From 2a994cbed6b244e7d37886481cb03f2d4043c1ec Mon Sep 17 00:00:00 2001 From: Nickey Yang Date: Tue, 30 Oct 2018 10:15:28 +0100 Subject: [PATCH] drm/panel: Add Kingdisplay KD097D04 panel driver Support Kingdisplay KD097D04 9.7" 1536x2048 TFT LCD panel, it is a MIPI dual-DSI panel. v4-resend: - Thierry noted missing dt-bindings for v4 but forgot that he already had applied them one kernel release back in https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/commit/?id=ebc950fdff6d5f9250cd5a5a348af97f7d8508df v4: - address Philipp's comments - real range for usleep_range and - poweroff ordering in kingdisplay_panel_prepare - return value beautification in panel_probe - update author naming for full name v3: - address Thierry's comments - error handling for init dsi writes in init - unconditionally remove the panel - don't use drm_panel_detach - a bit of variable signednes wiggling - I did talk to ChromeOS people and the delays really should be as short as possible, so dropped the 100ms from the delay comments v2: - update timing + cmds from chromeos kernel - new backlight API including switch to devm_of_find_backlight - fix most of Sean Paul's comments enable/prepare tracking seems something all panels do - document origins of the init sequence - lanes per dsi interface to 4 (two interfaces). Matches how tegra and pending rockchip dual-dsi handle (dual-)dsi lanes - spdx header instead of license boilerplate Signed-off-by: Nickey Yang Signed-off-by: Heiko Stuebner Reviewed-by: Sean Paul Signed-off-by: Thierry Reding Link: https://patchwork.freedesktop.org/patch/msgid/20181030091528.28211-1-heiko@sntech.de --- drivers/gpu/drm/panel/Kconfig | 11 + drivers/gpu/drm/panel/Makefile | 1 + .../drm/panel/panel-kingdisplay-kd097d04.c | 473 ++++++++++++++++++ 3 files changed, 485 insertions(+) create mode 100644 drivers/gpu/drm/panel/panel-kingdisplay-kd097d04.c diff --git a/drivers/gpu/drm/panel/Kconfig b/drivers/gpu/drm/panel/Kconfig index 1aeb4a901d06..3e070153ef21 100644 --- a/drivers/gpu/drm/panel/Kconfig +++ b/drivers/gpu/drm/panel/Kconfig @@ -77,6 +77,17 @@ config DRM_PANEL_JDI_LT070ME05000 The panel has a 1200(RGB)×1920 (WUXGA) resolution and uses 24 bit per pixel. +config DRM_PANEL_KINGDISPLAY_KD097D04 + tristate "Kingdisplay kd097d04 panel" + depends on OF + depends on DRM_MIPI_DSI + depends on BACKLIGHT_CLASS_DEVICE + help + Say Y here if you want to enable support for Kingdisplay kd097d04 + TFT-LCD modules.
