Kevin O'Connor 95eb00740b stm32: Avoid read+write modify instructions in can.c 
Prefer explicitly setting the hardware registers and avoid using C
read and modify instructions where possible.  This avoids race
conditions where an interrupt or hardware change could cause subtle
corruption of the register state.

ds18b20: new module for 1-wire temperature sensor (#3462) 
Initial commit of code to support 1-wire (Dallas) sensors such
as the DS18B20. Requires Linux kernel drivers to create a file
in /sysfs which is read by this module, and temperature
typically returned to a temperature_fan.

Decrease the number of pwm channels to a more reasonable 16. Increase

Arne Jansen a2c309a2b0 stm32: performance improvement for spi on stm32f0 
The stm32 has a small queue for spi tx/rx. The current code only uses the
spi with a single byte buffer, effectively waiting for each byte to complete
before starting the next transfer.
This patch changes the structure of spi_transfer() to make use of the queue
and achieve back-to-back transfer of bytes on spi.

Arne Jansen ce35ee45d6 stm32: fix spi_transfer for stm32f0 
The current code accesses the DR as 32 bit. This enabled data packing mode,
effectively adding a 00 byte between each sent byte. The receive side had
similar problems.
To prevent this, all accesses are 8 bit now, even though this is not
necessary on stmf[14].
