Changes since version 1: - Add nuvoton,sys-mgr property in NPCM devicetree. - Describe the commit message in imperative mood. - Modify the description in i2c binding document to cover NPCM series. - Add new property in i2c binding document. - Create a new patch for client address calculation. - Create a new patch for updating gcr property name. - Create a new patch for removing unused clock node. - Explain EOB in the commit description. - Create a new patch for correcting NPCM register access width. - Remove some comment since the corresponding logic no longer exists. - Remove fixes tag while the patch adds an additional feature. - Use devicetree data field to support NPCM845.
