[PATCH v8 0/3] Add support for Qualcomm A53 CPU clock
From: Georgi Djakov
Date: Fri Jun 23 2017 - 12:15:43 EST
This patchset adds support for the A53 CPU clock and allows scaling
of the CPU frequency on msm8916 based platforms.
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:
* 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
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.
