Hi Greg, This is the third version of this collection of UCSI driver related changes. I fixed the header problem I caused in Ajay's patch adding the NVIDIA alt mode support (patch 7/7), and I also took the liberty of writing the missing ABI documentation for the extra sysfs file that's created in the driver for Cypress CCGx Type-C controller (ucsi_ccg.c). v2 cover letter This is the second version of this series. The sparse warning, that was the only issue with the first version, is now fixed. The fix was made by adding the first patch ("i2c: nvidia-gpu: Supply CCGx driver the fw build info"). It add a device property for the CCGx device that the CCGx driver can use to identify the required firmware build. I also decided to include two extra patches from Ajay where NVIDIA probing driver is added for the DisplayPort alternate mode: https://www.spinics.net/lists/linux-usb/msg178847.html v1 cover letter: Here are the remaining patches from me and Ajay for the UCSI driver. I took the liberty of collecting them for you, and resending everything together. There are two patches from Ajay adding support for firmware upgrading with the Cypress CCGx controllers [1], and two patches from me enabling DisplayPort alt mode with the UCSI driver [2].
