This patch series cleans up and simplifies the parameter handling in the dwc2 driver so that it is easier to set these parameters and easier to maintain the driver and support more platforms in the long run.
The long-term goal is to remove all static and legacy parameters in favor of autodetection and/or devicetree properties. However, this patch series is mostly a cleanup and refactoring to allow for this. Then, it adds the current gadget-specific properties. And for host-mode, it adds the DMA property. Lastly, it adds the ability to set properties from the PCI driver so that we can perform IP validation with the HAPS platform. Later patch series will address the other properties and also allow for them to be set by the PCI driver via debugfs. Tested on DWC_hsotg IP version 3.30a on Synopsys HAPS platform. v2: * Renamed host-dma to "snps,host-dma-disable". * Removed params->host_dma from being set statically. * Reverted descriptor dma params renaming (to be addressed in the future). * Simplified and removed unused code.
