Subject: [PATCH v2 0/3] ARM: meson: Add reset controller
Date: Tue, 14 Oct 2014 20:35:46 +0200	[thread overview]
Message-ID: <1413311749-13948-1-git-send-email-carlo@caione.org> (raw)

Apparently several IPs found in the MesonX SoCs can be reset by programming a
specific bit in a register in the so called AO (Always-On) domain. From the
documentation released by Amlogic under NDA it is not clear which devices can
be reset acting on this register. So far from the sources release by Amlogic it
seems that at least two IPs use this register for reset: RTC and UART. Since I
need it to reset the RTC, I wrote this small driver.

v2:
* removed useless comment
* added platform_get_drvdata
* removed owner field
