SAM3/4 GPIO: Enable peripheral clock for GPIO port when GPIO is configured as input.
...
The value of a GPIO input is only sampled when the peripheral clock for
the port controller the GPIO resides in is enabled. Therefore we need
to enable the clock even when polling a GPIO.

A consequence of Max's change to the logic to enable access to the backup domain is that every call to enabledbkp(true) must be followed by a matching call to enablebkp(false). There was one cse in both RTCC drivers where that may not always be true.

STM32 and EFM32 SPI drivers adopted an incompatible conventions somewhere along the line. The set the number of bits to negative when calling SPI_SETBITS which had the magical side-effect of setting LSB first order of bit transmission. This is not only a hokey way to pass control information but is supported by no other SPI drivers.
...
This change three things: (1) It adds HWFEAT_LSBFIRST as a new H/W feature. (2) It changes the implementations of SPI_SETBITS in the STM32 and EFM32 derivers so that negated bit numbers are simply errors and it adds the SPI_HWFEATURES method that can set the LSB bit order, and (3) It changes all calls with negative number of bits from all drivers: The number of bits is now always positive and SPI_HWFEATUREs is called with HWFEAT_LSBFIRST to set the bit order.
