  • a5d28c8e6   powerpc/CPM: Add i2c pins to dts and board setup ... Browse Code »

    Initialize I2C pins on boards with CPM1/CPM2 controllers and document the
    i2c bus in booting-without-of.

    The boards don't have any I2C chips connected to the I2C bus, so unless
    some external chips are connected to the boards, this code is just an
    example of setting everything else up.

  • 75e89b02e   [POWERPC] arch/powerpc/platforms/82xx: Add missing of_node_put ... Browse Code »

    Of_get_parent and of_find_compatible_node do a of_node_get, and thus a
    corresponding of_code_put is needed in both the error case and the normal
    return case.

    The problem was found using the following semantic match.
