2022-09-24platform/x86: int3472: Support multiple clock consumersDaniel Scally
At present, the tps68470.c only supports a single clock consumer when passing platform data to the clock driver. In some devices multiple sensors depend on the clock provided by a single TPS68470 and so all need to be able to acquire the clock. Support passing multiple consumers as platform data.

2021-12-13platform_data: Add linux/platform_data/tps68470.h fileHans de Goede
The clk and regulator frameworks expect clk/regulator consumer-devices to have info about the consumed clks/regulators described in the device's fw_node. To work around cases where this info is not present in the firmware tables, which is often the case on x86/ACPI devices, both frameworks allow the provider-driver to attach info about consumers to the provider-device during probe/registration of the provider device. The TI TPS68470 PMIC is used x86/ACPI devices with the consumer-info missing from the ACPI tables. Thus the tps68470-clk and tps68470-regulator drivers must provide the consumer-info at probe time. Define tps68470_clk_platform_data and tps68470_regulator_platform_data structs to allow the x86 platform code to pass the necessary consumer info to these drivers.
