* eqos: use phy reset low power mode from DTSushil Singh2021-05-12
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Issue: Some ethernet PHY consume low power only when they are put in reset mode otherwise power consumption is high. Fix: Add DT flag which can be set for the PHYs which consume low power when they are in reset. Driver puts those phy chip to reset mode for low power consumption state if the corresponding dt flag is set, else use supported low power mode operation for the selected phy. Default operation is to use phy reset mode for low power consumption.

* pwm: fan: Add support for always on fanMantravadi Karthik2020-12-25
| | | | | | | | | | | | | | | | | | | | | | | | | Why? In case of continuous governor, the fan-poweron pwm value is assumed to be at index 1 of pwm values. In case of tmargin the pwm table would be reversed (high to low) and hence the assumption is invalid. How? While calculating the pwm value in the case of continuous governor, add a check if the cooling device is always on fan. If true, for all values of temp, pwm should be calculated instead of assigning 0.

| | | | | | | | | | | | | | | | | | | | | | | | | | Why? Tmargin feature uses reverse pwm mapping in DT. The current rru/rrd calculation logic assumes that the pwm table is in ascending order.

* therm-fan-est: Add support for Tmargin to drive fanmkarthik2020-09-15
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Why? Tmargin method of fan control allows multiple groups of therma-fan-est devices temperatures to be considered for the fan control algorithm/fan curve. The limitation of the existing max temp algorithm in therm-fan-est driver is that devices with different fan curves cannot be accomodated in the driver. In case, there are multple fan curves, the device which has the steepest curve wins the algoritm. Hence, taking the temperatures as a reference from their respective critical temperatures and using that value to drive the fan will help in accomodating both the devices' fan curves. How? * Calculate the effective crit temp of all the thermal zones during probe. * In the polling cycles, calculate the effective temperatures of the individual groups and use the tmargin formula to calculate the current temperature. * Since the Tmargin temp trip values are in reverse order, we need to use the reverse order in the pwm-fan dt profile. * The hysterysis is subtracted from the temp in cooling scenario to avoid frequent switching at trip temps. Since the tmargin trip values are taken in the decending order, hysterysis temps in dt should be given as negative values.

* thermal: pwm-fan: Add tach feedback supportmkarthik2020-09-02
| | | | | | | | | | | | | | | | | | | | | | | | | | | | Why? The current implementation of the pwm-fan driver only writes a pwm value to the HW when requested. There is no tachometer rpm read back to check if the thermal performance is as expected. This change aims to add the rpm offsets necessary to maintain the desired fan rpm. How? A new work queue is added which gets the pwm fan rpm and checks the same for a rpm diff tolerance value. In case the tolerance value is exceeded, the next pwm corresponding to the next rpm ramp index is written to the pwm controller.

* thermal: fix cpu throttling for floorswept partsSrikar Srimath Tirumala2020-08-10
| | | | | | | | | | | | | | | | | | | | | | | | | | | | Make CPU throttling use cpufreq policy instead of querying the CCF. As CPU clocks are not supported by CCF on T194, querying max and min CPU frequencies from CCF is not guaranteed to work. Secondly, clocks for floorswept CPUs are not available and this results in a pesky warning about failing to get a clock. While it is not required to get all the CPU clocks for throttling to work, the first reason requires a change. Fix this by using the values stored in the policy struct instead. Also defer the registration of the cooling devices if cpufreq has not already been registered. Update the binding doc to reflect this change and clarify per CPU throttling is not supported.
