Patches do the following: - patch 1/11 selects CONFIG_PM for the watchdog driver - patch 2/11 adds clock and reset support for watchdog - patches 3-7/11 adds fixes and cleanup for the watchdog driver - patch 8/11 adds suspend to RAM to the watchdog driver (to be used by RZ/G3S) - patch 9/11 documents the RZ/G3S support - patches 10-11/11 add device tree support It is expected that the clock and device tree support will go through Geert's tree while the rest of the patches through the watchdog tree. Thank you, Claudiu Beznea Changes in v2: - added patch "watchdog: rzg2l_wdt: Select PM" - propagate the return status of rzg2l_wdt_start() to it's callers in patch "watchdog: rzg2l_wdt: Use pm_runtime_resume_and_get()" - propagate the return status of rzg2l_wdt_stop() to it's callers in patch "watchdog: rzg2l_wdt: Check return status of pm_runtime_put()" - removed pm_ptr() from patch "watchdog: rzg2l_wdt: Add suspend/resume support" - s/G2UL/G2L in patch "dt-bindings: watchdog: renesas,wdt: Document RZ/G3S support" - collected tags Claudiu Beznea (11): clk: renesas: r9a08g045: Add clock and reset support for watchdog watchdog: rzg2l_wdt: Select PM watchdog: rzg2l_wdt: Use pm_runtime_resume_and_get() watchdog: rzg2l_wdt: Check return status of pm_runtime_put() watchdog: rzg2l_wdt: Remove reset de-assert on probe/stop watchdog: rzg2l_wdt: Remove comparison with zero watchdog: rzg2l_wdt: Rely on the reset driver for doing proper reset watchdog: rzg2l_wdt: Add suspend/resume support dt-bindings: watchdog: renesas,wdt: Document RZ/G3S support arm64: dts: renesas: r9a08g045: Add watchdog node arm64: dts: renesas: rzg3s-smarc-som: Enable the watchdog interface .../bindings/watchdog/renesas,wdt.yaml | 1 + arch/arm64/boot/dts/renesas/r9a08g045.dtsi | 14 +++ .../boot/dts/renesas/rzg3s-smarc-som.dtsi | 5 + drivers/clk/renesas/r9a08g045-cpg.c | 3 + drivers/watchdog/Kconfig | 1 + drivers/watchdog/rzg2l_wdt.c | 111 ++++++++++-------- 6 files changed, 85 insertions(+), 50 deletions(-)
