Subject: [PATCH v9 0/7] Add support for Qualcomm A53 CPU clock
This patchset adds support for the A53 CPU clock on MSM8916 platforms
and allows scaling of the CPU frequency on msm8916 based platforms.
Changes since v8 (https://lkml.org/lkml/2017/6/23/476)
* Converted APCS mailbox driver to use regmap and to populate child
platform devices that will handle the rest of the functionality
provided by APCS block.
* Picked Rob's Ack for the PLL binding.
* Changed the APCS binding and put it into a separate patch.
* Addressed review comments.
* Minor changes.
Changes since v7 (https://lkml.org/lkml/2016/10/31/296)
* Add the APCS clock controller to the APCS driver to expose both the
mailbox and clock controller functionality as discussed earlier:
https://lkml.org/lkml/2016/11/14/860
* Changed the a53pll compatible string as suggested by Rob.
Changes since v6 (https://lkml.org/lkml/2016/9/7/347)
* Addressed various comments from Stephen Boyd
Changes since v5 (https://lkml.org/lkml/2016/2/1/407)
* Rebase to clk-next and update according to the recent API changes.
Changes since v4 (https://lkml.org/lkml/2015/12/14/367)
* Convert to builtin drivers as now __clk_lookup() is used
Changes since v3 (https://lkml.org/lkml/2015/8/12/585)
* Split driver into two parts - and separate A53 PLL and
A53 clock controller drivers.
* Drop the safe switch hook patch. Add a clock notifier in
the clock provider to handle switching via safe mux and
divider configuration.
Changes since v2 (https://lkml.org/lkml/2015/7/24/526)
* Drop gpll0_vote patch.
* Switch to the new clk_hw_* APIs.
* Rebase to the current clk-next.
Changes since v1 (https://lkml.org/lkml/2015/6/12/193)
* Drop SR2 PLL patch, as it is already applied.
* Add gpll0_vote rate propagation patch.
* Update/rebase patches to the current clk-next.
