The Seeed Odyssey-STM32MP157C board has a 20-pin DVP camera output. The DCMI pins used on this output are defined in the pin state definition &pinctrl/dcmi-1, AKA &dcmi_pins_b (added in mainline commit 02814a41529a55dbfb9fbb2a3728e78e70646ea6). Set these pins as the default pinctrl of the DCMI peripheral in the board device tree. The pins are not used for any other purpose, so it seems safe to assume most users will not need to override (delete) what this patch provides. status defaults to "disabled", so the peripheral will not be unnecessarily started. And the users who actually intend to make use of a camera on the DVP port will have this little part of the configuration ready. Signed-off-by: Grzegorz Szymaszek <redacted>
