From: Bartlomiej Zolnierkiewicz Date: Thu, 13 Nov 2014 15:01:23 +0000 (+0100) Subject: thermal: exynos: remove TMU_SUPPORT_ADDRESS_MULTIPLE flag X-Git-Url: http://git.cdn.openwrt.org/?a=commitdiff_plain;h=56adb9efeb8115d2a3a807d84a0d037398588911;p=openwrt%2Fstaging%2Fblogic.git thermal: exynos: remove TMU_SUPPORT_ADDRESS_MULTIPLE flag Replace TMU_SUPPORT_ADDRESS_MULTIPLE flag check in exynos_map_dt_data() by an explicit check for a SoC type (only Exynos5420 with TRIMINFO quirk and Exynos5440 have TMU_SUPPORT_ADDRESS_MULTIPLE flag set in their struct exynos_tmu_init_data instances). Please note that this requires moving SoC type assignment and verification from exynos_tmu_probe() to exynos_map_dt_data() so it happens earlier (which is a good thing in itself). There should be no functional changes caused by this patch.
