Stefan Roese c032174f82 spi: kirkwood_spi.c: Some fixes and cleanup ... This patch introduces the clrsetbits_le32() accessor functions in the kirkwood SPI driver. Note that it also includes a fix: - writel(~KWSPI_CSN_ACT | KWSPI_SMEMRDY, &spireg->ctrl); + writel(KWSPI_SMEMRDY, &spireg->ctrl); Here the bit KWSPI_CSN_ACT (0x1) should have been cleared. Instead 0xfffffffe is written into this control register. This is the main reason to use the clrsetbits() functions now. As they make clearing bits much less error prone. Additionally KWSPI_IRQUNMASK is not used in spi_cs_activate() and spi_cs_deactivate() any more. Its the wrong macro but has the same value as the correct one (KWSPI_CSN_ACT). This is in preparation for use of this driver on the Marvell Armada XP platform as well.
