71f56b27 - drm/ingenic: Add dw-hdmi driver specialization for jz4780

Thu, 07 Apr 2022 11:16:11 +0000

drm/ingenic: Add dw-hdmi driver specialization for jz4780A specialisation of the generic Synopsys HDMI driver is employed forJZ4780 HDMI support. This requires a new driver, plus device tree andconfiguration modifications.Here we add Kconfig DRM_INGENIC_DW_HDMI, Makefile and driver code.Note that there is no hpd-gpio installed on the CI20 board HDMIconnector. Hence there is no hpd detection by the connector driverand we have to enable polling in the dw-hdmi core driver.For that we need to set .poll_enabled but that struct componentcan only be accessed by core code. Hence we use the publicsetter function drm_kms_helper_hotplug_event() introduced before.Also note that we disable Color Space Conversion since it is notworking on jz4780.Signed-off-by: Paul Boddie Signed-off-by: Ezequiel Garcia Signed-off-by: H.

fc1acf31 - drm/ingenic: Add support for the IPU

Thu, 16 Jul 2020 16:38:44 +0000

drm/ingenic: Add support for the IPUAdd support for the Image Processing Unit (IPU) found in all IngenicSoCs.The IPU can upscale and downscale a source frame of arbitrary sizeranging from 4x4 to 4096x4096 on newer SoCs, with bicubic filteringon newer SoCs, bilinear filtering on older SoCs. Nearest-neighbour canalso be obtained with proper coefficients.Starting from the JZ4725B, the IPU supports a mode where its output issent directly to the LCDC, without having to be written to RAM first.This makes it possible to use the IPU as a DRM plane on the compatibleSoCs, and have it convert and scale anything the userspace asks for towhat's available for the display.Regarding pixel formats, older SoCs support packed YUV 4:2:2 and variousplanar YUV formats. Newer SoCs introduced support for RGB.Since the IPU is a separate hardware block, to make it work properly theIngenic DRM driver will now register itself as a component master incase the IPU driver has been enabled in the config.When enabled in the config, the CRTC will see the IPU as a second primaryplane. It cannot be enabled at the same time as the regular primaryplane. It has the same priority, which means that it will also displaybelow the overlay plane.v2: - ingenic-ipu is no longer its own module. It will be built into the ingenic-drm module. - If enabled in the config, both the core driver and the IPU driver will register as components; otherwise the core driver will bypass that and call the ingenic_drm_bind() function directly. - Since both files now build into the same module, the symbols previously exported as GPL are not exported anymore, since they are only used internally. - Fix SPDX license header in ingenic-ipu.h - Avoid using 'for(;;);' loops without trailing statement(s)v3: - Pass priv structure to IRQ handler; that way we don't hardcode the expectation that the IPU plane is at index #0. - Rework osd_changed() to account for src_* changes - Add multiplanar YUV 4:4:4 support - Commit fb addresses to HW at vblank, since addr registers are not shadow registers - Probe IPU component later so that IPU plane is last - Fix driver not working on IPU-less hardware - Use IPU driver's name as the IRQ name to avoid having two 'ingenic-drm' in /proc/interrupts - Fix IPU only working for still images on JZ4725B - Add a bit more code commentsSigned-off-by: Paul Cercueil Reviewed-by: Sam Ravnborg Link: https://patchwork.freedesktop.org/patch/msgid/20200716163846.174790-10-paul@crapouillou.net List of files: /linux-6.15/drivers/gpu/drm/ingenic/Makefile

54fe8942 - drm/ingenic: Rename ingenic-drm.c to ingenic-drm-drv.c

drm/ingenic: Rename ingenic-drm.c to ingenic-drm-drv.cFull rename without any modification, except to the Makefile.Renaming ingenic-drm.c to ingenic-drm-drv.c allow to decouple the modulename from the source file name in the Makefile.

90b86fcc - DRM: Add KMS driver for the Ingenic JZ47xx SoCs

Mon, 03 Jun 2019 15:23:31 +0000

DRM: Add KMS driver for the Ingenic JZ47xx SoCsAdd a KMS driver for the Ingenic JZ47xx family of SoCs.This driver is meant to replace the aging jz4740-fb driver.This driver does not make use of the simple pipe helper, for the reasonthat it will soon be updated to support more advanced features likemultiple planes, IPU integration for colorspace conversion and up/downscaling, support for DSI displays, and TV-out and HDMI outputs.Notes: v2: - Remove custom handling of panel. The panel is now discovered using the standard API. - Lots of small tweaks suggested by upstream v3: - Use devm_drm_dev_init() - Update compatible strings to -lcd instead of -drm - Add destroy() callbacks to plane and crtc - The ingenic,lcd-mode is now read from the bridge's DT node v4: Remove ingenic,lcd-mode property completely. The various modes are now deduced from the connector type, the pixel format or the bus flags. v5: - Fix framebuffer size incorrectly calculated for 24bpp framebuffers - Use 32bpp framebuffer instead of 16bpp, as it'll work with both 16-bit and 24-bit panel - Get rid of drm_format_plane_cpp() which has been dropped upstream - Avoid using drm_format_info->depth, which is deprecated.Signed-off-by: Paul Cercueil Tested-by: Artur Rojek Reviewed-by: Sam Ravnborg Signed-off-by: Sam Ravnborg Link: https://patchwork.freedesktop.org/patch/msgid/20190603152331.23160-2-paul@crapouillou.net List of files: /linux-6.15/drivers/gpu/drm/ingenic/Makefile
