support for ssd_1305 #594

I couldn't find the driver for ssd1305. Has its support been dropped ?

notro commented 1 year ago

It's in mainline Linux: https://elixir.bootlin.com/linux/latest/source/drivers/staging/fbtft/fb_ssd1305.c

got you. thanks.. Won't it be useful to have the following initialization for CS and DS line in the init function:

+++ b/drivers/staging/fbtft/fb_ssd1305.c
@@ -43,6 +43,8 @@ static int init_display(struct fbtft_par *par)
                mutex_unlock(&par->gamma.lock);
        }

+       par->gpio.reset = 1;
+       par->gpio.dc = 0;
        /* Set Display OFF */
        write_reg(par, 0xAE);

'reset' and 'dc' are pointers to struct gpio_desc so this won't work (struct fbtft_par).

Why do you want to do this?
