This is a patch series from Shawn Guo that moves from individual
late_initcalls() to using a member in the machine structure to invoke
a platform's late initcalls.
This cleanup is a step in the move towards multiplatform kernels since
it would reduce the need to check for compatible platforms in each and
every initcall.

This patch works with the following three flags from two headers (nand.h
and bbm.h):
(1) NAND_USE_FLASH_BBT (nand.h)
(2) NAND_USE_FLASH_BBT_NO_OOB (nand.h)
(3) NAND_BBT_NO_OOB (bbm.h)
These flags are all related and interdependent, yet they were in
different headers. Flag (2) is simply the combination of (1) and (3) and
can be eliminated.
This patch accomplishes the following:
* eliminate NAND_USE_FLASH_BBT_NO_OOB (i.e., flag (2))
* move NAND_USE_FLASH_BBT (i.e., flag (1)) to bbm.h
It's important to note that because (1) and (3) are now both found in
bbm.h, they should NOT be used in the "nand_chip.options" field.
I removed a small section from the mtdnand DocBook because it referes to
NAND_USE_FLASH_BBT in nand.h, which has been moved to bbm.h.

DA850/OMAP-L138 EMAC driver uses random mac address instead of
a fixed one because the mac address is not stuffed into EMAC
platform data.
This patch provides a function which reads the mac address
stored in SPI flash (registered as MTD device) and populates the
EMAC platform data. The function which reads the mac address is
registered as a callback which gets called upon addition of MTD
device.
NOTE: In case the MAC address stored in SPI flash is erased, follow
the instructions at [1] to restore it.

c. Passed the da850evm_spi_notifier structure to register_mtd_user()

Apart from the regular AM18x/DA850/OMAP-L138 SoC operating
at 300MHz, these SoCs have variants that can operate at a
maximum of 456MHz. Variants at 408Mhz and 375 Mhz are available
as well.
Not all silicon is qualified to run at higher speeds and
unfortunately the maximum speed the chip can support can only
be determined from the label on the package (not software
readable).
The EVM hardware for all these variants is the same (except
for the actual SoC populated).
U-Boot on the EVM sets up ATAG_REVISION to inform the OS
regarding the speed grade supported by the silicon. We use
this information to pass on the speed grade information to

This patch adds a pca953x platform device for the tca6416 found on the evm
baseboard. The tca6416 is a GPIO expander, also found on the UI board at a
separate I2C address. The pins of the baseboard IO expander are connected to
software reset, deep sleep enable, test points, a push button, DIP switches and
LEDs.
Add support for the push button, DIP switches and LEDs and test points (as
free GPIOs). The reset and deep sleep enable connections are reserved by the
setup routine so that userspace can't toggle those lines.
The existing tca6416-keypad driver was not employed because there was no
apararent way to register the LEDs connected to gpio's on the tca6416 while
simultaneously registering the tca6416-keypad instance.

This patch adds EV_KEYs for each of the 8 pushbuttons on the UI board via a
gpio-key device.
The expander is a tca6416; it controls the SEL_{A,B,C} lines which enable and
disable the peripherals found on the UI board in addition to the 8 pushbuttons
mentioned above. The reason the existing tca6416-keypad driver is not employed
is because there was no aparent way to keep the gpio lines used as
SEL_{A,B,C} registered while simultaneously registering the pushbuttons as a
tca6416-keypad instance.
Some experimentation with the polling interval was performed; we were searching
for the largest polling interval that did not affect the feel of the
responsiveness of the buttons. It is very subjective but 200ms seems to be a
good value that accepts firm pushes but rejects very light ones. The key values
assigned to the buttons were arbitrarily chosen to be F1-F8.

The CPGMAC pin list in da850.c was incorrectly split into two MII/RMII mode
specific pin lists, while what pin group is used is a function of how the board
is wired. Copy the pin lists to board-da850-evm.c, renaming them accordingly,
and merge the two lists in da850.c into one, da850_cpgmac_pins[], representing
the CPGMAC module as a whole...

The Sitara AM18x SoCs from TI are an OMAP-L138 pin-to-pin

More information about these processors available at:
www.ti.com/am1x
Because of their compatibiliy with OMAP-L1x, the kernel
support for OMAP-L1x is fully relevant to AM1x processors.
This patch updates the Kconfig prompt and help text to include
the AM1x part names to help users select configurations required
for these parts easily.
Also, the hardware information that shows up in /proc/cpuinfo
is updated to show applicability of the respective OMAP-L1x EVMs

Currently the EDMA queue to be used by for servicing ASP through
internal RAM is fixed to EDMAQ_0 and that to service internal RAM
from external RAM is fixed to EDMAQ_1.
This may not be the desirable configuration on all platforms. For
example, on DM365, queue 0 has large fifo size and is more suitable
for video transfers. Having audio and video transfers on the same
queue may lead to starvation on audio side.
platform data as defined currently passes a queue number to the driver
but that remains unused inside the driver.
Fix this by defining one queue each for ASP and RAM transfers in the
platform data and using it inside the driver.
Since EDMAQ_0 maps to 0, thats the queue that will be used if
the asp queue number is not initialized. None of the platforms
currently utilize ping-pong transfers through internal RAM so that
functionality remains unchanged too.
This patch has been tested on DM644x and OMAP-L138 EVMs.

Host map configuration instructs the interrupt controller to route interrupt
channels to FIQ or IRQ lines. Currently, DA8xx family of devices leave these
registers at their reset-default values.
TNETV107X however does not have sane reset defaults, and therefore this
architecture needs to reconfigure the host-map such that channels 0 and 1
go to FIQ, and the remaining channels raise IRQs.
This patch adds an optional host map argument to cp_intc_init() for this.

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.
