thermal: Kernel driver for OC event handling

2020-06-11T21:23:53+00:00

Why?
In case of an OC(Over Current) event in Tegra SOC,
BPMP gets an interrupt indicating the same. However,
there is no indication to ccplex and userspace about
the same. This driver provides the interface between
BPMP OC implementation and userspace.

How?
Once there is an EDP OC interrupt to BPMP, BPMP writes
to a Shared mailbox register dedicated for BPMP and CCPLEX
communication for EDP OC. Once the interrupt is received,
Kernel reads the OC status registers to realize the state
of the EDP OC HW. The kernel driver provides interfaces
for Userspace to poll for the status/interrupts count.

Thermal: governor: Continuous fan control

2019-05-09T21:42:53+00:00

Create new thermal governor called "continuous_therm_gov" to make pwm-fan
run more quietly and more smoothly.

This governor will filter the raw temp with IIR filter and caculate the
pwm value, these pwm values ramp point to point intead of step to step.

thermal: Add userspace-alert cooling device

2018-08-02T09:34:19+00:00

Provides the facility for userspace to know whether thermal alert
occurred or not for a particular temperature trip value.
This is supported by adding a SW thermal cooling device.

thermal: Add kernel base overlay headers

2018-05-31T21:32:11+00:00

Some compilers do not directly take the base kernel version
header files present in the exact path of the drivers.

Hence, it is required to mention the source headers explicitly.

firmware: tegra: add NV_TEGRA_BPMP to build

2018-01-11T14:40:42+00:00

BPMP driver was moved from linux-4.9 repository. Modify Makefiles and
Kconfig files to add driver as part of build.

Also rename downstream BPMP driver Kconfig to NV_TEGRA_BPMP to
differentiate it from upstream driver that is available in recent
kernel versions. Also add mention about it in menuconfig options.
