2012-06-08wl18xx: align wl18xx_conf_phy with FW variant and remove itArik Nemtsov3-110/+36
wl18xx_conf_phy represents part of the FW native wl18xx_mac_and_phy_params structure. Remove it and replace the phy part of the wl18xx conf with the FW bound structure. This allows us to set/override all members. Increment the wlconf version to ensure compatibility with the new structure Signed-off-by: Arik Nemtsov <arik@wizery.com> Signed-off-by: Luciano Coelho <coelho@ti.com>
2012-06-08wl18xx: update fw statisticsIdo Reis2-24/+65
Aligned to the struct in FW 8.2.0.0.91 and updated the debugfs entries accordingly. Signed-off-by: Ido Reis <idor@ti.com> Signed-off-by: Luciano Coelho <coelho@ti.com>
2012-06-08wl18xx: allow FW-log by default for PG2.0Arik Nemtsov1-1/+0
This is supported by new FW versions (.88+). Signed-off-by: Arik Nemtsov <arik@wizery.com> Signed-off-by: Luciano Coelho <coelho@ti.com>
2012-06-08wl18xx: read configuration structure from a binary fileLuciano Coelho1-5/+63
Instead of using the hardcoded configuration structure, try to read it from a "firmware" file called wl18xx-conf.bin. If the file doesn't exist, fall back to the hardcoded version. If the file exists but is illegal, bail out. Signed-off-by: Luciano Coelho <coelho@ti.com>
2012-06-08wlcore/wl18xx: export conf struct in a debugfs fileLuciano Coelho2-0/+50
Add conf file header structure, magic and version values and export the entire conf struct in debugfs. Signed-off-by: Luciano Coelho <coelho@ti.com>
2012-06-08wlcore/wl18xx: the conf structs must be packed so they can be exportedLuciano Coelho1-2/+2
Since we are now going to export the conf structure and read it from a file, it should be packed to avoid surprises with padding bytes. Signed-off-by: Luciano Coelho <coelho@ti.com>
2012-06-08wlcore/wl18xx/wl12xx: use u8 instead of bool for host_fast_wakeup_supportLuciano Coelho1-1/+1
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>
2012-06-08wl18xx: add support to clear FW statisticsLuciano Coelho3-0/+63
This patch calls ACX_CLEAR_STATISTICS to clear the firmware statistics. The trigger is a new debugfs file called clear_fw_statistics in the fw_stats directory. Signed-off-by: Luciano Coelho <coelho@ti.com>
2012-06-07wl18xx: pad only last frame in aggregration buffer for PG2Ido Reis2-2/+31
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 Reis2-2/+32
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. This avoids spurious events on other platforms - Arik] Signed-off-by: Orit Brayer <orit@ti.com> Signed-off-by: Ido Reis <idor@ti.com> Signed-off-by: Arik Nemtsov <arik@wizery.com> Signed-off-by: Luciano Coelho <coelho@ti.com>
2012-06-07wl18xx: FW/PHY arguments added for PG2Ido Reis3-1/+28
PG2 requires 4 new parameters that to be passed to the PHY. Use the actual PHY initialization struct size for the mem size of the PHY_INIT section, to account for additions in params. [Make sure PG1 still gets the original struct - Arik] Signed-off-by: Ido Reis <idor@ti.com> Signed-off-by: Arik Nemtsov <arik@wizery.com> Signed-off-by: Luciano Coelho <coelho@ti.com>

2012-06-06wl12xx/wl18xx: add erp protection IE to the beacon filterEliad Peller1-1/+5
We have to reconfigure the fw when erp protection should be enabled/disabled. Pass beacons containing changes in the ERP protection IE, so we could analyze them. Signed-off-by: Eliad Peller <eliad@wizery.com> Signed-off-by: Luciano Coelho <coelho@ti.com>
2012-06-06wlcore/wl12xx/wl18xx: implement op_set_key per HW archArik Nemtsov3-12/+91
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 Nemtsov2-4/+10
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.

