[PATCH v2 6/9] ARM: DRA7: hwmod: Do not register RTC on DRA71
From: Lokesh Vutla <hidden>
Date: 2016-10-21 10:38:38
Also in:
linux-arm-kernel, linux-omap
Subsystem:
arm port, omap hwmod data, omap2+ support, the rest · Maintainers:
Russell King, Paul Walmsley, Aaro Koskinen, Andreas Kemnade, Kevin Hilman, Roger Quadros, Tony Lindgren, Linus Torvalds
From: Nishanth Menon <redacted> RTC is not available on DRA71x, so accessing any of the RTC register or clkctrl register will lead to a crash. So, do not register RTC hwmod for DRA71x.
