i.MX95 System Manager(SM) BBM protocol exports two RTCs for EVK board. one RTC is SoC internal RTC, the other is board RTC. The current driver only use the 1st RTC. With this patchset, both RTCs could be used in Linux. To achieve this: 1. Support more event sources for BBM protocol 2. Add bbm_info hook to let users could query the number of RTCs 3. Introduce devm_rtc_allocate_device_priv to support setting rtc device private information 4. Update rtc-imx-sm-bbm.c to register both RTCs Signed-off-by: Peng Fan <peng.fan@xxxxxxx> --- Peng Fan (4): firmware: arm_scmi: imx: Support more event sources firmware: arm_scmi: imx: Introduce bbm_info hook rtc: Introduce devm_rtc_allocate_device_priv rtc: imx-sm-bbm: Support multiple RTCs drivers/firmware/arm_scmi/vendors/imx/imx-sm-bbm.c | 33 ++++++++++- drivers/rtc/class.c | 9 ++- drivers/rtc/dev.c | 8 ++- drivers/rtc/interface.c | 16 ++--- drivers/rtc/proc.c | 2 +- drivers/rtc/rtc-imx-sm-bbm.c | 69 ++++++++++++++-------- include/linux/rtc.h | 2 + include/linux/scmi_imx_protocol.h | 2 + 8 files changed, 100 insertions(+), 41 deletions(-) --- base-commit: e7bb221a638962d487231ac45a6699fb9bb8f9fa change-id: 20250116-rtc-3834e01786a8 Best regards, -- Peng Fan <peng.fan@xxxxxxx>
