drm/sun4i: fix unmet dependency on RESET_CONTROLLER for PHY_SUN6I_MIPI_DPHY

2021-11-15T09:52:03+00:00

When PHY_SUN6I_MIPI_DPHY is selected, and RESET_CONTROLLER is not selected, Kbuild gives the following warning: WARNING: unmet direct dependencies detected for PHY_SUN6I_MIPI_DPHY Depends on [n]: (ARCH_SUNXI [=n] || COMPILE_TEST [=y]) && HAS_IOMEM [=y] && COMMON_CLK [=y] && RESET_CONTROLLER [=n] Selected by [y]: - DRM_SUN6I_DSI [=y] && HAS_IOMEM [=y] && DRM_SUN4I [=y] This is because DRM_SUN6I_DSI selects PHY_SUN6I_MIPI_DPHY without selecting or depending on RESET_CONTROLLER, despite PHY_SUN6I_MIPI_DPHY depending on RESET_CONTROLLER. These unmet dependency bugs were detected by Kismet, a static analysis tool for Kconfig. Please advise if this is not the appropriate solution. v2: Fixed indentation to match the rest of the file.

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/sun4i: dw-hdmi: Make use of the helper function dev_err_probe()

2021-09-16T13:47:20+00:00

When possible use dev_err_probe help to properly deal with the PROBE_DEFER error, the benefit is that DEFER issue will be logged in the devices_deferred debugfs file. And using dev_err_probe() can reduce code size, the error value gets printed.

drm/sun4i: Fix macros in sun8i_csc.h

2021-09-01T09:44:10+00:00

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/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
