Subject: [rtc-linux] [Patch] rtc: rtc-ds1307: enable support for mcp794xx as a wakeup source without IRQ
Date: Sat, 22 Apr 2017 18:28:00 +0100 [thread overview]
Message-ID: <20170422182800.460265ba@pixelzero> (raw)
This patch extends the fixes for ds1337, ds1339, ds3231 in 8bc2a40730ec
to mcp794xx devices, so that those parts can similarly be used as a wakeup
source without an IRQ to the processor.
Tested on Raspberry Pi ZeroW with MCP79400.
Signed-off-by: David Lowe <dave-lowe@ntlworld.com>
