Hi,looking at the code in 'drivers/staging/fbtft/fb_pcd8544.c', there seems to be some typos.
At the end of the file, we can find: FBTFT_REGISTER_DRIVER(DRVNAME, "philips,pdc8544", &display); ... MODULE_ALIAS("spi:pdc8544"); It is likely that the 2 pdc8544 should be pcd8544. (d and c switched)As I don't know the implication of such a change, I prefer to first report the potential issue, before proposing a patch for it.
Any feedback back appreciated. Best regards, Christophe JAILLET
