The patch

ASoC: samsung: i2s: Prevent external abort on exynos5433 I2S1 access

has been applied to the asoc tree at

All being well this means that it will be integrated into the linux-next

the next merge window (or sooner if it is a bug fix), however if
problems are discovered then the patch may be dropped or reverted.

You may get further e-mails resulting from automated or manual testing
and review of the tree, please engage with people reporting problems and
send followup patches addressing any issues that are reported if needed.

If any updates are required or you are submitting further changes they

Subject: [PATCH] ASoC: samsung: i2s: Prevent external abort on exynos5433 I2S1

It seems both PCLK_I2S1 and SCLK_I2S1 clocks need to be enabled before
I2S1 control registers can be accessed on exynos5433. If SCLK clock
is disabled an exception is triggered. To fix this parent clock of
the RCLK_SRC clock is assigned to pri_dai->op_clk so required gate
clock is handled by the runtime PM ops.
