* mpc85xx: Fix the offset of register address errorTang Yuantian2013-11-25-2/+2
| | | | | | | | | The offset of register address within GPIO module is just CONFIG_SYS_MPC85xx_GPIO_ADDR. So, fix it. The following platforms are confirmed: MPC8572, P1023, P1020, P1022, P2020, P4080, P5020, P5040, T4240, B4860. Signed-off-by: Tang Yuantian <Yuantian.Tang@freescale.com>

* mpc85xx: make gpio_direction_output respect valueChris Packham2012-10-22-1/+4
| | | | | | | | | | | | | | Users of familiar with the Linux gpiolib API expect that value parameter to gpio_direction_output reflects the initial state of the output pin. gpio_direction_output was always driving the output low, now it drives it high or low according to the value provided.

* mpc85xx: Add inline GPIO acessor functionsKyle Moffett2011-10-21-0/+123
To ease the implementation of other MPC85xx board ports, several common GPIO helpers are added to <asm/mpc85xx_gpio.h>. Since each of these compiles to no more than 4-5 instructions it would be very inefficient to call them out of line, therefore we put them entirely in the header file. The HWW-1U-1A board port which these were written for strongly prefers to set multiple GPIOs as a single batch operation, so the API is designed around that basis. To assist other board ports, a small set of wrappers are used which provides a standard gpio_request() interface around the MPC85xx-specific functions. This can be enabled with CONFIG_MPC85XX_GENERIC_GPIO Signed-off-by: Kyle Moffett <Kyle.D.Moffett@boeing.com> Cc: Andy Fleming <afleming@gmail.com> Cc: Peter Tyser <ptyser@xes-inc.com> Signed-off-by: Kumar Gala <galak@kernel.crashing.org>
