* drivers: add missing SPDX-License-IdentifierAhmad Fatoum2021-11-011-0/+1
| | | | | | | | | | | | | | | | | | | | This adds the suitable SPDX-License-Identifier to all files in drivers/ that previously lacked one. To aid manual inspection, following heuristics can be used: * No changes outside of comments/whitespace: git show -U0 HEAD | rg -v '^(@@|diff|index)|[-+]([-+]|//|#|[\s/]\*)' * -or-later come in pairs: git show --inter-hunk-context=19 HEAD | \ perl -0777 -F'/^@/gm' -ne 'for (@F) { @m = /later/g; print if @m & 1 }' Signed-off-by: Ahmad Fatoum <a.fatoum@pengutronix.de> Link: https://lore.barebox.org/20211030175632.2276077-4-a.fatoum@pengutronix.de Signed-off-by: Sascha Hauer <s.hauer@pengutronix.de>

* watchdog: add support for Intel TCO watchdog timerAhmad Fatoum2021-05-031-0/+1
| | | | | | | | | | | | | | | | | | Variants of the iTCO are integrated into many Intel southbridges. They are most often accessed via PCI. Add a driver for the variant found in the q35 QEMU machine. It should be straight forward to extend the itco_chipset_info array to support more variants in future as the need arises. To test, use: qemu-system-x86_64 -M q35 -global ICH9-LPC.noreboot=false The last option corresponds to a pin strap option, which can't be influenced from within the VM.

* watchdog: add support for at91sam9/sama5 watchdogAhmad Fatoum2020-07-111-0/+1
| | | | | | | | | | | | | | The watchdog on these SoCs is enabled by default on system boot, so a driver is especially useful. According to data sheet the mode register containing the timeout can be configured only once, but I couldn't verify this on the sama5d2. Regardless, the driver takes care not to change the mode register unless necessary. Implementation that want to leave to the OS the decision which timeout to choose, can just keep pinging with the POR-default of 16 seconds and the OS will be able to set the final timeout.

* watchdog: add stm32 watchdog and reset driverAhmad Fatoum2019-06-191-0/+1
| | | | | | | | | | The driver supports setting watchdog timeout, system reset and querying reset reason. Disabling watchdog isn't possible in hardware, thus users should either only enable it before boot or have the poller take care of feeding it.

* watchdog: new driver for Armada XPUwe Kleine-König2017-03-311-0/+1
| | | | | | | | | | This SoC uses a variant of the IP that is also used on most other Marvell SoCs. For now it only supports Armada XP but the naming is already chosen such that adding support for further SoCs doesn't result in much renaming.

| | | | | | | | | | | | Also move reset_cpu() for jz4755 SoC from platform code into the new driver code. At the moment mach-xburst lacks clk support so jz4740 watchdog driver looks like a template.
