Subject: [PATCH v2 15/33] thermal: exynos: remove TMU_SUPPORT_TRIM_RELOAD flag
Date: Thu, 13 Nov 2014 16:01:10 +0100
Message-id: <1415890888-8881-16-git-send-email-b.zolnierkie@samsung.com>
In-reply-to: <1415890888-8881-1-git-send-email-b.zolnierkie@samsung.com>
References: <1415890888-8881-1-git-send-email-b.zolnierkie@samsung.com>
Sender: linux-kernel-owner@vger.kernel.org

Replace TMU_SUPPORT_TRIM_RELOAD flag check in exynos_tmu_initialize()
by an explicit check for a SoC type (only Exynos3250, Exynos4412 and
Exynos5250 have TMU_SUPPORT_READY_STATUS flag set in their struct
exynos_tmu_init_data instances).  Please note that this requires
adding separate SoC type for Exynos5420 so it doesn't get mistaken
with Exynos5250.

This is a preparation for introducing per-SoC type tmu_initialize
method.

There should be no functional changes caused by this patch.