2012-06-06wlcore/wl12xx/wl18xx: introduce quirk to remove TKIP header spaceArik Nemtsov1-1/+2
18xx chips do not require extra space in the TKIP header. Introduce a new HW quirk to allow us to make this feature arch-specific. 12xx chip will now have this quirk. Signed-off-by: Arik Nemtsov <arik@wizery.com> Signed-off-by: Luciano Coelho <coelho@ti.com>

2012-06-05wlcore: fix dynamic_ps_timeout time regressionArik Nemtsov1-1/+1
In patch d7b63b9fc7ee73e75a4c7fdb899 we have raised the dynamic PS timeout to 200ms to improve user experience. Re-apply the change, since it was reverted in the wlcore split. Signed-off-by: Arik Nemtsov <arik@wizery.com> Signed-off-by: Luciano Coelho <coelho@ti.com>
2012-06-05wlcore: fix sparse warnings related to static functionsArik Nemtsov1-1/+1

2012-06-05wlcore/wl12xx/wl18xx: don't use TX align quirk for wl127xLuciano Coelho1-2/+3
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>
2012-06-05wl18xx: change default tcp_checksum to falseAssaf Azulay1-2/+2
as tcp check sum is going to be removed from firmware, and as there is a problem with getting dns in security when checksum is enabled, it was decided to disable it by default. for none security modes it can be enabled by module paramenter.

2012-06-05wlcore/wl12xx/wl18xx: move lower driver debugfs to a subdirLuciano Coelho2-8/+9
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.

2012-06-05wl18xx: export pwr_limit_reference_11_abg value as a module parameterLuciano Coelho1-0/+12
Yet another temporary module parameter requested by the firmware team. This will be replaced by the conf binary. Signed-off-by: Luciano Coelho <coelho@ti.com> Signed-off-by: Arik Nemtsov <arik@wizery.com>
2012-06-05wl18xx: export low/high band component values as module paramsLuciano Coelho1-0/+46
We use hardcoded values for the different board types. In some cases we may need to override the defaults, so export the values as module params. If not defined, the defaults for the specified board type will be used. Signed-off-by: Luciano Coelho <coelho@ti.com> Signed-off-by: Arik Nemtsov <arik@wizery.com>
2012-06-05wl18xx: add power limit reference value to mac_and_phy settingsLuciano Coelho2-0/+4
With more recent PHY firmware versions (>8.1.0.0.116), we need to use the correct value for the pwr_limit_reference_11_abg parameter when setting the mac_and_phy options. For now we use a hardcoded 0xc8 as the value. This will be moved to the configuration binary when it gets implemented.

2012-06-05wl18xx: add module parameter to force SISO 20MHzLuciano Coelho1-6/+32
In some cases it may be useful to force narrow-band SISO channels. Add a new value to the ht_mode module parameter to force the device to operate in SISO 20MHz. Signed-off-by: Luciano Coelho <coelho@ti.com> Signed-off-by: Arik Nemtsov <arik@wizery.com>
2012-06-05wl18xx: don't use MIMO when ht_mode is set to wideLuciano Coelho1-5/+8
If the wl18xx module is loaded with ht_mode=wide (the default), we shouldn't use MIMO rates when the channel type is not HT40. Fix this by checking the ht_mode before deciding which rates to used. Additionally, set the ht_mode parameter explicitly to "wide" as the default. Signed-off-by: Luciano Coelho <coelho@ti.com> Signed-off-by: Arik Nemtsov <arik@wizery.com>
2012-06-05wl18xx: print the PHY firmware version from the private static dataLuciano Coelho2-0/+19

2012-06-05wl18xx: change low_band_component_type value for COM8Luciano Coelho1-0/+2
Like HDK, COM8 uses 0x06 for the low_band_component_type as well. Hardcode the value for COM8 until this configuration can be done in the external configuration binary (to be implemented). Signed-off-by: Luciano Coelho <coelho@ti.com> Signed-off-by: Arik Nemtsov <arik@wizery.com>
2012-06-05wl18xx: changed default board_type to HDKLuciano Coelho1-7/+4

2012-06-05wl18xx: copy the default configuration before checking the board_typeLuciano Coelho1-2/+2
We were changing the low_band_component_type in the private configuration structure before copying the default values to it, so the change was overwritten and only took effect after HW recovery.

2012-06-05wl18xx: add a module parameter to control 11a supportLuciano Coelho1-0/+6
In wl18xx we don't have an NVS yet, so we need to control whether 11a is supported with a module parameter for now. 11a support is enabled by default and can be changed by setting enable_11a to false when loading the module.

2012-06-05wlcore/wl12xx/18xx: split fw_status struct into twoArik Nemtsov2-1/+2
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.
