From: Tomasz Figa Date: Mon, 17 Mar 2014 22:28:09 +0000 (+0900) Subject: ARM: SAMSUNG: Add soc_is_s3c2410() helper X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=04241069617d4f0bfd9f4a3aeefae13e1e5b55e1;p=GitHub%2Fmoto-9609%2Fandroid_kernel_motorola_exynos9610.git ARM: SAMSUNG: Add soc_is_s3c2410() helper Due to the S3C2410 SoC being quite different from other S3C24xx SoCs in some aspects, such as availability of DIVSLOT register in its UART blocks, there is a need sometimes to check whether we are running on this SoC, not just the S3C24xx series. This patch adds soc_is_s3c2410() helper function for this purpose.
