drm/sun4i: Fix macros in sun8i_csc.h

2021-11-18T18:17:20+00:00

commit c302c98da646409d657a473da202f10f417f3ff1 upstream. Macros SUN8I_CSC_CTRL() and SUN8I_CSC_COEFF() don't follow usual recommendation of having arguments enclosed in parenthesis. While that didn't change anything for quite sometime, it actually become important after CSC code rework with commit ea067aee45a8 ("drm/sun4i: de2/de3: Remove redundant CSC matrices"). Without this fix, colours are completely off for supported YVU formats on SoCs with DE2 (A64, H3, R40, etc.). Fix the issue by enclosing macro arguments in parenthesis.

drm/sun4i: dw-hdmi: Fix HDMI PHY clock setup

2021-10-06T09:05:44+00:00

Recent rework, which made HDMI PHY driver a platform device, inadvertely reversed clock setup order. HW is very touchy about it. Proper way is to handle controllers resets and clocks first and HDMI PHYs second. Currently, without this fix, first mode set completely fails (nothing on HDMI monitor) on H3 era PHYs. On H6, it still somehow work. Move HDMI PHY reset & clocks handling to sun8i_hdmi_phy_init() which will assure that code is executed after controllers reset & clocks are handled. Additionally, add sun8i_hdmi_phy_deinit() which will deinit them at controllers driver unload. Tested on A64, H3, H6 and R40.

drm/bridge: Centralize error message when bridge attach fails

2021-07-28T13:33:12+00:00

Being informed of a failure to attach a bridge is useful, and many drivers prints an error message in that case. Move the message to drm_bridge_attach() to avoid code duplication. Suggested-by: Stephen Boyd Signed-off-by: Laurent Pinchart Reviewed-by: Tomi Valkeinen Reviewed-by: Jyri Sarha

drm/aperture: Pass DRM driver structure instead of driver name

2021-07-01T09:11:55+00:00

Print the name of the DRM driver when taking over fbdev devices. Makes the output to dmesg more consistent. Note that the driver name is only used for printing a string to the kernel log.

drm/sun4i: dw-hdmi: Make HDMI PHY into a platform device

2021-06-07T11:41:31+00:00

On sunxi boards that use HDMI output, HDMI device probe keeps being avoided indefinitely with these repeated messages in dmesg: platform 1ee0000.hdmi: probe deferral - supplier 1ef0000.hdmi-phy not ready There's a fwnode_link being created with fw_devlink=on between hdmi and hdmi-phy nodes, because both nodes have 'compatible' property set. Fw_devlink code assumes that nodes that have compatible property set will also have a device associated with them by some driver eventually. This is not the case with the current sun8i-hdmi driver. This commit makes sun8i-hdmi-phy into a proper platform device and fixes the display pipeline probe on sunxi boards that use HDMI.

drm/sun4i: de3: Be explicit about supported modifiers

2021-06-07T11:33:46+00:00

Currently only linear formats are supported in sun4i-drm driver, but SoCs like H6 supports AFBC variant of some of them in multiple cores (GPU, VPU, DE3). Panfrost already implements AFBC compression and is sometimes confused what should be default choice (linear, AFBC) if DRM driver is not explicit about modifier support (MiniMyth2 distro with MythTV app). After some discussion with Daniel Stone on #panfrost IRC, it was decided to make modifiers in sun4i-drm explicit, to avoid any kind of guessing, not just in panfrost, but everywhere. In fact, long term idea is to make modifier parameter in drm_universal_plane_init() mandatory (non NULL).
