From eb4b0ec75ec34e90bd1594c665f16de0cb4e3bf9 Mon Sep 17 00:00:00 2001 From: Mauro Carvalho Chehab Date: Mon, 16 Nov 2015 08:35:53 -0200 Subject: [media] include/media: move platform_data to linux/platform_data/media Let's not mix platform_data headers with the core headers. Instead, let's create a subdir at linux/platform_data and move the headers to that common place, adding it to MAINTAINERS. The headers were moved with: mkdir include/linux/platform_data/media/; git mv include/media/gpio-ir-recv.h include/media/ir-rx51.h include/media/mmp-camera.h include/media/omap1_camera.h include/media/omap4iss.h include/media/s5p_hdmi.h include/media/si4713.h include/media/sii9234.h include/media/smiapp.h include/media/soc_camera.h include/media/soc_camera_platform.h include/media/timb_radio.h include/media/timb_video.h include/linux/platform_data/media/ And the references fixed with this script: MAIN_DIR="linux/platform_data/" PREV_DIR="media/" DIRS="media/" echo "Checking affected files" >&2 for i in $DIRS; do for j in $(find include/$MAIN_DIR/$i -type f -name '*.h'); do n=`basename $j` git grep -l $n done done|sort|uniq >files && ( echo "Handling files..." >&2; echo "for i in \$(cat files|grep -v Documentation); do cat \$i | \\"; ( cd include/$MAIN_DIR; for j in $DIRS; do for i in $(ls $j); do echo "perl -ne 's,(include [\\\"\\<])$PREV_DIR($i)([\\\"\\>]),\1$MAIN_DIR$j\2\3,; print \$_' |\\"; done; done; echo "cat > a && mv a \$i; done"; ); echo "Handling documentation..." >&2; echo "for i in MAINTAINERS \$(cat files); do cat \$i | \\"; ( cd include/$MAIN_DIR; for j in $DIRS; do for i in $(ls $j); do echo " perl -ne 's,include/$PREV_DIR($i)\b,include/$MAIN_DIR$j\1,; print \$_' |\\"; done; done; echo "cat > a && mv a \$i; done" ); ) >script && . ./script Signed-off-by: Mauro Carvalho Chehab Acked-by: Arnd Bergmann Acked-by: Lee Jones Acked-by: Krzysztof Kozlowski --- include/linux/platform_data/media/gpio-ir-recv.h | 23 ++++++ include/linux/platform_data/media/ir-rx51.h | 10 +++ include/linux/platform_data/media/mmp-camera.h | 9 +++ include/linux/platform_data/media/omap1_camera.h | 35 +++++++++ include/linux/platform_data/media/omap4iss.h | 65 +++++++++++++++++ include/linux/platform_data/media/s5p_hdmi.h | 36 ++++++++++ include/linux/platform_data/media/si4713.h | 48 +++++++++++++ include/linux/platform_data/media/sii9234.h | 24 +++++++ .../platform_data/media/soc_camera_platform.h | 83 ++++++++++++++++++++++ include/linux/platform_data/media/timb_radio.h | 30 ++++++++ include/linux/platform_data/media/timb_video.h | 33 +++++++++ 11 files changed, 396 insertions(+) create mode 100644 include/linux/platform_data/media/gpio-ir-recv.h create mode 100644 include/linux/platform_data/media/ir-rx51.h create mode 100644 include/linux/platform_data/media/mmp-camera.h create mode 100644 include/linux/platform_data/media/omap1_camera.h create mode 100644 include/linux/platform_data/media/omap4iss.h create mode 100644 include/linux/platform_data/media/s5p_hdmi.h create mode 100644 include/linux/platform_data/media/si4713.h create mode 100644 include/linux/platform_data/media/sii9234.h create mode 100644 include/linux/platform_data/media/soc_camera_platform.h create mode 100644 include/linux/platform_data/media/timb_radio.h create mode 100644 include/linux/platform_data/media/timb_video.h (limited to 'include/linux/platform_data') diff --git a/include/linux/platform_data/media/gpio-ir-recv.h b/include/linux/platform_data/media/gpio-ir-recv.h new file mode 100644 index 000000000000..0c298f569d5a --- /dev/null +++ b/include/linux/platform_data/media/gpio-ir-recv.h @@ -0,0 +1,23 @@ +/* Copyright (c) 2012, Code Aurora Forum.

Note that on s3c64xx, the pl08x DMA data is already a pointer, but gets cast to resource_size_t so we can pass it as a resource, and it then gets converted back to a pointer. In contrast, the data we pass for s3c24xx is an index into a device specific table, and we artificially convert that into a pointer for the filter function.

This simplifies the code and makes it more generic by passing the data along with the filter function like we do for other drivers.

I'm keeping this change separate, as there it's less obvious that this is a net win. Upsides of this are: - The ASoC drivers are completely independent from the DMA engine implementation, which simplifies the Kconfig logic and in theory allows the same sound drivers to be built in a kernel that supports different kinds of dmaengine drivers. - Consistency with other subsystems and drivers On the other hand, we have a few downsides: - The s3c24xx-dma driver now needs to be built-in for the ac97 platform device to be instantiated on s3c2440. - samsung_dmaengine_pcm_config cannot be marked 'const' any more because the filter function pointer needs to be set at runtime. This is safe as long we don't have multiple different DMA engines in thet same system at runtime, but is nonetheless ugly.

In theory it could still be used on R-Car Gen1 SoCs, but that requires adding DT support to the driver, which is not planned. Remove the driver, it can be resurrected from git history when needed.

The driver doesn't need to use platform data anymore, hence remove platform data configuration. Make gpio_rcar_priv.has_both_edge_trigger a boolean for consistency with gpio_rcar_info.has_both_edge_trigger. Move gpio_rcar_priv.irq_parent down while we're at it, to prevent gaps on 64-bit.

In theory it could still be used on R-Car Gen1 SoCs, but that would require adding DT support to the driver. Instead, a new driver using the generic PHY framework should be written, as was done for R-Car Gen2. Remove the driver for good.
