This pull request contains the second batch of changes for Broadcom ARM-based SoCs, please pull the following: - Nicolas declares a CMA area within the first 1GB of DRAM in order for it to be guaranteed to reside there, otherwise ARM64's memory initialization will pick up a CMA area within ZONE_DMA32 - Stefan adds the Device Tree node for the built-in Ethernet controller (GENET) on the Raspberry Pi 4 model B board * tag 'arm-soc/for-5.5/devicetree-part2' of https://github.com/Broadcom/stblinux: ARM: dts: bcm2711-rpi-4: Enable GENET support ARM: dts: bcm2711: force CMA into first GB of memory Link: https://lore.kernel.org/r/20191118182931.11884-1-f.fainelli@gmail.com Signed-off-by: Olof Johansson

Device tree fixes for omap variants for for v5.5 merge window This series of changes contains fixes for few SoC and board specific issues that would be good to have merged for v5.5-rc1: - Fix incorrect MMC card detection polarity for omap3-tao3530 - Fix wrong am57xx-beagle-x15 pinmux named states for eMMC - Fix dra7 cpsw mdio clock that causes wrong speed - Fix vcsi for droid4 so it won't get turned off after init - Fix rev and sysconfig register offsets for omap4 sgx so it can idle Then there are also two minor late changes to logicpd-torpedo-baseboard to configure 1-wire HDQ for battery stats, and remove out of date workaround comments no longer needed. * tag 'omap-for-v5.5/dt-fixes-merge-window-signed' of git://git.kernel.org/pub/scm/linux/kernel/git/tmlind/linux-omap: ARM: dts: Fix sgx sysconfig register for omap4 ARM: dts: Fix vcsi regulator to be always-on for droid4 to prevent hangs ARM: dts: dra7: fix cpsw mdio fck clock ARM: dts: am57xx-beagle-x15: Update pinmux name to ddr_3_3v ARM: dts: omap3-tao3530: Fix incorrect MMC card detection GPIO polarity ARM: dts: logicpd-torpedo: Remove unnecessary notes/comments ARM: dts: logicpd-torpedo-baseboard: Enable HDQ Link: https://lore.kernel.org/r/pull-1574870758-237468@atomide.com Signed-off-by: Olof Johansson

Few ti-sysc related fixes for v5.5 merge window Just few minor changes that can be merged when suitable, but would be good to have these in v5.5-rc1 to remove dependencies between branches for more changes later on in v5.6: - Add quirk handling for AESS (Audio Engine Sub System) - We want to drop the useless gptimer option for omap4 as there are local timers - A minor error path handling improvment for sysc_child_add_named_clock() that will make further patching a bit easier * tag 'omap-for-v5.5/ti-sysc-late-signed' of git://git.kernel.org/pub/scm/linux/kernel/git/tmlind/linux-omap: bus: ti-sysc: Adjust exception handling in sysc_child_add_named_clock() ARM: OMAP2+: Drop useless gptimer option for omap4 bus: ti-sysc: Add module enable quirk for audio AESS Link: https://lore.kernel.org/r/pull-1574273726-31367@atomide.com Signed-off-by: Olof Johansson

ARM: multi_v7_defconfig: Restore debugfs support

2019-12-06T15:13:26Z

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.

ARM: 8947/1: Fix __arch_get_hw_counter() access to CNTVCT

2019-12-06T11:51:03Z

__arch_get_hw_counter() should check clock_mode to see if it can access CNTVCT. With the conversion to unified vDSO this check has been left out. This causes on imx v6 and v7 (imx_v6_v7_defconfig) and other platforms to hang at boot during the execution of the init process as per below: [ 19.976852] Run /sbin/init as init process [ 20.044931] Kernel panic - not syncing: Attempted to kill init! exitcode=0x00000004 Fix the problem verifying that clock_mode is set coherently before accessing CNTVCT.

ARM: 8943/1: Fix topology setup in case of CPU hotplug for CONFIG_SCHED_MC

2019-12-06T11:51:02Z

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 Reviewed-by: Lukasz Luba Tested-by: Lukasz Luba Tested-by: Ondrej Jirman Signed-off-by: Dietmar Eggemann Signed-off-by: Russell King

ARM: defconfig: re-run savedefconfig on multi_v* configs

2019-12-05T21:20:18Z

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
