[PATCH] clk: samsung: exynos5433: use clock_ignore_unused flag for SPI3 related clocks

Show all headers | View raw

From: Jaehoon Chung <jh80.chung@samsung.com>

The SPI 3 bus uses two clocks, a bus clock and an input clock.
Do not disable the clocks when unused in order to allow access to
the SPI 3 device.
