ata: pata_of_platform: Allow to use 16-bit wide data transfer
In some cases, the system bus can be configured for 16-bit mode, in this case using read/write functions for 32-bit values results in two cycles of 16 bits each, which is wrong. This patch adds the devicetree flag to switch the driver to use 16-bit mode for I/O transfers. Acked-by:Bartlomiej Zolnierkiewicz <b.zolnierkie@samsung.com> Signed-off-by:
