Subject: [PATCH 0/5] Runtime PM support for Exynos I2S driver
Date: Thu, 29 Dec 2016 12:34:02 +0100 [thread overview]
Message-ID: <1483011247-21613-1-git-send-email-m.szyprowski@samsung.com> (raw)
In-Reply-To: CGME20161229113425eucas1p2f95b915a9a66df3e3ff8431b5625b926@eucas1p2.samsung.com
Exynos I2S audio controller was missing proper runtime PM implementation
and this patchset addresses this issue.
This patchset is a another step to add support for audio power domain on
Exynos5 SoCs.
Audio power domain on Exynos5 SoCs contains following hardware modules:
1. clock controller
2. pin controller
3. PL330 DMA controller
4. I2S audio controller
The other patches related to enabling full support for audio power domain
can be found here:
1. PL330 ADMA controller non-irqsafe runtime PM:
https://www.spinics.net/lists/arm-kernel/msg550008.html
2. Runtime PM for clock controllers (Exynos Audio subsystem will be added
in v4 soon): https://www.spinics.net/lists/arm-kernel/msg538122.html
3. Runtime PM support for pin controller:
https://www.spinics.net/lists/linux-samsung-soc/msg56674.html
Patches are based on linux-next from 2016.12.24. Tested on Odroid U3
(Exynos4412), Odroid XU3 (Exynos5422) and TM2 (Exynos5433) boards.
