[PATCH AUTOSEL 4.9 01/18] ARM: dts: rockchip: fix pinctrl sleep nodename for rk3036-kylin and rk3288
From: Johan Jonker jbx6244@gmail.com
[ Upstream commit dfbfb86a43f9a5bbd166d88bca9e07ee4e1bff31 ]
A test with the command below aimed at powerpc generates notifications in the Rockchip ARM tree.
Fix pinctrl "sleep" nodename by renaming it to "suspend" for rk3036-kylin and rk3288
make ARCH=arm dtbs_check DT_SCHEMA_FILES=Documentation/devicetree/bindings/powerpc/sleep.yaml

The pinfunc definitions used GPIO_A as function instead of GPIO_1_0 as done for all the other pins with GPIO functionality. Fix for consistency.
There are no mainline users that needs adaption.

Serial interface uart3 on phyFLEX board is capable of 5-wire connection including signals RTS and CTS for hardware flow control.
Fix signals UART3_CTS_B and UART3_RTS_B padmux assignments and add missing property "uart-has-rtscts" to allow serial interface to be configured and used with the hardware flow control.

[ Upstream commit a979522a1a88556e42a22ce61bccc58e304cb361 ]
To avoid unnecessary recompilations, mkcompile_h does not regenerate compile.h if just the timestamp changed. Though, if KBUILD_BUILD_TIMESTAMP is set, an explicit timestamp for the build was requested, in which case we should not ignore it.
If a user follows the documentation for reproducible builds [1] and defines KBUILD_BUILD_TIMESTAMP as the git commit timestamp, a clean build will have the correct timestamp. A subsequent cherry-pick (or amend) changes the commit timestamp and if an incremental build is done with a different KBUILD_BUILD_TIMESTAMP now, that new value is not taken into consideration. But it should for reproducibility.
Hence, whenever KBUILD_BUILD_TIMESTAMP is explicitly set, do not ignore UTS_VERSION when making a decision about whether the regenerated version of compile.h should be moved into place.

[ Upstream commit 742b0d7e15c333303daad4856de0764f4bc83601 ]
Interrupt line can be configured on different hardware in different way, even inverted. Therefore driver should not enforce specific trigger type - edge falling - but instead rely on Devicetree to configure it.
The Maxim 77686 datasheet describes the interrupt line as active low with a requirement of acknowledge from the CPU therefore the edge falling is not correct.
The interrupt line is shared between PMIC and RTC driver, so using level sensitive interrupt is here especially important to avoid races. With an edge configuration in case if first PMIC signals interrupt followed shortly after by the RTC, the interrupt might not be yet cleared/acked thus the second one would not be noticed.

[ Upstream commit 332a9dd1d86f1e7203fc7f0fd7e82f0b304200fe ]
The shifting of the u8 integer returned fom ahc_inb(ahc, port+3) by 24 bits to the left will be promoted to a 32 bit signed int and then sign-extended to a u64. In the event that the top bit of the u8 is set then all then all the upper 32 bits of the u64 end up as also being set because of the sign-extension. Fix this by casting the u8 values to a u64 before the 24 bit left shift.

Hi,
I always appreciate to have some patches backported, but in this particular case, I wonder what is the rational to backport up to 4.9 some checkpatch warning about log message?
Keeping code aligned to ease other future backport?
I thought that the rule for backport was that it needed to fix a real issue (and sometimes a real 'potential' issue)

The time remaining until expiry of the refresh_timer can be negative. Casting the type to an unsigned 64-bit value will cause integer underflow, making the runtime_refresh_within return false instead of true. These situations are rare, but they do happen.
This does not cause user-facing issues or errors; other than possibly unthrottling cfs_rq's using runtime from the previous period(s), making the CFS bandwidth enforcement less strict in those (special) situations.
