Thank you for contacting Intel Embedded Community.
In order to be on the same page, could you please let us know if the affected design has been developed by you or by a third-party manufacturer? In case that it is a third-party device , please give the model, part number , and where is stated its documentation.
Waiting for your answer.
Thank you for your reply.
we are a third party manufacturer but my Q was all about on CPU GPIO driver.
since the GPIO HW is build in the chip set we would like to use a standard driver that can work on D-1559 processor.
there were no changes on host regarding this device.
Thanks for your clarification.
You should implement the requested driver using the information stated in section 3.14 - General Purpose I/O (D31: F0), on pages 116 to 120 of the Intel(R) Xeon(R) Processor D-1500 Product Family External Design Specification [EDS] Volume 5 of 5: Integrated Platform Controller Hub document # 544044. Also as a reference, the information stated in the Intel(R) Serial IO Bus Drivers Product Requirements Document [PRD] document # 571354 may help.
