I think that slipped my check list unfortunately. :( But then, if we
think that it is just n900 that is impacted, then I wonder if we can
override the alias? just wondering..
That https://lkml.org/lkml/2014/6/1/49 patch will allow such override, I
tested it on N900 with Fremantle and it works fine. Ofc I had to add
aliases {
i2c1 = &i2c1;
i2c2 = &i2c2;
i2c3 = &i2c3;
};
to omap3-n900.dts (while keeping omap3.dtsi intact) for it to work.
I checked in some Nemo N9/N950 adaptation kernel and it seems those will
be broken too(and I bet it is the same in stock Nokia N9/50 kernels):
static void __init rm680_i2c_init(void)
{
omap3_pmic_get_config(&rm680_twl_data, TWL_COMMON_PDATA_USB,
TWL_COMMON_REGULATOR_VDAC |
TWL_COMMON_REGULATOR_VPLL2);
omap_pmic_init(1, 2900, "twl5031", INT_34XX_SYS_NIRQ, &rm680_twl_data);
omap_register_i2c_bus(2, 400, rm696_peripherals_i2c_board_info_2,
ARRAY_SIZE(rm696_peripherals_i2c_board_info_2));
omap_register_i2c_bus(3, 400, rm696_peripherals_i2c_board_info_3,
ARRAY_SIZE(rm696_peripherals_i2c_board_info_3));
}
Again 1,2 and 3 for bus indexes just like on N900.
Anyway, I am fine with the alias override. If the patch makes it to the
upstream :)
Regards,
Ivo
