[PATCH v3 0/4] clk: tegra: add DFLL support for Tegra114
From: Svyatoslav Ryhel
Date: Tue Aug 26 2025 - 02:11:54 EST
DFLL is a dedicated clock source for the Fast CPU. The DFLL is based on
a ring oscillator and translates voltage changes into frequency
compensation changes needed to prevent the CPU from failing and is
essential for correct CPU frequency scaling.

Changes in v2:
- dropped 'drivers:' from commit title
- aligned naming to Tegra114
Changes in v3:
- add DFLL support for Tegra 114 was split into dt header addition,
DFLL reset configuration and CVB tables implementation.
- added cleaner commit message to dt header commit
- added T210_ prefixes to Tegra210 CVB table macros
