Philipp Tomsich 7e0e5c552f rockchip: spi: only wait for completion, if transmitting ... The logic in the main transmit loop took a bit of reading the TRM to fully understand (due to silent assumptions based in internal logic): the "wait until idle" at the end of each iteration through the loop is required for the transmit-path as each clearing of the ENA register (to update run-length in the CTRLR1 register) will implicitly flush the FIFOs... transmisson can therefore not overlap loop iterations. This change adds a comment to clarify the reason/need for waiting until the controller becomes idle and wraps the entire check into an 'if (out)' to make it clear that this is required for transfers with a transmit-component only (for transfers having a receive-component, completion of the transmit-side is trivially ensured by having received the correct number of bytes). The change does not increase execution time measurably in any of my tests. Signed-off-by: Philipp Tomsich <philipp.tomsich@theobroma-systems.com>		2019-05-01 00:00:04 +02:00
