* wl18xx: add module parameter to disable TCP checksumLuciano Coelho2012-06-05
| | | | | | | Add a new module parameter to disable TCP checksum offload. Signed-off-by: Luciano Coelho <coelho@ti.com> Signed-off-by: Arik Nemtsov <arik@wizery.com>
* wl18xx: add number of antennas and dc2dc type as module paramsLuciano Coelho2012-06-05
| | | | | | | | | | | We need to specify the number of 2.4GHz and 5GHz antennas and whether the board has an internal or external DC2DC. Add some module parameters that allow changing that. In the future this will come from the "NVS" file. Signed-off-by: Luciano Coelho <coelho@ti.com> Signed-off-by: Arik Nemtsov <arik@wizery.com>
* wl18xx: change the low_band_component_type for HDK boardsLuciano Coelho2012-06-05
| | | | | | | | | Currently, all HDK boards use low_band_component_type 0x06. In the future this may change, but for now, we hardcode this value when the board_type is set to HDK. Signed-off-by: Luciano Coelho <coelho@ti.com> Signed-off-by: Arik Nemtsov <arik@wizery.com>
* wl18xx: add plt_init operationLuciano Coelho2012-06-05
| | | | | | | | Add the correct FW name for PLT (which is the same as the normal firmware) and implement the plt_init operation. Signed-off-by: Luciano Coelho <coelho@ti.com> Signed-off-by: Arik Nemtsov <arik@wizery.com>
* wl18xx: change board type enum according to new FWArik Nemtsov2012-06-05
| | | | | | | | Add more board types and remove a now unneeded write to SCR_PAD2 setting the board type. Signed-off-by: Arik Nemtsov <arik@wizery.com> Signed-off-by: Luciano Coelho <coelho@ti.com>
* wl18xx: don't upload NVS to FWArik Nemtsov2012-06-05
| | | | | | | | | In this chip family the NVS file should not be uploaded to FW. In fact, we encounter strange bugs (sdio errors) when trying to upload it with certain parameters. Signed-off-by: Arik Nemtsov <arik@wizery.com> Signed-off-by: Luciano Coelho <coelho@ti.com>
* wl18xx: init Tx-released index to 0 on HW initArik Nemtsov2012-06-05
| | | | | | | | This ensures the index is 0 on FW recovery and prevents spurious error prints - "WARNING illegal id in tx completion". Signed-off-by: Arik Nemtsov <arik@wizery.com> Signed-off-by: Luciano Coelho <coelho@ti.com>
* wl18xx: implement hw op to read PG versionArik Nemtsov2012-06-05
| | | | | | | | | Read the HW PG version of the 18xx chip from FUSE. Based on an earlier patch by Luciano Coelho <coelho@ti.com>. Signed-off-by: Arik Nemtsov <arik@wizery.com> Signed-off-by: Luciano Coelho <coelho@ti.com>
* wl18xx: read clock frequency and do top init accordinglyLuciano Coelho2012-06-05
| | | | | | | | | Instead of using hardcoded values for a single frequency, we need to read the frequency and use the appropriate values for it in the top initialization. Signed-off-by: Luciano Coelho <coelho@ti.com> Signed-off-by: Arik Nemtsov <arik@wizery.com>
* wl18xx: disable FW log functionalityArik Nemtsov2012-06-05
| | | | | | | Currently (Fw .67) appears to do more harm than good. Signed-off-by: Arik Nemtsov <arik@wizery.com> Signed-off-by: Luciano Coelho <coelho@ti.com>
* wl18xx: read FW pc on recoveryArik Nemtsov2012-06-05
| | | | | | | | | | Define the FW pc in the 18xx register translation table. This specific register is only valid in the boot partition, so change the momentarily change partitions. This doesn't damage 12xx cards, where the FW pc is accessible via boot partition as well. Signed-off-by: Arik Nemtsov <arik@wizery.com> Signed-off-by: Luciano Coelho <coelho@ti.com>
* wl18xx: translate and write the board type to SCR_PAD2Luciano Coelho2012-06-05
| | | | | | | | | | | The firmware uses the SCR_PAD2 register to read the board type passed from the driver. The values don't match the ones used in the mac and phy configuration, so we need to map them before writing. This commit adds a translation table that is used when writing the board type to SCR_PAD2. Signed-off-by: Luciano Coelho <coelho@ti.com> Signed-off-by: Arik Nemtsov <arik@wizery.com>
* wl18xx: add board type module argumentLuciano Coelho2012-06-05
| | | | | | | | | | | | | Different board types (ie. FPGA, HDK and DVP/EVB) require slightly different init configuration options. Since we cannot probe the type of board from the actual hardware, we need to pass it as an option during module load. This patch adds a module parameters that accepts the 3 different board types, with DVP/EVB as the default, and uses this value where needed.

* wl18xx: add module param for overriding HT capsArik Nemtsov2012-06-05
| | | | | | | | Set an alternate HT cap allowing MIMO rates (but only 20mhz) channels, when the module is loaded with ht_mode=mimo. Signed-off-by: Arik Nemtsov <arik@wizery.com> Signed-off-by: Luciano Coelho <coelho@ti.com>

| | | | | | | | | | | | Add a HW op to add extra enabled rates for AP-mode data-rates. Since the rates might depend on channel properties, reconfigure AP-mode rates when these change. Implement the HW op for the 18xx family, where MIMO or wide-chan rates can be added. Signed-off-by: Arik Nemtsov <arik@wizery.com> Signed-off-by: Luciano Coelho <coelho@ti.com>

* wlcore/wl18xx: add hw op for Rx HW checksumArik Nemtsov2012-06-05

* wlcore/wl18xx: add hw op for setting Tx HW checksumArik Nemtsov2012-06-05
