2017-12-26dt-bindings: Use lower case hex in unit-addressesRob Herring
DT unit addresses should be lower case hex. Fix all the binding examples. Converted with the following command from Krzysztof Kozlowski: sed -e 's/@\([a-fA-F0-9_-]*\) {/@\L\1 {/' -i $(find Documentation/devicetree/bindings -name '*.txt') Signed-off-by: Rob Herring <robh@kernel.org>
2017-02-24watchdog: s3c2410: Fix infinite interrupt in soft modeKrzysztof Kozlowski
In soft (no-reboot) mode, the driver self-pings watchdog upon expiration of an interrupt. However the interrupt itself was not cleared thus on first hit, the system enters infinite interrupt handling loop. On Odroid U3 (Exynos4412), when booted with s3c2410_wdt.soft_noboot=1 argument the console is flooded: # killall -9 watchdog [ 60.523760] s3c2410-wdt 10060000.watchdog: watchdog timer expired (irq) [ 60.536744] s3c2410-wdt 10060000.watchdog: watchdog timer expired (irq) Fix this by writing something to the WTCLRINT register to clear the interrupt. The register WTCLRINT however appeared in S3C6410 so a new watchdog quirk and flavor are needed.
