This patch series: - adds generic LSPCON infoframe setup functions. - registers these functions into existing AVI infoframe framework. - triggers these functions from modeset sequence. Next patches in the series will add vendor specific code. V2: Added new parameter to align with new definition of drm_hdmi_avi_infoframe_quant_range V3: Added r-b from Maarten (for V2) Added new parameter output_format in struct lspcon to accommodate Ville's review comments on last patch of the series V4: Addressed Ville's review comment - Do not add output_format in LSPCON state, as its non-atomic. Add this into CRTC state (added in a later patch).
