2018-05-26ARM: Fix i2c-gpio GPIO descriptor tablesLinus Walleij
I used bad names in my clumsiness when rewriting many board files to use GPIO descriptors instead of platform data. A few had the platform_device ID set to -1 which would indeed give the device name "i2c-gpio". But several had it set to >=0 which gives the names "i2c-gpio.0", "i2c-gpio.1" ... Fix the offending instances in the ARM tree. Sorry for the mess.

I've been queuing them up a bit too long so the list is longer than it otherwise would have been spread out across a few -rcs. In general, it's a scattering of fixes across several platforms, nothing truly serious enough to point out. There's a slightly larger batch of them for the Davinci platforms due to work to bring them back to life after some time, so there's a handful of regressions, some of them going back very far, others more recent. There's also a few patches fixing DT on Renesas platforms since they changed some bindings without remaining backwards compatible, splitting up describing LVDS as a proper bridge instead of having it as part of the display unit.

2018-05-19ARM: replace unnecessary perl with sed and the shell $(( )) operatorRussell King
You can build a kernel in a cross compiling environment that doesn't have perl in the $PATH. Commit 429f7a062e3b broke that for 32 bit ARM. Fix it. As reported by Stephen Rothwell, it appears that the symbols can be either part of the BSS section or absolute symbols depending on the binutils version. When they're an absolute symbol, the $(( )) operator errors out and the build fails. Fix this as well.

2018-05-19ARM: kexec: record parent context registers for non-crash CPUsRussell King
How we got to machine_crash_nonpanic_core() (iow, from an IPI, etc) is not interesting for debugging a crash. The more interesting context is the parent context prior to the IPI being received. Record the parent context register state rather than the register state in machine_crash_nonpanic_core(), which is more relevant to the failing condition.

2018-05-19ARM: kexec: fix kdump register saving on panic()Russell King
When a panic() occurs, the kexec code uses smp_send_stop() to stop the other CPUs, but this results in the CPU register state not being saved, and gdb is unable to inspect the state of other CPUs. Commit 0ee59413c967 ("x86/panic: replace smp_send_stop() with kdump friendly version in panic path") addressed the issue on x86, but ignored other architectures. Address the issue on ARM by splitting out the crash stop implementation to crash_smp_send_stop() and adding the necessary protection. Signed-off-by: Russell King <rmk+kernel@armlinux.org.uk>

2018-05-15KVM: arm/arm64: VGIC/ITS: protect kvm_read_guest() calls with SRCU lockAndre Przywara
kvm_read_guest() will eventually look up in kvm_memslots(), which requires either to hold the kvm->slots_lock or to be inside a kvm->srcu critical section. In contrast to x86 and s390 we don't take the SRCU lock on every guest exit, so we have to do it individually for each kvm_read_guest() call. Provide a wrapper which does that and use that everywhere. Note that ending the SRCU critical section before returning from the kvm_read_guest() wrapper is safe, because the data has been *copied*, so we don't need to rely on valid references to the memslot anymore.

commit b38434145b34 ("ARM: davinci: irqs: Correct McASP1 TX interrupt definition for DM646x") inadvertently removed priority setting for timer0_12 (bottom half of timer0). This timer is used as clockevent. When INTPRIn register setting for an interrupt is left at 0, it is mapped to FIQ by the AINTC causing the timer interrupt to not get generated. Fix it by including an entry for timer0_12 in interrupt priority map array. While at it, move the clockevent comment to the right place.

2018-05-14ARM: keystone: fix platform_domain_notifier array overrunRussell King
platform_domain_notifier contains a variable sized array, which the pm_clk_notify() notifier treats as a NULL terminated array: for (con_id = clknb->con_ids; *con_id; con_id++) pm_clk_add(dev, *con_id); Omitting the initialiser for con_ids means that the array is zero sized, and there is no NULL terminator. This leads to pm_clk_notify() overrunning into what ever structure follows, which may not be NULL.

Then there's a dts fix for missing SoC compatible on ti81xx board dts files that did matter until we added the clkctrl clocks and without that some clocks are now not found. Then there are two logicpd-som-lv specific dts fixes that fix misconfigured pins for WLAN and audio.

https://git.kernel.org/pub/scm/linux/kernel/git/horms/renesas into fixes Renesas ARM Based SoC Fixes for v4.17 Fix LVDS output on Gen2 boards Laurent Pincart says "This patch series fixes LVDS output support on the Lager, Koelsh, Porter and Gose boards that broke in v4.17-rc1 due to the combination of the R-Car DU LVDS driver rework and the DT move of all on-SoC peripherals to a /soc node. We could handle the problem in the R-Car DU LVDS DT backward compatibility code, but that fix would only be used for v4.17 as in v4.18 the Gen2 DT will move to the new LVDS DT bindings. I thus propose merging these three patches in v4.17 already to fix the problem as this is the simplest solution." * tag 'renesas-fixes-for-v4.17' of https://git.kernel.org/pub/scm/linux/kernel/git/horms/renesas: ARM: dts: r8a7793: Convert to new LVDS DT bindings ARM: dts: r8a7791: Convert to new LVDS DT bindings ARM: dts: r8a7790: Convert to new LVDS DT bindings Signed-off-by: Olof Johansson <olof@lixom.net>

Commit 4c9a27a6c66d ("ARM: tegra: Fix ULPI regression on Tegra20") changed "ulpi-link" clock from CDEV2 to PLL_P_OUT4. Turned out that PLL_P_OUT4 is the parent of CDEV2 clock and original clock setup of "ulpi-link" was correct. The reverted patch was fixing USB for one board and broke the other, now Tegra's clk driver correctly sets parent for the CDEV2 clock and hence patch could be reverted safely, restoring USB for all of the boards.

2018-05-03ARM: dts: correct missing "compatible" entry for ti81xx SoCsGraeme Smecher
The missing "compatible" entries are needed by drivers/clk/ti/clkctrl.c, and without them the structures initialized in drivers/clk/ti/clk-814x.c are not passed to configuration code. The result is a "not found from clkctrl data" error message, although boot proceeds anyway. The reason why the compatible is not found is because the board specific files override the SoC compatible without including it. This did not cause any issues until with the clkctrl nodes got introduced. Very lightly tested on a (lurching) AM3874 design that's in the middle of a kernel upgrade from TI's abandoned 2.6.37 tree. Also tested on j5eco-evm and hp-t410 to verify the clkctrl clocks are found.

2018-05-03ARM: OMAP1: ams-delta: fix deferred_fiq handlerJanusz Krzysztofik
The deferred_fiq handler used to limit hardware operations to IRQ unmask only, relying on gpio-omap assigned handler performing the ACKs. Since commit 80ac93c27441 ("gpio: omap: Fix lost edge interrupts") this is no longer the case as handle_edge_irq() has been replaced with handle_simmple_irq() which doesn't touch the hardware. Add single ACK operation per each active IRQ pin to the handler. While being at it, move unmask operation out of irq_counter loop so it is also called only once for each active IRQ pin.
