Add arduino header/spi support for HSDK board #30618

Closed vanwinkeljan closed 3 years ago

vanwinkeljan commented 3 years ago

Is your enhancement proposal related to a problem? Please describe.

Currently the HSDK board has an ILI9340 display added on the arduino spi interface (hsdk spi2) which is not physically present on the board and as such a display shield should be used instead.

Problem in removing the display is that the HSDK board is missing the arduino header & spi. Adding the arduino spi is straight forward but the arduino header pinout is missing documentation.

Describe the solution you'd like

Add arduino spi and header to HSDK dts

Describe alternatives you've considered

Remove ILI9340 display from spi2 as-is

Additional context

This problem popped up while cleaning up unnecessary config overlays in the LVGL sample. In case the arduino spi and headers are supported the file samples/display/lvgl/boards/hsdk.conf can be removed.

@IRISZZW could you please check this one and see if there's a possibility to add support of that particular peripheral on the HSDK in Zephyr.

IRISZZW commented 3 years ago

we have some documents about the Arduino pins in HSDK board: HSDK doc

There are some problem to add the arduino header for HSDK, HSDK board includes a CY8C9520A I/O expander, and some of the arduino header pins use the extended I/O. But there is no CY8C9520A driver in zephyr currently.

I think this issue has been fixed by this PR: #33907. @vanwinkeljan may we close this issue?

ruuddw commented 3 years ago

Closing this one now - @vanwinkeljan feel free to reopen or open another issue if #33907 doesn't handle this issue.
