From 537e237608079a50a8f72c777c2fd5c9be82b227 Mon Sep 17 00:00:00 2001 From: Bilal Wasim Date: Mon, 12 Oct 2020 19:33:14 +0500 Subject: [PATCH] configs/chromebook_elm: bump to Linux v5.9 Update the chromebook elm configuration to use v5.9 instead of an intermediate release candidate. At the latter stages of the v5.9 release, a patch was added which broke the Chromebook Elm HDMI. Therefore add a revert patch to get rid of this problem. The fix (and the revert) are already on the mailing list (https://lkml.org/lkml/2020/10/10/32) and should become available with v5.10 Signed-off-by: Bilal Wasim Signed-off-by: Thomas Petazzoni --- ...tek-dsi-Fix-scrolling-of-panel-with-.patch | 41 +++++++++++++++++++ configs/chromebook_elm_defconfig | 2 +- 2 files changed, 42 insertions(+), 1 deletion(-) create mode 100644 board/chromebook/elm/patches/linux/0006-Revert-drm-mediatek-dsi-Fix-scrolling-of-panel-with-.patch diff --git a/board/chromebook/elm/patches/linux/0006-Revert-drm-mediatek-dsi-Fix-scrolling-of-panel-with-.patch b/board/chromebook/elm/patches/linux/0006-Revert-drm-mediatek-dsi-Fix-scrolling-of-panel-with-.patch new file mode 100644 index 0000000000..43bffe5261 --- /dev/null +++ b/board/chromebook/elm/patches/linux/0006-Revert-drm-mediatek-dsi-Fix-scrolling-of-panel-with-.patch @@ -0,0 +1,41 @@ +From 51109530891c981b681816152bd205724deabcca Mon Sep 17 00:00:00 2001 +From: Jitao Shi +Date: Sat, 10 Oct 2020 15:09:09 +0800 +Subject: [PATCH] Revert "drm/mediatek: dsi: Fix scrolling of panel with small + hfp or hbp" + +This reverts commit 35bf948f1edbf507f6e57e0879fa6ea36d2d2930. + +Signed-off-by: Jitao Shi +Reviewed-by: Bilal Wasim +Tested-by: Bilal Wasim +--- + drivers/gpu/drm/mediatek/mtk_dsi.c | 9 +++++---- + 1 file changed, 5 insertions(+), 4 deletions(-) + +diff --git a/drivers/gpu/drm/mediatek/mtk_dsi.c b/drivers/gpu/drm/mediatek/mtk_dsi.c +index 80b7a082e874..16fd99dcdacf 100644 +--- a/drivers/gpu/drm/mediatek/mtk_dsi.c ++++ b/drivers/gpu/drm/mediatek/mtk_dsi.c +@@ -466,13 +466,14 @@ static void mtk_dsi_config_vdo_timing(struct mtk_dsi *dsi) + horizontal_sync_active_byte = (vm->hsync_len * dsi_tmp_buf_bpp - 10); + + if (dsi->mode_flags & MIPI_DSI_MODE_VIDEO_SYNC_PULSE) +- horizontal_backporch_byte = vm->hback_porch * dsi_tmp_buf_bpp; ++ horizontal_backporch_byte = ++ (vm->hback_porch * dsi_tmp_buf_bpp - 10); + else +- horizontal_backporch_byte = (vm->hback_porch + vm->hsync_len) * +- dsi_tmp_buf_bpp; ++ horizontal_backporch_byte = ((vm->hback_porch + vm->hsync_len) * ++ dsi_tmp_buf_bpp - 10); + + data_phy_cycles = timing->lpx + timing->da_hs_prepare + +- timing->da_hs_zero + timing->da_hs_exit; ++ timing->da_hs_zero + timing->da_hs_exit + 3; + + if (dsi->mode_flags & MIPI_DSI_MODE_VIDEO_BURST) { + if ((vm->hfront_porch + vm->hback_porch) * dsi_tmp_buf_bpp > +-- +2.25.1 + diff --git a/configs/chromebook_elm_defconfig b/configs/chromebook_elm_defconfig index 0c8e0a42bf..05e82ffc31 100644 --- a/configs/chromebook_elm_defconfig +++ b/configs/chromebook_elm_defconfig @@ -12,7 +12,7 @@ BR2_TARGET_ROOTFS_EXT2_4=y # Kernel BR2_LINUX_KERNEL=y BR2_LINUX_KERNEL_CUSTOM_VERSION=y -BR2_LINUX_KERNEL_CUSTOM_VERSION_VALUE="5.9-rc5" +BR2_LINUX_KERNEL_CUSTOM_VERSION_VALUE="5.9" # Build Kernel with a Custom config.
