C++ (Cpp) tx_max Examples

Example #1

File: spi-rockchip-core.c Project: lgeek/linux-tronsmart-orion-r28

static void dw_writer(struct dw_spi *dws)
{
	u32 max = tx_max(dws);
	u16 txw = 0;	
	
	DBG_SPI("%dbyte tx:",dws->n_bytes);
	while (max--) {
		/* Set the tx word if the transfer's original "tx" is not null */
		if (dws->tx_end - dws->len) {
			if (dws->n_bytes == 1)
			{
				txw = *(u8 *)(dws->tx);	
				DBG_SPI("0x%02x,", *(u8 *)(dws->tx));
			}
			else
			{
				txw = *(u16 *)(dws->tx);
				DBG_SPI("0x%02x,", *(u16 *)(dws->tx));
			}
		}
		dw_writew(dws, SPIM_TXDR, txw);
		dws->tx += dws->n_bytes;
	}
	
	//it is neccessary
	wait_till_not_busy(dws);
	
	DBG_SPI("\n");
}

		writel_relaxed(txw, rs->regs + ROCKCHIP_SPI_TXDR);
		rs->tx += rs->n_bytes;
