Subject: [PATCH v10 0/6] Add support for Qualcomm A53 CPU clock
Date: Fri, 1 Dec 2017 19:02:18 +0200 [thread overview]
Message-ID: <20171201170224.25053-1-georgi.djakov@linaro.org> (raw)
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 v9 (https://lkml.org/lkml/2017/9/21/511)
* Added the clock properties to the APCS DT node, instead of adding a subnode
and also replaced patch "mailbox: qcom: Populate APCS child platform devices"
with "mailbox: qcom: Create APCS child device for clock controller".
* Dropped patch "mailbox: qcom: Move the apcs struct into a separate header",
and use dev_get_regmap(dev->parent) in the child driver.
* Addressed Bjorn's comments on a53-pll and apcs-clk drivers.
* Added SPDX copyright identifiers.
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.
