Rename the PR, it's improving driver support but not implementing enhanced SPI operation. I think you could drop the first commit about rx-delay, see #87427 (if you have input on such improvements, please do) |
yep that indeed appear to be the same api, i will drop that patch and review it later for compatibility, but a surface level check appears to be exactly what we need. |
The DFS(Data Frame Size) is at CTRLR0[4:0] in HSSI controller. Signed-off-by: Younghyun Park <[email protected]>
The TXFTLR register has 2 major fields which are TFT for triggering interrupt threshold and TXFTLR for starting transfer threshold. This is to ensure that sufficient data is ready for starting transfer. Signed-off-by: Younghyun Park <[email protected]>
Read the Synopsys SSI component version to extend supported capability based on the version. Signed-off-by: Younghyun Park <[email protected]>
@tbursztyka mind if i get a re-review? |
This is a re-attempt of #77492 minus the API modification patches that will be modified and sent in a formal change later outside of the driver specific changes.
