Heiner Kallweit 7ba2f2757d spi: core: add hook flash_read_supported to spi_master ... If hook spi_flash_read is implemented the fast flash read feature is enabled for all devices attached to the respective master. In most cases there is just one flash chip, however there are also devices with more than one flash chip, namely some WiFi routers. Then the fast flash read feature can be used for the first chip only. OpenWRT implemented an own handling of this case, using controller_data element of spi_device to hold the information whether fast flash read can be used for a device. This patch adds hook flash_read_supported to spi_master which is used to extend spi_flash_read_supported() by checking whether the fast flash read feature can be used for a specific spi_device. If the hook is not implemented the default behavior is to allow fast flash read for all devices (if spi_flash_read is implemented).
