It is used on the ST-Ericsson HREF520 reference design. We support video mode by default, but it is possible to switch the panel into command mode by using the bool property "dsi-command-mode". Cc: Stephan Gerhold Signed-off-by: Linus Walleij --- ChangeLog v4->v5: - Bindings were iterated separately so a jump in versioning. - Add Stephan as reviewer. ChangeLog v3->v4: - No changes just resending with the new binding updates. ChangeLog v2->v3: - No changes just resending with the new binding updates. ChangeLog v1->v2: - Fix up the ID read function to split into reading header, version and ID, store the version in the struct. - Get rid of a surplus semicolon found by the build robot while rewriting the above code. - Use unsigned int in probe() loop. - Set vrefresh to 60Hz, as good as any, the measured vrefresh in continous command mode is ~117 Hz. - Use a different for() idiom while retrying to read ID 5 times. - Drop the sync pulse setting, we are not using this, this panel uses an event. - Use the generic "enforce-video-mode" for video mode enforcement. --- drivers/gpu/drm/panel/Kconfig | 7 + drivers/gpu/drm/panel/Makefile | 1 + drivers/gpu/drm/panel/panel-sony-acx424akp.c | 540 +++++++++++++++++++ include/video/mipi_display.h | 1 + 4 files changed, 549 insertions(+) create mode 100644 drivers/gpu/drm/panel/panel-sony-acx424akp.c diff --git a/drivers/gpu/drm/panel/Kconfig b/drivers/gpu/drm/panel/Kconfig index f152bc4eeb53..959df5bea7d2 100644 --- a/drivers/gpu/drm/panel/Kconfig +++ b/drivers/gpu/drm/panel/Kconfig @@ -316,6 +316,13 @@ config DRM_PANEL_SITRONIX_ST7789V Say Y here if you want to enable support for the Sitronix ST7789V controller for 240x320 LCD panels +config DRM_PANEL_SONY_ACX424AKP + tristate "Sony ACX424AKP DSI command mode panel" + depends on OF + depends on DRM_MIPI_DSI + depends on BACKLIGHT_CLASS_DEVICE + select VIDEOMODE_HELPERS + config DRM_PANEL_SONY_ACX565AKM tristate "Sony ACX565AKM panel" depends on GPIOLIB && OF && SPI diff --git a/drivers/gpu/drm/panel/Makefile b/drivers/gpu/drm/panel/Makefile index b6cd39fe0f20..0b51793e3b43 100644 --- a/drivers/gpu/drm/panel/Makefile +++ b/drivers/gpu/drm/panel/Makefile @@ -33,6 +33,7 @@ obj-$(CONFIG_DRM_PANEL_SHARP_LS037V7DW01) += panel-sharp-ls037v7dw01.o obj-$(CONFIG_DRM_PANEL_SHARP_LS043T1LE01) += panel-sharp-ls043t1le01.o obj-$(CONFIG_DRM_PANEL_SITRONIX_ST7701) += panel-sitronix-st7701.o obj-$(CONFIG_DRM_PANEL_SITRONIX_ST7789V) += panel-sitronix-st7789v.o +obj-$(CONFIG_DRM_PANEL_SONY_ACX424AKP) += panel-sony-acx424akp.o obj-$(CONFIG_DRM_PANEL_SONY_ACX565AKM) += panel-sony-acx565akm.o obj-$(CONFIG_DRM_PANEL_TPO_TD028TTEC1) += panel-tpo-td028ttec1.o obj-$(CONFIG_DRM_PANEL_TPO_TD043MTEA1) += panel-tpo-td043mtea1.o diff --git a/drivers/gpu/drm/panel/panel-sony-acx424akp.c b/drivers/gpu/drm/panel/panel-sony-acx424akp.c new file mode 100644 index 000000000000..2382b608b67b --- /dev/null +++ b/drivers/gpu/drm/panel/panel-sony-acx424akp.c @@ -0,0 +1,540 @@ +// SPDX-License-Identifier: GPL-2.0+ +/* + * MIPI-DSI Sony ACX424AKP panel driver.
