On the 7275 the GEXP device declares OperationRegion (BAR0, SystemMemory, SB04, 0x0208) and the I2C4 controller (INT3446) builds its _CRS from the same SB04 variable, so intel_lpss_acpi fails with -EBUSY unless acpi_enforce_resources=lax is given. Thierry's patch 1/8 fixes it here too once a "Latitude 7275" entry is added to intel_lpss_quirk_dmi[]. I'll send that as a small patch on top of his series; Thierry, if you would rather fold it into v11, I'm happy to provide a Tested-by. The other 5285 quirk, the static clock consumer list for the broken INT3479 _DEP, is not needed on the 7275: tps68470-clk already lists i2c-INT3479:00 as a consumer in clk_summary. Thanks, D.
