It supports a number of Asynchronous and Synchronous interfaces
and has various settings to configure the bus interface.

The DT bindings define all the various GPMC settings.

As the GPMC supports multiple devices on the bus, each
device is represented as a child and the respective

watchdog: introduce a u-boot,autostart property 2022-10-24T09:09:19+00:00 Rasmus Villemoes rasmus.villemoes@prevas.dk 2022-09-27T09:54:03+00:00 27836705839c4751ac28239ee6fa1f3984e46d4d This is a companion to u-boot,noautostart. If one has a single watchdog device that one does want to have auto-started, but several others that one doesn't, the only way currently is to set the CONFIG_WATCHDOG_AUTOSTART and then use the opt-out for the majority. The main motivation for this is to add an autostarted watchdog device to the sandbox (to test a fix) without having to set AUTOSTART in sandbox_defconfig and add the noautostart property to the existing devices. But it's also nice for symmetry, and the logic in init_watchdog_dev() becomes simpler to read because we avoid all the negations. Signed-off-by: Rasmus Villemoes <rasmus.villemoes@prevas.dk>

pmic: Convert pm8916 driver to a generic Qcom PMIC driver 2022-08-26T14:55:45+00:00 Sumit Garg sumit.garg@linaro.org 2022-08-04T14:27:17+00:00 e555d4caacd008b5091a8d755bdfff1ce8cceb2f Since both pm8916.c and pm8916_gpio.c are already supporting multiple Qcom SoCs, it makes sense to rename these drivers to pmic_qcom.c and qcom_pmic_gpio.c respectively. Also, these driver can be extended to support additional functionality if required for other Qcom SoCs.

watchdog: add pulse support to gpio watchdog driver 2022-07-21T06:09:06+00:00 Paul Doelle paaull.git@gmail.com 2022-07-04T09:00:25+00:00 1fc45d6483d77b9fbe84e546f4e6afe665ba827a A common external watchdog circuit is kept alive by triggering a short pulse on the reset pin. This patch adds support for this use case, while making the algorithm configurable in the devicetree. The "linux,wdt-gpio" driver being modified is based off the equivalent driver in the Linux kernel, which provides support for this algorithm. This patch brings parity to this driver, and is kept aligned with the functionality and devicetree configuration in the kernel. It should be noted that this adds a required property named 'hw_algo' to the devicetree binding, following suit with the kernel. I'm happy to make this backward-compatible if preferred.
