ARM: at91: fix nommu build regression
The newly introduced support for SAMA5D4 added access to the
'AT91_ALT_BASE_SYS' register area, but failed to define the
symbols in the case when CONFIG_MMU is disabled.
We really should not hardwire addresses like this any more,
but as a small fixup, this patch just adds the missing
definitions for the nommu case, which gets at91x40_defconfig
and any configuration of sam9 and sama5 with MMU disabled
back to work.

requested clocks, which are descended of the main PLL's (e.g.
pll1_pfd1, which provides the system clock).
To archive the full 500MHz system clock, DDR clock need to be a
descendant of PLL2 rather than PLL1 (DDRC_CLK_SEL set to 0). The
bootloader sets up the clocks accordingly before making use of
DDR at all. However, in Linux, there is no driver using PLL2,

ARM: i.MX6: add more chip revision support
Add more revision support for the new i.MX6DQ tape-out (TO1.5). This
TO1.5 is the Rev 1.3 as documented in i.MX6DQ data sheet, because TO1.3
and TO1.4 are never revealed.

ARM: OMAP5+: Reuse OMAP4 PM code for OMAP5 and DRA7
OMAP4, OMAP5 and DRA7 share a lot of common logic and data structures.
These have been enabled in the previous patches, however, this also
means that OMAP5 or DRA7 only builds also need to build OMAP4 logic.
Update to reuse OMAP4 logic.
This fixes the 'undefined reference to 'omap4_pm_init_early'' in
OMAP5 or DRA7 only builds.

ARM: shmobile: r8a7740: Use SoC-specific 48-bit CMT compat string
In general Renesas hardware is not documented to the extent
where the relationship between IP blocks on different SoCs can be assumed
although they may appear to operate the same way. Furthermore the
documentation typically does not specify a version for individual
IP blocks. For these reasons a convention of using the SoC name in place
of a version and providing SoC-specific compat strings has been adopted.
Although not universally liked this convention is used in the bindings for
a number of drivers for Renesas hardware. The purpose of this patch is to
make use of the SoC-specific CMT compat string for the r8a7740 48-bit CMT
