It is a bit special > than other already supported pipelines because it has additional unit > called TCON TOP responsible for relationship configuration between > mixers, TCONs and HDMI. Additionally, it has additional gates for DSI > and TV TCONs, TV encoder clock settings and pin muxing between LCD > and TV encoders. > > However, it seems that TCON TOP will become a norm, since newer > Allwinner SoCs like H6 also have this unit. > > I tested different possible configurations: > - mixer0 <> TCON-TV0 <> HDMI > - mixer0 <> TCON-TV1 <> HDMI > - mixer1 <> TCON-TV0 <> HDMI > - mixer1 <> TCON-TV1 <> HDMI > > Please review. > > Best regards, > Jernej > > Changes from v2: > - Collected tags > - Exported drm_crtc_port_mask() symbol > - Removed TCON TOP reset name > - TCON TOP gates have now right parents > - updated TCON TOP bindings > - dropped new TCON quirk due TCON TOP rework Forgot to add: - in "drm/sun4i: Don't change clock bits in DW HDMI PHY driver" patch, only parent selection bit is reset to 0. Previously whole register was set to 0. Previous version broke H3 HDMI. > > Changes from v1: > - Split DT bindings patch and updated description > - Split HDMI PHY patch > - Move header file from TCON TOP patch to dt bindings patch > - Added Rob reviewed-by tag > - Used clk_hw_register_gate() instead of custom gate registration code > - Reworked TCON TOP to be part of of-graph. Because of that, a lot of > new patches were added. > - Droped mixer index quirk patch > - Reworked TCON support for TCON TOP > - Updated commit messages > > Jernej Skrabec (24): > clk: sunxi-ng: r40: Add minimal rate for video PLLs > clk: sunxi-ng: r40: Allow setting parent rate to display related > clocks > clk: sunxi-ng: r40: Export video PLLs > dt-bindings: display: sunxi-drm: Add TCON TOP description > drm/sun4i: Add TCON TOP driver > drm/sun4i: Fix releasing node when enumerating enpoints > drm/sun4i: Split out code for enumerating endpoints in output port > drm/sun4i: Add support for traversing graph with TCON TOP > drm/sun4i: Don't skip TCONs if they don't have channel 0 > drm/sun4i: tcon: Generalize engine search algorithm > drm/sun4i: Don't check for LVDS and RGB when TCON has only ch1 > drm/sun4i: Don't check for panel or bridge on TV TCONs > dt-bindings: display: sun4i-drm: Add R40 mixer compatibles > drm/sun4i: Add support for R40 mixers > dt-bindings: display: sun4i-drm: Add description of A64 HDMI PHY > drm/sun4i: Enable DW HDMI PHY clock > drm/sun4i: Don't change clock bits in DW HDMI PHY driver > drm/sun4i: DW HDMI PHY: Add support for second PLL > drm/sun4i: Add support for second clock parent to DW HDMI PHY clk > driver > drm/sun4i: Add support for A64 HDMI PHY > drm: of: Export drm_crtc_port_mask() > drm/sun4i: DW HDMI: Expand algorithm for possible crtcs > ARM: dts: sun8i: r40: Add HDMI pipeline > ARM: dts: sun8i: r40: Enable HDMI output on BananaPi M2 Ultra > > .../bindings/display/sunxi/sun4i-drm.txt | 62 +++- > .../boot/dts/sun8i-r40-bananapi-m2-ultra.dts | 45 +++ > arch/arm/boot/dts/sun8i-r40.dtsi | 269 ++++++++++++++++ > drivers/clk/sunxi-ng/ccu-sun8i-r40.c | 58 ++-- > drivers/clk/sunxi-ng/ccu-sun8i-r40.h | 8 +- > drivers/gpu/drm/drm_of.c | 5 +- > drivers/gpu/drm/sun4i/Makefile | 3 +- > drivers/gpu/drm/sun4i/sun4i_drv.c | 121 +++++-- > drivers/gpu/drm/sun4i/sun4i_tcon.c | 66 ++-- > drivers/gpu/drm/sun4i/sun8i_dw_hdmi.c | 46 ++- > drivers/gpu/drm/sun4i/sun8i_dw_hdmi.h | 8 +- > drivers/gpu/drm/sun4i/sun8i_hdmi_phy.c | 54 +++- > drivers/gpu/drm/sun4i/sun8i_hdmi_phy_clk.c | 90 ++++-- > drivers/gpu/drm/sun4i/sun8i_mixer.c | 24 ++ > drivers/gpu/drm/sun4i/sun8i_tcon_top.c | 300 ++++++++++++++++++ > drivers/gpu/drm/sun4i/sun8i_tcon_top.h | 40 +++ > include/drm/drm_of.h | 8 + > include/dt-bindings/clock/sun8i-r40-ccu.h | 4 + > include/dt-bindings/clock/sun8i-tcon-top.h | 11 + > 19 files changed, 1100 insertions(+), 122 deletions(-) > create mode 100644 drivers/gpu/drm/sun4i/sun8i_tcon_top.c > create mode 100644 drivers/gpu/drm/sun4i/sun8i_tcon_top.h > create mode 100644 include/dt-bindings/clock/sun8i-tcon-top.h -- To unsubscribe from this list: send the line "unsubscribe devicetree" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
