iMX51: introduce IMX_GPIO_NR
Currently, to define a GPIO number, we're using something like : #define EFIKAMX_PCBID0 (2*32 + 16) to define GPIO 3 16. This is not really readable and it's error prone imho (note the 3 vs 2). So, I'm introducing a new macro to define this in a better way. Now, the code sample become : #define EFIKAMX_PCBID0 IMX_GPIO_NR(3, 16) v2: - move to gpio.h - add parens & spaces - switch to IMX_GPIO_NR instead of MX51_GPIO_NR Signed-off-by: Arnaud Patard <arnaud.patard@rtp-net.org> Cc: Amit Kucheria <amit.kucheria@linaro.org> Cc: Sascha Hauer <s.hauer@pengutronix.de> Cc: Eric BĂ©nard <eric@eukrea.com> Signed-off-by: Sascha Hauer <s.hauer@pengutronix.de>
