2020-12-10wilc1000: changes for SPI communication stall issue found with IperfAjay Singh
Added retry mechanism to ensure VMM enable bit is set during the block transfer of data between host and WILC FW. Signed-off-by: Ajay Singh <ajay.kathat@microchip.com> Signed-off-by: Kalle Valo <kvalo@codeaurora.org> Link: https://lore.kernel.org/r/20201208103739.28597-1-ajay.kathat@microchip.com
2020-12-07wilc1000: remove redundant assignment to pointer vifColin Ian King
The assignment to pointer vif is redundant as the assigned value is never read, hence it can be removed.

2020-12-02wilc1000: added queue support for WMMAjay Singh
Added multiple queues[BK,BE,VI,VO] to handle different priority data packets. Before adding a packet to the queue, checked its priority from the header, and then add to the suitable queue. The limit for each queue is maintained separately. Also while passing the packets to the firmware via VMM take care to select data packets based on priority and available space.

2020-09-21net: wilc1000: clean up resource in error path of init mon interfaceHuang Guobin
The wilc_wfi_init_mon_int() forgets to clean up resource when register_netdevice() failed. Add the missed call to fix it. And the return value of netdev_priv can't be NULL, so remove the unnecessary error handling.

2020-07-14wilc1000: let wilc_mac_xmit() return NETDEV_TX_OKLuc Van Oostenryck
The method ndo_start_xmit() is defined as returning an 'netdev_tx_t', which is a typedef for an enum type defining 'NETDEV_TX_OK' but this driver returns '0' instead of 'NETDEV_TX_OK'. Fix this by returning 'NETDEV_TX_OK' instead of '0'.

2020-06-26wilc1000: move wilc driver out of stagingAjay Singh
WILC1000 is an IEEE 802.11 b/g/n IoT link controller module. The WILC1000 connects to Microchip AVR/SMART MCUs, SMART MPUs, and other processors with minimal resource requirements with a simple SPI/SDIO-to-Wi-Fi interface. WILC1000 driver has been part of staging for few years. With contributions from the community, it has improved significantly. Full driver review has helped in achieving the current state. The details for those reviews are captured in 1 & 2.
