qca_7k: Replace BSD boilerplate with SPDX

2024-01-31T13:38:51Z

According to MODULE_LICENSE the driver is under a dual license. So replace the BSD license text with the proper SPDX tag. Signed-off-by: Stefan Wahren Signed-off-by: Stefan Wahren Reviewed-by: Jacob Keller Signed-off-by: David S. Miller

net: qca_spi: Introduce write register verification

2018-09-24T19:26:06Z

The SPI protocol for the QCA7000 doesn't have any fault detection. In order to increase the drivers reliability in noisy environments, we could implement a write verification inspired by the enc28j60. This should avoid situations were the driver wrongly assumes the receive interrupt is enabled and miss all incoming packets. This function is disabled per default and can be controlled via module parameter wr_verify. Signed-off-by: Michael Heimpold Signed-off-by: Stefan Wahren Signed-off-by: David S. Miller

net: qca_spi: Fix race condition in spi transfers

2018-09-05T15:09:35Z

With performance optimization the spi transfer and messages of basic register operations like qcaspi_read_register moved into the private driver structure. But they weren't protected against mutual access (e.g. between driver kthread and ethtool). So dumping the QCA7000 registers via ethtool during network traffic could make spi_sync hang forever, because the completion in spi_message is overwritten. So revert the optimization completely.

net: qualcomm: move qcaspi_tx_cmd to qca_spi.c

2017-05-30T17:57:29Z

The function qcaspi_tx_cmd() is only called from qca_spi.c. So we better move it there. Signed-off-by: Stefan Wahren Signed-off-by: David S. Miller

net: qualcomm: qca_7k: clean up header includes

2017-05-30T17:57:27Z

Currently the includes doesn't reflect the dependencies. So fix this up by removing all unnecessary entries and add the necessary ones explicit. Signed-off-by: Stefan Wahren Signed-off-by: David S. Miller
