Subject: [PATCH 01/36] ARM: samsung: make S3C24XX_MISCCR access indirect
Date: Thu, 10 Oct 2019 22:29:45 +0200 [thread overview]
Message-ID: <20191010203043.1241612-1-arnd@arndb.de> (raw)
Message-ID: <20191010202945.e1O-anp7-475iVTqOEmhua1NBkpVk522Y2N__6DdkPI@z> (raw)
In-Reply-To: <20191010202802.1132272-1-arnd@arndb.de>
The clk driver uses both a function call into an exported
platform file and a direct register access to a hardcoded
virtual address for accessing the MISCCR register, both
become are a problem for a multiplatform kernel because
of the header file dependency.
Make this an indirect function call through platform data
instead.
