Subject: [PATCH 0/3] keep console alive even if missing the 'enable' clock
Date: Mon, 26 Aug 2019 15:29:26 +0800 [thread overview]
Message-ID: <20190826072929.7696-1-zhang.lyra@gmail.com> (raw)
From: Chunyan Zhang <chunyan.zhang@unisoc.com>
After the commit 4007098f4ce4 (serial: sprd: Add power management for the Spreadtrum serial controller),
the 'enable' clock was forced to be configured in device tree, otherwise the uart devices couldn't be
probed successfully.
With this patch-set, the uart device which is used as console would be allowed to register even without
any clock configured in device tree, this will make debug easier.
Chunyan Zhang (3):
serial: sprd: check the right port and membase
serial: sprd: add console_initcall in sprd's uart driver
serial: sprd: keep console alive even if missing the 'enable' clock
