Normally the omapdss driver gets the regulators using the regulator
names assigned for omapdss. However, in an effort to get a minimal DSS
support for DT enabled kernel on selected boards, we will add omapdss
devices and platform data the old way even for DT kernel. This causes
the problem that omapdss cannot find the regulators using omapdss's
regulator names.
This patch creates a temporary workaround for DSI and HDMI by trying to
get the regulators also using native OMAP4 regulator names.

The SPI driver makes a gpio_request during initialization. The requested
gpios need to be populated as part of the s3c64xx_spi_driver_data so that
they can be released during suspend and requested again during resume.
Add the missing code to save the requested gpios as part of the driver
data. This fixes a SPI driver suspend crash.

USBCKCR is controlling USB parent clock and divide rate.
This parent clock is used as a "usb24s" from other devices,
but the "divide rate" is not used.
Further, this clock itself is known as "usb24".
So, to set this clock is a little confusable.
This patch adds quick explain and sample settings for this clock.

Convert spc_emulate_modesense() to use a table of mode pages, rather
than a switch statement. This makes it possible to add more pages
sanely -- in particular we no longer need to make sure we keep the
0x3f (return all mode pages) case in sync.
While we're touching this code, make our MODE SENSE emulation a bit
better in a couple of ways:
- When the initiator passes PC == 1 asking for changeable values,
return all 0s to show we don't support setting anything.
- Return a block descriptor for disk devices.
