Hi ARM-SoC guys,
Olof had confused this with PSCI[0]. I assume the confusion is now resolved ? I have now rebased the series on top of v4.3-rc1 and just resending them again.
Please pull this series for v4.4
You can access it from: git://linux-arm.org/linux-skn.git juno_dvfs
BUT the ARM external git repository is still unreliable and hence I am avoiding pull request. Can I request to pull it from the mails directly instead ? Extremely sorry for the inconvenience.
Regards, Sudeep
This patch series adds support for: 1. SCPI(System Control and Power Interface) mailbox protocol driver. It uses ARM MHU mailbox controller driver on Juno but can work with any mailbox controllers using standard mailbox APIs 2. Add support for clocks provided by SCP firmware through the SCPI interface 3. Using the existing arm_big_little cpufreq driver and the newly added SCPI clock driver, it also adds support for CPU DVFS on ARM64 JUNO development platforms.
The SCPI protocol document is available @[1]
