45f780a061 omap1: omap_udc: Add clocking and disable vbus sense for omap7xx
The l3_ocpi_ck clock is needed on omap7xx processors for USB.
Additionally, bit 8 of the SOFT_REQ_REG needs to be enabled for
the usb_dc_ck on omap7xx, which is a different bit than that
of the omap16xx-defined clock of the same name.

I added a provision for the usb_dc_ck and l3_ocpi_ck clocks as
dc_clk and hhc_clk, respectively, for omap7xx CPUs.  Additionally,
I added a check in machine_without_vbus_sense for all omap7xx
devices, as presently I know of no omap7xx-based devices that
have vbus sense, and it made more sense to me to use a cpu check
here than to spell out each machine one at a time.  Finally, DMA
is disabled for omap7xx, as it causes problems with these chips.

490a566522 omap1: mmc: Add platform init for omap7xx
The MMC mux pins normally used by omap chips in devices.c
are different from what is needed by omap7xx chips.  This
change adds a conditional around the mux setup code to
enable the correct mux pins.

The omap730 and omap850 both use a different clock for the "fck"
clock of the MMC interface than other omap processors based on the
SOFT_REQ_REG, pin 12.  The "ick" clock is the same as that used
by other omap processors.

* Added the missing clock definition as mmc3_ck to clock.h
* Added the clock definition to omap_clks in clock.c
* Added CK_7XX to the mmci-omap.0 "ick" clock already in clock.c

With these changes, it is now possible to initialize and use MMC
cards with omap730 and omap850 devices.

d9f5007491 omap: introduce OMAP_LL_DEBUG_NONE DEBUG_LL config
Zoom2/Zoom3 kind of boards do not use omap uarts for console.
These use external debug board for console.

So these boards should not have "Uncompressing Kernel...."
log put on omap uarts.

By interoducing OMAP_LL_DEBUG_NONE option,
unnecessary writes to omap uarts is avoided.

In future, the DEBUG_LL interface will be enhanced
to use external debug board.

9d30b99f35 omap: Eliminate OMAP_MAX_NR_PORTS
Eliminate OMAP_MAX_NR_PORTS

Note that also the null terminator entry for omap1
serial_platform_data needs to be now removed to avoid
oopsing.

Note that mach-omap1 uses struct plat_serial8250_port
array, which requires a null terminator at the end,
and that's why we need to use ARRAY_SIZE - 1. This
is not needed on mach-omap2 as the array used is
struct omap_uart_state, and does not use a null
terminator.

This is needed only on sil rev's ES3.0 and above.

This patch enables the above needed WA in the SDRC power register

The original SDRC POWER register value is stored and restored back

instead of just waiting for a fixed amount of time.

867d320b6c PM: Disable usb host HW save and restore
The hardware SAVEANDRESTORE mechanism seems to leave
USB HOST power domain permanently into active state
after one transition from off to active state.
Disabling for now.

692ec4abb9 OMAP: Store reboot mode in scratchpad on OMAP34xx
The reboot mode can be communicated to a bootloader (or the
kernel itself) with a scratchpad register. This functionality
is especially useful, if userspace is allowed to change
the reboot mode.
