I'm not sure I don't prefer the version with one writeb() call.
How about:
writeb(spi->tx_buf ? *spi->tx_buf++ : 0xaa,
spi->regs + MCHP_CORESPI_REG_TXDATA);
Please don't abuse the ternery operator like this, just write normal
conditional statements.
FWIW, that's what my patch does already :-)

Hi Andy,

Thanks for the series. However, this particular patch appears to
introduce a regression. The SPI controller reads an incorrect
Device ID from the peripheral.

I’m investigating the root cause and will follow up.

Best regards,
Prajna
