i2c: gpio: support write-only sda/scl w/o pull-up

2023-01-23T22:18:54+00:00

There are slave devices that understand I2C but have read-only SDA and SCL. Examples are FD650 7-segment LED controller and its derivatives. Typical board designs don't even have a pull-up for both pins. Handle the new attributes for write-only SDA and missing pull-up on SDA/SCL. For either pin the open-drain and has-no-pullup properties are mutually-exclusive, what is documented in the DT property documentation. We don't add an extra warning here because the open-drain properties are marked deprecated anyway. Signed-off-by: Heiner Kallweit [wsa: switched to device properties] Signed-off-by: Wolfram Sang
