Subject: [PATCH v3 7/7] clk: exynos5433: remove CLK_IGNORE_UNUSED flag from SPI clocks
Date: Tue, 12 Jul 2016 19:02:16 +0900 [thread overview]
Message-ID: <1468317736-18841-8-git-send-email-andi.shyti@samsung.com> (raw)
In-Reply-To: <1468317736-18841-1-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.
