[PATCH v3 0/9] OMAP4 : DSS2 : HDMI support on OMAP4
Adding HDMI support on OMAP4. HDMI is a driver that is similar to the VENC or the DSI driver to support HDMI/DVI sink device. The current design adheres to the DSS2 architecture. It is split into the HDMI DSS driver and HDMI panel driver. HDMI DSS driver (hdmi.c) is responsible for 1.OMAP related configuration such as 1.Listening to the DSS_HDMI irq which signals changes such as hot-plug detect,physical attach/detach. 2.calculate the PLL values based on the TV resolution that is selected 3.configuration of the Mux/GPIO settings. 2.HDMI configuration based on the parameters read from the EDID of the sink device such as: 1. Configuration of the PHY registers. 2. Configuration of the PLL registers and setting of the TMDS clock. 3. Configuration of the DDC to read the EDID data when available. 4. Configuration of the core registers to set: a. set the video registers to the timing and format that is selected. b. set the audio registers based on the EDID value read and user selected parameters. c. Set the AVI info frame registers to configure the auxilary info frame which are repeated. HDMI Panel Driver (hdmi_omap4_panel.c) . This is a panel driver which acts as the controlling device which synchronizes the audio and video portion of the driver.[enable ,disable , notification to audio on suspend etc]. It registers hdmi driver to the omap_dss bus and calls the functionality of the HDMI DSS driver. It is also provides the interface for users 1.To read the EDID contents and also confiure the timings based on EDID. 2.To configure AVI Inforframe based on the the EDID(sink capability). Note : Mux handling with hwmod is dependent on pm_runtime_sync ,so mux with hwmod will be posted once patch series with pm_runtime_sync is done. verified on 4430 SDP ES2.1 - Penguins on HDMI and DVI TV. verified on PANDA ES2.1 - Penguins on HDMI and DVI TV. 1. v10 of omap2,3 hwmod DSS adaptation: http://www.mail-archive.com/linux-omap@vger.kernel.org/msg42914.html 2. v3 of OMAP2PLUS: DSS: Generalize clock names http://www.mail-archive.com/linux-omap@vger.kernel.org/msg43338.html 3. v3 of OMAP4: hwmod DSS support: http://www.mail-archive.com/linux-omap@vger.kernel.org/msg43177.html 4.

OMAP2PLUS-DSS2-Make-members-of-dss_clk_source-generic Changes from V2: 1. separated the gamma function from venc/hdmi clock source switch function. 2. Mutex lock fixed. 3. Removed some enum to be used later from the header file. 4. global variables in hdmi.c moved to hdmi structure. Changes from V1: 1. HDMI to call dss_get_dispc_clock_source instead of directly setting register. 2. All HDMI enumerators are added HDMI prefix. 3. Fixed the mutex position.
