[PATCH 0/3] add support for MCP16502 PMIC

MCP16502 is a Power Management IC from Microchip. It has 4 Buck outputs and 2 LDOs. The buck regulators can be used in two modes: normal(FPWM) and low-power(Auto PFM). This patch series adds support for the MCP16502 PMIC. Andrei Stefanescu (3): regulator: dt-bindings: add MCP16502 regulator bin

Hi Mika, Since the commit commit 720d6a671a6e("PCI: pciehp: Do not handle events if interrupts are masked"), the hotplug support on Qemu Guest(4.120-rc1) with a vfio passthrough device seems to be broken. This is on an ARM64 platform. I am booting a Guest with below command line options with the

[PATCH v5 3/9] spi: Add a driver for the Freescale/NXP QuadSPI controller

This driver is derived from the SPI NOR driver at mtd/spi-nor/fsl-quadspi.c. It uses the new SPI memory interface of the SPI framework to issue flash memory operations to up to four connected flash chips (2 buses with 2 CS each). The controller does not support generic SPI messages. This patch al

From: Bartosz Golaszewski Ethernet doesn't work on da850-evm in legacy boot mode since v4.19. This series addresses two problems I've found. I guess with this kind of intrusive changes in the GPIO driver, other boards may be broken at the moment too. Bartosz Golaszewski (3): ARM: davinci: defi
