It is based on the Marvell SDK with additions for various (non-gpio) pin configurations based on the datasheet. Signed-off-by: Chris Packham Reviewed-by: Andrew Lunn --- Notes: Changes in v4: - None Changes in v3: - Use mmio instead of syscon - Add additional functions based on the datasheet Changes in v2: -
