Hi all,
Friendly ping..... :)

Hi all,
The Samsung Exynos eDP controller and Rockchip RK3288 eDP controller
share the same IP, so a lot of parts can be re-used. I split the common
code into bridge directory, then rk3288 and exynos only need to keep
some platform code. Cause I can't find the exact IP name of exynos dp
controller, so I decide to name dp core driver with "analogix" which I
find in rk3288 eDP TRM :)
This time I create this version on linux-next branch (tag is next-20150918),
and also applied this version to Heiko github eDP branch to verify the function.
(https://github.com/mmind/linux-rockchip/tree/tmp/edp-with-veyron)
Glad to say my chromebook "cnm,n116bgeea2" eDP panel just lighted rightly on
Heiko branch. And after back port this series to chromeos-3.14 tree, my rk3288
SDK board still can light my 2K DisplayPort monitor. So this time would be okay
on mainline kernel and chromeos-3.14 tree. ;)
Due to no Exynos board in my side, so I haven't verified the eDP function on
samsung platform, I only ensure that there are no obvious compiled error. Any
help would be greatly appreciated. :)
Thanks,

Changes in v5:
- Correct the check condition of gpio_is_valid when driver try to get
the "hpd-gpios" DT propery. (Heiko)
- Move the platform attach callback in the front of core driver bridge
attch function. Cause once platform failed at attach, core driver should
still failed, so no need to init connector before platform attached
(Krzysztof)
- Keep code style no changes with the previous exynos_dp_code.c in this
patch, and update commit message about the new export symbol (Krzysztof)
- Gather the device type patch (v4 11/16) into this one. (Krzysztof)
- leave out the connector registration to analogix platform driver. (Thierry)
- Resequence this patch after analogix_dp driver have been split
from exynos_dp code, and rephrase reasonable commit message, and
remove some controversial style (Krzysztof)
- analogix_dp_write_byte_to_dpcd(
- dp, DP_TEST_RESPONSE,
+ analogix_dp_write_byte_to_dpcd(dp,
+ DP_TEST_RESPONSE,
DP_TEST_EDID_CHECKSUM_WRITE);
- Switch video timing type to "u32", so driver could use "of_property_read_u32"
to get the backword timing values. Krzysztof suggest me that driver could use
the "of_property_read_bool" to get backword timing values, but that interfacs
would modify the original drm_display_mode timing directly (whether those
properties exists or not).
- Correct the misspell in commit message. (Krzysztof)
- Remove the empty line at the end of document, and correct the endpoint
numbers in the example DT node, and remove the regulator iomux setting
in driver code while using the pinctl in devicetree instead. (Heiko)
- Add device type declared, cause the previous "platform device type
support (v4 11/16)" already merge into (v5 02/14).
- Implement connector registration code. (Thierry)
- Split binding doc's from driver changes. (Rob)
- Add eDP hotplug pinctrl property. (Heiko)
- Remove "reg" DT property, cause driver could poweron/poweroff phy via
the exist "grf" syscon already. And rename the example DT node from
"edp_phy: phy@ff770274" to "edp_phy: edp-phy" directly. (Heiko)
- Add deivce_node at the front of driver, update phy_ops type from "static
struct" to "static const struct". And correct the input paramters of
devm_phy_create() interfaces. (Heiko)
- Split binding doc's from driver changes. (Rob)
- Update the rockchip,grf explain in document, and correct the clock required
elemets in document. (Rob & Heiko)
- Fix compiled error (Heiko)
- Using the connector display info message to configure eDP driver input
video mode, but hard code CRTC video output mode to RGBaaa.
Changes in v4:
- Update "analogix,hpd-gpios" to "hpd-gpios" DT propery. (Rob)
- Rename "analogix_dp-exynos.c" file name to "exynos_dp.c" (Jingoo)
- Create a separate folder for analogix code in bridge/ (Archit)
- Update commit message more readable. (Jingoo)
- Adjust the order from 05 to 04
- Provide backword compatibility with samsung. (Krzysztof)
- Split all DTS changes, and provide backward compatibility. Mark old
properties as deprecated but still support them. (Krzysztof)
- Update "analogix,hpd-gpio" to "hpd-gpios" prop name. (Rob)
- Deprecated some properties which could parsed from Edid/Mode/DPCD. (Thierry)
"analogix,color-space" & "analogix,color-depth" &
"analogix,link-rate" & "analogix,lane-count" &
"analogix,ycbcr-coeff" & "analogix,dynamic-range" &
"vsync-active-high" & "hsync-active-high" & "interlaces"
- Separate all DTS changes to a separate patch. (Krzysztof)
- Remove some deprecated DT properties in rockchip dp document.
- Add commit message, and remove the redundant rockchip_dp_phy_init()
function, move those code to probe() method. And remove driver .owner
number. (Kishon)
- Seprate the link-rate and lane-count limit out with the device_type
flag. (Thierry)
- Take Jingoo suggest, add commit messages.
- Call drm_panel_prepare() in .get_modes function, ensure panel should
power on before driver try to read edid message.
Changes in v3:
- Move exynos's video_timing code to analogix_dp-exynos platform driver,
add get_modes method to struct analogix_dp_plat_data. (Thierry)
- Rename some "samsung*" dts propery to "analogix*". (Heiko)
- The link_rate and lane_count shouldn't config to the DT property value
directly, but we can take those as hardware limite. For example, RK3288
only support 4 physical lanes of 2.7/1.62 Gbps/lane, so DT property would
like "link-rate = 0x0a" "lane-count = 4". (Thierry)
- Dynamic parse video timing info from struct drm_display_mode and
struct drm_display_info. (Thierry)
- Add devicetree binding documents. (Heiko)
- Remove sync pol & colorimetry properies from the new analogix dp driver
devicetree binding. (Thierry)
- Update the exist exynos dtsi file with the latest DP DT properies.
- Leave "sclk_edp_24m" to rockchip dp phy driver which name to "24m",
and leave "sclk_edp" to analogix dp core driver which name to "dp",
and leave "pclk_edp" to rockchip dp platform driver which name to
"pclk". (Thierry & Heiko)
- Add devicetree binding document. (Heiko)
- Remove "rockchip,panel" DT property, take use of remote point to get panel
node. (Heiko)
- Add the new function point dp_platdata->get_modes() init.
- Suggest, add rockchip dp phy driver, collect the phy clocks and
power control. (Heiko)
- Add "analogix,need-force-hpd" to indicate whether driver need foce
hpd when hpd detect failed.
- move dp hpd detect to connector detect function.
- Add edid modes parse support
Changes in v2:
- Keep author name list no changed (Jingoo)
- Remove new copyright (Jingoo)
- Fix compiled failed due to analogix_dp_device misspell
- Improved commit message more readable, and avoid using some
uncommon style like bellow: (Joe Preches)
- retval = exynos_dp_read_bytes_from_i2c(...
...);
+ retval =
+ exynos_dp_read_bytes_from_i2c(......);
- Get panel node with remote-endpoint method, and create devicetree binding
for driver. (Heiko)
- Remove the clock enable/disbale with "sclk_edp" & "sclk_edp_24m",
leave those clock to rockchip dp phy driver.
- Fix compile failed dut to phy_pd_addr variable misspell error
