watchdog: at91sam9_wdt: Remove now superfluous wdt start and reset

2019-04-26T07:16:32Z

With the new generic function, the scattered other functions are now removed to be replaced by the generic one. The new version also enables the configuration of the watchdog timeout via the DT "timeout-sec" property (if enabled via CONFIG_OF_CONTROL). The watchdog servicing is enabled via CONFIG_WATCHDOG.

arm: at91: Enable watchdog support

2019-04-09T06:28:50Z

This patch enables and starts the watchdog on the AT91 platform if configured. The WD timeout value is read in the AT91 WD device driver from the DT, using the "timeout-sec" DT property. If not provided in the DT, the default value of 2 seconds is used. Signed-off-by: Stefan Roese Cc: Heiko Schocher Cc: Andreas Bießmann Cc: Eugen Hristev

ARM: at91: sama5d2: Wrap cpu detection to fix macb driver

2019-04-09T06:28:50Z

When introducing the SAMA5D27 SoCs, the SAMA5D2 series got an additional chip id. The check if the cpu is sama5d2 was changed from a preprocessor definition (inlining a call to 'get_chip_id()') to a C function, probably to not call get_chip_id twice? That however broke a check in the macb ethernet driver. That driver is more generic and also used for other platforms. I suppose this solution was implemented to use it in 'gem_is_gigabit_capable()', without having to stricly depend on the at91 platform: #ifndef cpu_is_sama5d2 #define cpu_is_sama5d2() 0 #endif That only works as long as cpu_is_sama5d2 is a preprocessor definition. (The same is still true for sama5d4 by the way.) So this is a straight forward fix for the workaround. The not working check on the SAMA5D2 CPU lead to an issue on a custom board with a LAN8720A ethernet phy connected to the SoC: => dhcp ethernet@f8008000: PHY present at 1 ethernet@f8008000: Starting autonegotiation... ethernet@f8008000: Autonegotiation complete ethernet@f8008000: link up, 1000Mbps full-duplex (lpa: 0xffff) BOOTP broadcast 1 BOOTP broadcast 2 BOOTP broadcast 3 BOOTP broadcast 4 BOOTP broadcast 5 BOOTP broadcast 6 BOOTP broadcast 7 BOOTP broadcast 8 BOOTP broadcast 9 BOOTP broadcast 10 BOOTP broadcast 11 BOOTP broadcast 12 BOOTP broadcast 13 BOOTP broadcast 14 BOOTP broadcast 15 BOOTP broadcast 16 BOOTP broadcast 17 Retry time exceeded; starting again Notice the wrong reported link speed, although both SoC and phy only support 100 MBit/s! The real issue on reliably detecting the features of that cadence ethernet mac IP block, is probably more complicated, though.

arm: at91: wdt: Convert watchdog driver to dm/dt

2018-11-16T18:34:34Z

gpio: atmel_pio4: give a full configuration when muxing pins

2018-05-08T13:07:36Z

When a pin is muxed to a peripheral or as a GPIO, the only configuration that can be set is the pullup. It is too restrictive so this patch allows to give a full configuration. Signed-off-by: Ludovic Desroches

SPDX: Convert all of our single license tags to Linux Kernel style

2018-05-07T13:34:12Z

When U-Boot started using SPDX tags we were among the early adopters and there weren't a lot of other examples to borrow from. So we picked the area of the file that usually had a full license text and replaced it with an appropriate SPDX-License-Identifier: entry. Since then, the Linux Kernel has adopted SPDX tags and they place it as the very first line in a file (except where shebangs are used, then it's second line) and with slightly different comment styles than us. In part due to community overlap, in part due to better tag visibility and in part for other minor reasons, switch over to that style. This commit changes all instances where we have a single declared license in the tag as both the before and after are identical in tag contents. There's also a few places where I found we did not have a tag and have introduced one. Signed-off-by: Tom Rini
