From: Wayne Chang <waynec@xxxxxxxxxx> Add the device-tree binding documentation for Cypress cypd4226 dual Type-C controller. Signed-off-by: Wayne Chang <waynec@xxxxxxxxxx> Signed-off-by: Jon Hunter <jonathanh@xxxxxxxxxx> --- V9: added 'unevaluatedProperties' and 'additionalProperties' V8: removed 'additionalProperties' V7: updated example to use 'typec' for the node name V6: no changes V5: updated subject and updated binding to use 'firmware-name'. V4: no changes V3: fix additionalProperties warning on new schema V2: based on the review comments.
