This series tackles the Rockchip RK356x SoC dtsi files in a few different ways. First, it updates the lower and upper voltage limits and the exact voltages for the Rockchip RK356x CPU OPPs, using the most conservative per-OPP values for different SoC bins. This is rather similar to the already performed adjustment of the GPU OPP voltages. [1] Next, this series prepares the RK356x SoC dtsi files for per-variant OPPs, with the RK3566T being the first new RK356x SoC variant to be introduced. This follows the approach used for the RK3588 SoC variants. [2] Lastly, this series introduces new SoC dtsi for the RK3566T variant, which is capable of operating at the CPU and GPU OPPs/frequencies lower than the "full-fat" RK3566 variant's. The RK3566T is found on some of the already supported boards and rather importantly, this stops the CPU cores and the GPU from being overclocked on these boards.
