2019-12-09ARM: vexpress: Set-up shared OPP table instead of individual for each CPUSudeep Holla
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.

Add ADC support to stm32mp157c-ed1 board. Following ADC signals are dedicated for analog and routed to connectors: - ADC1/2 in0 (ANA0) - ADC1/2 in1 (ANA1) - ADC1 in6 (PF12) Configure ADC1 with these signals. But keep it disabled by default, so PF12 can be used as gpio by default. Add VDD and VDDA supplies to ADC on stm32mp157c-ed1 board. This allows to get full ADC analog performances in case VDDA is below 2.7V (not the case by default).

2019-12-09ARM: dts: e60k02: fix power buttonAndreas Kemnade
The power button was only producing irqs, but no key events, Forced power down with long key press works, so probably only a short spike arrives at the SoC. Further investigation shows that LDORTC2 is off after boot of the vendor kernel. LDORTC2 is shared with a GPIO at the pmic which probably transfers the button press to the SoC. That regulator off at boot, so "regulator-boot-on" is definitively wrong. So remove that. Reported-by: H.

On the LS1021A-TSN board, the 2 Atheros AR8031 PHYs for eth0 and eth1 have interrupt lines connected to the shared IRQ2_B LS1021A pin. Switching to interrupts offloads the PHY library from the task of polling the MDIO status and AN registers (1, 4, 5) every second. Unfortunately, the BCM5464R quad PHY connected to the switch does not appear to have an interrupt line routed to the SoC.

Commit fd7d58f0dbc3 ("ARM: multi_v7_defconfig: renormalize based on recent additions") removed explicit enable line for CONFIG_DEBUG_FS, because that feature has been selected by other enabled options: CONFIG_TRACING, which were enabled by CONFIG_PERF_EVENTS. In meantime, commit 0e4a459f56c3 ("tracing: Remove unnecessary DEBUG_FS dependency") removed the dependency between CONFIG_DEBUG_FS and CONFIG_TRACING, so CONFIG_DEBUG_FS is no longer enabled in default builds. Enable it again explicitly, as debugfs support is essential for various automated testing tools.

2019-12-06ARM: 8943/1: Fix topology setup in case of CPU hotplug for CONFIG_SCHED_MCDietmar Eggemann
Commit ca74b316df96 ("arm: Use common cpu_topology structure and functions.") changed cpu_coregroup_mask() from the ARM32 specific implementation in arch/arm/include/asm/topology.h to the one shared with ARM64 and RISCV in drivers/base/arch_topology.c. Currently on ARM32 (TC2 w/ CONFIG_SCHED_MC) the task scheduler setup code (w/ CONFIG_SCHED_DEBUG) shows this during CPU hotplug: ERROR: groups don't span domain->span It happens to CPUs of the cluster of the CPU which gets hot-plugged out on scheduler domain MC. Turns out that the shared cpu_coregroup_mask() requires that the hot-plugged CPU is removed from the core_sibling mask via remove_cpu_topology(). Otherwise the 'is core_sibling subset of cpumask_of_node()' doesn't work. In this case the task scheduler has to deal with cpumask_of_node instead of core_sibling which is wrong on scheduler domain MC. e.g. CPU3 hot-plugged out on TC2 [cluster0: 0,3-4 cluster1: 1-2]: cpu_coregroup_mask(): CPU3 cpumask_of_node=0-2,4 core_sibling=0,3-4 ^ should be: cpu_coregroup_mask(): CPU3 cpumask_of_node=0-2,4 core_sibling=0,4 Add remove_cpu_topology() to __cpu_disable() to remove the CPU from the topology masks in case of a CPU hotplug out operation. At the same time tweak store_cpu_topology() slightly so it will call update_siblings_masks() in case of CPU hotplug in operation via secondary_start_kernel()->smp_store_cpu_info(). This aligns the ARM32 implementation with the ARM64 one. Guarding remove_cpu_topology() with CONFIG_GENERIC_ARCH_TOPOLOGY is necessary since some Arm32 defconfigs (aspeed_g5_defconfig, milbeaut_m10v_defconfig, spear13xx_defconfig) specify an explicit # CONFIG_ARM_CPU_TOPOLOGY is not set w/ ./arch/arm/Kconfig: select GENERIC_ARCH_TOPOLOGY if ARM_CPU_TOPOLOGY Fixes: ca74b316df96 ("arm: Use common cpu_topology structure and functions") Reviewed-by: Sudeep Holla <sudeep.holla@arm.com> Reviewed-by: Lukasz Luba <lukasz.luba@arm.com> Tested-by: Lukasz Luba <lukasz.luba@arm.com> Tested-by: Ondrej Jirman <megous@megous.com> Signed-off-by: Dietmar Eggemann <dietmar.eggemann@arm.com> Signed-off-by: Russell King <rmk+kernel@armlinux.org.uk>
2019-12-05ARM: defconfig: re-run savedefconfig on multi_v* configsOlof Johansson
This is mostly to reorder the entries as they've moved in the Kconfig hierarchies. Doing this periodically (but not very often) simplifies conflict resolution for new options, etc. Link: https://lore.kernel.org/r/20191205211438.27552-2-olof@lixom.net Signed-off-by: Olof Johansson <olof@lixom.net>

This brings in the mainline tree right after armsoc contents was merged this release cycle, so that we can re-run savedefconfig, etc. Signed-off-by: Olof Johansson <olof@lixom.net>
