This patchset add support for display on Universal C210 board.
Max8998 is modified to power on display, new driver ld9040
and support for LCD display on universal C210 board is added.
Changes in v2:
- removed unnecessary function for fimd clock set;
- code cleanup
- removed patch for fix exynos4_fb structure
Piotr Wilczek (5):

This patchset add support for display on Universal C210 board.
Max8998 is modified to power on display, new driver ld9040
and support for LCD display on universal C210 board is added.
Changes in v2:
- removed unnecessary function for fimd clock set;
- code cleanup
- removed patch for fix exynos4_fb structure
Changes in v3:
- small changes in Patch 5/5 after some changes in another
patch ID=<1348487791-18435-2-git-send-email-p.wilczek@samsung.com>
on which this patch depends on.

This patchset add support for display on Universal C210 board.
Software SPI support is added to universal C210.
Max8998 is modified to power on display, new driver ld9040 is added
and support for LCD display on universal C210 board is added.
Changes in v2:
- removed unnecessary function for fimd clock set;
- code cleanup
- removed patch for fix exynos4_fb structure
Changes in v3:
- code cleanup
Changes in v4:
- removed comment and unused struct
- removed patch with unused display control define
Changes in v5:
- add patch to support soft SPI on Universal_C210
Piotr Wilczek (5):
exynos4: universal_C210: use software SPI
misc:max8998 Add LDO macros
drivers: video: Add ld9040 video driver

This patch add support for display on Universal C210 board.
Width of displyed logo must be not bigger than 480 pixel and
is limited by width of the screen.
Tizen logo size is 520x120 pixels and should be resized.

This patch, committed in Minkuy's tree as ff0fedd5, as well as
"exynos4: universal_C210: add display support", committed too, as
d984b9f8, conflict with PMIC/POWER reworks now in u-boot/master.
Piotr, can you see what neds reworking?
Minkyu, can you provide a pull request the same way as Stefano did for
the woodburn issue? See
<http://www.mail-archive.com/u-boot@lists.denx.de/msg101115.html>
Thanks in advance!
Amicalement,
