2018-03-13power: reset: make function sc27xx_poweroff_shutdown staticColin Ian King1-1/+1
The function sc27xx_poweroff_shutdown is local to the source and does not need to be in global scope, so make it static. Cleans up sparse warning: drivers/power/reset/sc27xx-poweroff.c:28:6: warning: symbol 'sc27xx_poweroff_shutdown' was not declared. Should it be static?

2018-03-09power: supply: axp288_fuel_gauge: Fix full status reportingHans de Goede1-12/+35
Commit 2b5a4b4bf222 ("power: supply: axp288_fuel_gauge: Rework get_status()"), switched from 0A current detection to using the capacity register for full detection. It turns out this fixes full reporting on some devices which keep trickle charging long after the capacity register reach 100%, but breaks it on some other devices where the charger stops charging before the capacity register reaches 100%. This commit fixes this by also checking for 0A current when the reported capacity is above 90%.

2018-02-22power: gemini-poweroff: Avoid spurious poweroffLinus Walleij1-13/+17
On the D-Link DIR-685 we get spurious poweroff from infrared. Since that block (CIR) doesn't even have a driver this can be safely ignored, we can revisit this code once we have a device supporting CIR. On the D-Link DNS-313 we get spurious poweroff from the power button. This appears to be an initialization issue: we need to enable the block (start the state machine) before we clear any dangling IRQ. This patch fixes both issues.

This is the mindless scripted replacement of kernel use of POLL* variables as described by Al, done by this script: for V in IN OUT PRI ERR RDNORM RDBAND WRNORM WRBAND HUP RDHUP NVAL MSG; do L=`git grep -l -w POLL$V | grep -v '^t' | grep -v /um/ | grep -v '^sa' | grep -v '/poll.h$'|grep -v '^D'` for f in $L; do sed -i "-es/^\([^\"]*\)\(\<POLL$V\>\)/\\1E\\2/" $f; done done with de-mangling cleanups yet to come. NOTE! On almost all architectures, the EPOLL* constants have the same values as the POLL* constants do. But they keyword here is "almost". For various bad reasons they aren't the same, and epoll() doesn't actually work quite correctly in some cases due to this on Sparc et al. The next patch from Al will sort out the final differences, and we should be all done. Scripted-by: Al Viro <[email protected]> Signed-off-by: Linus Torvalds <[email protected]>

2018-02-10kconfig: remove const qualifier from sym_expand_string_value()Masahiro Yamada3-4/+4
This function returns realloc'ed memory, so the returned pointer must be passed to free() when done. So, 'const' qualifier is odd. It is allowed to modify the expanded string. Signed-off-by: Masahiro Yamada <[email protected]>
2018-02-10kconfig: add xrealloc() helperMasahiro Yamada6-5/+16
We already have xmalloc(), xcalloc(). Add xrealloc() as well to save tedious error handling. Signed-off-by: Masahiro Yamada <[email protected]>
2018-02-09platform/x86: mlx-platform: Add support for new 200G IB and Ethernet systemsVadim Pasternak1-0/+142
It adds support for new Mellanox system types of basic classes qmb7, sn34, sn37, containing systems QMB700 (40x200GbE InfiniBand switch), SN3700 (32x200GbE and 16x400GbE Ethernet switch) and SN3410 (6x400GbE plus 48x50GbE Ethernet switch). These are the Top of the Rack systems, equipped with Mellanox COM-Express carrier board and switch board with Mellanox Quantum device, which supports InfiniBand switching with 40X200G ports and line rate of up to HDR speed or with Mellanox Spectrum-2 device, which supports Ethernet switching with 32X200G ports line rate of up to HDR speed.
