ACPI: scan: Add acpi_dev_get_next_consumer_dev()

2022-09-24T17:12:32Z

In commit b83e2b306736 ("ACPI: scan: Add function to fetch dependent of ACPI device") we added a means of fetching the first device to declare itself dependent on another ACPI device in the _DEP method. One assumption in that patch was that there would only be a single consuming device, but this has not held. Replace that function with a new function that fetches the next consumer of a supplier device. Where no "previous" consumer is passed in, it behaves identically to the original function.

platform/x86: int3472: Add get_sensor_adev_and_name() helper

2021-12-13T10:44:48Z

The discrete.c code is not the only code which needs to lookup the acpi_device and device-name for the sensor for which the INT3472 ACPI-device is a GPIO/clk/regulator provider. The tps68470.c code also needs this functionality, so factor this out into a new get_sensor_adev_and_name() helper.

platform/x86: int3472: Split into 2 drivers

2021-12-13T10:44:48Z

The intel_skl_int3472.ko module contains 2 separate drivers, the int3472_discrete platform driver and the int3472_tps68470 I2C-driver. These 2 drivers contain very little shared code, only skl_int3472_get_acpi_buffer() and skl_int3472_fill_cldb() are shared. Split the module into 2 drivers, linking the little shared code directly into both. This will allow us to add soft-module dependencies for the tps68470 clk, gpio and regulator drivers to the new intel_skl_int3472_tps68470.ko to help with probe ordering issues without causing these modules to get loaded on boards which only use the int3472_discrete platform driver. While at it also rename the .c and .h files to remove the cumbersome intel_skl_int3472_ prefix.
