[PATCH v2 0/5] Hi3660: enable power management features

[PATCH v2 0/5] Hi3660: enable power management features

[Leo Yan]

Since hi3660 drivers have been merged into Linux kernel (mailbox driver is in
Linux-next branch and other drivers are existed in Linux mainline kernel), so
this patch series is to enable power management features on hi3660.

This patch series includes device tree binding for mailbox, stub clock and CPU
OPPs, and has one patch to consolidate the Kconfigs for driver modules.

This patch set have been tested on Hikey960 and also verified the patch 'hisi:
Consolidate the Kconfigs for the CLOCK_STUB and the MAILBOX' for Hikey620.

Changes from v1:
* Changed patch subject from "dts: arm64: hi3660" to "arm64: dts: hi3660".

[PATCH v2 5/5] hisi: Consolidate the Kconfigs for the CLOCK_STUB and the MAILBOX

[Leo Yan]

From: Daniel Lezcano <daniel.lezcano@linaro.org>

The current defconfig is inconsistent as it selects the mailbox and
the clock for the hi6220 and the hi3660 without having their Kconfigs
making sure the dependencies are correct. It ends up when selecting
different versions for the kernel (for example when git bisecting)
those options disappear and they don't get back, leading to unexpected
behaviors. In our case, the cpufreq driver does no longer work because
the clock fails to initialize due to the clock stub and the mailbox
missing.

In order to have the dependencies correctly set when defaulting, let's
do the same as commit 3a49afb84ca074e ("clk: enable hi655x common clk
automatically") where we select automatically the driver when the
parent driver is selected. With sensible defaults in place, we can leave
other choices for EXPERT.
