The AR9130 is an AR9160/AR5416 family WMAC which is glued directly to the AR913x SoC peripheral bus (APB) rather than via a PCI/PCIe bridge. The specifics: * A new build option is required to use the AR9130 - AH_SUPPORT_AR9130. This is needed due to the different location the RTC registers live with this chip; hopefully this will be undone in the future. This does currently mean that enabling this option will break non-AR9130 builds, so don't enable it unless you're specifically building an image for the AR913x SoC. * Add the new probe, attach, EEPROM and PLL methods specific to Howl. * Add a work-around to ah_eeprom_v14.c which disables some of the checks for endian-ness and magic in the EEPROM image if an eepromdata block is provided. This'll be fixed at a later stage by porting the ath9k probe code and making sure it doesn't break in other setups (which my previous attempt at this did.) * Sprinkle Howl modifications throughput the interrupt path - it doesn't implement the SYNC interrupt registers, so ignore those. * Sprinkle Howl chip powerup/down throughout the reset path; the RTC methods were * Sprinkle some other Howl workarounds in the reset path. * Hard-code an alternative setup for the AR_CFG register for Howl, that sets up things suitable for Big-Endian MIPS (which is the only platform this chip is glued to.) This has been tested on the AR913x based TP-Link WR-1043nd mode, in legacy, HT/20 and HT/40 modes. Caveats: * 2ghz has only been tested. I've not seen any 5ghz radios glued to this chipset so I can't test it. * AR5416_INTERRUPT_MITIGATION is not supported on the AR9130. At least, it isn't implemented in ath9k. Please don't enable this. * This hasn't been tested in MBSS mode or in RX/TX block-aggregation mode.
