From cddd4591404fb4c53dc0b3c0b15b942cdbed4356 Mon Sep 17 00:00:00 2001 From: Yangbo Lu Date: Fri, 10 Apr 2020 10:47:05 +0800 Subject: layerscape: add patches-5.4 Add patches for linux-5.4. The patches are from NXP LSDK-20.04 release which was tagged LSDK-20.04-V5.4. https://source.codeaurora.org/external/qoriq/qoriq-components/linux/ For boards LS1021A-IOT, and Traverse-LS1043 which are not involved in LSDK, port the dts patches from 4.14. The patches are sorted into the following categories: 301-arch-xxxx 302-dts-xxxx 303-core-xxxx 701-net-xxxx 801-audio-xxxx 802-can-xxxx 803-clock-xxxx 804-crypto-xxxx 805-display-xxxx 806-dma-xxxx 807-gpio-xxxx 808-i2c-xxxx 809-jailhouse-xxxx 810-keys-xxxx 811-kvm-xxxx 812-pcie-xxxx 813-pm-xxxx 814-qe-xxxx 815-sata-xxxx 816-sdhc-xxxx 817-spi-xxxx 818-thermal-xxxx 819-uart-xxxx 820-usb-xxxx 821-vfio-xxxx Signed-off-by: Yangbo Lu --- ...0005-gpu-drm-Add-imx8qm-mq-DP-HDMI-driver.patch | 2307 ++++++++++++++++++++ 1 file changed, 2307 insertions(+) create mode 100644 target/linux/layerscape/patches-5.4/805-display-0005-gpu-drm-Add-imx8qm-mq-DP-HDMI-driver.patch (limited to 'target/linux/layerscape/patches-5.4/805-display-0005-gpu-drm-Add-imx8qm-mq-DP-HDMI-driver.patch') diff --git a/target/linux/layerscape/patches-5.4/805-display-0005-gpu-drm-Add-imx8qm-mq-DP-HDMI-driver.patch b/target/linux/layerscape/patches-5.4/805-display-0005-gpu-drm-Add-imx8qm-mq-DP-HDMI-driver.patch new file mode 100644 index 0000000000..f4e428bee0 --- /dev/null +++ b/target/linux/layerscape/patches-5.4/805-display-0005-gpu-drm-Add-imx8qm-mq-DP-HDMI-driver.patch @@ -0,0 +1,2307 @@ +From 1433ad0f114ec80b524768af8ec96e09a5bba9b2 Mon Sep 17 00:00:00 2001 +From: Sandor Yu +Date: Fri, 23 Aug 2019 14:05:16 +0800 +Subject: [PATCH] gpu: drm: Add imx8qm/mq DP/HDMI driver + +Add imx8qm/mq DP/hdmi driver + +Signed-off-by: Sandor Yu +--- + drivers/gpu/drm/imx/Kconfig | 9 + + drivers/gpu/drm/imx/Makefile | 1 + + drivers/gpu/drm/imx/cdn-mhdp-dp-phy.c | 533 ++++++++++++++++++++++++ + drivers/gpu/drm/imx/cdn-mhdp-hdmi-phy.c | 684 ++++++++++++++++++++++++++++++ + drivers/gpu/drm/imx/cdn-mhdp-imx8mq.c | 163 ++++++++ + drivers/gpu/drm/imx/cdn-mhdp-imx8qm.c | 714 ++++++++++++++++++++++++++++++++ + drivers/gpu/drm/imx/cdn-mhdp-phy.h | 153 +++++++ + 7 files changed, 2257 insertions(+) + create mode 100644 drivers/gpu/drm/imx/cdn-mhdp-dp-phy.c + create mode 100644 drivers/gpu/drm/imx/cdn-mhdp-hdmi-phy.c + create mode 100644 drivers/gpu/drm/imx/cdn-mhdp-imx8mq.c + create mode 100644 drivers/gpu/drm/imx/cdn-mhdp-imx8qm.c + create mode 100644 drivers/gpu/drm/imx/cdn-mhdp-phy.h + +--- a/drivers/gpu/drm/imx/Kconfig ++++ b/drivers/gpu/drm/imx/Kconfig +@@ -39,3 +39,12 @@ config DRM_IMX_HDMI + depends on DRM_IMX + help + Choose this if you want to use HDMI on i.MX6. ++ ++config DRM_IMX_CDNS_MHDP ++ tristate "NXP i.MX MX8 DRM HDMI/DP" ++ select DRM_CDNS_MHDP ++ select DRM_CDNS_DP ++ select DRM_CDNS_HDMI ++ depends on DRM_IMX ++ help ++ Choose this if you want to use HDMI on i.MX8. +--- a/drivers/gpu/drm/imx/Makefile ++++ b/drivers/gpu/drm/imx/Makefile +@@ -9,3 +9,4 @@ obj-$(CONFIG_DRM_IMX_TVE) += imx-tve.o + obj-$(CONFIG_DRM_IMX_LDB) += imx-ldb.o + + obj-$(CONFIG_DRM_IMX_HDMI) += dw_hdmi-imx.o ++obj-$(CONFIG_DRM_IMX_CDNS_MHDP) += cdn-mhdp-imx8qm.o cdn-mhdp-imx8mq.o cdn-mhdp-dp-phy.o cdn-mhdp-hdmi-phy.o +--- /dev/null ++++ b/drivers/gpu/drm/imx/cdn-mhdp-dp-phy.c +@@ -0,0 +1,533 @@ ++/* ++ * Cadence Display Port Interface (DP) PHY driver ++ * ++ * Copyright (C) 2019 NXP Semiconductor, Inc. ++ * ++ * This program is free software;
