2021-05-19mlxsw: spectrum_router: Replace if statement with a switch statementIdo Schimmel1-31/+38
The code was written when only two multipath hash policies were present, so the if statement was sufficient. The next patch and future patches are going to add support for more policies, so move to a switch statement.

2021-05-19nfc: s3fwrn5: i2c: Enable optional clock from device treeStephan Gerhold1-2/+28
S3FWRN5 depends on a clock input ("XI" pin) to function properly. Depending on the hardware configuration this could be an always-on oscillator or some external clock that must be explicitly enabled. So far we assumed that the clock is always-on. Make the driver request an (optional) clock from the device tree and make sure the clock is running before starting S3FWRN5. Note: S3FWRN5 asserts "GPIO2" whenever it needs the clock input to function correctly. On some hardware configurations, GPIO2 is connected directly to an input pin of the external clock provider (e.g. the main PMIC of the SoC). In that case, it can automatically AND the clock enable bit and clock request from S3FWRN5 so that the clock is actually only enabled when needed. It is also conceivable that on some other hardware configuration S3FWRN5's GPIO2 might be connected as a regular GPIO input of the SoC. In that case, follow-up patches could extend the driver to request the GPIO, set up an interrupt and only enable the clock when requested by S3FWRN5.

Initial support for the Mellanox SwitchX-2 ASIC was added in July 2015. Since then all development efforts shifted towards the Mellanox Spectrum ASICs and development of this driver stopped beside trivial fixes and refactoring. Therefore, the driver does not support any switch offloads and simply traps all traffic to the CPU, rendering it irrelevant for deployment. In addition, support for this ASIC was dropped by Mellanox a few years ago. Given the driver is not used by any users and that there is no intention of investing in its development, remove it from the kernel.

2021-05-18mlxsw: core: Avoid unnecessary EMAD buffer copyIdo Schimmel1-1/+1
mlxsw_emad_transmit() takes care of sending EMAD transactions to the device. Since these transactions can time out, the driver performs up to 5 retransmissions, each time copying the skb with the original request. The data of the skb does not change throughout the process, so there is no need to copy it each time. Instead, only the skb itself can be copied. Therefore, use skb_clone() instead of skb_copy(). This reduces the latency of the function by about 16%. Signed-off-by: Ido Schimmel <idosch@nvidia.com> Signed-off-by: David S. Miller <davem@davemloft.net>
