This patch introduces a simple watchdog driver for Qualcomm devices. Some devices, including one I have been spending a lot of time with, the LG G7 ThinQ (codename judyln, arch sdm845) will reset within 30 seconds if the watchdog is not serviced.
I have tested this patch from Casey Connolly that is over a year old and has not yet been upstreamed, and it is very useful to me. I can hardly use u-boot on this device without it. I have received Casey's permission to work on upstreaming this patch. This is my first contribution to U-Boot, and I am unfamiliar with mailing list workflows, so please be patient :) Signed-off-by: Paul Sajna <he...@paulsajna.com> --- Changes in v2: - Add watchdog start - Add watchdog reset - Remove stop from the probe function - Use dev_err instead of printf - Update Casey's name - Add myself as an author - - Link to v1: https://lore.kernel.org/r/20250413-b4-qcom-wdt-v1-1-db42cb93d...@paulsajna.com --- Casey Connolly (1): watchdog: qcom: introduce qcom-wdt driver Paul Sajna (1): watchdog: qcom: improve driver with more functionality configs/qcom_defconfig | 2 + drivers/watchdog/Kconfig | 7 +++ drivers/watchdog/Makefile | 1 + drivers/watchdog/qcom-wdt.c | 118 ++++++++++++++++++++++++++++++++++++++++++++ 4 files changed, 128 insertions(+) --- base-commit: 0eebdd17888005751cd77cf3794c5292d36f481a change-id: 20250413-b4-qcom-wdt-e7b913fc375e Best regards, -- Paul Sajna <he...@paulsajna.com>
