After fixed it, > you can use my Reviewed-by :) Right, I had marked Jacopo's VIN clock patch for application to renesas-clk-for-v5.11, but haven't actually done that, only in my local tree. But probably it does make sense to reorder the patches, and apply the GPIO one first. > >@@ -180,6 +181,10 @@ static const struct mssr_mod_clk r8a779a0_mod_clks[] __initconst = { > > DEF_MOD("vin35", 827, R8A779A0_CLK_S1D1), > > DEF_MOD("vin36", 828, R8A779A0_CLK_S1D1), > > DEF_MOD("vin37", 829, R8A779A0_CLK_S1D1), Gr{oetje,eeting}s, Geert

Add the module clocks used by the Pin Function Controller (PFC) and General Purpose Input/Output (GPIO) blocks, and their parent clock CP. Signed-off-by: Geert Uytterhoeven <geert+renesas@glider.be> --- Untested on actual hardware. Note that the BSP uses MAIN instead of EXTAL, just like for the CBFUSA clock. However, according to Figure 8.1.1 ("Block Diagram of CPG (R-Car V3U-AD)") in the R-Car V3U Series User's Manual Rev. 0.5, the parent of the CP clock is EXTAL, which matches earlier R-Car Gen3 SoCs. --- drivers/clk/renesas/r8a779a0-cpg-mssr.c | 5 +++++ 1 file changed, 5 insertions(+)
