wilc1000: Convert static "chipid" variable to device-local variable

2021-12-22T17:50:50Z

Move "chipid" variable into the per-driver structure so the code doesn't break if more than one wilc1000 module is present. Signed-off-by: David Mosberger-Tang Signed-off-by: Kalle Valo Link: https://lore.kernel.org/r/20211221210538.4011227-1-davidm@egauge.net

wilc1000: Improve WILC TX performance when power_save is off

2021-12-16T08:30:21Z

The wakeup and sleep commands need to be sent to the WILC chip only when it is in power save mode (PSM, as controlled by "iw dev wlan0 set power_save on/off"). The commands are relatively costly, so it pays to skip them when possible. iperf3 without this patch (no significant different with PSM on/off): TX 0.00-120.01 sec 140 MBytes 9.82 Mbits/sec RX 0.00-120.69 sec 283 MBytes 19.6 Mbits/sec with this patch applied: PSM off (TX is 46% improved, RX slightly improved; may not be significant): TX 0.00-120.00 sec 206 MBytes 14.4 Mbits/sec RX 0.00-120.48 sec 322 MBytes 22.4 Mbits/sec PSM on (no significant change): TX 0.00-120.00 sec 140 MBytes 9.78 Mbits/sec RX 0.00-120.08 sec 257 MBytes 18.0 Mbits/sec Signed-off-by: David Mosberger-Tang Signed-off-by: Kalle Valo Link: https://lore.kernel.org/r/20211210203016.3680425-2-davidm@egauge.net

wilc1000: use eth_hw_addr_set()

2021-10-20T09:39:46Z

Commit 406f42fa0d3c ("net-next: When a bond have a massive amount of VLANs...") introduced a rbtree for faster Ethernet address look up. To maintain netdev->dev_addr in this tree we need to make all the writes to it got through appropriate helpers.

wilc1000: configure registers to handle chip wakeup sequence

2021-09-21T15:08:15Z

Use the correct sequence to configure clockless registers for chip wake-up. The following sequence is expected from WILC chip for wakeup: - set wakeup bit in wakeup_reg register - after setting the wakeup bit, read back the clock status bit for wakeup complete. For SDIO/SPI modules, the wakeup sequence is the same except uses different register values so refactored the code to use common function for both SDIO/SPI bus.

wilc1000: move 'deinit_lock' lock init/destroy inside module probe

2021-09-21T15:08:14Z

Move initialization & deinitialization of 'deinit_lock' mutex lock inside wlan_init_locks() & wlan_deinit_locks() API's respectively alongside other locks. After the movement, the client count variable(client_count) which is used for lock init/deinit is removed.

wilc1000: added queue support for WMM

2020-12-02T19:38:12Z

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.

wilc1000: move wilc driver out of staging

2020-06-26T05:46:46Z

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.
