But there are still three light registers setting differents bewteen
exynos and rk3288.
1. RK3288 have five special pll resigters which not indicata in exynos
dp controller.
2. The address of DP_PHY_PD(dp phy power manager register) are different
between rk3288 and exynos.
3. Rk3288 and exynos have different setting with AUX_HW_RETRY_CTL(dp debug
register).
This series have been well tested on Rockchip platform with eDP panel on
Jerry Chromebook and Display Port Monitor on RK3288 board. Also I have
tested on Samsung Snow and Peach Pit Chromebooks, and thanks to
Javier@Samsung help to retest the whole series on Samsung Exynos5800 Peach
Pi Chromebook, glad to say that things works rightlly.
Thanks,
- Yakir
Changes in v11:

- Correct the title of this rockchip dp phy document(Rob)
- Add the ack from Rob Herring
- Rename the "analogix,need-force-hpd" to common 'force-hpd' (Rob)
- Add the ack from Rob Herring
- Revert parts of Gustavo Padovan's changes in commit:
drm/exynos: do not start enabling DP at bind() phase
Add dp phy poweron function in bind time.
- Move the panel prepare from get_modes time to bind time, and move
the panel unprepare from bridge->disable to unbind time. (Heiko)
Changes in v10:
- Add the ack from Rob Herring
- Correct the ROCKCHIP_ANALOGIX_DP indentation in Kconfig to tabs here
(Heiko) - Add the ack from Rob Herring
- Fix the wrong macro value of GRF_EDP_REF_CLK_SEL_INTER_HIWORD_MASK
BIT(4) -> BIT(20)
- Remove the surplus "plat_data" check. (Heiko)
- switch (dp->plat_data && dp->plat_data->dev_type) {
+ switch (dp->plat_data->dev_type) {
Changes in v9:
- Document more details for 'ports' property.
- Removed the unused the variable "res" in probe function. (Heiko)
- Removed the unused head file.
Changes in v8:
- Correct the right document path of display-timing.txt (Heiko)
- Correct the misspell of 'from' to 'frm'. (Heiko)
- Modify the commit subject name. (Heiko)
- Fix the mixed spacers on macro definitions. (Heiko)
- Remove the unnecessary empty line after clk_prepare_enable. (Heiko)
- Remove the specific address in the example node name. (Heiko)
Changes in v7:
- Back to use the of_property_read_bool() interfacs to provoid backward
compatibility of "hsync-active-high" "vsync-active-high" "interlaced"
to avoid -EOVERFLOW error (Krzysztof)
- Simply the commit message. (Kishon)
- Symmetrical enable/disbale the phy clock and power. (Kishon)
- Simplify the commit message. (Kishon)
Changes in v6:
- Fix the Kconfig recursive dependency (Javier)
- Fix Peach Pit hpd property name error:
- hpd-gpio = <&gpx2 6 0>;
+ hpd-gpios = <&gpx2 6 0>;
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:
- 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
