2022-01-07spi: don't include ptp_clock_kernel.h in spi.hJakub Kicinski
Commit b42faeee718c ("spi: Add a PTP system timestamp to the transfer structure") added an include of ptp_clock_kernel.h to spi.h for struct ptp_system_timestamp but a forward declaration is enough. Let's use that to limit the number of objects we have to rebuild every time we touch networking headers.

2022-01-07regmap: Call regmap_debugfs_exit() prior to _init()Fabio Estevam
Since commit cffa4b2122f5 ("regmap: debugfs: Fix a memory leak when calling regmap_attach_dev"), the following debugfs error is seen on i.MX boards: debugfs: Directory 'dummy-iomuxc-gpr@20e0000' with parent 'regmap' already present! In the attempt to fix the memory leak, the above commit added a NULL check for map->debugfs_name. For the first debufs entry, map->debugfs_name is NULL and then the new name is allocated via kasprintf(). For the second debugfs entry, map->debugfs_name() is no longer NULL, so it will keep using the old entry name and the duplicate name error is seen. Quoting Mark Brown: "That means that if the device gets freed we'll end up with the old debugfs file hanging around pointing at nothing. ... To be more explicit this means we need a call to regmap_debugfs_exit() which will clean up all the existing debugfs stuff before we loose references to it." Call regmap_debugfs_exit() prior to regmap_debugfs_init() to fix the problem. Tested on i.MX6Q and i.MX6SX boards.

2022-01-07i40e: Minimize amount of busy-waiting during AQ sendJedrzej Jagielski
The i40e_asq_send_command will now use a non blocking usleep_range if possible (non-atomic context), instead of busy-waiting udelay. The usleep_range function uses hrtimers to provide better performance and removes the negative impact of busy-waiting in time-critical environments. 1. Rename i40e_asq_send_command to i40e_asq_send_command_atomic and add 5th parameter to inform if called from an atomic context. Call inside usleep_range (if non-atomic) or udelay (if atomic). 2. Change i40e_asq_send_command to invoke i40e_asq_send_command_atomic(..., false). 3. Change two functions: - i40e_aq_set_vsi_uc_promisc_on_vlan - i40e_aq_set_vsi_mc_promisc_on_vlan to explicitly use i40e_asq_send_command_atomic(..., true) instead of i40e_asq_send_command, as they use spinlocks and do some work in an atomic context. All other calls to i40e_asq_send_command remain unchanged.

git://git.kernel.org/pub/scm/linux/kernel/git/saeed/linux Saeed Mahameed says: ==================== mlx5-updates-2022-01-06 1) Expose FEC per lane block counters via ethtool 2) Trivial fixes/updates/cleanup to mlx5e netdev driver 3) Fix htmldoc build warning 4) Spread mlx5 SFs (sub-functions) to all available CPU cores: Commits 1..5 Shay Drory Says: ================ Before this patchset, mlx5 subfunction shared the same IRQs (MSI-X) with their peers subfunctions, causing them to use same CPU cores. In large scale, this is very undesirable, SFs use small number of cpu cores and all of them will be packed on the same CPU cores, not utilizing all CPU cores in the system. In this patchset we want to achieve two things. a) Spread IRQs used by SFs to all cpu cores b) Pack less SFs in the same IRQ, will result in multiple IRQs per core. In this patchset, we spread SFs over all online cpus available to mlx5 irqs in Round-Robin manner. e.g.: Whenever a SF is created, pick the next CPU core with least number of SF IRQs bound to it, SFs will share IRQs on the same core until a certain limit, when such limit is reached, we request a new IRQ and add it to that CPU core IRQ pool, when out of IRQs, pick any IRQ with least number of SF users. This enhancement is done in order to achieve a better distribution of the SFs over all the available CPUs, which reduces application latency, as shown bellow.

This patch fixes the broken LED quirk for Intel legacy ROM devices. To fix the LED issue that doesn't turn off immediately, the host sends the SW RFKILL command while shutting down the interface and it puts the devices in SW RFKILL state. Once the device is in SW RFKILL state, it can only accept HCI_Reset to exit from the SW RFKILL state. This patch checks the quirk for broken LED and sends the HCI_Reset before sending the HCI_Intel_Read_Version command.

2022-01-06mlxsw: spectrum_acl_bloom_filter: Add support for Spectrum-4 calculationAmit Cohen
Spectrum-4 will calculate hash function for bloom filter differently from the existing ASICs. First, two hash functions will be used to calculate 16 bits result. The final result will be combination of the two results - 6 bits which are result of CRC-6 will be used as MSB and 10 bits which are result of CRC-10 will be used as LSB. Second, while in Spectrum{2,3}, there is a padding in each chunk, so the chunks use a sequence of whole bytes, in Spectrum-4 there is no padding, so each chunk use 20 bytes minus 2 bits, so it is necessary to align the chunks to be without holes. Add dedicated 'mlxsw_sp_acl_bf_ops' for Spectrum-4 and add the required tables for CRC calculations. All the details are documented as part of the code for future use.

2022-01-06mlxsw: Introduce flex key elements for Spectrum-4Amit Cohen
Spectrum-4 ASIC will support more virtual routers and local ports compared to the existing ASICs. Therefore, the virtual router and local port ACL key elements need to be increased. Introduce new key elements for Spectrum-4 to be aligned with the elements used already for other Spectrum ASICs. The key blocks layout is the same for Spectrum-4, so use the existing code for encode_block() and clear_block(), just create separate blocks. Note that size of `VIRT_ROUTER_MSB` is 4 bits in Spectrum-4, therefore declare it using `MLXSW_AFK_ELEMENT_INST_U32()`, in order to be able to set `.avoid_size_check` to true. Otherwise, `mlxsw_afk_blocks_check()` will fail and warn.

FCH controller clock configuration slightly differs across AMD's SOC architectures. Newer family of SOC only support a 48MHz fix clock while stoney SOC family has a clk_mux to choose 48MHz and 25 MHz clk. At present fixed clk support is only enabled for RV architecture using "is-rv" device property initialized from boot loader. This limit 48MHz fixed clock gate support to RV platform unless we add similar device property in boot loader for other architectures. Add pci_device_id table with Stoney platform id and replace "is-rv" device property check with pci id match to add clk mux support with 25MHz and 48MHz clk support based on clk mux selection. This enable 48Mhz fixed fch clock support by default on all newer SOC's except stoney. Also replace RV with FIXED as a generic naming conventions across all platforms and changed module description.
