ARM: versatile: move integrator/realview/vexpress to versatile

2022-04-04T08:22:37+00:00

These are all fairly small platforms by now, and they are closely related. Just move them all into a single directory. Cc: Linus Walleij Cc: Liviu Dudau Cc: Lorenzo Pieralisi Tested-by: Sudeep Holla Acked-by: Sudeep Holla Signed-off-by: Arnd Bergmann

clk: versatile: Rename ICST to CLK_ICST

2021-10-15T01:00:25+00:00

For consistency, prefix the ICST config option with CLK as all other clock source drivers have.

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. Cc: Lorenzo Pieralisi Cc: Linus Walleij Reviewed-by: Sudeep Holla Acked-by: Liviu Dudau Signed-off-by: Rob Herring

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.
