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 ;)
Beyond that, there are 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).
I have verified this series on two kinds of rockchip platform board, one
is rk3288 sdk board which connect with a 2K display port monitor, the other
is google jerry chromebook which connect with a eDP screen "cnm,n116bgeea2",
both of them works rightlly.
I haven't verified the dp function on samsung platform, cause I haven't got
exynos boards. I can only ensure that there are no build error on samsung
platform, wish some samsung guys help to test. ;)
Thanks,
- Yakir
Changes in v3:
- Take Thierry Reding suggest, move exynos's video_timing code
to analogix_dp-exynos platform driver, add get_modes method
to struct analogix_dp_plat_data.
- Take Heiko suggest, rename some "samsung*" dts propery to "analogix*".
- Take Thierry Reding suggest, dynamic parse video timing info from
struct drm_display_mode and struct drm_display_info.
- Take Thierry Reding suggest, 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".
- Take Heiko suggest, add devicetree binding documents.
- Take Thierry Reding suggest, remove sync pol & colorimetry properies
from the new analogix dp driver devicetree binding.
- Update the exist exynos dtsi file with the latest DP DT properies.
- Take Thierry Reding and Heiko suggest, 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".
- Take Heiko suggest, add devicetree binding document.
- Take Heiko suggest, remove "rockchip,panel" DT property, take use of remote
point to get panel node.
- Add the new function point analogix_dp_platdata.get_modes init.
- Take Heiko suggest, add rockchip dp phy driver,
collect the phy clocks and power control.
- 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:
- Take Joe Preches advise, improved commit message more readable, and
avoid using some uncommon style like bellow:
- retval = exynos_dp_read_bytes_from_i2c(...
...)
+ retval =
+ exynos_dp_read_bytes_from_i2c(......);
- Take Jingoo Han suggest, just remove my name from author list.
- Take Jingoo Han suggest, remove new copyright
- Fix compiled failed dut to analogix_dp_device misspell
- Take Heiko suggest, get panel node with remote-endpoint method,
and create devicetree binding for driver.
- Remove the clock enable/disbale with "sclk_edp" & "sclk_edp_24m",
leave those clock to rockchip dp phy driver.
- Add GNU license v2 declared and samsung copyright
- Fix compile failed dut to phy_pd_addr variable misspell error
