2012-06-22wlcore: Force checking of io functions' return valuesIdo Yariv
All io functions' return values should be propagated and handled. Add a __must_check annotation to verify that the return values are checked and to avoid future mistakes. Signed-off-by: Ido Yariv <ido@wizery.com> Signed-off-by: Luciano Coelho <coelho@ti.com>

2012-06-22wlcore: Propagate errors from wl1271_raw_read32Ido Yariv

2012-06-21wl18xx: sane defaults for HT capabilitiesArik Nemtsov
Introduce a default set of HT capabilities that are set according to the number of antennas on the board. Move the HT setting code down to allow the number of antennas to be set (and optionally overridden) before it. Remove the "mimo" HT option, since the default mode now enables MIMO is possible. Use this opportunity to add a helper function for setting HT capabilities and reduce the volume of the code a bit.

2012-06-21wlcore: allow setting sleep_auth before interface initArik Nemtsov
Hold a value for sta_sleep_auth that is amenable to change by debugfs. When detecting a legal value in this variable on interface init, use it as an override value for sleep_auth. This makes debugging more intuitive using the debugfs value. Increment the conf version since we added an element to the conf structure. Note: An AP going up will always set sleep_auth to PSM_CAM.

2012-06-13wlcore/wl12xx: add support for HP and SKW FEM radio manufacturersYair Shapira
Add support for HP (High Performance TQS fem type 3) and SKW (fem type 2). This is done by increasing the number of FEM manufacturers to 4. Usually FEM parameters from ini file are read from nvs file and passed to firmware using TEST_CMD_INI_FILE_RADIO_PARAM. Still, because the nvs file has only place for 2 FEMs, we need to pass the new FEM types information in one of the available entries. This is done by mapping new fem types 2,3 to entry 0. This solution works for manual FEM selection. AutoDetect-FEM still support only fem types 0 and 1. Signed-off-by: Yair Shapira <yair.shapira@ti.com> Signed-off-by: Luciano Coelho <coelho@ti.com>
2012-06-08wlcore/wl18xx/wl12xx: use u8 instead of bool for host_fast_wakeup_supportLuciano Coelho
The conf structure is going to be exported to a file, so we should use only well defined types. bool is not well defined and may vary from platform to platform, so change the host_fast_wakeup_support type to u8 instead. Signed-off-by: Luciano Coelho <coelho@ti.com>

2012-06-07wl18xx: pad only last frame in aggregration buffer for PG2Ido Reis
In PG2 only the last frame in the aggregate buffer should be aligned to the sdio block size. This frame's header msb should be set to 0, while in all the previous frames in the aggregation buffer, this bit should be set to 1. [Add a HW op for setting the frame ctrl bit only for 18xx.

2012-06-07wl18xx: PG2.0 HW Watch dog interrupt supportIdo Reis
In PG2, the HW watchdog interrupt occupies bit0 of the event vector, and the SW watchdog is relocated to bit9. We perform the relocation globally, as there's only one watchdog bit on previous platforms (bit0). [Only mask in the new bit9 for platforms supporting it.

2012-06-06wl12xx/wl18xx: add erp protection IE to the beacon filterEliad Peller

2012-06-06wlcore/wl12xx/wl18xx: implement op_set_key per HW archArik Nemtsov
The 12xx set_key just calls the common wlcore_set_key function, in order to program the keys into the FW. The 18xx variant changes the spare block count when a GEM or TKIP key is set. Also modify the get_spare_blocks HW op for 18xx to return the correct numbers of spare blocks, according to what is currently set in FW.

2012-06-06wlcore/wl12xx/wl18xx: handle spare blocks spacial cases per archArik Nemtsov
Add a HW op for getting spare blocks. 12xx cards require 2 spare blocks for GEM encrypted SKBs, regardless of VIFs or keys programmed into the FW. 18xx cards require 2 spare blocks when there are any connected TKIP or GEM VIFs. For now always return 2 spare blocks, as this works with all networks. The special case TKIP/GEM functionality is added at a later patch.

2012-06-05wl12xx: set the irq polarity before loading the fwYoni Divinsky
The polarity should be set before the firmware is loaded since the firmware touches the same register.

2012-06-05wlcore/wl12xx/wl18xx: don't use TX align quirk for wl127xLuciano Coelho
Commit 4afc37 (wlcore: reorder identify_chip and get_hw_info) broke support for wl127x chips. When we moved the identify_chip operation to an earlier stage (ie. to the probe function), we broke wl127x support because during HW init we would set the WLCORE_QUIRK_TX_BLOCKSIZE_ALIGN. To avoid this, set this quirk in the identify_chip operations and only force it to be unset if the bus module doesn't support it. We were doing the opposite and setting the flag if the bus module supports it. Signed-off-by: Luciano Coelho <coelho@ti.com>
2012-06-05wlcore/wl12xx/wl18xx: move lower driver debugfs to a subdirLuciano Coelho
Instead of adding more files from the lower drivers into the same directory in debugfs as wlcore, we now add a subdirectory for the lower driver. This makes things a bit easier, because we can quickly see where the debugfs entry is implemented and what is specific to the lower driver.

2012-06-05wlcore/wl12xx/18xx: split fw_status struct into twoArik Nemtsov
The number of RX packet descriptors may vary from chip to chip and in different firmware versions. Unfortunately, the array that contains the actual descriptors is in the middle of the fw_status structure. To manage this, we split the struct into two so we can calculate the offset of what comes after the array and access the last elements more easily.

2012-04-12wlcore/wl12xx: use a single memory config and reset if using wl127xLuciano Coelho
Instead of having two memory configuration sets, one for wl127x and one for wl128x, we can use only one which should be correctly set by the lower driver.

2012-04-12wlcore/wl12xx: turn no-Tx-align quirk into Tx-alignArik Nemtsov
Inverting the quirk flag to indicate Tx-alignment. This aligns it with the similar Rx-side quirk. The call to wl1271_set_block_size() decides whether SDIO block size alignment can be used or not. In case we're using SPI, we can't use the block size alignment, so the function returns false. So we set the quirk when wl1271_set_block_size() returns true and let the wl12xx lower driver unset the bit for wl127x (since it doesn't support this quirk).

2012-04-12wlcore/wl12xx: split Tx completion to immediate/delayedArik Nemtsov
One chip family employs immediate Tx completion, where knowledge of completed packets is given as part of the FW status. Another is only notified of Tx completion via the FW status, and has to read the completion status of the packets from a different location.

2012-04-12wlcore/wl12xx: add prepare_read hw op for Rx dataLuciano Coelho
The only difference in the read_data operations is that some chips need to prepare the data to be read before reading. So instead of having a mandatory read_data operation, we now have an option prepare_data operation that only needs to be implemented for chips that require it.

An aligned data buffer is such where the Ethernet portion of the packet starts on a 4-byte boundary. Some chip families support padding the Rx data buffer to achieve such alignment, others rely on the host to perform it. Implement the HW op for getting alignment state in wl12xx.
