[PATCH v3 0/7] usb: typec: ucsi: Remaining changes for v5.2

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



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:

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].

Let us know if you want anything to be changed.

thanks,
