2022-07-28regulator: Consumer load management improvementsMark Brown
Merge series from Douglas Anderson <dianders@chromium.org>: The main goal of this series is to make a small dent in cleaning up the way we deal with regulator loads. The idea is to add some extra functionality to the regulator "bulk" API so that consumers can specify the load using that.

Local variable 'p' is initialized by an address of field of acpi_resource, so it does not make sense to compare 'p' with NULL. Found by Linux Verification Center (linuxtesting.org) with SVACE.

2022-07-27Merge branch 'erdma' into rdma.git for-nextJason Gunthorpe
Cheng Xu says ==================== This v14 patch set introduces the Elastic RDMA Adapter (ERDMA) driver, which released in Apsara Conference 2021 by Alibaba. The PR of ERDMA userspace provider has already been created [1]. ERDMA enables large-scale RDMA acceleration capability in Alibaba ECS environment, initially offered in g7re instance. It can improve the efficiency of large-scale distributed computing and communication significantly and expand dynamically with the cluster scale of Alibaba Cloud. ERDMA is a RDMA networking adapter based on the Alibaba MOC hardware. It works in the VPC network environment (overlay network), and uses iWarp transport protocol. ERDMA supports reliable connection (RC). ERDMA also supports both kernel space and user space verbs. Now we have already supported HPC/AI applications with libfabric, NoF and some other internal verbs libraries, such as xrdma, epsl, etc,. For the ECS instance with RDMA enabled, our MOC hardware generates two kinds of PCI devices: one for ERDMA, and one for the original net device (virtio-net). They are separated PCI devices. ==================== * branch 'erdma': RDMA/erdma: Add driver to kernel build environment RDMA/erdma: Add the ABI definitions RDMA/erdma: Add the erdma module RDMA/erdma: Add connection management (CM) support RDMA/erdma: Add verbs implementation RDMA/erdma: Add verbs header file RDMA/erdma: Add event queue implementation RDMA/erdma: Add cmdq implementation RDMA/erdma: Add main include file RDMA/erdma: Add the hardware related definitions RDMA: Add ERDMA to rdma_driver_id definition Signed-off-by: Jason Gunthorpe <jgg@nvidia.com>

2022-07-27media: cedrus: hevc: Add check for invalid timestampJernej Skrabec
Not all DPB entries will be used most of the time. Unused entries will thus have invalid timestamps. They will produce negative buffer index which is not specifically handled. This works just by chance in current code. It will even produce bogus pointer, but since it's not used, it won't do any harm. Let's fix that brittle design by skipping writing DPB entry altogether if timestamp is invalid.

Some platforms have power regulators for slots or devices below Root Ports.

Add an .add_bus() hook (called when pci_alloc_child_bus() allocates the secondary ("child") bus for a bridge), and look for such regulators. If we find some, enable them before bringing up the link and enumerating devices on the child bus. Similarly, when pci_remove_bus() calls the ops->remove_bus() hook, disable the regulators. The regulators that may be described in a Root Port DT device are: vpcie3v3 vpcie3v3aux vpcie12v These control power to the device downstream from the Root Port.

2022-07-27clocksource/drivers/tegra186: Put Kconfig option 'tristate' to 'bool'Daniel Lezcano
The clocksources are built-in, they are not modules. We don't know if the core time framework is ready for clockevents / clocksources as modules. Revert back this option to 'bool'.

2022-07-27clocksource/drivers/timer-ti-dm: Make driver selection bool for TI K3Tony Lindgren
The clocksource drivers do not currently have loadable modules as pointed out by Daniel Lezcano <daniel.lezcano@linaro.org>. Let's reconsider this later on once timer removal discussion has been done, and set timer-ti-dm to bool for TI K3 SoC.

Add compatible for ti,am654-timer to support the timers. For example, am654 has four timers in the MCU domain and 12 timers in the MAIN domain.

2022-07-27clocksource/drivers/timer-ti-dm: Make timer selectable for ARCH_K3Tony Lindgren
Let's make timer-ti-dm selectable for ARCH_K3, and add a separate option for OMAP_DM_SYSTIMER as there should be no need for it on ARCH_K3. For older TI SoCs, we are already selecting OMAP_DM_TIMER in arch/arm/mach-omap*/Kconfig. For mach-omap2, we need to now also select OMAP_DM_SYSTIMER.

2022-07-27clocksource/drivers/timer-ti-dm: Move inline functions to driver for am6Tony Lindgren
The __omap_dm_timer_* inline functions in the header are no longer needed outside the driver, and the header ifdefs prevent the driver working for ARCH_K3. Let's move the inline functions to the driver and drop the ifdefs and drop the unused functions __omap_dm_timer_override_errata() and __omap_dm_timer_load_start().

2022-07-27hwmon: (aquacomputer_d5next) Add support for Aquacomputer Quadro fan controllerAleksa Savic
Extend aquacomputer_d5next driver to expose hardware temperature sensors and fans of the Aquacomputer Quadro fan controller, which communicates through a proprietary USB HID protocol. Implemented by Jack Doan [1]. Four temperature sensors and PWM controllable fans are available. The liquid flow sensor is also exposed, implemented by Leonard Anderweit [2]. Additionally, serial number, firmware version and power-on count are exposed through debugfs. This driver has been tested on x86_64.
