Subject: [PATCH v2 2/2] arm: samsung: Remove HAVE_S3C2410_I2C and use direct dependencies
Date: Sun, 21 Nov 2021 17:05:58 +0200 [thread overview]
Message-ID: <20211121150558.21801-2-semen.protsenko@linaro.org> (raw)
In-Reply-To: <20211121150558.21801-1-semen.protsenko@linaro.org>
A separate Kconfig option HAVE_S3C2410_I2C for Samsung SoCs is not
really needed and the i2c-s3c24xx driver can depend on Samsung ARM
architectures instead. This also enables i2c-s3c2410 for arm64 Exynos
SoCs, which is required for example by Exynos850.
This is basically continuation of work made in following commits:
- commit d96890fca9fd ("rtc: s3c: remove HAVE_S3C_RTC in favor of
direct dependencies")
- commit 7dd3cae90d85 ("ARM: samsung: remove HAVE_S3C2410_WATCHDOG and
use direct dependencies")
