Revert "ARM: vexpress: Don't select VEXPRESS_CONFIG"

2020-05-28T10:30:33+00:00

This reverts commit 848685c25da99d871bbd87369f3c3d6eead661ac.
Due to when I set 'depends on VEXPRESS_CONFOG=Y' in 'config
POWER_RESET_VEXPRESS' to get an allmodconfig build on arm64 to build,
and allmodconfig build on arm fails if this patch isn't reverted.

ARM: vexpress: Don't select VEXPRESS_CONFIG

2020-05-13T17:42:47+00:00

CONFIG_VEXPRESS_CONFIG has 'default y if ARCH_VEXPRESS', so selecting is
unnecessary. Selecting it also prevents setting CONFIG_VEXPRESS_CONFIG
to a module.

bus: vexpress-config: Merge vexpress-syscfg into vexpress-config

2020-05-13T17:42:46+00:00

The only thing that vexpress-syscfg does is provide a regmap to
vexpress-config bus child devices. There's little reason to have 2
components for this. The current structure with initcall ordering
requirements makes turning these components into modules more difficult.

So let's start to simplify things and merge vexpress-syscfg into
vexpress-config. There's no functional change in this commit and it's
still separate components until subsequent commits.

clk: versatile: Rework kconfig structure

2020-05-05T16:43:14+00:00

CONFIG_COMMON_CLK_VERSATILE doesn't really do anything other than hiding
Arm Ltd reference platform clock drivers. It is both selected by the
platforms that need it and has a 'depends on' for those platforms. Let's
drop the selects and convert CONFIG_COMMON_CLK_VERSATILE into a
menuconfig entry. With this make CONFIG_ICST visible.

Move the 'select REGMAP_MMIO' to the drivers that require it (SP810 did
not).

This also has the side effect of enabling CONFIG_ICST for COMPILE_TEST
as it was not visible before.

ARM: vexpress: Move vexpress_flags_set() into arch code

2020-05-05T16:42:39+00:00

vexpress_flags_set() is only used by the platform SMP related code and
has nothing to do with the vexpress-sysreg MFD driver other than both
access the same h/w block. It's also only needed for 32-bit systems and
must be built-in for them. Let's move vexpress_flags_set() closer to
where it is being used. This will allow for vexpress-sysreg to be built
as a module.

ARM: vexpress: Set-up shared OPP table instead of individual for each CPU

2019-12-09T11:52:50+00:00

Currently we add individual copy of same OPP table for each CPU within
the cluster. This is redundant and doesn't reflect the reality.

We can't use core cpumask to set policy->cpus in ve_spc_cpufreq_init()
anymore as it gets called via cpuhp_cpufreq_online()->cpufreq_online()
->cpufreq_driver->init() and the cpumask gets updated upon CPU hotplug
operations. It also may cause issues when the vexpress_spc_cpufreq
driver is built as a module.

Since ve_spc_clk_init is built-in device initcall, we should be able to
use the same topology_core_cpumask to set the opp sharing cpumask via
dev_pm_opp_set_sharing_cpus and use the same later in the driver via
dev_pm_opp_get_sharing_cpus.
