8974 and friends seem to bind it to the GDSC

although on msm-3.4:

arch/arm/mach-msm/clock-8974.c
4197:static struct branch_clk mdss_mdp_lut_clk = {
4203:           .dbg_name = "mdss_mdp_lut_clk",
4205:           CLK_INIT(mdss_mdp_lut_clk.c),
4609:   {&mdss_mdp_lut_clk.c,                   MMSS_BASE, 0x0015},
5118:   CLK_LOOKUP("lut_clk", mdss_mdp_lut_clk.c, "mdp.0"),
5387:   CLK_LOOKUP("lut_clk", mdss_mdp_lut_clk.c, "fd8c2304.qcom,gdsc"
