2019-11-05staging: wilc1000: remove 'wilc_' prefix from filenamesAjay Singh1-955/+0
Remove 'wilc_' prefix from filenames, the driver is already present inside the 'wilc1000' directory so no need to add 'wilc_' in filenames.

2019-10-24staging: wilc1000: handle mgmt frames for both interfaces during concurrent modeAjay Singh1-7/+4
During concurrent mode(AP/STA + P2P), pass the mgmt frames received from firmware to appropriate interface. Iterate the complete interface list to pass frames on the interface which has registered to receive mgmt frame. Added extra time for 'remain_on_ch' timer to ensure that timeout for uncanceled remain_on_channel is not triggered & 'p2p_listen_state' is not cleared before passing the mgmt frames to p2p interface.

2019-09-30staging: wilc1000: use RCU list to maintain vif interfaces listAjay Singh1-39/+78
Make use of RCU list to maintain virtual interfaces instead of an array. The update operation on 'vif' list is less compare to the read operations. Mostly the 'vif' list elements are accessed for the read operation, so RCU list is more suited for this requirement. The shifting of interface index id's during the delete interface is not required. As the firmware only supports 2 interfaces so make use of available free slot index id during add interface.

2019-09-30staging: wilc1000: move wlan_deinit_locks() in wilc_netdev_cleanup()Ajay Singh1-13/+1
Move deinitialization of lock during the module remove and the initialization of lock wilc_cfg80211_init(). This to ensure locks are available during module load and gets free during unload.

2019-09-12staging: wilc1000: avoid twice IRQ handler execution for each single interruptAjay Singh1-1/+1
The IRQ handler(isr_bh_routine()) was called twice for each interrupt from firmware. The data was read completely during the first call and the second call was doing nothing. Now changed the IRQ flag from ‘level’ to ‘edge’ trigger i.e IRQF_TRIGGER_LOW to IRQF_TRIGGER_FALLING to avoid extra interrupt trigger.

2019-08-12staging: wilc1000: Don't reset WILC CPU disgracefullyAdham Abozaeid1-2/+2
Send abort request to WILC from wilc_wlan_stop instead of resetting the CPU. The abort request was being sent from wilc_wlan_cleanup after the CPU was reset which wasn't the correct order. The abort request handler in the chip will take care of resetting the CPU.

2019-08-02staging: wilc1000: merge drv_handle and operation_mode widsAdham Abozaeid1-4/+2
wilc_set_wfi_drv_handler and wilc_set_operation_mode sends the same parameters to the FW, so it's better to combine them together. Kept wilc_set_wfi_drv_handler implementation since it sends all the required parameters, and renamed it to wilc_set_operation_mode to be more descriptive.

2019-07-22staging: wilc1000: Replace function wilc_wlan_cfg_get_val()Nishka Dasgupta1-0/+1
Include wilc_wlan_cfg.h in wilc_netdev.c to enable it to call functions in wilc_wlan_cfg.c. Remove function wilc_wlan_cfg_get_val as all it does is call wilc_wlan_cfg_get_wid_value in file wilc_wlan_cfg.c. Rename function wilc_wlan_cfg_get_wid_value to wilc_wlan_cfg_get_val to maintain compatibility with call sites (including in wilc_netdev.c). Issue found with Coccinelle.

2019-07-01staging: wilc1000: added support to dynamically add/remove interfacesAjay Singh1-171/+98
Removed the use of two hardcoded interfaces and added support to add/remove the network interfaces dynamically. Now the driver will have single default interface with name 'wlan0' and later other interface can be added from user space application e.g using 'iw add' command. Also taken care to maintain 'wilc_vif' as part of 'net_device' private data and 'wilc' struct as 'wiphy' private data.
