I don't see how this patch could introduce such regression, as all the
affected registers seem to be properly reconfigured in fimd_win_commit()
anyway.
IMHO instead of reverting the patch, this issue should be investigated
and fixed properly.

I am looking at the problem, it is quite strange as it happens only on
one of two targets I have access to. Anyway it seems that something
should be added to fimd initialization sequence if we want to remove hw
accessing code from probe.

The problem is that fimd does not clear unused windows.
Simple patch which helps:
diff --git a/drivers/gpu/drm/exynos/exynos_drm_fimd.c
b/drivers/gpu/drm/exynos/exynos_drm_fimd.c
index 2ec634f..b58fce2 100644
--- a/drivers/gpu/drm/exynos/exynos_drm_fimd.c
+++ b/drivers/gpu/drm/exynos/exynos_drm_fimd.c
@@ -741,6 +741,8 @@ static void fimd_apply(struct exynos_drm_manager *mgr)
win_data = &ctx->win_data[i];
if (win_data->enabled)
fimd_win_commit(mgr, i);
+ else
+ fimd_win_disable(mgr, i);
}
fimd_commit(mgr);
But I am not fully familiar with window management code, so I do not
know if it does not breaks other stuff.

The patch disables non-enabled HW windows on applying
configuration, it will allow to clear windows enabled
by bootloader.

In my humble opinion, the patch is required to modify like below:
+ ret = pm_runtime_get_sync(ctx->dev);
+ if (ret < 0) {
When the bootloader enabled FIMD to show logo(boot image) or animation,
this function pm_runtime_get_sync() in fimd_bind() would return 1.

That issue would be because your boot-loader enabled a hardware overlay
but kernel driver enables another hardware overlay, which would also be
why it happens only on one target of your targets, and why it works
correctly by cleaning hardware overlays at fimd probe.

No, it should work correctly as is because fimd overlays will be
reconfigured at booting time by register_framebuffer() if console
framebuffer is enabled. Otherwise, a master process, X or Weston, will
reconfigure fimd overlays after kernel booting.
