Subject: [U-Boot] [PATCH 02/11] sunxi: Add I2C_SUN6I_P2WI kconfig entry
Date: Tue,  6 Feb 2018 20:45:19 +0530	[thread overview]
Message-ID: <1517930128-26181-3-git-send-email-jagan@amarulasolutions.com> (raw)
In-Reply-To: <1517930128-26181-1-git-send-email-jagan@amarulasolutions.com>

Add simple and meaningful kconfig option for p2wi.c
instead of using MACH type on Makefile.

p2wi is an I2C controller, so used the same on kconfig
definition.
