There are systems where multiple camera sensors share a single TPS68470, so we need to extend the driver to support them. This requires a couple of tweaks to the ACPI functions to fetch dependent devices, which also assumes that only a single dependent will be found. Series level changes in v2: - Dropped the patch that added a terminator to the existing tps68470 board data The v1 can be found here: https://lore.kernel.org/platform-driver-x86/20220216225304.53911-1-djrscally@gmail.com/ Thanks Dan 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 | 37 ++++++--- 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 | 49 +++++++++++- include/acpi/acpi_bus.h | 15 +++- include/linux/platform_data/tps68470.h | 7 +- 8 files changed, 169 insertions(+), 33 deletions(-)
