The ZL8802 support was tested using a Flex BMR469 converter module, the ZLS1003 with a Flex BMR466 and the ZLS4009 with a Flex BMR465. The documentation is updated with new sysfs attribute descriptions and broken links to technical specifications has been fixed. Also the Renesas company name was added and Ericsson changed to Flex to reflect new ownership relations.
