[PATCH/RFC,0/3] Remove KZM9D board staging support

Message

Geert Uytterhoeven June 9, 2023, 4:10 p.m. UTC

Hi all,

Board staging was introduced to host temporarily legacy board support
for platforms that are under active conversion to DT.  Currently it
hosts:
  1. USB Gadget support for the Kyoto Microcomputer Co. KZM-A9-Dual
     (KZM9D) development board,
  2. Display support for the Atmark Techno Armadillo-800-EVA development
     board.

During the last few years, the KZM9D development board didn't receive
much love.  Also, no one really cared about the EMMA Mobile USB Gadget
driver, which is also hosted under staging.

Hence this RFC patch series removes the KZM9D board staging support,
together with the EMMA Mobile USB Gadget driver, and the legacy EMMA
Mobile EV2 clkdev registration.

Once the SH-Mobile LCDC DRM driver has been converted to atomic
modesetting and DT, the remaining parts of board staging can be removed,
together with legacy clkdev registration in the MSTP driver.

Thanks for your comments!

To make it super-clear: we only lose USB gadget support by removing
this. And both, board code and driver, have been in staging for years,
hardly altered. The rest of the board will still be supported because
the other drivers gained DT support.

I am all for this!

Hi Geert,

Happy to see this work!
