6e5a113837 a bit more -Werror compatability
for clang, fix warnings in drivers/, lib/, servers/, sys/, common/.
by turning off fatal warnings (takes effect if the default is on),
fixing warnings or reducing the warning level.

228e84ad2a i2c: general clean-up
Implement changes based on Kees comments on the code review:
	http://gerrit-minix.few.vu.nl/#/c/676/

Changes:
 - use spin API instead of micro_delay() for busy-wait loops.
 - use read16/write16/set16 from mmio.h to access I2C registers.
 - reduce the timeout for soft reset.
 - in read/write, don't mix variable declaration and initialization.
 - after transfer, wait for access ready instead of blindly delaying.
 - rename constants am335x, dm37xx to AM335X_I2C_BUS, DM37XX_I2C_BUS.
 - rename ADDRESS_MASK to MAX_I2C_SA_MASK for clairity.
 - rename omap_i2c_claim_bus() to omap_i2c_bus_is_free().

6405d78182 readclock/tda19988: fix compiler/cppcheck warnings
readclock:
 - the setup function for readclock on i386 was missing a return.
 - the message field for RTCDEV_GRANT wasn't the right type.

tda19988:
 - position variable was used without being initialized.

039c8db774 readclock.drv: add support for the TPS65950 RTC
On the BeagleBoard-xM, the RTC is located on the Power Management IC
(PMIC). To keep things consistent, access to the PMIC's RTC is done
through the readclock driver. The readclock driver forwards the request
on to the TPS65950 driver which does the work of manipulating the
registers on the chip.

09db2a8c67 readclock: add support for am335x RTC
Add support for getting/setting the am335x SoC's internal real
time clock. Also, allow the power off alarm to be set.

Make readclock an "always on" driver. This is needed for setting
power-off alarms whenever the power button is pressed on the BBB.

Replace the readclock.sh script & single run driver with a
readclock program that takes the same arguments and forwards
the requests on to the always up readclock driver.

437177b028 i2c: increase BUFLEN/CMDLEN to 128, add page flag.
128 byte reads are much more common than 32 byte reads. The message
passing + setup/teardown for a read is much more expensive, in terms
of time, than the reading itself. A slightly bigger struct is well
worth the time savings. This reduces read times for /dev/eeprom
from 57 seconds per 4KB to 14 seconds.

Additionally, make sending the page address in the eeprom driver
and utility optional. This can save a little time when reading
within the same page and allows support for smaller devices that
don't support pages (example: chips containing EDID).

061fed753e arm:mmc driver refactor and timeout fix for BeagleBoneBlack.
When we send MMC commads that contain data the controller provides no
description of the order of events and we need to be able to send data
from and to the controller "when needed". Changed the code to react
on buffer read and buffer write ready based on interrupts.

	  reads it
	. increase tx & rx fifo trigger levels -> reduces the number
	  of interrupts necessary
	. bigger rx/tx buffers

	. mask off other bits when testing bits in the status register
	. this fixes rs232 output that would otherwise never get re-triggered
	  as too many bits were set in the status byte to match the
	  possibilities.

. add receive hooks in the kernel to print asynchronously

	. add _sendcall() that extract-mfield.sh can then reliably recognize
	  the fields for messages that are sent with just send()
	. add DEBUG_DUMPIPC_NAMES to restrict printed messages to
	  from/to given process names

037aeb5a13 arm:rs232 fix.
The kernel API for requesting interrupts and the associated callback
have a somewhat strange behaviour. Requesting an interrupts is done
by calling sys_irqsetpolicy using an interrupt and a given id. This
id can be modified by the sys_irqsetpolicy and must be used for
subsequent calls to sys_irqenable/sys_irqdisable. However upon an
incoming call from the kernel NOTIFY_ARG contains the original value
encoded in a set e.g. if  1 << id == true the interrupt was raised.
