the RF exposure limits set forth in the governmental SAR regulations.
