Using a device_initcall() for initializing the voltage regulator
on DA850 is not such a good idea because it gets called for all
platforms - even those who do not have a regulator implemented.
This leads to a big fat warning message during boot-up when
regulator cannot be found.
Instead, tie initialization of voltage regulator to cpufreq init.
Define a platform specific init call which in case of DA850 gets
used for initializing the regulator. On other future platforms it
can be used for other purposes.

The patch adds support for DaVinci cpu idle driver.
Two idle states are defined:
1. Wait for interrupt
2. Wait for interrupt and DDR self-refresh (or power down)
Some DaVinci SoCs support putting DDR in self-refresh (eg Dm644x, DM6467)
while others support putting DDR in self-refresh and power down (eg DM35x,
DA8xx).
Putting DDR (or mDDR) in power down saves more power than self-refresh.
The patch has been tested on DA850/OMAP-L138 EVM.

DA850/OMAP-L138 EVM has a RMII Ethernet PHY on the UI daughter card. The PHY
is enabled by proper programming of the IO Expander (TCA6416) ports. Also for
RMII PHY to work, the MDIO clock of MII PHY has to be disabled since both the
PHYs have the same address. This is done via the GPIO2[6] pin. This patch adds
support for RMII PHY.
This patch also adds a menuconfig option to select one or no peripheral
connected to expander. Currently, sub-options in this menu are RMII and no
peripheral.This menuconfig option is similar to the one present for UI card on
DA830/OMAP-L137 EVM.

Adds basic frequency scaling support for DA850/OMAP-L138.
Currently, frequency scaling only on PLL0 is supported. No scaling of PLL1
as yet.
Peripherals like MMC/SD which have a clock input synchronous with
ARM clock will not work well since the clock will change behind their backs.
Support for notification to such devices to adjust themselves to the
new frequency will be added in later patches. Current defconfigs keep
CPUFreq disabled so it will not affect normal operation.
The OPP defintions assume clock input of 24MHz to the SoC. This is inline
with hardcoding of input frequency in the <soc>.c files. At some point
this will need to move into board dependent code as new boards appear with
a different reference clock.
Tested on OMAP-L138 EVM with ondemand governer and a shell script to

This patch takes out IO mapping macros from mach/io.h and puts them in
mach/hardware.h avoiding need to include mach/io.h in various files such as
serial.h, vmalloc.h etc.
The main reason to avoid inclusion of mach/io.h is, when default in/out macros
are overridden by machine specific functions (e.g., in case of PCI I/O), they
result into linker error. An example snippet and error snapshot is listed below.
Following code in mach/io.h:
#define inl(p) my_inl()
static inline unsigned int my_inl(unsigned int addr)
{
if (IS_PCI_IO(addr))
return pci_inl ();
else
return le32_to_cpu(__raw_readl(__typesafe_io(addr)));
}
leads to error:
LD arch/arm/boot/compressed/vmlinux
arch/arm/boot/compressed/misc.o: In function `my_inl':
misc.c:(.text+0x2744): undefined reference to `pci_inl'
make[2]: *** [arch/arm/boot/compressed/vmlinux] Error 1
This is because mach/io.h gets included in arch/arm/boot/compressed/misc.c
through mach/serial.h but pci.c file, which defines 'pci_inl' doesn't get built
