Subject: [PATCH 16/22] ARM: omap1: move clk support into a single file
Date: Thu, 8 Aug 2019 23:41:26 +0200 [thread overview]
Message-ID: <20190808214232.2798396-2-arnd@arndb.de> (raw)
In-Reply-To: <20190808214232.2798396-1-arnd@arndb.de>
The omap1 clock support is traditionally split into the clock.c,
clock_data.c and opp_data.c files. As a preparation for cleaning
this up, move everything into one file.
No functional change, each added line comes from an existing file.
Signed-off-by: Arnd Bergmann <arnd@arndb.de>

Subject: [PATCH 16/22] ARM: omap1: move clk support into a single file
Date: Thu, 8 Aug 2019 23:41:26 +0200 [thread overview]
Message-ID: <20190808214232.2798396-2-arnd@arndb.de> (raw)
In-Reply-To: <20190808214232.2798396-1-arnd@arndb.de>
The omap1 clock support is traditionally split into the clock.c,
clock_data.c and opp_data.c files. As a preparation for cleaning
this up, move everything into one file.
No functional change, each added line comes from an existing file.

Subject: [PATCH 16/22] ARM: omap1: move clk support into a single file
Date: Thu, 8 Aug 2019 23:41:26 +0200 [thread overview]
Message-ID: <20190808214232.2798396-2-arnd@arndb.de> (raw)
In-Reply-To: <20190808214232.2798396-1-arnd@arndb.de>
The omap1 clock support is traditionally split into the clock.c,
clock_data.c and opp_data.c files. As a preparation for cleaning
this up, move everything into one file.
No functional change, each added line comes from an existing file.
Signed-off-by: Arnd Bergmann <arnd@arndb.de>
