Some I2C bus drivers do not allow zero-length data transfers which are
required to start a measurement with the HIH6130/1 sensor. Nevertheless,
we can overcome this limitation by writing a zero dummy byte. This byte
is ignored by the sensor and was verified to be working with the OMAP
I2C bus driver in a BeagleBone board.

[Guenter Roeck: Simplified complexity of write_length initialization]

The Samsung serial driver currently does not support setting the
RTS pin with an ioctl(TIOCMSET) call. This patch adds this support.
Changes in v2:
- Preserve the RTS pin's manual setting in set_termios() also when
enabling CRTSCTS.

While upgrading the kernel on a S3C2412 based board I've noted
that it was impossible to boot the board with a 2.6.32 or upper
kernel. I've tracked down the problem to the EBI virtual memory
mapping that is in conflict with the IO mapping definition in
arch/arm/mach-s3c24xx/s3c2412.c.

While testing an ADC121S021 in an embedded board with a S3C2142 SoC (ARM
core), I have found that the 'adcxx' driver does not handle correctly
single channel ADCs from this chip family. For single channel chips you
must only issue one read transfer for correct measurement.

In a project for my company I've needed to use the watchdog device in a
PCM-5335 SBC from AAEON. The watchdog timer is from a Winbond's SuperIO
chip, the W83977F.
I've made this driver based on two others already on the kernel tree,
the w83877f_wdt and the wdt977.
