Laurent MEUNIER 18abfdb604 STM32: gpio: style consistency 2017-02-16 19:34:08 +01:00
Laurent MEUNIER dce2ca75d8 STM32: gpio few performance improvements 
Those are minor changes to increase performance of widely used
GPIO functions.

Laurent MEUNIER 3517eb108e STM32: Change Set_GPIO_Clock return type 
Directly return a GPIO_TypeDef pointer to avoid extra casts.
Also move it to GPIO file.

Laurent MEUNIER 57e0225248 STM32: gpio: factorize gpio_api.c and gpio_object.h 
Let's make the code more common for gpios.

The only difference between STM32 families is that BRR register may
not be available. In case BRR is not available, we use the 16 left bits
of BSRR instead. We could always use BSRR, but BRR saves one left-shift
operation, so let's use it when available.

By default we will consider using BRR, except for platforms that define
GPIO_IP_WITHOUT_BRR.
