[PATCH 02/11] OMAP2/3: UART: add omap_hwmod data for UARTs 1-4

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



From: Kevin Hilman <khilman@xxxxxxxxxxxxxxxxxxx>

This patch adds omap_hwmod data for UARTs on OMAP2 and OMAP3
platforms.

UART4 support for 3630 and OMAP2 hwmod data added by Govindraj R.
