On AM62x devices, main ESM error event outputs can be routed to MCU ESM as inputs. So, two ESM device nodes are expected in the device tree : one for main ESM and another one for MCU ESM. MCU ESM error output can trigger the reset logic to reset the device when CTRLMMR_MCU_RST_CTRL:MCU_ESM_ERROR_RESET_EN_Z is set to '0'. Signed-off-by: Julien Panis <jpanis@baylibre.com>
