[PATCH 00/14] fsi: Fixes and Coldfire coprocessor offload

2018-06-26 Thread Benjamin Herrenschmidt
This series implements support for offloading the FSI protocol bitbanging to the ColdFire secondary core of the Aspeed SoCs. The result increases FSI performance by a factor of 4, and on systems that don't support async FSI clock, provide much more regular and continuous clocking which helps reliab
