[Linux-fbdev-devel] [PATCH v2 0/3] v2: s3c-fb panning and vsync support

[Pawel O. <p.o...@sa...>]

Hello,

this is the second version of my previous patchset, corrected after your feedback (thank you).

[v2]:

In the panning patch:
* panning is done per-byte (the unit used in VIDW_BUF_START) and has been tested for different
bpps, including bpp < 8

* introduced the PRTCON register, which basically disables in-hardware updates from
shadow registers for VIDW_BUF_START/END (and a couple of others):
- shadow registers are updated on vsync (in hw)
- the update will not occur if PRTCON protection is enabled
This way we are safe when updating them at any time, even though they are separate.

In VSYNC patch:
* removed open() and release() functions as suggested (they were to disable interrupts at
release(), but this is already being taken care of in the isr)


The series contains:

[PATCH v2 1/3] [ARM] s3c-fb: Corrected defines for framesel1 register.
[PATCH v2 2/3] [ARM] s3c-fb: Added support for panning the display in both directions.
[PATCH v2 3/3] [ARM] s3c-fb: Added wait for VSYNC support.


Best regards
