Convert GPIO IRQ functions to use GPIO offset instead of system
GPIO numbers. This allows to drop unneeded conversations between
system GPIO <-> GPIO offset which are done in many places and
many times.
It is safe to do now because:
- gpiolib always passes GPIO offset to GPIO controller
- OMAP GPIO driver converted to use IRQ domain, so
struct irq_data->hwirq contains GPIO offset
This is preparation step before removing:
#define GPIO_INDEX(bank, gpio)
#define GPIO_BIT(bank, gpio)
int omap_irq_to_gpio()
...
static void omap_gpio_unmask_irq(struct irq_data *d)
{
struct gpio_bank *bank = omap_irq_data_get_bank(d);
- unsigned int gpio = omap_irq_to_gpio(bank, d->hwirq);
+ unsigned offset = d->hwirq;
unsigned int irq_mask = GPIO_BIT(bank, gpio);
u32 trigger = irqd_get_trigger_type(d);
unsigned long flags;
This series up to this patch produces a build error that
would break git bisect:
drivers/gpio/gpio-omap.c: In function ‘omap_gpio_unmask_irq’:
drivers/gpio/gpio-omap.c:866:37: error: ‘gpio’ undeclared (first use in this function)
unsigned int irq_mask = GPIO_BIT(bank, gpio);
Oh. Thanks for catching that :) - splitting/rebasing issue.
