eqos: use phy reset low power mode from DT

2021-05-13T01:43:36+00:00

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.

thermal: fix cpu throttling for floorswept parts

2020-08-10T08:23:35+00:00

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.

thermal: throttle: fix for floorswept platforms

2018-07-05T23:53:03+00:00

Pass the clock handles for all the CPU clusters instead of just the
one cluster from DT. The NAFLLL CLUSTER clock id refers to the
physical cluster and is not guaranteed to be present on floorswept
configurations.

Add logic to look for the appropriate clock handle from a list of
clock handles and fail the driver registration if a missing clock
is referenced in the cooling device.

Currently, AON cluster is only one which is not connected.
So, no need to read AXI2APB bridge registers for that NOC.
