[PATCH V6 0/5] Add APSS clock controller support for IPQ6018

From: Sivaprakash Murugesan
Date: Wed May 27 2020 - 08:25:03 EST

The CPU on Qualcomm's IPQ6018 devices are primarily fed by APSS PLL and XO,
these are connected to a clock mux and enable block.

This patch series adds support for these clocks and inturn enables clocks
required for CPU freq.

* Split mailbox driver from this series, mailbox changes will sent as a
separate series
* Addressed review comments from Stephen
* Addressed Bjorn comments on apss clk and dt-bindings
* Patch 2 depends on a53 pll dt-bindings
* Re-written PLL found on IPQ platforms as a separate driver
* Addressed stephen's comments on apss clock controller and pll
* Addressed Rob's review comments on bindings
* moved a53 pll binding from this series as it is not applicable, will send
it separately.
* Fixed dt binding check error in patch2
dt-bindings: clock: Add YAML schemas for QCOM A53 PLL
* Restructred the patch series as there are two different HW blocks,
the mux and enable belongs to the apcs block and PLL has a separate HW
* Converted qcom mailbox and qcom a53 pll documentation to yaml.
* Addressed review comments from Stephen, Rob and Sibi where it is applicable.
* Changed this cover letter to state the purpose of this patch series
