Subject: [PATCH v2 34/41] cpufreq: s3c24xx: split out registers
Date: Thu, 6 Aug 2020 20:20:51 +0200 [thread overview]
Message-ID: <20200806182059.2431-34-krzk@kernel.org> (raw)
In-Reply-To: <20200806181932.2253-1-krzk@kernel.org>
From: Arnd Bergmann <arnd@arndb.de>
Each of the cpufreq drivers uses a fixed set of register
bits, copy those definitions into the drivers to avoid
including mach/regs-clock.h.
Signed-off-by: Arnd Bergmann <arnd@arndb.de>
[krzk: Fix build by copying also S3C2410_LOCKTIME]
Signed-off-by: Krzysztof Kozlowski <krzk@kernel.org>
---
Changes since v1:
1. Copy also S3C2410_LOCKTIME to the driver.
