Now in TI OMAP GPIO driver there are a lot of places where
System GPIO number calculated and then converted to GPIO offset.
What is worse is that in many place such conversation performed twice
or even three times. But actually, we don't need to do that at all, 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
Hence, it is safe to convert all GPIO OMAP functions to use GPIO
offset instead of system GPIO numbers. Also, this allows to remove
unneeded conversations routines
#define GPIO_INDEX(bank, gpio)
#define GPIO_BIT(bank, gpio)
int omap_irq_to_gpio()
Tested on:
- dra7-evm.
- omap1 (osk5912), 770 and E3.
Last two patches have to be tested on OMAP1:
- gpio: omap: get rid of omap_irq_to_gpio()
- gpio: omap: get rid of GPIO_INDEX() macro
Based on top of Linux 4.0-rc4 plus patch
'[PATCH 1/2] gpio: omap: irq_shutdown: remove unnecessary call of
gpiochip_unlock_as_irq'
http://www.spinics.net/lists/linux-omap/msg116482.html
Changes in v2:
- fixed build failure with Patch 5, no functional code
changes.
