This software initiated reset performs, in the end, a hardware system reset using SWRST_REQ of RSTCTRL register. The watchdog itself is able to control directly the hardware system reset without any operation done by the interrupt handler. This feature allows the watchdog to not depend on the software to reset the system when a watchdog timeout occurs. Indeed, when the watchdog timeout occurs, the watchdog requests a system reset using its own hardware dedicated line but this reset source is disabled at the reset controller level. To benefit of this feature and be robust against software issues, enable watchdogs reset sources.

Asserting these resets after boot would silently break interrupt delivery with no driver to restore them. Mark the DMA resets as critical by adding them to the crit_resets table in the SoC-specific rzg2l_cpg_info for r9a07g043, r9a07g044, and r9a08g045, preventing __rzg2l_cpg_assert() from asserting them and ensuring they are deasserted during probe and resume.

Add rzg2l_mod_enable_crit_clock_init_mstop() which walks all module clocks on resume, re-enables any critical clock found disabled, and then restores the MSTOP state for clocks that have one via the existing helper.

2026 11:43:12 +0000 Subject: [PATCH 25/25] clk: renesas: Add support for RZ/G3L SoC The clock structure for RZ/G3L is almost identical to that of the RZ/G3S SoC with more IP blocks such as LCDC, CRU, LVDS, and GPU. Add minimal clock and reset entries required to boot the system on Renesas RZ/G3L SMARC EVK and bind it with the RZ/G2L CPG core driver.
