#1472345 — [GIT PULL 0/4] ARM: exynos: Stuff for v4.9

Hi,

Not much stuff for v4.9. No specific order of pulling in.

I expect more patches coming in later so probably I will send
another pull request for v4.9 in a couple of weeks.


BTW, since few weeks and till end of September I am traveling a lot,
so my on-line availability is reduced. After September I will be
leaving Samsung. I hope to continue open-source maintenance during
my personal time.


Best regards,
Krzysztof

Samsung mach/soc update for v4.9:
1. Fix for DMA on S3C24xx. This was probably broken for long time, nobody runs

2. After fixes from Matthew Leach and Ben Dooks, most of our mach code
   and drivers is now endian-safe. Mark the platform as supporting big endian.
3. Cleanups.

Good to know. This reminds me that the s3c24xx DMA code is one of those
that need to be converted to dma_slave_map at some point. Maybe if someone
is now running that code, they could give that a try as well?

It shouldn't be hard to convert, let me know if you need more information.

+Cc Sylwester,

Sylwester recently dig into this platform. I think he managed to play
some audio.

I revived this platform for testing ASoC changes.  I should find time
to do that dma_slave_map refactoring sooner or later.

Or if you would like to do it Sam please go ahead.

Thanks for the suggestion and apologies for the late response. Last couple of 
days I've been figuring out what this would involve and I decided that I want
to give this a try. I found this patch series [1] that I'll use as an example.
If I understand it correctly, I'll need to create a dma_slave_map and
pass that via the platform data into the s3c24xx-dma driver. There I'll
need to fill in the filter_map of the dma slave device. Right?

I pulled this into next/defconfig, but didn't see the conflict,
presumably I'll get it after merging the other branches?

The conflict is between my tree and imx-mxs tree so you might encounter
it later when merging IMX changes.

#1472358 — [GIT PULL 3/4] arm64: dts: exynos: DeviceTree ARM64 for v4.9

Hi,

This is an old one. It was ready for v4.8 but then Marc Zynger posted
some conflicting change so I postponed it. Marc's patch didn't get in,
so there is no reason to wait.

No conflict expected yet, but if you apply Marc's "arm64: dts: Fix
broken architected timer interrupt trigger" then proper resolution would be:

arch/arm64/boot/dts/exynos/exynos7.dtsi:

+                       interrupts = <GIC_PPI 13
+                                       (GIC_CPU_MASK_SIMPLE(8) | IRQ_TYPE_LEVEL_LOW)>,
+                                    <GIC_PPI 14
+                                       (GIC_CPU_MASK_SIMPLE(8) | IRQ_TYPE_LEVEL_LOW)>,
+                                    <GIC_PPI 11
+                                       (GIC_CPU_MASK_SIMPLE(8) | IRQ_TYPE_LEVEL_LOW)>,
+                                    <GIC_PPI 10
+                                       (GIC_CPU_MASK_SIMPLE(8) | IRQ_TYPE_LEVEL_LOW)>;
