From 77109411d5d24471ffa391dce56ba3559fb87d94 Mon Sep 17 00:00:00 2001 From: Bartlomiej Zolnierkiewicz Date: Thu, 13 Nov 2014 16:00:56 +0100 Subject: thermal: exynos: remove needless triminfo_data abstraction reg->triminfo_data is used only in exynos_tmu_initialize() and the code has already different paths for Exynos5440 and other SoC types (on which TRIMINFO_DATA register offset is identical) so the register abstraction is not needed and can be removed. There should be no functional changes caused by this patch.

Then add ->tmu_clear_irqs implementations for Exynos4210+ and Exynos5440. Finally remove no longer needed reg->tmu_int[stat,clear] abstractions and struct exynos_tmu_registers instances.
