What's different this time? Have you, for instance, done more thorough testing, to show that the logical parent structure this driver outputs is actually what the hardware is doing? I think maybe this would qualify as: Fixes: 3bd14ae9da91 ("clk: rockchip: fix incorrect parent for rk3399's {c,g}pll_aclk_perihp_src") The above is not exactly a pure regression (we really want both changes), but apparently it wasn't a complete fix. > Signed-off-by: Xing Zheng > --- > > Changes in v2: None Uhh, isn't this patch brand new in v2? I don't think that means "Changes ... None".
