From mboxrd@z Thu Jan 1 00:00:00 1970 From: leo.yan@linaro.org (Leo Yan) Date: Thu, 26 Mar 2015 19:13:35 +0800 Subject: [PATCH 0/4] clk: hisilicon: support stub clock Message-ID: <1427368419-22222-1-git-send-email-leo.yan@linaro.org> To: linux-arm-kernel@lists.infradead.org List-Id: linux-arm-kernel.lists.infradead.org This series adds support for hisilicon stub clock driver. On hi6220, the bootloader needs load the firmware image and set info for OPPs; after run into kernel, the stub clock driver is used to communicate w/t firmware for cpu dynamic frequency scaling. So finally s/w will simply write request in sram and send ipc to power controller. These patches have been tested on 96board hikey and will be used by cpufreq driver.
