Quite a bit of fallout all over the place, nothing terribly exciting.

Paul Mundt 7912825d8b sh: Tidy up pre-clkdev clk_get() error handling.
clk_get() used to return NULL or an errno value depending on whether a
clkdev lookup failed or a clock wasn't found in the primary clock list.
As these disjoint paths were unified and everything now is handled via
clkdev lookups, the NULL case never makes it out of clk_get(). Update
accordingly and always look to the errno value.

Paul Mundt d57d64080d sh: Prevent 64-bit pgprot clobbering across ioremap implementations.
Presently 'flags' gets passed around a lot between the various ioremap
helpers and implementations, which is only 32-bits. In the X2TLB case
we use 64-bit pgprots which presently results in the upper 32bits being
chopped off (which handily include our read/write/exec permissions).

As such, we convert everything internally to using pgprot_t directly and
simply convert over with pgprot_val() where needed. With this in place,
transparent fixmap utilization for early ioremap works as expected.

Matt Fleming 6f82b6ebb1 sh: Use ioremap_fixmed to map the SM501 DRAM config register
We need to write to the DRAM config register very early and at such an
early stage ioremap() is not available. So use ioremap_fixed() to map
the register.

The reason that we are avoiding using the legacy P2 mapping is that
there will come a day when the legacy P2 mappings no longer exist.

Paul Mundt a09d2831b3 sh: heartbeat: Update boards for access size hinting.
This updates the existing boards that specify the register width through
platform data to use the resource flags instead. This eliminates platform
data completely in most cases, and permits further improvement in the
heartbeat driver as well as shrinking the overall private data size.

Magnus Damm 0d4fdbb64f sh: rework mode pin code
This patch reworks the mode pin code to keep the pin
definitions in one place. The mode pins values are now
the value of the bit instead of bit number.

With this patch in place the sh7785 header file contains
mode pin comments. The sh7785 clock code and the sh7785lcr
board code are updated to reflect the new shared mode pins.

Magnus Damm 63d12e2323 sh: sh7785lcr mode pin configuration
This patch adds mode pin support to the sh7785lcr board.

The harware allows the user to control the mode pins using
dip switches S1 and S2, but from the software the pins are
fixed to the factory default since we have no way to reading
out this configuration from software.

Paul Mundt a77b5ac0ea sh: clkfwk: Update SH7785 for refactored clock framework.
This updates the SH7785 CPU code as well as the SH7785LCR board support
code for making use of the newly refactored clock framework. Support for
the legacy CPG clocks is dropped at this point, with the extal frequency
fed in from the board code.

Magnus Damm 600fa578a9 sh: improve sh7785lcr power off code
Improve the sh7785lcr power off implementation to
never return. It takes some time before the board
is actually powered off, just hang after asking
the harware to power down.

This removes the serial port garbage printout.
