Merge tag 'fbdev-v5.3' of git://github.com/bzolnier/linux
Pull fbdev updates from Bartlomiej Zolnierkiewicz: - remove fbdev notifier usage for fbcon (as prep work to clean up the fbcon locking), add locking checks in vt/console code and make assorted cleanups in fbdev and backlight code (Daniel Vetter) - add COMPILE_TEST support to atmel_lcdfb, da8xx-fb, gbefb, imxfb, pvr2fb and pxa168fb drivers (me) - fix DMA API abuse in au1200fb and jz4740_fb drivers (Christoph Hellwig) - add check for new BGRT status field rotation bits in efifb driver (Hans de Goede) - mark expected switch fall-throughs in s3c-fb driver (Gustavo A. R. Silva) - remove fbdev mxsfb driver in favour of the drm version (Fabio Estevam) - remove broken rfbi code from omap2fb driver (me) - misc fixes (Arnd Bergmann, Shobhit Kukreti, Wei Yongjun, me) - misc cleanups (Gustavo A.

+ * switching from indices to proper pointers for fb_info everywhere.
+ *
+ * - fbcon doesn't bother with fb_lock/unlock at all. This is buggy, since it
+ * means concurrent access to the same fbdev from both fbcon and userspace
+ * will blow up. To fix this all fbcon calls from fbmem.c need to be moved out
+ * of fb_lock/unlock protected sections, since otherwise we'll recurse and
+ * deadlock eventually. Aside: Due to these deadlock issues the fbdev code in
+ * fbmem.c cannot use locking asserts, and there's lots of callers which get

- * @brief LCDIF driver for i.MX23 and i.MX28
- *
- * The LCDIF support four modes of operation
- * - MPU interface (to drive smart displays) -> not supported yet
- * - VSYNC interface (like MPU interface plus Vsync) -> not supported yet
- * - Dotclock interface (to drive LC displays with RGB data and sync signals)
- * - DVI (to drive ITU-R BT656) -> not supported yet
- *
- * This driver depends on a correct setup of the pins used for this purpose
- * (platform specific).
- *
- * For the developer: Don't forget to set the data bus width to the display
- * in the imx_fb_videomode structure. You will else end up with ugly colours.
- * If you fight against jitter you can vary the clock delay. This is a feature
- * of the i.MX28 and you can vary it between 2 ns ... 8 ns in 2 ns steps. Give
- * the required value in the imx_fb_videomode structure.
