wilc1000: add valid vmm_entry check before fetching from TX queue

2022-05-11T05:25:34Z

'vmm_table' array contains the size of data buffer length including host header length. In 'vmm_table' array, the Zero value means the end of vmm_entries that needs to transfer to firmware which is calculated based on VMM free size in firmware. Use 'vmm_table' valid entry check before fetching the entry from TX queue to only copy valid number of entries to avoid possible NULL pointer exception observed sometimes during large file transfers.

wilc1000: fix crash observed in AP mode with cfg80211_register_netdevice()

2022-05-11T05:25:33Z

Monitor(mon.) interface is used for handling the AP mode and 'ieee80211_ptr' reference is not getting set for it. Like earlier implementation, use register_netdevice() instead of cfg80211_register_netdevice() which expects valid 'ieee80211_ptr' reference to avoid the possible crash.

wilc1000: use fixed function base register value to access SDIO_FBR_ENABLE_CSA

2022-05-11T05:25:33Z

The function number was not correct(reset to 0) when host resumes from suspend state. Use hardcoded value in function base information register(FBR base address) to re-initialize correctly on host resume.

spi: make remove callback a void function

2022-02-09T13:00:45Z

The value returned by an spi driver's remove function is mostly ignored. (Only an error message is printed if the value is non-zero that the error is ignored.) So change the prototype of the remove function to return no value. This way driver authors are not tempted to assume that passing an error to the upper layer is a good idea. All drivers are adapted accordingly. There is no intended change of behaviour, all callbacks were prepared to return 0 before.

wilc1000: Add reset/enable GPIO support to SPI driver

2021-12-22T17:51:18Z

For the SDIO driver, the RESET/ENABLE pins of WILC1000 are controlled through the SDIO power sequence driver. This commit adds analogous support for the SPI driver. Specifically, during initialization, the chip will be ENABLEd and taken out of RESET and during deinitialization, the chip will be placed back into RESET and disabled (both to reduce power consumption and to ensure the WiFi radio is off). Both RESET and ENABLE GPIOs are optional. However, if the ENABLE GPIO is specified, then the RESET GPIO should normally also be specified as otherwise there is no way to ensure proper timing of the ENABLE/RESET sequence.
