If anyone has any objections, please let me know. ------------------ From: Tomi Valkeinen [ Upstream commit 689a54acb56858c85de8c7285db82b8ae6dbf683 ] The DPHY driver does not return the actual hs_clk_rate, so the DSI driver has no idea what clock was actually achieved. Set the realized hs_clk_rate to the opts struct, so that the DSI driver gets it back.
