As a reminder (since it has been a while) here are your review remarks to v2 of patch 1: https://lore.kernel.org/platform-driver-x86/CAJZ5v0i2ciLHP-=8eQcZc0v0xCzhKHKpxLC=Kgv6W5E_5=HQJA@mail.gmail.com/ (which both seem to have been addressed) AFAICT you did not have any remarks for v2 of patch 2. Regards, Hans p.s. Dan, if I want to give the IR cam a test run on my own Surface Go (version 1) I guess I may need a sensor driver? Where can I find that sensor driver and what do I need in userspace to test this ? > Daniel Scally (5): > ACPI: scan: Add acpi_dev_get_next_consumer_dev() > ACPI: bus: Add iterator for dependent devices > platform/x86: int3472: Support multiple clock consumers > platform/x86: int3472: Support multiple gpio lookups in board data > platform/x86: int3472: Add board data for Surface Go2 IR camera > > drivers/acpi/scan.c | 40 +++++++--- > drivers/clk/clk-tps68470.c | 13 +++- > drivers/platform/x86/intel/int3472/common.c | 2 +- > drivers/platform/x86/intel/int3472/tps68470.c | 76 ++++++++++++++++--- > drivers/platform/x86/intel/int3472/tps68470.h | 3 +- > .../x86/intel/int3472/tps68470_board_data.c | 54 ++++++++++++- > include/acpi/acpi_bus.h | 15 +++- > include/linux/platform_data/tps68470.h | 7 +- > 8 files changed, 177 insertions(+), 33 deletions(-) >

No, I didn't. However, because acpi_bus_get_acpi_device() becomes acpi_get_acpi_dev() in my tree, I think it's better to route this material through it, if that's not a problem. I've tentatively queued it up for 6.1. Thanks! > p.s. > > Dan, if I want to give the IR cam a test run on my own Surface Go (version 1) > I guess I may need a sensor driver?
