-Subject: [PATCH] spi/bitbang: add support for SPI_MASTER_NO_{TX, RX} modes
-
-This patch adds a new flags argument to bitbang_txrx_be_cpha0 and
-bitbang_txrx_be_cpha1 transfer functions. This enables support for
-SPI_MASTER_NO_{TX,RX} transfer modes. The change should have no impact
-on speed of the existing drivers. bitbank_txrx_* functions are usually
-inlined into the drivers. When the argument is equal to constant zero,
-the optimizer would be able to eliminate the dead code (flags checks)
-easily. Tested on ARM and GCC 4.4.x and in all cases the checks were
-eliminated in the inlined function.
