2019-04-11ARM: dts: imx: Fix the AR803X phy-modeFabio Estevam13-13/+13
Commit 6d4cd041f0af ("net: phy: at803x: disable delay only for RGMII mode") exposed an issue on imx DTS files using AR8031/AR8035 PHYs. The end result is that the boards can no longer obtain an IP address via UDHCP, for example. Quoting Andrew Lunn: "The problem here is, all the DTs were broken since day 0. However, because the PHY driver was also broken, nobody noticed and it worked. Now that the PHY driver has been fixed, all the bugs in the DTs now become an issue" To fix this problem, the phy-mode property needs to be "rgmii-id", which has the following meaning as per Documentation/devicetree/bindings/net/ethernet.txt: "RGMII with internal RX and TX delays provided by the PHY, the MAC should not add the RX or TX delays in this case)" Tested on imx6-sabresd, imx6sx-sdb and imx7d-pico boards with successfully restored networking. Based on the initial submission from Steve Twiss for the imx6qdl-sabresd.

2019-03-20ARM: dts: pfla02: increase phy reset durationMarco Felsch1-0/+1
Increase the reset duration to ensure correct phy functionality. The reset duration is taken from barebox commit 52fdd510de ("ARM: dts: pfla02: use long enough reset for ethernet phy"): Use a longer reset time for ethernet phy Micrel KSZ9031RNX. Otherwise a small percentage of modules have 'transmission timeouts' errors like barebox@Phytec phyFLEX-i.MX6 Quad Carrier-Board:/ ifup eth0 warning: No MAC address set.

2019-03-19ARM: imx6q: cpuidle: fix bug that CPU might not wake up at expected timeKohji Okuno1-17/+10
In the current cpuidle implementation for i.MX6q, the CPU that sets 'WAIT_UNCLOCKED' and the CPU that returns to 'WAIT_CLOCKED' are always the same. While the CPU that sets 'WAIT_UNCLOCKED' is in IDLE state of "WAIT", if the other CPU wakes up and enters IDLE state of "WFI" istead of "WAIT", this CPU can not wake up at expired time. Because, in the case of "WFI", the CPU must be waked up by the local timer interrupt. But, while 'WAIT_UNCLOCKED' is set, the local timer is stopped, when all CPUs execute "wfi" instruction. As a result, the local timer interrupt is not fired. In this situation, this CPU will wake up by IRQ different from local timer. (e.g. broacast timer) So, this fix changes CPU to return to 'WAIT_CLOCKED'.

2019-03-19ARM: dts: imx6dl-yapp4: Use rgmii-id phy mode on the cpu portMichal Vokáč1-1/+1
Use rgmii-id phy mode for the CPU port (MAC0) of the QCA8334 switch to add delays to both Tx and Rx clock. It worked with the rgmii mode before because the qca8k driver (incorrectly) enabled delays in that mode and rgmii-id was not implemented at all. Commit 5ecdd77c61c8 ("net: dsa: qca8k: disable delay for RGMII mode") removed the delays from the RGMII mode and hence broke the networking. To fix the problem, commit a968b5e9d587 ("net: dsa: qca8k: Enable delay for RGMII_ID mode") was introduced. Now the correct phy mode is available so use it.

2019-03-17kbuild: force all architectures except um to include mandatory-yMasahiro Yamada29-47/+18
Currently, every arch/*/include/uapi/asm/Kbuild explicitly includes the common Kbuild.asm file. Factor out the duplicated include directives to scripts/Makefile.asm-generic so that no architecture would opt out of the mandatory-y mechanism. um is not forced to include mandatory-y since it is a very exceptional case which does not support UAPI.

Let's go back to using ";" to be consistent.

2019-03-17kbuild: Make NOSTDINC_FLAGS a simply expanded variableDouglas Anderson1-1/+1
During a simple no-op (nothing changed) build I saw 39 invocations of the C compiler with the argument "-print-file-name=include". We don't need to call the C compiler 39 times for this--one time will suffice. Let's change NOSTDINC_FLAGS to a simply expanded variable to avoid this since there doesn't appear to be any reason it should be recursively expanded. On my build this shaved ~400 ms off my "no-op" build. Note that the recursive expansion seems to date back to the (really old) commit e8f5bdb02ce0 ("[PATCH] Makefile include path ordering"). It's a little unclear to me if the point of that patch was to switch the variable to be recursively expanded (which it did) or to avoid directly assigning to NOSTDINC_FLAGS (AKA to switch to +=) because someone else (out of tree?) was setting it. I presume later since if the only goal was to switch to recursive expansion the patch would have just removed the ":".

* The man page for dpkg-source(1) notes: > -b, --build directory [format-specific-parameters] > Build a source package (--build since dpkg 1.17.14). > <...> > > dpkg-source will build the source package with the first > format found in this ordered list: the format indicated > with the --format command line option, the format > indicated in debian/source/format, “1.0”.

See section > SOURCE PACKAGE FORMATS for an extensive description of > the various source package formats. Thus it would be more foolproof to explicitly use 1.0 (as we always did) than to rely on dpkg-source's defaults. * In a similar vein, debian/rules is not made executable by mkdebian, and dpkg-source warns about that but still silently fixes the file.
