The probe method of this driver, on the other hand, performs several
allocations and the error messages you intend to remove conveniently
pinpoint which one failed. While the offsets in the trace could be
used to derive the same information, I am skeptical that is enough to
justify removing the messages.

The board schematic states that the "SD_CARD_DET_N gets pulled to GND
when card is inserted" so the polarity has been updated to active low.
Polarity is now specified with a GPIO define instead of a magic number.

in the device tree. Update the documentation to reflect both ways.

This series adds support for the Kona I2C bus found on Broadcom mobile
SoCs like the bcm11351 (aka bcm281xx) and enables it on the bcm28155-ap
board.
It depends upon the following commit:

Documentation: dt: Add
Introduce support for Broadcom Serial Controller (BSC) I2C bus found
in the Kona family of Mobile SoCs. FIFO hardware is utilized but only
standard mode (100kHz), fast mode (400kHz), and fast mode plus (1MHz)
bus speeds are supported.
