[PATCH v8 0/3] Add support for Qualcomm A53 CPU clock

[Georgi Djakov]

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:
 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.
