Currently with 3528 i got state where hdmi phy drives correct mode but screen is black (as no vop3 correct support to drive working dw_hdmi) If you will hint me what needs to be changed in yours 3576 vop2 series to get basic vop3 working - i can play with this on my two 3528 devices…. (we can skip all fancy vop3 features; it will be ehough to see prompt + basic cooperation with 3528 mali gpu)

The interface mux and irq are like rk3568/88 The overlay are similar with rk3576. I think you can use this series as a reference to add baseic support for rk3528. > > > >_______________________________________________ >Linux-rockchip mailing list >Linux-rockchip@lists.infradead.org >http://lists.infradead.org/mailman/listinfo/linux-rockchip
From: Andy Yan <andy.yan@rock-chips.com> Thanks for the basic work from Collabora, I can bringup a HDMI display out on rk3576. This patch series are still in a very early stage, some architectural adjustments and more self test are needed, I plan to add some SOC specific callbacks in next version. I'm sending it out at this moment just want to facilitate some people who are looking forward to doing early try. The hdmi depends on WIP patch from Cristian[0] I only test it with a 1080P HDMI output with linux kernel boot logo and a weston output. If there are some one want to have a try, I have a tree here[0] [0]https://lore.kernel.org/lkml/20240819-b4-rk3588-bridge-upstream-v4-0-6417c72a2749@collabora.com/ [1]https://github.com/andyshrk/linux/tree/rk3576-vop2-upstream-v1-0827 Andy Yan (5): drm/rockchip: vop2: Add debugfs support drm/rockchip: vop2: Support for different layer selet configuration between VPs drm/rockchip: vop2: Add support for rk3576 phy: phy-rockchip-samsung-hdptx: Don't request RST_PHY/RST_ROPLL/RST_LCPLL drm/rockchip: Add basic RK3576 HDMI output support .../gpu/drm/rockchip/dw_hdmi_qp-rockchip.c | 174 ++++- drivers/gpu/drm/rockchip/rockchip_drm_vop2.c | 656 +++++++++++++++++- drivers/gpu/drm/rockchip/rockchip_drm_vop2.h | 99 ++- drivers/gpu/drm/rockchip/rockchip_vop2_reg.c | 496 ++++++++++++- .../phy/rockchip/phy-rockchip-samsung-hdptx.c | 17 +- 5 files changed, 1341 insertions(+), 101 deletions(-)
