Merge tag 'fbdev-v4.20' of https://github.com/bzolnier/linux

Pull fbdev updates from Bartlomiej Zolnierkiewicz:
"No major changes to the subsystem itself, mainly fb drivers fixes &
cleanups (atyfb & udlfb updates stand out from the rest) + removal of
no longer needed old clps711xfb driver.

Details:

- update atyfb driver - improvements for ATI Mach64 chips: detect the
dot clock divider correctly on Sparc, fix display corruptions (due
to endianness issues and improper reading of accelerator
registers), optimize scrolling performance and also fix debugging
printks (Mikulas Patocka)

- rewrite USB unplug handling in udlfb driver using framebuffer
subsystem reference counting (Mikulas Patocka)

- fix support for native-mode display-timings in atmel_lcdfb driver
(Sam Ravnborg)

- fix information leak & add missing access_ok() checks in sbuslib
(Dan Carpenter)

- allow using GPIO expanders that can sleep in ssd1307fb driver
(Michal Vokáč)

- convert omapfb driver to use GPIO descriptors instead of GPIO
numbers for Amstrad Delta board (Janusz Krzysztofik)

- fix broken Kconfig menu dependencies (Randy Dunlap)

- convert fbdev subsystem to use %pOFn instead of device_node.name
(Rob Herring)

- remove the dead old CLPS711x LCD support driver (the new CLPS711x
LCD support driver is still available)

- misc fixes (Jia-Ju Bai, Gustavo A. R. Silva)

- misc cleanups (Mehdi Bounya, Nathan Chancellor, YueHaibing)"

mach64: fix image corruption due to reading accelerator registers

Reading the registers without waiting for engine idle returns
unpredictable values. These unpredictable values result in display
corruption - if atyfb_imageblit reads the content of DP_PIX_WIDTH with the
bit DP_HOST_TRIPLE_EN set (from previous invocation), the driver would
never ever clear the bit, resulting in display corruption.

We don't want to wait for idle because it would degrade performance, so
this patch modifies the driver so that it never reads accelerator
registers.

HOST_CNTL doesn't have to be read, we can just write it with
HOST_BYTE_ALIGN because no other part of the driver cares if
HOST_BYTE_ALIGN is set.

DP_PIX_WIDTH is written in the functions atyfb_copyarea and atyfb_fillrect
with the default value and in atyfb_imageblit with the value set according
to the source image data.

mach64: fix display corruption on big endian machines

The code for manual bit triple is not endian-clean. It builds the variable
"hostdword" using byte accesses, therefore we must read the variable with
"le32_to_cpu".

The patch also enables (hardware or software) bit triple only if the image
is monochrome (image->depth). If we want to blit full-color image, we
shouldn't use the triple code.
