This makes sure the clock tree setup for the dphy is not dependent on other components. Without this change bringing up the display can fail like kernel: phy phy-30a00300.dphy.2: Invalid CM/CN/CO values: 165/217/1 kernel: phy phy-30a00300.dphy.2: for hs_clk/ref_clk=451656000/593999998 ~ 165/217 if LCDIF doesn't set up that part of the clock tree first. This was noticed when testing the Librem 5 devkit with defconfig. It doesn't happen when modules are built in. Signed-off-by: Guido Günther <agx@sigxcpu.org>
Applied, thanks. _______________________________________________ linux-arm-kernel mailing list linux-arm-kernel@lists.infradead.org http://lists.infradead.org/mailman/listinfo/linux-arm-kernel
