2012-06-05wlcore/wl12xx: move ref_clock and tcxo_clock elements to wl12xxLuciano Coelho
Only wl12xx needs to get the ref_clock anc tcxo_clock values from the platform data. Move these elements from the wl1271 structure to wl12xx's private data. Signed-off-by: Luciano Coelho <coelho@ti.com> Signed-off-by: Arik Nemtsov <arik@wizery.com>
2012-06-05wlcore: rename wl12xx.h to wlcore_i.hLuciano Coelho
The wl12xx.h file now contains mostly definitions that are internal to wlcore. Still, some things need to me moved to the public header, so for now we keep including it in wlcore.h. Signed-off-by: Luciano Coelho <coelho@ti.com> Signed-off-by: Arik Nemtsov <arik@wizery.com>

2012-06-05wl18xx: read FW pc on recoveryArik Nemtsov
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>
2012-06-05wl18xx: translate and write the board type to SCR_PAD2Luciano Coelho
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>
2012-06-05wl18xx: add board type module argumentLuciano Coelho
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.

2012-06-05wlcore/wl18xx: add hw op for Rx HW checksumArik Nemtsov

2012-06-05wlcore_sdio/wl18xx: use SDIO revision number to identify wl18xx chipsLuciano Coelho
At least in PG1, the wl18xx chips use the same SDIO vendor/device ID, so it's not possible to figure out which driver is to be used. As a workaround, we can check the SDIO revision number, because wl18xx uses 3.00 and wl12xx does not. Signed-off-by: Luciano Coelho <coelho@ti.com> Signed-off-by: Arik Nemtsov <arik@wizery.com>

2012-05-25wl1251: fix oops on early interruptGrazvydas Ignotas
This driver disables interrupt just after requesting it and enables it later, after interface is up. However currently there is a time window between request_irq() and disable_irq() where if interrupt arrives, the driver oopses because it's not yet ready to process it. This can be reproduced by inserting the module, associating and removing the module multiple times. Eliminate this race by setting IRQF_NOAUTOEN flag before request_irq().
