The bare ULCB SK has only an HDMI encoder +in use on port 1. When the system is booted with an SK +dtb, port 1's HDMI encoder is assigned as HDMI-A-1 because +it is the first (and only) encoder present. When booting +a KF dtb, port 0's HDMI encoder preceeds port1 in the dtb due +to incremental ordering of the endpoint port nodes. This causes +the KF HDMI to be assigned HDMI-A-1 and the SK HDMI to be assigned +as HDMI-A-2. In order to preserve the SK's HDMI output naming as +connector HDMI-A-1, reorder the endpoint port nodes so that port1 +is first. + +Change-Id: Ibbb1975c2383a526a54c257fb7d68d32a042d468 +Signed-off-by: Matt Porter <mporter@konsulko.com> +--- + arch/arm64/boot/dts/renesas/r8a7796.dtsi | 10 +++++----- + 1 file changed, 5 insertions(+), 5 deletions(-) + +diff --git a/arch/arm64/boot/dts/renesas/r8a7796.dtsi b/arch/arm64/boot/dts/renesas/r8a7796.dtsi +index bf37b8aa0e2f..e3a5c25bc3da 100644 +--- a/arch/arm64/boot/dts/renesas/r8a7796.dtsi ++++ b/arch/arm64/boot/dts/renesas/r8a7796.dtsi +@@ -2391,11 +2391,6 @@ + #address-cells = <1>; + #size-cells = <0>; + +- port@0 { +- reg = <0>; +- du_out_rgb: endpoint { +- }; +- }; + port@1 { + reg = <1>; + du_out_hdmi0: endpoint { +@@ -2406,6 +2401,11 @@ + du_out_lvds0: endpoint { + }; + }; ++ port@0 { ++ reg = <0>; ++ du_out_rgb: endpoint { ++ }; ++ }; + }; + }; + +-- +2.11.0 + diff --git a/meta-rcar-gen3-adas/recipes-kernel/linux/linux-renesas/ulcb.cfg b/meta-rcar-gen3-adas/recipes-kernel/linux/linux-renesas/ulcb.cfg index 002480e..0fd7e07 100644 --- a/meta-rcar-gen3-adas/recipes-kernel/linux/linux-renesas/ulcb.cfg +++ b/meta-rcar-gen3-adas/recipes-kernel/linux/linux-renesas/ulcb.cfg @@ -71,16 +71,10 @@ CONFIG_DRM_I2C_ADV7511=y CONFIG_TOUCHSCREEN_EDT_FT5X06=y CONFIG_SERIAL_SH_SCI_DMA=y CONFIG_STAGING=y -CONFIG_MOST=y -CONFIG_MOSTCORE=y -CONFIG_AIM_CDEV=y -CONFIG_AIM_NETWORK=y -CONFIG_AIM_SOUND=y -CONFIG_AIM_V4L2=y -CONFIG_HDM_DIM2=y CONFIG_UIO=y CONFIG_SENSORS_EMC2103=y CONFIG_PMBUS=y CONFIG_RTC_DRV_DS1307=y CONFIG_RTC_DRV_DS1307_HWMON=y CONFIG_SENSORS_LM63=y +CONFIG_MMC_SDHI_SEQ_WORKAROUND=y diff --git a/meta-rcar-gen3-adas/recipes-kernel/linux/linux-renesas_4.9.bbappend b/meta-rcar-gen3-adas/recipes-kernel/linux/linux-renesas_4.9.bbappend index 110d8bb..c4cad0f 100644 --- a/meta-rcar-gen3-adas/recipes-kernel/linux/linux-renesas_4.9.bbappend +++ b/meta-rcar-gen3-adas/recipes-kernel/linux/linux-renesas_4.9.bbappend @@ -3,6 +3,17 @@ FILESEXTRAPATHS_prepend := "${THISDIR}/${PN}:" COMPATIBLE_MACHINE_eagle = "eagle" COMPATIBLE_MACHINE_v3msk = "v3msk" +BRANCH = "v4.9/rcar-3.5.9" +SRCREV = "2c20c9881d53f1b5c7a3ebf55bb83ec15902d0d0" + +KERNEL_MODULE_PROBECONF += "btwilink" +module_conf_btwilink = "blacklist btwilink" + +SRC_URI_remove = " \ + file://0001-dmaengine-rcar-dmac-ensure-CHCR-DE-bit-is-actually-0.patch \ + file://0002-dmaengine-rcar-dmac-use-TCRB-instead-of-TCR-for-resi.patch \ +" + SRC_URI_append = " \ ${@bb.utils.contains('MACHINE_FEATURES', 'h3ulcb-had', ' file://hyperflash.cfg', '', d)} \ ${@base_conditional("SDHI_SEQ", "1", " file://sdhi_seq.cfg", "", d)} \ @@ -41,7 +52,6 @@ SRC_URI_append = " \ file://0034-media-soc_camera-Fix-VIDIOC_S_SELECTION-ioctl-miscal.patch \ file://0035-regulator-fixed-probe-after-i2c.patch \ file://0040-arm64-dts-renesas-add-ADAS-boards.patch \ - file://0041-arm64-dts-renesas-ulcb-enlarge-cma-region.patch \ file://0042-arm64-dts-renesas-r8a7795-es1-h3ulcb-disable-eMMC.patch \ file://0043-arm64-dts-renesas-ulcb-use-versaclock-for-du-rgb-and-lvds.patch \ file://0044-pinctrl-r8a779x-add-mlb-pinmux.patch \ @@ -71,6 +81,8 @@ SRC_URI_append = " \ file://0078-MOST-aim-fix-null-pointer-crash.patch \ file://0079-Revert-dmaengine-rcar-dmac-use-TCRB-instead-of-TCR-f.patch \ file://0082-gpio-pca953x-fix-interrupt-trigger.patch \ + file://0001-arm64-dts-renesas-preserve-drm-HDMI-connector-naming.patch \ + file://0001-arm64-dts-renesas-disable-r8a7796-hscif0-dma.patch \ " SRC_URI_append_r8a7797 = " \ |
