video: sunxi: de2: switch to public uclass functions

2021-04-24T11:45:03+00:00

Currently DE2 driver uses functions which are defined in internal
headers. They are not meant to be used outside of uclass framework.
Switch DE2 driver to public ones. This has additional benefit that
device_probe doesn't need to be called manually.

video: sunxi: dw-hdmi: read source_id later

2021-04-24T11:44:59+00:00

There is no real need to read source_id at probe time. It also doesn't
make sense to store it in driver private data since it's already stored
in class platform data. While this looks like cleanup (and it is), it's
also important for DE2 driver rework because this info will be filled
later (after probe is already executed).

No Allwinner board with DW-HDMI controller use separate I2C bus for
EDID read. Remove that check.

video: sunxi: Use DW-HDMI hpd function

2021-04-24T11:44:49+00:00

It turns out that there are two ways how hot plug detection can be done.
One is standard way for DW HDMI controller - checking bit 2 in 0x3004
register. Another way is applicable only to Allwinner custom PHY - by
checking bit 19 in register 0x10038. Both methods are equally good as
far as we know.

Use standard method in order to reduce amount of custom code.

Currently driver accepts all resolution which won't work on 4k screens.
Add validation callback which limits acceptable resolutions to 297 MHz.

sunxi: video: select dw-hdmi in Kconfig, not Makefile

2021-04-16T00:12:59+00:00

Currently sunxi Makefile manually specifies full path to dw-hdmi common
code. However, that is not needed because it can be selected in Kconfig
instead.

Select proper symbol in Kconfig and drop path from Makefile.

video: Fix line padding calculation for 16 and 24 BPP bitmaps

2021-04-10T15:09:59+00:00

Each row in the pixel array in the bitmap file is padded
if necessary so the row size is always a multiple of 4 bytes.
In current code the complement of row size to a multiple of
4 bytes is further unnecessarily multiplied by the pixel size.
This results in incorrect displaying of bitmaps having row size
that is not a multiple of 4 bytes. Fix this by removing
the unnecessary multiplication.

Tested with 24BPP bitmap and XRGB32 display.
