Subject: [PATCH v2 00/10] i.MX reset reason detection support
Date: Fri, 20 Apr 2018 18:05:28 -0700	[thread overview]
Message-ID: <20180421010538.16488-1-andrew.smirnov@gmail.com> (raw)

Everyone:

This patchset is the result of my work on adding support for detecting
and reporting reset reason as can be obtained from System Reset
Controller (to be more precise via SRSR register) on i.MX family of
SoC.

Currently list of supported SoC is as follows:

	  - i.MX6 (tested on i.MX6Q)
	  - i.MX7 (tested on i.MX7D)
	  - VFxxx (tested on VF610)


Changes since [v1]:

	- i.MX reset reason detection code was converted to do detect
          the source with bitmasking as opposed to having a switch
          statement, due to potential problems with the latter as was
          pointed out by Philipp in [thread1]

	- Change above also allowed to unify VFxxx and i.MX codepaths
          without the need to introduce a dedicated VFxxx centric
          function

[v1] http://lists.infradead.org/pipermail/barebox/2018-April/032614.html
[thread1] http://lists.infradead.org/pipermail/barebox/2018-April/032708.html

Feedback is wellcome!

Thanks,
Andrey Smirnov
