Everyone: These two patches are first results of an effort to port RAVE SP (Supervisory Processor) MFD and it's children drivers from Linux kernel to Barebox. Patch 1/2 brings MFD driver with its core API and patch 2/2 adds support for watchdog "cell" of the RAVE SP device. With a very few exceptions, the code of the drivers is identical to the code of their Linux counterparts. These drivers are also first users of "serdev" API work that was recently merged and should server as a reasonable example of its usage. Feedback is wellcome! Changes since [v1]: - rave_sp_wdt_set_timeout fixed to correctly handle timeout of zero (as pointed out by Sascha) Thanks, Andrey Smirnov [v1] http://lists.infradead.org/pipermail/barebox/2018-April/032725.html Andrey Smirnov (2): watchdog: Port RAVE SP watchdog driver from Linux kernel mfd: rave-sp: Add temporary workaround for missing GET_STATUS drivers/mfd/rave-sp.c | 18 +- drivers/watchdog/Kconfig | 5 + drivers/watchdog/Makefile | 1 + drivers/watchdog/rave-sp-wdt.c | 426 +++++++++++++++++++++++++++++++++++++++++ 4 files changed, 448 insertions(+), 2 deletions(-) create mode 100644 drivers/watchdog/rave-sp-wdt.c -- 2.14.3 _______________________________________________ barebox mailing list barebox@xxxxxxxxxxxxxxxxxxx http://lists.infradead.org/mailman/listinfo/barebox
