This is only a cosmetic fix, but at least dmesg output is now getting more readable after all the fixes to remove pointless warnings - Fix gpu_cm node name as we still have a non-standard node name dependency for clocks.

Commit 572cf7d7 ("ARM: dts: Improve omap l4per idling with wlcore edge sensitive interrupt") changed wlcore interrupts to use edge interrupt based on what's specified in the wl1835mod.pdf data sheet. However, there are still cases where we can have lost interrupts as described in omap_gpio_unidle(). And using a level interrupt instead of edge interrupt helps as we avoid the check for untriggered GPIO interrupts in omap_gpio_unidle(). And with commit e6818d29 ("gpio: gpio-omap: configure edge detection for level IRQs for idle wakeup") GPIOs idle just fine with level interrupts. Let's change omap4 and 5 wlcore users back to using level interrupt instead of edge interrupt. Let's not change the others as I've only seen this on omap4 and 5, probably because the other SoCs don't have l4per idle independent of the CPUs.

Merge tag 'omap-for-v5.4/fixes-rc1-signed' of git://git.kernel.org/pub/scm/linux/kernel/git/tmlind/linux-omap into arm/fixes Fixes for omaps for v5.4-rc cycle Here are fixes for omaps to deal with few regressions, and to fix more boot time errors and warnings: - The recent ti-sysc interconnect target module driver changes had incorrect clock bits for both clocks and dts that cause warnings - For omap3-gta04, gpio changes caused the LCD to break a while back, and after discussing things the right fix is to set spi-cs-high - Recent omapdrm changes to use generic panels caused tfp410 to be disabled as we now must enable the generic support for it in defconfig - Recent omapdrm and backlight changes also finally made droid4 LCD to work, so let's enable it in the defconfig it can be used out of the box. This is not strictly a fix, but we still also have the older CONFIG_MFD_TI_LMU options available so this cuts down the confusion for trying to guess which display and which backlight is needed - Recent ti-sysc interconnect target module changes need the gpio module disabled on some boards, but this now needs to happen at the module level, not at the gpio driver level - Recent changes to probe system timers with ti-sysc caused warnings about mismatch in syconfig registers, so let's configure the option for RESET_STATUS as available in the TRMs - Recent changes to probe LCDC with ti-sysc caused warnings about mismatch in sysconfig registers, so let's configure the missing idlemodes for both platform data and dts as documented in TRMs - Since we moved mach-omap2 to probe with device tree, we've been getting voltage controller warnings.

Merge active entropy generation updates. This is admittedly partly "for discussion". We need to have a way forward for the boot time deadlocks where user space ends up waiting for more entropy, but no entropy is forthcoming because the system is entirely idle just waiting for something to happen. While this was triggered by what is arguably a user space bug with GDM/gnome-session asking for secure randomness during early boot, when they didn't even need any such truly secure thing, the issue ends up being that our "getrandom()" interface is prone to that kind of confusion, because people don't think very hard about whether they want to block for sufficient amounts of entropy. The approach here-in is to decide to not just passively wait for entropy to happen, but to start actively collecting it if it is missing. This is not necessarily always possible, but if the architecture has a CPU cycle counter, there is a fair amount of noise in the exact timings of reasonably complex loads. We may end up tweaking the load and the entropy estimates, but this should be at least a reasonable starting point. As part of this, we also revert the revert of the ext4 IO pattern improvement that ended up triggering the reported lack of external entropy. * getrandom() active entropy waiting: Revert "Revert "ext4: make __ext4_get_inode_loc plug"" random: try to actively add entropy rather than passively wait for it

This reverts commit 72dbcf72.

Linus Torvalds authored
For 5.3 we had to revert a nice ext4 IO pattern improvement, because it caused a bootup regression due to lack of entropy at bootup together with arguably broken user space that was asking for secure random numbers when it really didn't need to. See commit 72dbcf72 (Revert "ext4: make __ext4_get_inode_loc plug"). This aims to solve the issue by actively generating entropy noise using the CPU cycle counter when waiting for the random number generator to initialize. This only works when you have a high-frequency time stamp counter available, but that's the case on all modern x86 CPU's, and on most other modern CPU's too. What we do is to generate jitter entropy from the CPU cycle counter under a somewhat complex load: calling the scheduler while also guaranteeing a certain amount of timing noise by also triggering a timer. I'm sure we can tweak this, and that people will want to look at other alternatives, but there's been a number of papers written on jitter entropy, and this should really be fairly conservative by crediting one bit of entropy for every timer-induced jump in the cycle counter. Not because the timer itself would be all that unpredictable, but because the interaction between the timer and the loop is going to be. Even if (and perhaps particularly if) the timer actually happens on another CPU, the cacheline interaction between the loop that reads the cycle counter and the timer itself firing is going to add perturbations to the cycle counter values that get mixed into the entropy pool. As Thomas pointed out, with a modern out-of-order CPU, even quite simple loops show a fair amount of hard-to-predict timing variability even in the absense of external interrupts. But this tries to take that further by actually having a fairly complex interaction. This is not going to solve the entropy issue for architectures that have no CPU cycle counter, but it's not clear how (and if) that is solvable, and the hardware in question is largely starting to be irrelevant. And by doing this we can at least avoid some of the even more contentious approaches (like making the entropy waiting time out in order to avoid the possibly unbounded waiting).

Pull thermal SoC updates from Eduardo Valentin: "This is a really small pull in the midst of a lot of pending patches. We are in the middle of restructuring how we are maintaining the thermal subsystem, as per discussion in our last LPC. For now, I am sending just some changes that were pending in my tree. Looking forward to get a more streamlined process in the next merge window" * 'linus' of git://git.kernel.org/pub/scm/linux/kernel/git/evalenti/linux-soc-thermal: thermal: db8500: Rewrite to be a pure OF sensor thermal: db8500: Use dev helper variable thermal: db8500: Finalize device tree conversion thermal: thermal_mmio: remove some dead code

Pull more i2c updates from Wolfram Sang: - make Lenovo Yoga C630 boot now that the dependencies are merged - restore BlockProcessCall for i801, accidently removed in this merge window - a bugfix for the riic driver - an improvement to the slave-eeprom driver which should have been in the first pull request but sadly got lost in the process * 'i2c/for-next' of git://git.kernel.org/pub/scm/linux/kernel/git/wsa/linux: i2c: slave-eeprom: Add read only mode i2c: i801: Bring back Block Process Call support for certain platforms i2c: riic: Clear NACK in tend isr i2c: qcom-geni: Disable DMA processing on the Lenovo Yoga C630

Pull iommu fixes from Joerg Roedel: "A couple of fixes for the AMD IOMMU driver have piled up: - Some fixes for the reworked IO page-table which caused memory leaks or did not allow to downgrade mappings under some conditions. - Locking fixes to fix a couple of possible races around accessing 'struct protection_domain'. The races got introduced when the dma-ops path became lock-less in the fast-path" * tag 'iommu-fixes-5.4-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/joro/iommu: iommu/amd: Lock code paths traversing protection_domain->dev_list iommu/amd: Lock dev_data in attach/detach code paths iommu/amd: Check for busy devices earlier in attach_device() iommu/amd: Take domain->lock for complete attach/detach path iommu/amd: Remove amd_iommu_devtable_lock iommu/amd: Remove domain->updated iommu/amd: Wait for completion of IOTLB flush in attach_device iommu/amd: Unmap all L7 PTEs when downgrading page-sizes iommu/amd: Introduce first_pte_l7() helper iommu/amd: Fix downgrading default page-sizes in alloc_pte() iommu/amd: Fix pages leak in free_pagetable()
