From 6434cf630086eea2d091f122f5802582a05d9d1c Mon Sep 17 00:00:00 2001 From: Animesh Manna Date: Mon, 20 Jun 2022 12:21:38 +0530 Subject: drm/i915/bios: calculate panel type as per child device index in VBT MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Each LFP may have different panel type which is stored in LFP data data block. Based on the child device index respective panel-type/ panel-type2 field will be used. v1: Initial rfc verion. v2: Based on review comments from Jani, - Used panel-type instead addition panel-index variable. - DEVICE_HANDLE_* name changed and placed before DEVICE_TYPE_* macro. v3: - passing intel_bios_encoder_data as argument of intel_bios_init_panel(). Passing NULL to indicate encoder is not initialized yet for dsi as current focus is to enable dual EDP. [Jani] v4: - encoder->devdata used which is initialized before from vbt structure.
