Enabling idle mode during audio playback causes the glitches on OMAP5
HDMI. The TRM also suggests to use no-idle for HDMI audio playback.
This patch sets HDMI idle mode to no-idle for the duration of the
playback, and restores it back to original value afterwards.

One of the reasons for having the simplefb nodes in /chosen, and doing
explicit enumeration of the nodes there, is too allow enumerating them sooner,
so that we get a console earlier on.
Doing this earlier then fs_initcall is not useful, since the fb only turns
into a console when fbcon intializes, which is a fs_initcall too.

At the moment we have one function, hdmi_pll_enable, which enables the
PLL and writes the PLL configuration to registers.
To make the HDMI PLL ahere to the DSS PLL API, split the hdmi_pll_enable

hdmi_pll_set_config which writes the config.

HDMI PLL code needs the pointer to the WP block so that it can manage
its power. Currently this is passed as a function parameter to
hdmi_pll_enable and hdmi_pll_disable. To make the PLL function adhere to

This patch stores the WP pointer to hdmi_pll_data in hdmi_pll_init, so
that it's available when needed.

OMAP DSS currently contains two different PLLs: DSI PLL (Type A PLL) and
HDMI PLL (Type B PLL). When DRA7 support is added, we will also support
Video PLLs (Type A).
The driver currently handles all PLLs totally separately. This patch
adds common DSS PLL code, which
a) lets us have common code for the PLLs
b) lets the users of the PLLs use a common API, instead of DSI API or
HDMI API.

When DPI uses the DSI PLL for pixel clock, the DPI code will call
dsi_runtime_get/put to keep the DSI block enabled. A much simpler way to
handle this is to do dsi_runtime_get/put in DSI's dsi_pll_init() and
dsi_pll_uninit(), thus removing the need for DSI to call the runtime PM
functions.

The DSS PLL has support to power on the PLL's highspeed clock output
and HSDIV output separately. In practice both need to powered on, as in
most OMAP's that's the only working configuration. We already do that in
dsi_pll_init(), by overriding the passed arguments so that both are
always powered.
Simplify the code by removing the support for choosing which outputs to
power on.
