Kconfig defines the value of PANEL_LCD to be 1 if we select custom configuration but in the code LCD_TYPE_CUSTOM is defined as 5. my hardware is LCD_TYPE_CUSTOM, but the pins were assigned to it as pins of LCD_TYPE_OLD, and it was not working. Now values are corrected with referenece to the values defined in Kconfig and it is working. checked on JHD204A lcd with LCD_TYPE_CUSTOM configuration.
