There - * are two cases we need to deal with here, they cover all currently - * available ColdFire GPIO hardware. There are of course minor differences - * in the layout and number of bits in each ColdFire part, but the macros - * take all that in. + * The Freescale Coldfire family is quite varied in how they implement GPIO. + * Some parts have 8 bit ports, some have 16bit and some have 32bit; some have + * only one port, others have multiple ports; some have a single data latch + * for both input and output, others have a separate pin data register to read + * input; some require a read-modify-write access to change an output, others + * have set and clear registers for some of the outputs; Some have all the + * GPIOs in a single control area, others have some GPIOs implemented in + * different modules. * - * Firstly is the conventional GPIO registers where we toggle individual - * bits in a register, preserving the other bits in the register. For - * lack of a better term I have called this the slow method. + * This implementation attempts accommodate the differences while presenting + * a generic interface that will optimize to as few instructions as possible. + */ +#if defined(CONFIG_M5206) || defined(CONFIG_M5206e) || \ + defined(CONFIG_M520x) || defined(CONFIG_M523x) || \ + defined(CONFIG_M527x) || defined(CONFIG_M528x) || \ + defined(CONFIG_M532x) || defined(CONFIG_M54xx) || \ + defined(CONFIG_M5441x) + +/* These parts have GPIO organized by 8 bit ports */ + +#define MCFGPIO_PORTTYPE u8 +#define MCFGPIO_PORTSIZE 8 +#define mcfgpio_read(port) __raw_readb(port) +#define mcfgpio_write(data, port) __raw_writeb(data, port) + +#elif defined(CONFIG_M5307) || defined(CONFIG_M5407) || defined(CONFIG_M5272) + +/* These parts have GPIO organized by 16 bit ports */ + +#define MCFGPIO_PORTTYPE u16 +#define MCFGPIO_PORTSIZE 16 +#define mcfgpio_read(port) __raw_readw(port) +#define mcfgpio_write(data, port) __raw_writew(data, port) + +#elif defined(CONFIG_M5249) || defined(CONFIG_M525x) + +/* These parts have GPIO organized by 32 bit ports */ + +#define MCFGPIO_PORTTYPE u32 +#define MCFGPIO_PORTSIZE 32 +#define mcfgpio_read(port) __raw_readl(port) +#define mcfgpio_write(data, port) __raw_writel(data, port) + +#endif + +#define mcfgpio_bit(gpio) (1 << ((gpio) % MCFGPIO_PORTSIZE)) +#define mcfgpio_port(gpio) ((gpio) / MCFGPIO_PORTSIZE) + +#if defined(CONFIG_M520x) || defined(CONFIG_M523x) || \ + defined(CONFIG_M527x) || defined(CONFIG_M528x) || \ + defined(CONFIG_M532x) || defined(CONFIG_M5441x) +/* + * These parts have an 'Edge' Port module (external interrupt/GPIO) which uses + * read-modify-write to change an output and a GPIO module which has separate + * set/clr registers to directly change outputs with a single write access. + */ +#if defined(CONFIG_M528x) +/* + * The 528x also has GPIOs in other modules (GPT, QADC) which use + * read-modify-write as well as those controlled by the EPORT and GPIO modules. */ -#define MCFGPS(mlabel, mbase, mngpio, mpddr, mpodr, mppdr) \ - { \ - .gpio_chip = { \ - .label = #mlabel, \ - .request = mcf_gpio_request, \ - .free = mcf_gpio_free, \ - .direction_input = mcf_gpio_direction_input, \ - .direction_output = mcf_gpio_direction_output,\ - .get = mcf_gpio_get_value, \ - .set = mcf_gpio_set_value, \ - .base = mbase, \ - .ngpio = mngpio, \ - }, \ - .pddr = (void __iomem *) mpddr, \ - .podr = (void __iomem *) mpodr, \ - .ppdr = (void __iomem *) mppdr, \ - } +#define MCFGPIO_SCR_START 40 +#elif defined(CONFIGM5441x) +/* The m5441x EPORT doesn't have its own GPIO port, uses PORT C */ +#define MCFGPIO_SCR_START 0 +#else +#define MCFGPIO_SCR_START 8 +#endif +#define MCFGPIO_SETR_PORT(gpio) (MCFGPIO_SETR + \ + mcfgpio_port(gpio - MCFGPIO_SCR_START)) + +#define MCFGPIO_CLRR_PORT(gpio) (MCFGPIO_CLRR + \ + mcfgpio_port(gpio - MCFGPIO_SCR_START)) +#else + +#define MCFGPIO_SCR_START MCFGPIO_PIN_MAX +/* with MCFGPIO_SCR == MCFGPIO_PIN_MAX, these will be optimized away */ +#define MCFGPIO_SETR_PORT(gpio) 0 +#define MCFGPIO_CLRR_PORT(gpio) 0 + +#endif /* - * Secondly is the faster case, where we have set and clear registers - * that allow us to set or clear a bit with a single write, not having - * to worry about preserving other bits. + * Coldfire specific helper functions */ -#define MCFGPF(mlabel, mbase, mngpio) \ - { \ - .gpio_chip = { \ - .label = #mlabel, \ - .request = mcf_gpio_request, \ - .free = mcf_gpio_free, \ - .direction_input = mcf_gpio_direction_input, \ - .direction_output = mcf_gpio_direction_output,\ - .get = mcf_gpio_get_value, \ - .set = mcf_gpio_set_value_fast, \ - .base = mbase, \ - .ngpio = mngpio, \ - }, \ - .pddr = (void __iomem *) MCFGPIO_PDDR_##mlabel, \ - .podr = (void __iomem *) MCFGPIO_PODR_##mlabel, \ - .ppdr = (void __iomem *) MCFGPIO_PPDSDR_##mlabel, \ - .setr = (void __iomem *) MCFGPIO_PPDSDR_##mlabel, \ - .clrr = (void __iomem *) MCFGPIO_PCLRR_##mlabel, \ - } +/* return the port pin data register for a gpio */ +static inline u32 __mcfgpio_ppdr(unsigned gpio) +{ +#if defined(CONFIG_M5206) || defined(CONFIG_M5206e) || \ + defined(CONFIG_M5307) || defined(CONFIG_M5407) + return MCFSIM_PADAT;
