The GCC trick on optimization for AVR32
Ah, BUILD_BUG_ON is for errors that you can always detect at compile time. That's generally not going to be the case with function parameters... The optimizations you seem to...

AP7000 and unaligned access
A uint16_t is not a "word" ... a "uint32_t" would be a word. Try that with a word, not half-word. One of the numerous reasons to wish Microsoft a speedy death is that they are...

XMEGA
I've been reading the XMega-A manual, and it looks like one of the agendas with this series was to uplevel the quality of the peripherals by a big chunk. Seems like every module...

STK1000 USB Connector
Note that the long signal path from stk1002 through connectors to the stk1000 isn't healthy for signal quality, in ways that would usually matter a LOT for high speed signals....

RE: Frustrated with lack of NGW100 IO options
It's more like: an stk1003 or stk1004 will be wired up to the stk1000 in different ways, so that you need to customize the stk1002 code not the stk1000 stuff. Consider that the...

RE: Frustrated with lack of NGW100 IO options
Accessing an EEPROM, as done by drivers/spi/at25.c, should also be informative. Compare against the datasheet of something like an at25020a (256 bytes, small). The EEPROM...

Temperature Sensor and NGW100
Forum seems to have dropped my previous reply ... NGW has a built-in temperature sensor, on its "board controller" ... an ATtiny24 programed with some vaguely-PMBus-ish firmware....

Atmel SPI driver
Nothing cares specifically which SPI controller is used ... one simple example is drivers/spi/at25.c but there are others too.

Battery Backed RTC
Look at drivers/rtc/Kconfig for a list of i2c based RTCs with current support.
