watchdog: Add support for Armada 37xx CPU watchdog

2018-10-13T13:19:39Z

This adds support for the CPU watchdog found on Marvell Armada 37xx SoCs. There are 4 counters which can be set as CPU watchdog counters. This driver uses the second counter (ID 1, counting from 0) as watchdog counter, and first counter (ID 0) to implement pinging on the second counter without the need to disable it. Since counters IDs 2 and 3 are enabled already before even U-Boot starts, this driver does not use them at all, for example by adding a device tree property for counter selection.

watchdog: lantiq: Convert to watchdog_device

2018-10-02T11:32:26Z

Instead of doing the ioctl handling manually just use register a watchdog_device and let the watchdog framework do the ioctl handling. This also removes the ltq_wdt_bootstatus_set typedef and replaces it with a structure providing the chip specific functions pointer. The watchdog_init_timeout() function is now used and the initial timeout can be provided in device tree. If the watchdog was already activated it will not be stopped any more, but the settings from the driver will be used and the watchdog subsystem will take care.

Pull GPIO updates from Linus Walleij: "This is the bulk of GPIO changes for the v4.17 kernel cycle: New drivers: - Nintendo Wii GameCube GPIO, known as "Hollywood" - Raspberry Pi mailbox service GPIO expander - Spreadtrum main SC9860 SoC and IEC GPIO controllers. Improvements: - Implemented .get_multiple() callback for most of the high-performance industrial GPIO cards for the ISA bus. - ISA GPIO drivers now select the ISA_BUS_API instead of depending on it. This is merged with the same pattern for all the ISA drivers and some other Kconfig cleanups related to this. Cleanup: - Delete the TZ1090 GPIO drivers following the deletion of this SoC from the ARM tree. - Move the documentation over to driver-api to conform with the rest of the kernel documentation build. - Continue to make the GPIO drivers include only and not the too broad that we want to get rid of. - Managed to remove VLA allocation from two drivers pending more fixes in this area for the next merge window. - Misc janitorial fixes" * tag 'gpio-v4.17-1' of git://git.kernel.org/pub/scm/linux/kernel/git/linusw/linux-gpio: (77 commits) gpio: Add Spreadtrum PMIC EIC driver support gpio: Add Spreadtrum EIC driver support dt-bindings: gpio: Add Spreadtrum EIC controller documentation gpio: ath79: Fix potential NULL dereference in ath79_gpio_probe() pinctrl: qcom: Don't allow protected pins to be requested gpiolib: Support 'gpio-reserved-ranges' property gpiolib: Change bitmap allocation to kmalloc_array gpiolib: Extract mask allocation into subroutine dt-bindings: gpio: Add a gpio-reserved-ranges property gpio: mockup: fix a potential crash when creating debugfs entries gpio: pca953x: add compatibility for pcal6524 and pcal9555a gpio: dwapb: Add support for a bus clock gpio: Remove VLA from xra1403 driver gpio: Remove VLA from MAX3191X driver gpio: ws16c48: Implement get_multiple callback gpio: gpio-mm: Implement get_multiple callback gpio: 104-idi-48: Implement get_multiple callback gpio: 104-dio-48e: Implement get_multiple callback gpio: pcie-idio-24: Implement get_multiple/set_multiple callbacks gpio: pci-idio-16: Implement get_multiple callback ...

watchdog: Add Nuvoton NPCM watchdog driver

2018-03-24T09:19:39Z

The Nuvoton NPCM750 has a watchdog implemented as a single register inside the timer peripheral. This driver exposes that watchdog as a standard watchdog device with coarse timeout intervals, limited by the combination of prescaler and counter that is provided by the hardware. The calculation is taken from the Nuvoton vendor tree. The watchdog is left running if a bootloader had it going. The rate is the one specified in the device tree, or the default value (obtained from the datasheet). There is a pre-timeout IRQ that is wired up. This timeout always occurs 1024 clocks before the timeout. Signed-off-by: Joel Stanley Reviewed-by: Guenter Roeck Signed-off-by: Guenter Roeck Signed-off-by: Wim Van Sebroeck
