Signed-off-by: Yakir Yang --- Changes in v12: None Changes in v11: None Changes in v10: - Correct the ROCKCHIP_ANALOGIX_DP indentation in Kconfig to tabs here (Heiko) Changes in v9: None Changes in v8: None Changes in v7: None Changes in v6: None Changes in v5: - 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) Changes in v4: - Remove some deprecated DT properties in rockchip dp document. Changes in v3: - 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. Changes in v2: - 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. drivers/gpu/drm/rockchip/Kconfig | 9 + drivers/gpu/drm/rockchip/Makefile | 1 + drivers/gpu/drm/rockchip/analogix_dp-rockchip.c | 385 ++++++++++++++++++++++++ include/drm/bridge/analogix_dp.h | 1 + 4 files changed, 396 insertions(+) create mode 100644 drivers/gpu/drm/rockchip/analogix_dp-rockchip.c diff --git a/drivers/gpu/drm/rockchip/Kconfig b/drivers/gpu/drm/rockchip/Kconfig index 35215f6..686cb49 100644 --- a/drivers/gpu/drm/rockchip/Kconfig +++ b/drivers/gpu/drm/rockchip/Kconfig @@ -25,3 +25,12 @@ config ROCKCHIP_DW_HDMI for the Synopsys DesignWare HDMI driver.
