2023-02-13platform/x86: dell-ddv: Prefer asynchronous probingArmin Wolf
During probe, both sensor buffers need to be queried to initialize the hwmon channels. This might be slow on some machines, causing a unnecessary delay during boot. Mark the driver with PROBE_PREFER_ASYNCHRONOUS so that it can be probed asynchronously.

2023-02-13platform/x86: dell-ddv: Add hwmon supportArmin Wolf
Thanks to bugreport 216655 on bugzilla triggered by the dell-smm-hwmon driver, the contents of the sensor buffers could be almost completely decoded. Add an hwmon interface for exposing the fan and thermal sensor values. Since the WMI interface can be quite slow on some machines, the sensor buffers are cached for 1 second to lessen the performance impact. The debugfs interface remains in place to aid in reverse-engineering of unknown sensor types and the thermal buffer.

configuration Currently hotplug configuration in logic device assumes that all items are provided with no holes. Thus, any group of hotplug events, associated with the specific status/event/mask registers is configured in those registers successively from bit zero to bit #n (#n < 8). This logic is changed int order to allow non-successive definition to support configuration with the skipped bits – for example bits 3, 5, 7 in status/event/mask registers can be associated with hotplug events, while others can be skipped.

2023-02-13platform: mellanox: Split logic in init and exit flowVadim Pasternak
Split logic in mlxplat_init()/mlxplat_exit() routines. Separate initialization of I2C infrastructure and others platform drivers. Motivation is to provide synchronization between I2C bus and mux drivers and other drivers using this infrastructure. I2C main bus and MUX busses are implemented in FPGA logic. On some new systems the numbers allocated for these busses could be variable depending on order of initialization of I2C native busses. Since bus numbers are passed to some other platform drivers during initialization flow, it is necessary to synchronize completion of I2C infrastructure drivers and activation of rest of drivers. Thus initialization flow will be performed in synchronized order.

2023-02-13bnxt_en: Fix mqprio and XDP ring checking logicMichael Chan
In bnxt_reserve_rings(), there is logic to check that the number of TX rings reserved is enough to cover all the mqprio TCs, but it fails to account for the TX XDP rings. So the check will always fail if there are mqprio TCs and TX XDP rings. As a result, the driver always fails to initialize after the XDP program is attached and the device will be brought down. A subsequent ifconfig up will also fail because the number of TX rings is set to an inconsistent number. Fix the check to properly account for TX XDP rings. If the check fails, set the number of TX rings back to a consistent number after calling netdev_reset_tc(). Fixes: 674f50a5b026 ("bnxt_en: Implement new method to reserve rings.")

Create a new register definition file in the "reg" subdirectory, and begin populating it with GSI register definitions based on IPA version. The GSI registers haven't changed much, so several IPA versions can share the same GSI register definitions. As with IPA registers, an array of pointers indexed by GSI register ID refers to these register definitions, and a new "regs" field in the GSI structure is initialized in gsi_reg_init() to refer to register information based on the IPA version (though for now there's only one). The new function gsi_reg() returns register information for a given GSI register, and the result can be used to look up that register's offset. This patch is meant only to put the infrastructure in place, so only eon register (CH_C_QOS) is defined for each version, and only the offset and stride are defined for that register. Use new function gsi_reg() to look up that register's information to get its offset, This makes the GSI_CH_C_QOS_OFFSET() unnecessary, so get rid of it.
