Subject: [PATCH 7/7] [WIP] pinephone-pro: Remove cargo-culted iodomain config
|
||
|
|
|
||
|
|
It is unclear what it actually does, and the TRM states this register
|
||
|
|
should already be at `0x1` on reset.
|
||
|
|
|
||
|
|
Thus it is assumed this would be redundant. Except that it is not, and
|
||
|
|
keeping this change in will break SPI NOR Flash support. The SPI bus(?)
|
||
|
|
will be tied up, I assume, and thus return `ff ff ff` as an identifier
