qtnfmac: fix error handling in control path

2018-11-06T16:57:37Z

This patch fixes the following warnings: - smatch drivers/net/wireless/quantenna/qtnfmac/commands.c:132 qtnf_cmd_send_with_reply() warn: variable dereferenced before check 'resp' (see line 117) drivers/net/wireless/quantenna/qtnfmac/commands.c:716 qtnf_cmd_get_sta_info() error: uninitialized symbol 'var_resp_len'. drivers/net/wireless/quantenna/qtnfmac/commands.c:1668 qtnf_cmd_get_mac_info() error: uninitialized symbol 'var_data_len'. drivers/net/wireless/quantenna/qtnfmac/commands.c:1697 qtnf_cmd_get_hw_info() error: uninitialized symbol 'info_len'. drivers/net/wireless/quantenna/qtnfmac/commands.c:1753 qtnf_cmd_band_info_get() error: uninitialized symbol 'info_len'. drivers/net/wireless/quantenna/qtnfmac/commands.c:1782 qtnf_cmd_send_get_phy_params() error: uninitialized symbol 'response_size'. drivers/net/wireless/quantenna/qtnfmac/commands.c:2438 qtnf_cmd_get_chan_stats() error: uninitialized symbol 'var_data_len'. - gcc-8.2.1 drivers/net/wireless/quantenna/qtnfmac/commands.c: In function 'qtnf_cmd_send_with_reply': drivers/net/wireless/quantenna/qtnfmac/commands.c:133:54: error: 'resp' may be used uninitialized in this function [-Werror=maybe-uninitialized] Reported-by: Dan Carpenter Reported-by: Arnd Bergmann Signed-off-by: Sergey Matyukevich Signed-off-by: Kalle Valo

qtnfmac: add support for Topaz chipsets

2018-11-06T16:53:50Z

This patch adds support for QSR1000/QSR2000 family of chipsets to qtnfmac_pcie platform driver. QSR1000/QSR2000 (aka Topaz) is a family of 80MHz, 11ac Wave2, 4x4/2x4/2x2 chips, including single and dual band devices. Depending on specific chip model and firmware in use, either STA or both STA and AP modes are supported. Patch adds Topaz support to qtnfmac_pcie driver. Proper platform bus will be selected on probing based on chip ID. Signed-off-by: Igor Mitsyanko Signed-off-by: Sergey Matyukevich Signed-off-by: Andrey Shevchenko Signed-off-by: Kalle Valo

qtnfmac_pcie: use single PCIe driver for all platforms

2018-11-06T16:53:49Z

Single PCIe driver can identify hardware type by reading CHIP ID at probe time and invoking a correct initialization sequence. Signed-off-by: Igor Mitsyanko Signed-off-by: Kalle Valo

qtnfmac_pcie: cleanup Pearl platform headers

2018-10-13T17:04:48Z

Remove redundant information from Pearl platform headers. Signed-off-by: Sergey Matyukevich Signed-off-by: Kalle Valo

qtnfmac: use SPDX identifier for pcie bus layer files

2018-10-13T17:04:47Z

Change pcie bus layer licensing information to SPDX format. Signed-off-by: Sergey Matyukevich Signed-off-by: Kalle Valo

qtnfmac: use 'help' in Kconfig

2018-10-13T17:04:45Z

Fix checkpatch warning: use preferred 'help' option in Kconfig. Signed-off-by: Sergey Matyukevich Signed-off-by: Kalle Valo

qtnfmac: implement dump_station support for STA mode

2018-10-05T11:01:44Z

Current implementation of dump_station cfg80211 callback supports AP mode only. Add support for STA mode as well: by default in STA mode this callback is supposed to return AP on managed interface. Signed-off-by: Sergey Matyukevich Signed-off-by: Kalle Valo

qtnfmac: drop redundant data copy in control path

2018-10-05T11:01:41Z

Command responses and events from the firmware are copied twice in control path: at first in shm core (qtnf_shm_handle_new_data) and then in pcie bus drivers (qtnf_pcie_control_rx_callback). There is no need to copy this data twice, it can be done only once in rx callbacks. Signed-off-by: Sergey Matyukevich Signed-off-by: Kalle Valo

qtnfmac: add support for scan dwell time configuration

2018-10-05T11:01:37Z

Firmware supports scan dwell time tuning for various types of scans. Enable support for this feature: - advertise capability to configure channel dwell time to host - pass scan dwell parameters to wireless card in scan request Signed-off-by: Sergey Matyukevich Signed-off-by: Kalle Valo

qtnfmac: add support for scan flush

2018-10-05T11:01:33Z

Notify firmware to flush cache before scanning when needed. Signed-off-by: Sergey Matyukevich Signed-off-by: Kalle Valo
