[U-Boot] [PATCH V4 0/4] Add support for FIMD and DP on SMDK5250
Changes since V3: -- Make the dummy definition for "exynos_mipi_dsi_init" static and inline. -- Remove #ifdef, instead use logo_on field to add LCD console support.
[PATCH V2 RESEND 1/4] EXYNOS5: Change parent clock of FIMD to MPLL [PATCH V2 2/4] EXYNOS: Add dummy definition to fix compilation dependency on CONFIG_EXYNOS_MIPI_DSIM [PATCH V4 3/4] video: Modify exynos_fimd driver to support LCD console [PATCH V4 4/4] EXYNOS5: Add support for FIMD and DP

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

When only DP is used, we need not enable CONFIG_EXYNOS_MIPI_DSIM. But if we do not select CONFIG_EXYNOS_MIPI_DSIM, exynos_fb.c throws error saying exynos_mipi_dsi_init() not defined. So, we add dummy definition for exynos_mipi_dsi_init when CONFIG_EXYNOS_MIPI_DSIM is not defined.

LCD console and proprietary Logo cannot be used simultaneously. We use logo_on field inside vidinfo_t structure to decide whether user wants Logo or Console.

I am using CONFIG_CMD_BMP to differentiate between LCD Logo and LCD console. I select CONFIG_CMD_BMP only when I need Logo, and I will not select CONFIG_CMD_BMP when I need console. Lets consider that we want console. So we don't define CONFIG_CMD_BMP now. And, exynos_fb.c has linking time dependency on "bmp_display", which is not defined! In such a case, I am left with 2 options: 1) Place an #ifdef CONFIG_CMD_BMP inside exynos_fb, where it makes a call to "bmp_display". 2) Redefine "bmp_display" to do nothing inside a header file(That's how it is done in this patch!) Kindly let me know if you have a better way to do this.
Thanks, Minkyu Kang. ___________

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

No it's smdk5250 specific. Other board has different GPIOs.

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

Cant this GPIO changes go to pinmux file?
No. It is a board specific feature. So, can't be located in pinmux file.
Thanks. Minkyu Kang.
Hi Minkyu,
Thank you for clarification.
