2022-05-22habanalabs: unified memory manager infrastructureYuri Nudelman
This is a part of overall refactoring attempt to separate nic and the core drivers. Currently, there are 4 different flows, that contain very similar code. These are the ts, nic, hwblocks and cb alloc/map flows. The similar aspect of all these flows is that they all contain a central store, with memory buffers inside, supporting the following set of operations: - Allocate buffer and return handle - Get buffer from the store with handle - Put the buffer (last put releases the buffer) - Map the buffer to the user This patch contains a generic data structure used to implement the above memory buffer store interface. Conversion of the existing code to use the new data structure will follow.

2022-05-22habanalabs: replace usage of found with dedicated list iterator variableJakob Koschel
To move the list iterator variable into the list_for_each_entry_*() macro in the future it should be avoided to use the list iterator variable after the loop body. To *never* use the list iterator variable after the loop it was concluded to use a separate iterator variable instead of a found boolean [1]. This removes the need to use a found variable and simply checking if the variable was set, can determine if the break/goto was hit.

2022-05-22habanalabs/gaudi: avoid resetting max power in hard resetTomer Tayar
The default max power is deduced from the card type value in the CPU-CP info. This value is then set in the max power variable of the device structure. Getting the CPU-CP info is done as part of the late init phase which is called also during reset. This means that a max power value which is modified via sysfs will be reset during hard reset back to the default value. As the max power is updated in any case during device init in hl_sysfs_init(), this setting in late init can be removed, and the overriding during reset is thus avoided.

2022-05-22hwmon: (pmbus) Check PEC support before reading other registersAdam Wujek
Make sure that the support of PEC is determined before the read of other registers. Otherwise the validation of PEC can trigger an error on the read of STATUS_BYTE or STATUS_WORD registers. The problematic scenario is the following. A device with enabled PEC support is up and running and a kernel driver is loaded. Then the driver is unloaded (or device unbound), the HW device is reconfigured externally (e.g. by i2cset) to advertise itself as not supporting PEC. Without the move of the code, at the second load of the driver (or bind) the STATUS_BYTE or STATUS_WORD register is always read with PEC enabled, which is likely to cause a read error resulting with fail of a driver load (or bind).

2022-05-22hwmon: (adt7475) Add support for pin configurationChris Packham
The adt7473, adt7475, adt7476 and adt7490 have pins that can be used for different functions. On the adt7473 and adt7475 this is pins 5 and 9. On the adt7476 and adt7490 this is pins 10 and 14. The first pin can either be PWM2(default) or SMBALERT#. The second pin can be TACH4(default), THERM#, SMBALERT# or GPIO. The adt7475 driver has always been able to detect the configuration if it had been done by an earlier boot stage. Add support for configuring the pins based on the hardware description in the device tree.

2022-05-22hwmon: add driver for the Microchip LAN966x SoCMichael Walle
Add support for the temperatur sensor and the fan controller on the Microchip LAN966x SoC. Apparently, an Analog Bits PVT sensor is used which can measure temperature and process voltages. But only a forumlae for the temperature sensor is known. Additionally, the SoC support a fan tacho input as well as a PWM signal to control the fan.

2022-05-22powerpc/powernv/vas: Assign real address to rx_fifo in vas_rx_win_attrHaren Myneni
In init_winctx_regs(), __pa() is called on winctx->rx_fifo and this function is called to initialize registers for receive and fault windows. But the real address is passed in winctx->rx_fifo for receive windows and the virtual address for fault windows which causes errors with DEBUG_VIRTUAL enabled. Fixes this issue by assigning only real address to rx_fifo in vas_rx_win_attr struct for both receive and fault windows.
