Prado <nfraprado@collabora.com> Since this is hw managed, it's a good idea to add CLK_IGNORE_UNUSED to this clock's flags to avoid potential lockups at boot. Please add that flag. Cheers, Angelo

Add the CLK_VDEC_ACTIVE clock to the vdec clock driver. This clock is enabled by the VPU once it starts decoding. Signed-off-by: Nícolas F. R. A.
