* mwifiex: get_channel from firmwareGanapathi Bhat2018-03-131-0/+22
| | | | | | | | | | | | | At present driver gets chan_type by referring to IEEE80211_HT_PARAM_CHA_SEC_OFFSET, in ASSOC response. Sometimes AP shows IEEE80211_HT_PARAM_CHA_SEC_OFFSET as above/below in assoc response, even if the association is done on HT20 channel only. So, it will be accurate to get econdary channel offset from firmware.

* mwifiex: debugfs: trigger device dump for usb interfaceXinming Hu2018-01-081-0/+4
| | | | | | | | | | | | | | | | This patch extend device_dump debugfs function to make it works for usb interface. For command timeouts, USB firmware will automatically emit firmware dump events, so we don't implement device_dump(). For user-initiated dumps, we trigger it by issue firmware dump event command to firmware, as there is no command response, do not start 10s timer.

* mwifiex: usb: transmit aggregation packetsXinming Hu2017-05-311-0/+18
| | | | | | | | | | | | | | | | | | Instead of using 4KB packet buffer for data transfer, new chipset have more device memory. This patch try to aggregation packets in an 16KB buffer. In this way, totally usb transaction cost will be reduced. Thoughput test on usb 2.0 show both TCP TX and UPD TX promote ~40M, from ~240M to ~280M. This feature is default disabled, and can be enabled by module parameter, like: insmod mwifiex.ko aggr_ctrl=1 Signed-off-by: Xinming Hu <huxm@marvell.com> Signed-off-by: Cathy Luo <cluo@marvell.com> Signed-off-by: Ganapathi Bhat <gbhat@marvell.com> Signed-off-by: Kalle Valo <kvalo@codeaurora.org>

* mwifiex: fix for unaligned readsDevidas Puranik2017-03-201-9/+10
| | | | | | | | | | Using the accessor function e.g. get_unaligned_le32 instead of le32_to_cpu to avoid the unaligned access.

* mwifiex: Use accessors routines for unaligned valuesDaniel Mentz2017-03-201-13/+17
| | | | | | | | | | | | | Synopsys' ARCompact architecture does not support loading from or storing values to unaligned memory locations. We saw a series of misaligned access exceptions on ARC. To work around this issue, we bulk replaced le16_to_cpu and le32_to_cpu with get_unaligned_le16 and get_unaligned_le32, respectively. We also added le16_unaligned_add_cpu which is similar to le16_add_cpu but works with unaligned values.

| | | | | | | | | | | | | | Introduce function mwifiex_probe_of() to parse common properties. Interface drivers get to decide whether or not the device tree node was a valid one (depending on the compatible property), Lets fill "adapter->dt_node" in mwifiex_add_card().

* mwifiex: Reduce endian conversion for REG Host CommandsPrasun Maiti2016-07-181-16/+12
| | | | | | | | | | | | | | | For multiple REG Host Commands (e.g HostCmd_CMD_802_11_EEPROM_ACCESS, HostCmd_CMD_MAC_REG_ACCESS etc.) "cpu_to_leX"-converted values are saved to driver. So, "leX_to_cpu" conversion is required too many times afterwards in driver. This patch reduces the endian: conversion without saving "cpu_to_leX" converted values in driver. This will convert endianness in prepare command and command response path.

* mwifiex: add get_antenna support for cfg80211Shengzhen Li2016-07-051-16/+34
| | | | | | | | | | | | | | | | | | | | | | | | Since commit de3bb771f471 ("cfg80211: add more warnings for inconsistent ops") the wireless core warns if a driver implements a cfg80211 callback but doesn't implements the inverse operation. The mwifiex driver defines a .set_antenna handler but not a .get_antenna so this not only makes the core to print a warning when creating a new wiphy but also the antenna isn't reported to user-space apps such as iw. This patch queries the antenna to the firmware so is properly reported to user-space. With this patch, the wireless core does not warn anymore and: $ iw phy phy0 info | grep Antennas Available Antennas: TX 0x3 RX 0x3 Configured Antennas: TX 0x3 RX 0x3 Signed-off-by: Shengzhen Li <szli@marvell.com> Signed-off-by: Amitkumar Karwar <akarwar@marvell.com> [javier: expand the commit message] Signed-off-by: Javier Martinez Canillas <javier@osg.samsung.com> Tested-by: Enric Balletbo i Serra <enric.balletbo@collabora.com> Signed-off-by: Kalle Valo <kvalo@codeaurora.org>
