Linus series proposed to break out ili9882t as separate driver, but he didn't have time for that extensive rework of the driver. As discussed by Linus and Doug [1], keep macro using the "struct panel_init_cmd" until we get some resolution about the binary size issue. [1]: https://lore.kernel.org/all/20230703-fix-boe-tv101wum-nl6-v3-0-bd6e9432c755@xxxxxxxxxx In [v1 2/2], Doug suggested move the ili9882t_enter_sleep_mode function to ili9882t_unprepare. I tried this scheme and the test failed. I will continue to investigate the rootcause with ilitek, which may take a long time . So if possible, apply this patch first. If there are new solutions later, I will continue upstream.
