Gregory Changelog: v4 -> v5: - Rebased onto v5.0-rc1 - Rewrite the clk_get part in armada_8k_get_sharing_cpus() - Reverse the call function order in armada_8k_cpufreq_exit() v3 -> v4: - Remove most of the global variable and use the private data of the platfrom device to store the freq_tables struct. - Remove the clk pointer of the freq_table struct which is no more needed with the new way to register the opp - Check the get_cpu_device() return. - Balance the clk_get() calls. - No more use the devm_ function. - Base the registration of the opp on the cpu mask updated after each iteration to find the shared cpus. - Base the free on the NULL or 0 value of the freq_table struct members, it allows to remove the global index. v2 -> v3 - Make the driver really modular (modprobe;modprobe -r;modprobe; is working) - Don't use anymore 100MHz as minimal frequency, but only max frequency/4 - Fix remaining warning reported by checkpatch - Rework the registering of the opp v1 -> v2: - Fix typos in MAINTAINERS (reported by Baruch Siach) and in armada-8k-cpufreq.c (reported by Thomas Petazzoni) - Fix indentation in Kconfig.arm (reported by Thomas Petazzoni) - Use const for opps_div (reported by Thomas Petazzoni) - Fix memory leak of opps_array (reported by Thomas Petazzoni) Gregory CLEMENT (2): MAINTAINERS: add new entries for Armada 8K cpufreq driver cpufreq: ap806: add cpufreq driver for Armada 8K MAINTAINERS | 1 + drivers/cpufreq/Kconfig.arm | 11 ++ drivers/cpufreq/Makefile | 1 + drivers/cpufreq/armada-8k-cpufreq.c | 203 ++++++++++++++++++++++++++++ 4 files changed, 216 insertions(+) create mode 100644 drivers/cpufreq/armada-8k-cpufreq.c
