Subject: [PATCH v2 7/7] clk: exynos5433: remove CLK_IGNORE_UNUSED flag from SPI clocks
Date: Fri, 08 Jul 2016 23:46:41 +0900
Message-ID: <1467989201-14661-8-git-send-email-andi.shyti@samsung.com> (raw)
In-Reply-To: <1467989201-14661-1-git-send-email-andi.shyti@samsung.com>

Because the Exynos5433 SPI driver supports the ioclk handling and
the following patch:

  http://marc.info/?l=linux-kernel&m=146787645626318&w=2

fixes a synchronus abort issue, none of the SPI clocks require
any critical handling: remove, then, the CLK_IGNORE_UNUSED flag
for the SPI related clocks.
