[U-Boot] [PATCH 1/5] EXYNOS5: Change parent clock of FIMD to MPLL

[U-Boot] [PATCH 1/5] EXYNOS5: Change parent clock of FIMD to MPLL

[Ajay Kumar]

With VPLL as source clock to FIMD,
Exynos DP Initializaton was failing sometimes with unstable clock.
Changing FIMD source to resolves this issue.

[U-Boot] [PATCH 3/5] video: Fix compilation dependency of exynos_dp and exynos_mipi on exynos_fb

[Ajay Kumar]

When only DP is used, we need not enable CONFIG_EXYNOS_MIPI_DSIM.
Similarly, when only MIPI is used, we need not enable CONFIG_EXYNOS_DP.
But the current structuring of code forces us to enable both
CONFIG_EXYNOS_MIPI_DSIM and CONFIG_EXYNOS_DP.
This patch adds conditional compilation check to remove the dependency.

[U-Boot] [PATCH 4/5] EXYNOS5: Add support for FIMD and DP

[Ajay Kumar]

Add panel_info structure required by LCD driver
and DP panel platdata for SMDK5250.
Enable FIMD and DP support on SMDK5250.
DP Panel size: 2560x1600.
We use 16BPP resolution to get LCD console.

[U-Boot] [PATCH 5/5] video: Modify exynos_fimd driver to support LCD console.

[Ajay Kumar]

Currently, exynos FIMD driver is being used to support only TIZEN LOGOs.
In order to get LCD console, we need to enable half word swap feature
of FIMD and use 16 BPP.

It should be SMDK5250 specific codes, it can't located at common file.

At some point it would be nice to have defines for these, or even a
full clock api, with clock_set_rate(), clock_set_source(), etc.

Eventual FDT support should help to remove these ifdefs. But even in
the meantime, would it not be better to create a new
CONFIG_EXYNOS_FIMD_... option to select the behavior and then put the
option in the board config file?

You can use the cfg_gpio function at your board file.
