2012-01-11ENGR00171544 usb-core: usb host will be broken after system pm testPeter Chen
At i.mx6q sabrelite, there is a usb hub on board. After several suspend suspend/resume iterations, the usb host will be broken. It is IC limitation, and similar with: 574b9641d5846e58273dac6bf80fcf1ff312c5c9 Signed-off-by: Peter Chen <peter.chen@freescale.com> Signed-off-by: make shi <b15407@freescale.com>

There are two couples register for HDMI PHY interrupt/mask: HDMI_FC_INT2, HDMI_FC_MASK2 and HDMI_IH_FC_STAT2, HDMI_IH_MUTE_FC_STAT2. The register can not mixed use it, otherwise the interrupt will missing and not clean. Mask interrupt with HDMI_IH_MUTE_FC_STAT2 so check interrupt should use register HDMI_IH_FC_STAT2.

2011-12-16ENGR00169872-2 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>
