GPIO0 and GPIO1 are linked to unique interrupt line in PXA series,
others are linked to another interrupt line. All GPIO are linked to one
interrupt line in MMP series.
Since gpio driver is shared between PXA series and MMP series, define
GPIO0 and GPIO1 as chained interrupt chip. So we can move out gpio code
from irq.c to gpio-pxa.c.

Avoid to define gpio_to_irq() and irq_to_gpio() for potential name
confliction since multiple architecture will be built together.

From: Haojian Zhuang @ 2011-10-11 13:17 UTC (permalink / raw)
To: linux-arm-kernel
NR_BUILTIN_GPIO is both defined in arch-pxa and arch-mmp. Now replace it
with PXA_NR_BUILTIN_GPIO and MMP_NR_BUILTIN_GPIO.

This seems like a fully valid merge of common pxa GPIO include
files. And I guess if both are not using plat-pxa it cannot reside
in <plat/gpio-pxa.h>?
Grant: shall this be <linux/gpio-pxa.h> or <linux/gpio/pxa.h> or so?
Yours,

Hmm, more fundamentally, does this even need to be a header file?
Most of the header file looks like it should not be visible in the entire
kernel, so better move as much as possible into the gpio-pxa.c file.
I'm not sure how much remains in the end, but that should probably
determine the location (drivers/gpio/gpio-pxa.h, asm/gpio-pxa.h
or linux/gpio-pxa.h). In general, everything should be as local
as possible.
One more thing regarding the contents of the header:

When these get moved into the driver itself, it's probably a good
idea to turn these into proper accessors, something like
enum pxa_gpio_reg {
GPLR,
GPDR,
GPSR,
GPCR,
GRER,
GFER,
GEDR,
};
static void __iomem *pxa_gpio_reg_base;
static inline u32 pxa_gpio_read(unsigned int bank, enum pxa_gpio_reg reg)
{
unsigned offset = (bank < 3) ? bank << 2 : 0x100 + ((bank - 3) << 2);
return readl_relaxed(pxa_gpio_reg_base + offset + 12 * reg);
}
static inline void pxa_gpio_write(unsigned int bank, unsigned int reg, u32 val)
{
unsigned offset = (bank < 3) ? bank << 2 : 0x100 + ((bank - 3) << 2);
return writel_relaxed(val, pxa_gpio_reg_base + offset + 12 * reg);
}
That should let you get rid of most of the macros and the incorrect
'volatile' access.

To: linux-arm-kernel
Support clk in gpio driver. There's no gpio clock in PXA25x and PXA27x.
So use dummy clk instead. And move the gpio edge initialization into
gpio driver for arch-mmp.
