Subject: [PATCH 0/3] Broadcom AVS CPUfreq driver
Date: Fri, 12 Aug 2016 16:25:28 -0700 [thread overview]
Message-ID: <1471044331-2480-1-git-send-email-mmayer@broadcom.com> (raw)
This series contains the CPUfreq driver for Broadcom SoCs that use "AVS
Firmware" for voltage and frequency scaling. All voltage and frequency
transitions are performed by the firmware and are therefore hidden from
Linux.
The driver provides a standard CPUfreq interface to other kernel
components and to userland on the one hand and communicates with the
AVS co-processor on the other.
Communication between the two processors is via shared mailbox
registers and interrupts (ARM -> AVS to tell the firmware that there is
a command to process and AVS -> ARM to tell the driver that a command
finished executing).
