[PATCH 0/6] firmware: tegra: bpmp: Add Tegra410 ACPI MBWT support

[Aniruddha Rao]

Tegra410, an ACPI-based platform, provides Memory Bandwidth Throttler
(MBWT) controls for PCIe and GPU connected over chip-to-chip link
(Nv-Clink) traffic on the path to DRAM. These controls are accessible
through BPMP firmware.

The current Tegra BPMP driver depends on Device Tree based transport
setup and does not support ACPI-based platforms. This series keeps the
existing DT path unchanged, adds ACPI support to the BPMP driver,
defines the MBWT BPMP ABI, adds Tegra410 MBWT helper functions, and
exposes a narrow sysfs interface for ACPI-based Tegra410 systems when
firmware reports support for the required MBWT requests.
