Subject: [PATCH v1] ACPI: LPSS: drop BayTrail and Lynxpoint pinctrl HIDs
Date:   Tue,  3 Oct 2023 13:52:33 +0530
Message-Id: <20231003082233.30118-1-raag.jadav@intel.com>
Precedence: bulk

Platform devices are now created by ACPI core on device enumeration
on acpi_bus_scan() -> acpi_bus_attach() path after commit 48459340b92b
("ACPI / scan: use platform bus type by default for _HID enumeration").
No need to create them from LPSS unless we explicitly need to set
acpi_lpss_pm_domain for them.
