For the serial subsystem, it makes sense to have a different number of clients capable of input and output: not all clients which are capable of output will need input. Prior to this PR, there was a
SERIAL_NUM_CLIENTSmacro, as well as aSERIAL_TX_ONLYmacro which indicated whether or not serial input was required (e.g. whether the driver enabled RX IRQs, or if an RX virtualiser is necessary).I believe it makes more sense to instead have a separate count for each functionality, as for example it is plausible that a system may have only 1 client with input enabled, and more than 1 with output enabled.
This PR essentially turns the
SERIAL_NUM_CLIENTSandSERIAL_TX_ONLYmacros into theSERIAL_NUM_TX_CLIENTSandSERIAL_NUM_RX_CLIENTSmacros, in preparation for the tooling supporting specification for each client whether TX and/or RX are enabled.Merge after #301.
