2021-04-05power: reset: ltc2952: make trigger delay configurableMarek Czerski
Make trigger delay configurable through device tree with trigger-delay-ms property. Trigger delay is the time to wait before starting shutdown sequence after trigger line assertion. Trigger delay must take into account the OFFT time configured with the capacitor connected to OFFT pin of the LTC2952 chip. Basically, the higher the capacitance connected to OFFT pin, the larger trigger delay must be.

To add support for Sparx5, the dependency on MSCC_OCELOT was removed. However, this increases exposure of the driver question not only to Sparx5 platforms, but to everyone. Hence re-add the dependency on MSCC_OCELOT, and extend it with ARCH_SPARX5, to prevent asking the user about this driver when configuring a kernel without Ocelot and Sparx5 support.

2020-07-28power: reset: add driver for LinkStation power offDaniel González Cabanelas
Some Buffalo LinkStations perform the power off operation, at restart time, depending on the state of an output pin (LED2/INTn) at the ethernet PHY. This pin is also used to wake the machine when a WoL packet is received by the PHY. The driver is required by the Buffalo LinkStation LS421DE (ARM MVEBU), and other models. Without it, the board remains forever halted if a power off command is executed, unless the PSU is disconnected and connected again. Add the driver to provide the power off function and also make the WoL feature to be available.

Pull ARM SoC updates from Arnd Bergmann: "One new platform gets added, the Realtek RTD1195, which is an older Cortex-a7 based relative of the RTD12xx chips that are already supported in arch/arm64. The platform may also be extended to support running 32-bit kernels on those 64-bit chips for memory-constrained machines. In the Renesas shmobile platform, we gain support for "RZ/G1H" or R8A7742, an eight-core chip based on Cortex-A15 and Cortex-A7 cores, originally released in 2016 as one of the last high-end 32-bit designs. There is ongoing cleanup for the integrator, tegra, imx, and omap2 platforms, with integrator getting very close to the goal of having zero code in arch/arm/, and omap2 moving more of the chip specifics from old board code into device tree files. The Versatile Express platform is made more modular, with built-in drivers now becoming loadable modules. This is part of a greater effort for the Android OS to have a common kernel binary for all platforms and any platform specific code in loadable modules. The PXA platform drops support for Compulab's pxa2xx boards that had rather unusual flash and PCI drivers but no known users remaining. All device drivers specific to those boards can now get removed as well.
