- Configure ipu1_di0 tob e sourced from the VIDEO_PLL(PLL5) and hardcode frequency to (455000000/3)Mhz. This value, further divided, can yield frequencies close enough to support 1080p, 720p, 1024x768, and 640x480 modes. This is not ideal but it's an improvement comparing to the only hardcoded 1024x768 mode. - Fix memory leaks if attach method failed - Print EDID when -v passed to the kernel

/*

|
* We need a clock management system that works across unrelated SoCs and
|
|
* devices. For now, to keep imx development moving, define some barebones
|
|
* functionality that can be shared within the imx family by having each SoC
|
|
* implement functions with a common name.
|
|
*
|
|
* The usb enable functions are best-effort. They turn on the usb otg, host,
|
|
* and phy clocks in a SoC-specific manner, but it may take a lot more than that
|
|
* to make usb work on a given board. In particular, it can require specific
|
|
* pinmux setup of gpio pins connected to external phy parts, voltage regulators
|
|
* and overcurrent detectors, and so on. On such boards, u-boot or other early
|
|
* board setup code has to handle those things.
