[PATCH 1/4] mfd: exynos-lpass: Enable UART module support

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

 



From: Beomho Seo <beomho.seo@xxxxxxxxxxx>

This patch enables support for UART module in Exynos Audio SubSystem.
There are boards (for example TM2), which use it for communication with
bluetooth chip.
