Matthias Kaehlcke ca8cbc8391 [ARM] 5552/1: ep93xx get_uart_rate(): use EP93XX_SYSCON_PWRCNT and EP93XX_SYSCON_PWRCN
ep93xx: get_uart_rate() uses the constants EP93XX_SYSCON_CLOCK_CONTROL
and EP93XX_SYSCON_CLOCK_UARTBAUD, which no longer exist. Use
EP93XX_SYSCON_PWRCNT and EP93XX_SYSCON_PWRCNT_UARTBAUD instead

Hartley Sweeten 4070243250 [ARM] 5528/1: ep93xx: add defines for dma clock magic numbers
Update the dma clocks so that the magic numbers are named.

All the dma clocks have an enable bit to turn them on/off as
needed.  Currently these bits are in the code as "magic"
numbers.  This changes all of them to named defines to
improve code readability.

Also, the EP93XX_SYSCON_CLOCK_CONTROL register is improperly
named.  In the EP93xx User's Guide this register is called
PwrCnt (Power Control).  All of the uses of this register
are associated with the clock support so this patch also
modifies the names to match the User's Guide.

Hartley Sweeten e3a6d01932 [ARM] 5526/1: ep93xx: usb driver cleanup
Cleanup the ohci-ep93xx driver.

1) Use the usb.h dbg() macro instead of pr_debug() so that
   the source filename is prefixed to the message and it is
   terminated with a linefeed.

2) Add error handling for the clk_get() call.

3) Update clkdev support so that the usb clock is matched by
   the dev_id instead of the con_id.

Hartley Sweeten ff05c0330b [ARM] 5509/1: ep93xx: clkdev enable UARTS
Fix the clkdev API support for the ep93xx uart clocks.

The uarts available in the ep93xx have individual clock controls.
The current implementation assumes that the bootloader has enabled
the clocks before the kernel has booted. It also assumes that the
bootloader has set the UARTBAUD bit indicating that the uarts are
running off the 14.7456MHz external crystal.

This fixes both issues. It also allows the uart clocks to be stopped
when there are no users.

Remove includes of asm/hardware.h in addition to asm/arch/hardware.h.
Then, since asm/hardware.h only exists to include asm/arch/hardware.h,
update everything to directly include asm/arch/hardware.h and remove
asm/hardware.h.

Patch from Lennert Buytenhek

Add an initial implementation of the clk_* API for the cirrus ep93xx
to the tree.  The initial implementation is somewhat minimal, with the
intention of extending it as we go along.
