Newer Amlogic platforms (Meson 8b and GXBB) use a slightly different register layout for their Infrared Remoete Controller. The decoder mode is now configured in another register. Without the changes to the meson-ir driver we are simply getting incorrect "durations" reported from the hardware (because the hardware is not in time measurement aka software decode mode). This problem was also noticed by some people trying to use this on an ODROID-C1 and ODROID-C2 - the workaround there (probably because the datasheets were not publicy available yet at that time) was to switch to ir_raw_event_store_edge (which leaves it up to the kernel to measure the duration of a pulse). See [0] and [1] for the corresponding patches. Changes in v4: - added support for pinctrl configuration which makes it possible to use the IR decoder when doing a cold-boot. Without these pinctrl changes the IR decoder was only working when booting into stock Android, then rebooting and booting the mainline kernel (with the other patches from this series). Thanks to Kevin Hilman for spotting this issue. - rebased dts changes to Kevin's v4.8/integ branch As discussed on IRC (thanks Neil): Tested-by: Neil Armstrong <narmstrong@xxxxxxxxxxxx> [0] https://github.com/erdoukki/linux-amlogic-1/commit/969b2e2242fb14a13cb651f9a1cf771b599c958b [1] http://forum.odroid.com/viewtopic.php?f=135&t=20504 Martin Blumenstingl (3): pinctrl: amlogic: gxbb: add the IR remote pin ARM64: dts: amlogic: add the pin for the IR remote ARM64: dts: meson-gxbb: Enable the the IR decoder on supported boards Neil Armstrong (3): dt-bindings: media: meson-ir: Add Meson8b and GXBB compatible strings media: rc: meson-ir: Add support for newer versions of the IR decoder ARM64: dts: meson-gxbb: Add Infrared Remote Controller decoder .../devicetree/bindings/media/meson-ir.txt | 5 +++- .../arm64/boot/dts/amlogic/meson-gxbb-odroidc2.dts | 6 +++++ arch/arm64/boot/dts/amlogic/meson-gxbb-p20x.dtsi | 6 +++++ .../boot/dts/amlogic/meson-gxbb-vega-s95.dtsi | 6 +++++ arch/arm64/boot/dts/amlogic/meson-gxbb.dtsi | 14 +++++++++++ drivers/media/rc/meson-ir.c | 29 ++++++++++++++++++---- drivers/pinctrl/meson/pinctrl-meson-gxbb.c | 8 ++++++ 7 files changed, 68 insertions(+), 6 deletions(-) -- 2.9.3 -- To unsubscribe from this list: send the line "unsubscribe devicetree" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
