From db03874b854368c14f21bdc41f1044cf6cda6200 Mon Sep 17 00:00:00 2001 From: Bjorn Andersson Date: Mon, 4 Oct 2021 20:25:28 -0700 Subject: dt-bindings: thermal: qcom: add HC variant of adc-thermal monitor bindings The HC generation of the ADC Thermal Monitor is quite similar to the 5th generation, but differs in valid values for a few properties. Create a new binding for the HC version of the hardware, rather than sprinkle conditionals throughout the existing binding.

The driver now uses the devm_reset_control_array_get() function, so reset-names is no longer required, but keep it for legacy reasons.
