This patch converts mxs_spi driver to support DM/DTS.

Signed-off-by: Lukasz Majewski lukma@denx.de

---

Changes in v4: - Adjust the driver to support i.MX23 (add compatible, adjust clk code) - Use BIT() macro where applicable

Changes in v3: - Set more appropriate tags

Changes in v2: - New patch (conversion of mxs_spi.c to DM_SPI)
