Hi Charles,
I have one comment.
I think current extcon-arizona.c has the many platform data
so, extcon-arizona.c use the too much if statement to support each feature
for different wolfsonmicro codec. I think it cause the complicated code.
For example,
You may use 'struct of_device_id' as following. You used already this method
on drivers/mfd/arizona-core.c. If you separate the function of each wmXXXX arizona,
it makes improved readability for extcon-arizona.c and some user will use extcon-arizora
more easily.
struct arizona_extcon_data {
void (*init)(...);
void (*irq_handler)(...);
...
};
struct arizona_extcon_data wm8994_data {
.init = wm8994_extcon_init,
.irq_handler = wm8994_extcon_irq_handler;
...
};
static const struct of_device_id arizona_extcon_dt_match[] = {
{
.compatible = "wm8994-arizona-extcon",
.data = (void *)wm8994_data;
}, {
.compatible = "wmXXXX-arizona-extcon",
.data = (void *)wmXXXX_data;
},
};
I expect that you will revise the arizona-extcon.c driver on next time.
Thanks,
Chanwoo Choi
