Second AMD graphics card no long detected by xrandr --listproviders

After updating, probably the kernel or the amd drivers, the second card is no longer shown by xrandr.

I have two cards and would like to use both of them.

lspci | grep VGA
01:00.0 VGA compatible controller: Advanced Micro Devices, Inc. [AMD/ATI] Oland [Radeon HD 8570 / R7 240/340 OEM]
06:00.0 VGA compatible controller: Advanced Micro Devices, Inc. [AMD/ATI] Oland [Radeon HD 8570 / R7 240/340 OEM]

so lspci shows both cards, however xrandr

xrandr --listproviders
Providers: number : 1
Provider 0: id: 0x53 cap: 0xf, Source Output, Sink Output, Source Offload, Sink Offload crtcs: 2 outputs: 2 associated providers: 0 name:radeon

no longer shows the second provider. This used to have two and I could set up the second monitor using `xrandr --setprovideroutputsource 1 0` but this no longer works.

Anyone have an idea of what changed in xorg or radeon which may have broke this?
