drm/sun4i: Allow building on arm64

2018-03-02T07:46:14Z

64-bit ARM SoCs from Allwinner have DE2/TCON/HDMI periphery which is compatible to 32-bit SoCs, so allow building DRM driver for arm64 architecture.

drm/sun4i: Implement A83T HDMI driver

2018-02-16T08:38:30Z

A83T has DW HDMI IP block with a custom PHY similar to Synopsys gen2 HDMI PHY. Only video output was tested, while HW also supports audio and CEC. Support for them will be added later.

drm/sun4i: cec: Enable back CEC-pin framework

2017-09-22T06:42:17Z

Now that the cec-pin framework has been merged, we can remove the safeguard that were preventing the CEC part of the sun4i HDMI driver and actually start to use it. Signed-off-by: Hans Verkuil Signed-off-by: Maxime Ripard

sun4i_hdmi: add CEC support

2017-07-18T16:27:50Z

Add HDMI CEC support to the Allwinner A10 SoC. This SoC uses a poor-man's CEC implementation by polling the CEC pin. It is using the CEC_PIN core implementation for such devices to do the heavy lifting. It just provides the callbacks to read/drive the CEC pin.

drm/sun4i: Add if statement instead of depends on

2017-07-18T14:52:41Z

The depends on relationship is obvious, and using an if statement will propagate it to every option without the need for each and every one of them to define it. Reviewed-by: Chen-Yu Tsai Signed-off-by: Maxime Ripard

drm/sun4i: Add HDMI support

2017-06-01T07:50:01Z

The earlier Allwinner SoCs (A10, A10s, A20, A31) have an embedded HDMI controller. That HDMI controller is able to do audio and CEC, but those have been left out for now. Reviewed-by: Chen-Yu Tsai Signed-off-by: Maxime Ripard

drm/sun4i: add support for Allwinner DE2 mixers

2017-06-01T07:49:54Z

Allwinner have a new "Display Engine 2.0" in their new SoCs, which comes with mixers to do graphic processing and feed data to TCON, like the old backends and frontends. Add support for the mixer on Allwinner V3s SoC; it's the simplest one. Currently a lot of functions are still missing -- more investigations are needed to gain enough information for them.

drm/sun4i: add a Kconfig option for sun4i-backend

2017-06-01T07:49:54Z

As sun4i-backend is now a dedicated module, add an Kconfig option for it to make it optional, since some build may only use other engines. Signed-off-by: Icenowy Zheng Signed-off-by: Maxime Ripard

drm/sun4i: add COMMON_CLK dependency

2016-05-30T06:28:33Z

The sun4i drm driver uses the clk-provider interfaces, which are not available when CONFIG_COMMON_CLK is disabled: drivers/gpu/drm/sun4i/sun4i_dotclock.c:19:16: error: field 'hw' has incomplete type struct clk_hw hw; In file included from ../include/asm-generic/bug.h:13:0, from ../arch/arm/include/asm/bug.h:59, from ../include/linux/bug.h:4, from ../include/linux/io.h:23, from ../include/linux/clk-provider.h:14, from ../drivers/gpu/drm/sun4i/sun4i_dotclock.c:13: drivers/gpu/drm/sun4i/sun4i_dotclock.c: In function 'hw_to_dclk': include/linux/kernel.h:831:48: error: initialization from incompatible pointer type [-Werror=incompatible-pointer-types] ... This adds a Kconfig dependency to prevent the driver from being enabled in this case.

drm: Add Allwinner A10 Display Engine support

2016-04-28T08:30:05Z

The Allwinner A10 and subsequent SoCs share the same display pipeline, with variations in the number of controllers (1 or 2), or the presence or not of some output (HDMI, TV, VGA) or not. Add a driver with a limited set of features for now, and we will hopefully support all of them eventually Reviewed-by: Boris Brezillon Signed-off-by: Maxime Ripard
