ec/google/chromeec: Update the USBC ACPI device hierarchy
Type C connector class driver in kernel (v5.4) expects the Type C ACPI device under ChromeEC ACPI device scope. Currently the Type C ACPI device is populated under ChromeEC device's parent. This leads to incorrect casting of Type C's parent device and hence a crash. Move the Type C device under ChromeEC ACPI device. BUG=b:153518804 TEST=Build and boot the mainboard. Ensure that the USBC ACPI device is populated under ChromeEC ACPI device. Scope (\_SB.PCI0.LPCB.EC0.CREC) { Device (USBC) { Name (_HID, "GOOG0014") // _HID: Hardware ID ... } } Change-Id: I628489bc420d7a3db4ad3cb93d085d568c6de507 Signed-off-by: Karthikeyan Ramasubramanian <kramasub@google.com> Reviewed-on: https://review.coreboot.org/c/coreboot/+/40354 Tested-by: build bot (Jenkins) <no-reply@coreboot.org> Reviewed-by: Furquan Shaikh <furquan@google.com> Reviewed-by: Aamir Bohra <aamir.bohra@intel.com> Reviewed-by: Tim Wawrzynczak <twawrzynczak@chromium.org>
