2021-03-30mlxsw: spectrum_router: Only perform atomic nexthop bucket replacement when ↵Ido Schimmel
requested When cleared, the 'force' parameter in nexthop bucket replacement notifications indicates that a driver should try to perform an atomic replacement. Meaning, only update the contents of the bucket if it is inactive. Since mlxsw only queries buckets' activity once every second, there is no point in trying an atomic replacement if the idle timer interval is smaller than 1 second. Currently, mlxsw ignores the original value of 'force' and will always try an atomic replacement if the idle timer is not smaller than 1 second. Fix this by taking the original value of 'force' into account and never promoting a non-atomic replacement to an atomic one.

Michal Simek's patch for the xilinx driver add dev_err_probe() support. Arnd Bergmann's patch for the ucan driver fixes a compiler warning. Stephane Grosjean provides 3 patches for the peak USB drivers, which add ethtool set_phys_id and CAN one-shot mode. Xulin Sun's patch removes a not needed return check in the m-can driver. Torin Cooper-Bennun provides 3 patches for the m-can driver that add rx-offload support to ensure that skbs are sent from softirq context. Wan Jiabing's patch for the tcan4x5x driver removes a duplicate include. The next 6 patches are by me and target the mcp251xfd driver. They add devcoredump support, simplify the UINC handling, and add HW timestamp support. The remaining 12 patches target the c_can driver.

2021-03-30can: c_can: add support to 64 message objectsDario Binacchi
D_CAN controller supports 16, 32, 64 or 128 message objects, comparing to 32 on C_CAN. AM335x/AM437x Sitara processors and DRA7 SOC all instantiate a D_CAN controller with 64 message objects, as described in the "DCAN features" subsection of the CAN chapter of their technical reference manuals. The driver policy has been kept unchanged, and as in the previous version, the first half of the message objects is used for reception and the second for transmission. The I/O load is increased only in the case of 64 message objects, keeping it unchanged in the case of 32. Two 32-bit read accesses are in fact required, which however remained at 16-bit for configurations with 32 message objects.

2021-03-30can: c_can: prepare to up the message objects numberDario Binacchi
As pointed by commit c0a9f4d396c9 ("can: c_can: Reduce register access") the "driver casts the 16 message objects in stone, which is completely braindead as contemporary hardware has up to 128 message objects". The patch prepares the module to extend the number of message objects beyond the 32 currently managed. This was achieved by transforming the constants used to manage RX/TX messages into variables without changing the driver policy.

All transfers but the last need to have the cs_change set to 1. In the original patches the array of prepared transfers is send from the beginning with the length depending on the number of read TEF/RX objects. The cs_change of the last transfer is temporarily set to 0 during send. This patch removes the modification of cs_change by preparing the last transfer with cs_change to 0 and all other to 1. When sending the SPI message the driver now starts with an offset into the array, so that it always ends on the last entry in the array, which has the cs_change set to 0.
