2012-03-30ENGR00178456 IPUv3 fb:Unblank primary fb only by defaultLiu Ying
This patch changes IPUv3 fb probe function logic to unblank the primary fb only by default so that the secondary fb using IPU DP BG channel won't be unblanked when system boot-ups. This avoids the HDMI fb(as the secondary fb using IPU DP BG channel) is unblanked accidentally without plugging in HDMI cable.

2012-03-14ENGR00174923 - EPDC fb: Stress Test Failure FixedDanny Nold
- Changed workqueues to use strict ordering and one process at a time - Changed mutex ordering in IRQ handler to avoid race condition - Updated 64-bit logic operation to ensure proper logic - Fixed bug in how LUT cancellation case is handled. The wrong index was being used to clear LUT IRQ and IRQ_MASK. - Increased flush_updates timeout to 8s, since it may take several seconds if a long queue of updates is waiting.

Change the vide mode from XGA to 1080P when display blank, the system will hang. It is cause by overflow interrupt will trigger when the video mode change, but clean the interrupt status bit depend on pixewl clock. In blank state the pixel clock is gating so the HDMI PHY can't work. Signed-off-by: Sandor Yu <R01008@freescale.com>
2012-03-09ENGR00176504 - EPDC fb: Reduce number of PxP output buffers to 2Danny Nold
- Changed from one-buffer-per-LUT (up to 16 for EPDCv1.0 and 64 for EPDCv2.0) to using 2 static buffers for PxP output. This is facilitated by the switch to using a single-threaded workqueue to process each update, which guarantees that we can use just 2 buffers without clobbering concurrent updates. - One known limitation: This restricts the SNAPSHOT update scheme to only 2 concurrent updates. So if a user intends to use SNAPSHOT scheme, the EPDC_MAX_NUM_BUFFERS #define should be increased based on the desired number of allowable concurrent updates (with a corresponding penalty in static memory allocation).

2012-03-06ENGR00176159 video: ipuv3-fb: change to timeout semaphore to wait on irq.Zhang Jiejing
change to timeout semaphore to wait on irq. use no timeout semaphore have below issues: 1. since fbmem.c will hold the console_lock() before call PAN_DISPLAY ioictl, if have wrong happens on IPU, IRQ not come, any log printk will not ouput, it will become like a system hang, and developer don't know what's wrong. 2. semaphore don't have timeout, here we can't know irq not come, so hang it infintly. 3. semaphore lock and unlock in different context is a dangous operation. To fix these issue, use timedout version to wait on irq. But for better coding stly to align Kernel Coding Style Doc, better use complete to wait on irq, use semaphre little ugly.

2012-03-01ENGR00175261 - EPDC fb: Remove warning messages from EPDC initDanny Nold
- Remove screen update from probe function. This update is redundant. The update in mxc_epdc_fb_fw_handler() will update and show the tux logo if FB console is added, so this achieves the same effect as the update invocation that was removed. - Remove dmaengine_get(), because SDMA driver returns a failure when cycling through DMA channels. Since it is not essential to register with this call, it has been removed. dmaengine_put() also removed. - Added hw_inialization variable to track whether HW is in process of being initialized. In which case, we do not print an error message when an update is received. Signed-off-by: Danny Nold <dannynold@freescale.com>

Add functionality to parse Audio Data Blocks from EDID data to find out what modes of LPCM are suppored by the HDMI sink device. The parsed settings are saved in the hdmi mfd. The HDMI audio driver will check the settings when the audio stream is opened and will then apply appropriate constraints. If we are unable to read from the EDID, then we default to supporting Basic Audio as defined by the HDMI specification (stereo, 16 bit, 32KHz, 44.1KHz, 48KHz PCM).

2012-01-09ENGR00169872-2 rework hdmi initialization and hotplug sequenceAlan Tull
This commit intends to implement the flowchart and details documented in the HDMI Transmitter Controller User Guide section entitled "Programming Model". Some input is also from the Synopsys API code. The HDMI specification requires HDMI to set itself to VGA DVI mode before reading the EDID. So follow this sequence when HDMI is hotplugged: 1. Hdmi connector is plugged in, HDMI video gets an interrupt. 2. Clear out video mode list. Add only VGA DVI mode to list. 3. Request VGA DVI mode (call fb_set_var()) 4. HDMI video driver will get FB_EVENT_MODE_CHANGE callback and call mxc_hdmi_setup() to set up HDMI. 5. Read the edid and add video modes from edid. Select the video mode that is similar to the command line default. 6. Request VGA DVI mode (call fb_set_var()) 7. HDMI video driver will get FB_EVENT_MODE_CHANGE callback and do mxc_hdmi_setup(). Also included is a workaround for an overflow condition in the HDMI. The frame composer has an arithmetic unit that gets updated every time we write to one of the FC registers. But sometimes, depending on the relation between the tmds and sfr clocks, it may happen that this unit doesn't get updated, even though the registers are holding correct values. The workaround for this is, after completing the controller configuration, to rewrite one of the FC registers (i.e. FC_INVIDCONF) three or four times with the same value, and then follow it up by a SW reset to the TMDS clock domain (MC_SWRSTZ). We clear the overflow condition as described above every time we change video mode. Also an overflow interupt handler will clear the overflow condition if it happens again. This overflow condition is expected (and not a problem) when we are in DVI (non-HDMI) mode, so we do not worry about it in that case. Signed-off-by: Alan Tull <alan.tull@freescale.com>
