thermal: renesas: rzg3e: Remove stale @trim_offset kernel-doc entry

2026-04-09T19:47:15+00:00

The trim_offset field was removed from struct rzg3e_thermal_priv but its kernel-doc entry was left behind. Remove it to fix the mismatch. Signed-off-by: John Madieu Signed-off-by: Daniel Lezcano Link: https://patch.msgid.link/20260409125916.2244241-1-john.madieu.xa@bp.renesas.com

thermal: renesas: rzg3e: add support for RZ/T2H and RZ/N2H

2026-01-21T18:06:57+00:00

The Renesas RZ/T2H (R9A09G077) and RZ/N2H (R9A09G087) SoCs expose the temperature calibration via SMC SIP and do not have a reset for the TSU peripheral, and use different minimum and maximum temperature values compared to the already supported RZ/G3E. Although the calibration data is stored in an OTP memory, the OTP itself is not memory-mapped, access to it is done through an OTP controller. The OTP controller is only accessible from the secure world, but the temperature calibration data stored in the OTP is exposed via SMC. Add support for retrieving the calibration data using arm_smcc_smc(). Add a compatible for RZ/T2H, RZ/N2H can use it as a fallback.

thermal: renesas: rzg3e: make calibration value retrieval per-chip

2026-01-21T18:02:14+00:00

The Renesas RZ/T2H (R9A09G077) and RZ/N2H (R9A09G087) SoCs expose the temperature calibration data via SMC SIP calls. To prepare for supporting these SoCs, do the following changes. Rename rzg3e_thermal_parse_dt() to rzg3e_thermal_get_syscon_trim(). Move the syscon usage out of rzg3e_thermal_get_calibration() and into rzg3e_thermal_get_syscon_trim() and remove single-use variables from the private state. Place a pointer to rzg3e_thermal_get_syscon_trim() into the chip-specific struct, and use it in the probe function to retrieve the calibration values. Now that syscon usage has been moved out of rzg3e_thermal_get_calibration(), remove it and inline the calibration validation into the probe function. Also, reuse the TSU_CODE_MAX macro to mask the calibration values, as GEMASK(11, 0) and 0xFFF are equivalent, and replace the hardcoded 0xFFF with TSU_CODE_MAX in the calibration validation.

thermal/drivers/rcar_gen3: Convert to DEFINE_SIMPLE_DEV_PM_OPS()

2025-11-20T14:33:45+00:00

Convert the Renesas R-Car Gen3 thermal driver from SIMPLE_DEV_PM_OPS() to DEFINE_SIMPLE_DEV_PM_OPS() and pm_sleep_ptr(). This lets us drop the __maybe_unused annotation from its resume callback, and reduces kernel size in case CONFIG_PM or CONFIG_PM_SLEEP is disabled.

When applied the change commit 19d3a401a617, a conflict appeared resulting into a manual fix. However the new file rzg3e_thermal.c was not added but stayed locally in source tree and miss to be merged with the entire change. Fix this by adding the file back.
