K1 or K3? Aside from this K1-related patch, the rest of the series focuses on adding = support for the K3 SoC. I included the K1 header because I noticed it was missing in th= e upstream tree while working on the K3 support. It seems my attempt to 'clean up' K1 while adding K3 has caused unnecessary= confusion. Would you prefer me to remove the K1 patch from this series and submit it a= s a separate patch? - Troy
