I2C Expansion Board
#37
For interrupt, following the specs sheet, it was pretty easy to determine that the s_twi is 0x2c (76 in the specs, but offsetted by 32) since the s_uart is 0x26 (70 in specs) (except if the previous offsetting is wrong), maybe I should try to get rid of this offset which I don't know where it is coming from.
Problem can also be from clock and reset, which are not using apb0_gates/apb0_reset like other sunxi such H3 where the I2C on i2c@01f02400 is working.
I hate this PineA64 DTS since it is coming from a decompiled version from AllWinner and doesn't follow rules used in Mainline, where apb0_gates/apb0_reset doesn't even exist.

EDIT: I've checked the interrupt on H3, and it is really 0x2C (76 with offset of 32). Som it must be something else, the clock or the reset.
