Hi, I would like to integrate the upstream devicetree ath79-spi patches into the ar71xx tree. But there are some improvements upstream which conflicts to use, they dropped the spi_controller_data, which is used by some boards to define the type of chip select. The type is internal or gpio. The internal chip selects are routed to gpios in the end.
Is there a notable difference between the internal chip select and the direct accessed gpio variant? Did someone any performance tests on this? Best, lynxis -- Alexander Couzens mail: [email protected] jabber: [email protected] mobile: +4915123277221
