From 9f8023a869dabf55ed91b6b73b133c4ea0232bc1 Mon Sep 17 00:00:00 2001 From: V Sowmya Date: Tue, 28 Feb 2017 17:52:05 +0530 Subject: drivers/intel/mipi_camera: Add MIPI CSI camera SSDT generator Add SSDT generator for MIPI CSI camera to create ACPI objects used by the Intel kernel drivers. * SSDB: Sensor specific database for camera sensor. * PWDB: Power database for all the camera devices. * CAMD: ACPI object to specify the camera device type. BUG=b:36580624 BRANCH=none TEST=Build and boot poppy. Dump and verify that the generated SSDT table has the required entries.
