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>

2012-01-09Revert "tty: serial: imx: Allow UART to be a source for wakeup"Alan Tull
This reverts commit 6565023ad182d3347972aad3f1a13ba57266e81a.
2012-01-09tty: serial: imx: Allow UART to be a source for wakeupFabio Estevam
Allow UART to be a source for wakeup from low power mode. Tested on a mx6sabrelite (where ttymxc1 is the console) by doing: echo enabled > /sys/devices/platform/imx-uart.1/tty/ttymxc1/power/wakeup echo mem > /sys/power/state and then pressing a key in the console will wakeup the sytem.

On Audio class, the wLength field of the Setup packet, contains the data payload size of the following Data phase. Instead of harcoding values, use wLength. This also fixes a bug where Gadget driver had to receive 3 bytes, but it was queueing a ZLP. Signed-off-by: Felipe Balbi <balbi@ti.com>
2012-01-09usb: gadget: audio: actually support both speedsFelipe Balbi
While testing g_audio with HighSpeed UDC on a FS Hub, we had no configurations to present to the host. That's because both speeds where mutually exclusive. Signed-off-by: Felipe Balbi <balbi@ti.com>
2012-01-09USB: gadget: section mismatch warning fixedMichal Nazarewicz

However, being callback functions they were referenced from structures in “normal” sections. Changing the tag from “__init” to “__ref” fixes the warnings.
