From: Afzal Mohammed Date: Sat, 12 Oct 2013 10:15:26 +0000 (+0530) Subject: ARM: OMAP2+: hwmod: AM335x: runtime register update X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=1c7e224d;p=GitHub%2Fmoto-9609%2Fandroid_kernel_motorola_exynos9610.git ARM: OMAP2+: hwmod: AM335x: runtime register update Most of IP's in AM335x is present on AM43x and so in those cases both will use same hwmod database (except for a few cases where clock related details differ), but there is difference w.r.t register offset between these. Update register offsets at runtime based on the SoC detected to help in sharing otherwise same hwmod.
