2022-11-18drivers/i2c/rv3028c7: Add ACPI generation callbacksJan Samek
Add ACPI generation callback to the driver after obtaining the ACPI HID "MCRY3028" for this device from Microcrystal AG (VID: "MCRY"). Also add I2C bus speed field to the device config structure, which is a required ACPI entry. BUG=none TEST=Disassemble the SSDT table and see whether the device entry "MC28" is generated correctly. Also check whether the RV3028 driver in Linux (drivers/rtc/rtc-rv-3028.c) is bound correctly after adding an ACPI match table to it containing the HID. A proper kernel patch is pending.
