Cristian, I only kept your R-b for patch 1, dropped your other R-b tags, because there are some changes to address the comments from Sudeep. Most changes are only to dump the information in probe phase, update to single sysfs single value for syslog. Sudeep, I saw you sent out PR to Arnd for 6.17, so no rush now for this patchset. Take your time.
This patchset was originally submitted before v6.16-rc6. As the kernel has now reached v6.17-rc2, I would greatly appreciate it if you could take some time to review it when convenient. Thank you in advance! Thanks, Peng
Hope I not miss any comments from V1. Thanks, Peng System Manager firmware provides API to dump board, silicon, firmware information. It also provides API to dump system sleep, wakeup information. So add the interface for Linux to retrieve the information: patch 1 is to add doc for board information which was missed before. Signed-off-by: Peng Fan <peng.fan@nxp.com> --- Changes in v2: - Add more info in patch 1 for documentation(attribute is reserved for future use, boardname may not align with the board name in device tree) - Drop dump silicon revision API - Update discover build info, cfg info, board info API to be only used in probe phase - Update to use single sysfs single value for syslog. - Link to v1: https://lore.kernel.org/r/20250627-sm-misc-api-v1-v1-0-2b99481fe825@nxp.com (local) --- Peng Fan (6): firmware: arm_scmi: imx: Add documentation for MISC_BOARD_INFO firmware: arm_scmi: imx: Support discovering buildinfo of MISC protocol firmware: arm_scmi: imx: Support getting cfg info of MISC protocol firmware: arm_scmi: imx: Support getting board info of MISC protocol firmware: arm_scmi: imx: Support getting syslog of MISC protocol firmware: imx: sm-misc: Dump syslog info .../firmware/arm_scmi/vendors/imx/imx-sm-misc.c | 190 +++++++++++++++++++++ drivers/firmware/arm_scmi/vendors/imx/imx95.rst | 22 +++ drivers/firmware/imx/sm-misc.c | 178 +++++++++++++++++++ include/linux/scmi_imx_protocol.h | 19 +++ 4 files changed, 409 insertions(+) --- base-commit: e88d17c7335a917e98b7c65776cbe3358210e8ab change-id: 20250627-sm-misc-api-v1-85c030c670c6 Best regards, -- Peng Fan [off-list ref]
