changes since v1:
Since v1 was not tested when I posted it, now that I have the s6e8aa0 panel, I
tested the same on Exynos5 SoC. Needed to make below mentioned changes to make
it work.
In exynos mipi driver:
1> added "enable_hs" as part of "dsi_video_source_ops", as this function
needs to be called from the s6e8aa0 panel probe after LCD "power_on".
2> moved the call exynos_mipi_dsi_set_hs_enable()
out of the exynos_mipi_update_cfg() function as it needs to be called
only
after the LCD "power_on". hence in s6e8aa0 probe added call "enable_hs"
after "power_on". otherwise DSI COMMAND TIME OUT error occurs, after
sending WRITE COMMAND.
Prior to CDF changes, things used to work fine, as the panel
used to register with MIPI DSIM driver and in the MIPI DSI probe used
to
call LCD "power_on" first and then "exynos_mipi_dsi_set_hs_enable".
Since the CDF support is introduced, the both panel and mipi dsi probe
happens independently and DSI COMMAND TIME OUT error used to occurs,
after
sending WRITE COMMAND. by making above mentioned changes it started
working.
In s6e8ax0 driver:
1> added call "enable_hs" in probe after "power_on", to over come above
mentioned error.
2> addd init_lcd(), the missing sequence to initialise the lcd.
This patch series contains 3 patches with the following changes

[PATCH 1/3] video: display: Adding frame related ops to MIPI DSI video source
struct
Adds the frame related ops to the MIPI DSI video source struct
[PATCH 2/3] video: exynos: mipi dsi: Making Exynos MIPI Compliant with CDF
Makes the Exynos MIPI DSI driver compliant with CDF.
[PATCH 3/3] video: exynos: Making s6e8ax0 panel driver compliant with CDF
Makes the Exynos s6e8ax0 panel driver compliant with CDF.
Have made necessary changes in s6e8ax0 panel driver, made an effort to
remove dependency on backlight and lcd framework, but its NOT fully
done.
s6e8ax0_get_brightness() and s6e8ax0_set_brightness() functionalities
have NOT been modified. as backlight support in CDF are _NOT_
implemented yet.
Thought of adding these "get and set" as part of
display_entity_control_ops(), but didn't modify as of now.
Any thoughts on the same will be helpful.
removed the lcd_ops "set_power and get_power" and added as part of
panel_set_state.
Testing:
Tested on Exynos5 SoC with s6e8aa0 panel connected, by applying some of
the dependent patches
Could see the linux logo and ran "modetest" application and saw the
test pattern on display panel.
