From ce5b5bef86c3062a4ea01af4b774fd9f180fd4d3 Mon Sep 17 00:00:00 2001 From: Ryan Walklin Date: Fri, 7 Jun 2024 21:20:33 +1200 Subject: [PATCH] cpufreq: sun50i: add Allwinner H700 speed bin Support for the Allwinner H618, H618 and H700 was added to the sun50i cpufreq-nvmem driver recently [1] however at the time some operating points supported by the H700 (1.008, 1.032 and 1.512 GHz) and in use by vendor BSPs were found to be unstable during testing, so the H700 speed bin and the 1.032 GHz OPP were not included in the mainline driver. Retesting with kernel 6.10rc2 (which carries additional fixes for the driver) now shows stable operation with these points. Add the H700 speed bin to the driver.
