This is a note to let you know that I've just added the patch titled MIPS: ingenic: Select CPU_SUPPORTS_CPUFREQ && MIPS_EXTERNAL_TIMER to the 5.10-stable tree which can be found at: http://www.kernel.org/git/?p=linux/kernel/git/stable/stable-queue.git;a=summary The filename of the patch is: mips-ingenic-select-cpu_supports_cpufreq-mips_extern.patch and it can be found in the queue-5.10 subdirectory. If you, or anyone else, feels it should not be added to the stable tree, please let <stable@xxxxxxxxxxxxxxx> know about it. commit d007ad5984aac6220a0b5276cdbaf9f4963a38ac Author: Paul Cercueil <paul@xxxxxxxxxxxxxxx> Date: Sun May 30 18:17:59 2021 +0100 MIPS: ingenic: Select CPU_SUPPORTS_CPUFREQ && MIPS_EXTERNAL_TIMER [ Upstream commit eb3849370ae32b571e1f9a63ba52c61adeaf88f7 ] The clock driving the XBurst CPUs in Ingenic SoCs is integer divided from the main PLL. As such, it is possible to control the frequency of the CPU, either by changing the divider, or by changing the rate of the main PLL. The XBurst CPUs also lack the CP0 timer; the TCU, a separate piece of hardware in the SoC, provides this functionality.
