git://git.kernel.org/pub/scm/linux/kernel/git/shawnguo/linux into fixes i.MX fixes for 5.1, round 2: - A couple of imx6q-logicpd device tree fixes to reduce inrush current, so that the board can always work properly. - Fix buggy device trees that use AR803X to set up phy-mode as rgmii-id. These device trees are broken since day one, and the bug gets exposed by the AR803X phy driver changes. i.MX community agreed to fix those broken device trees rather than supporting messy back compatibility in driver code. * tag 'imx-fixes-5.1-2' of git://git.kernel.org/pub/scm/linux/kernel/git/shawnguo/linux: ARM: dts: imx6q-logicpd: Reduce inrush current on USBH1 ARM: dts: imx6q-logicpd: Reduce inrush current on start ARM: dts: imx: Fix the AR803X phy-mode Signed-off-by: Olof Johansson <olof@lixom.net>
2019-04-21ARM: dts: ls1021: Fix SGMII PCS link remaining down after PHY disconnectVladimir Oltean2-2/+18
Each eTSEC MAC has its own TBI (SGMII) PCS and private MDIO bus. But due to a DTS oversight, both SGMII-compatible MACs of the LS1021 SoC are pointing towards the same internal PCS. Therefore nobody is controlling the internal PCS of eTSEC0. Upon initial ndo_open, the SGMII link is ok by virtue of U-boot initialization. But upon an ifdown/ifup sequence, the code path from ndo_open -> init_phy -> gfar_configure_serdes does not get executed for the PCS of eTSEC0 (and is executed twice for MAC eTSEC1). So the SGMII link remains down for eTSEC0. On the LS1021A-TWR board, to signal this failure condition, the PHY driver keeps printing '803x_aneg_done: SGMII link is not ok'. Also, it changes compatible of mdio0 to "fsl,etsec2-mdio" to match mdio1 device.

2019-04-11ARM: dts: imx6q-logicpd: Reduce inrush current on USBH1Adam Ford1-0/+1
Some USB peripherals draw more power, and the sourcing regulator take a little time to turn on. This patch fixes an issue where some devices occasionally do not get detected, because the power isn't quite ready when communication starts, so we add a bit of a delay.

2019-04-11ARM: dts: imx6q-logicpd: Reduce inrush current on startAdam Ford1-0/+1
The main 3.3V regulator sources a series of additional regulators. This patch adds a small delay, so when the 3.3V regulator comes on it delays a bit before the subsequent regulators can come on. This reduces the inrush current a bit on the external DC power supply to help prevent a situation where the sourcing power supply cannot source enough current and overloads and the kit fails to start.

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.

2019-04-05syscalls: Remove start and number from syscall_set_arguments() argsSteven Rostedt (VMware)1-18/+4

Note, as of today, there are no users of syscall_set_arguments(). But we are told that there will be soon. But for now, at least make it consistent with syscall_get_arguments().

2019-04-05syscalls: Remove start and number from syscall_get_arguments() argsSteven Rostedt (Red Hat)1-20/+3
At Linux Plumbers, Andy Lutomirski approached me and pointed out that the function call syscall_get_arguments() implemented in x86 was horribly written and not optimized for the standard case of passing in 0 and 6 for the starting index and the number of system calls to get. When looking at all the users of this function, I discovered that all instances pass in only 0 and 6 for these arguments. Instead of having this function handle different cases that are never used, simply rewrite it to return the first 6 arguments of a system call. This should help out the performance of tracing system calls by ptrace, ftrace and perf.

I do not see any consistency about headers_install of <linux/kvm_para.h> and <asm/kvm_para.h>. According to my analysis of Linux 5.1-rc1, there are 3 groups: [1] Both <linux/kvm_para.h> and <asm/kvm_para.h> are exported alpha, arm, hexagon, mips, powerpc, s390, sparc, x86 [2] <asm/kvm_para.h> is exported, but <linux/kvm_para.h> is not arc, arm64, c6x, h8300, ia64, m68k, microblaze, nios2, openrisc, parisc, sh, unicore32, xtensa [3] Neither <linux/kvm_para.h> nor <asm/kvm_para.h> is exported csky, nds32, riscv This does not match to the actual KVM support. At least, [2] is half-baked. Nor do arch maintainers look like they care about this. For example, commit 0add53713b1c ("microblaze: Add missing kvm_para.h to Kbuild") exported <asm/kvm_para.h> to user-space in order to fix an in-kernel build error. We have two ways to make this consistent: [A] export both <linux/kvm_para.h> and <asm/kvm_para.h> for all architectures, irrespective of the KVM support [B] Match the header export of <linux/kvm_para.h> and <asm/kvm_para.h> to the KVM support My first attempt was [A] because the code looks cleaner, but Paolo suggested [B]. So, this commit goes with [B]. For most architectures, <asm/kvm_para.h> was moved to the kernel-space. I changed include/uapi/linux/Kbuild so that it checks generated asm/kvm_para.h as well as check-in ones. After this commit, there will be two groups: [1] Both <linux/kvm_para.h> and <asm/kvm_para.h> are exported arm, arm64, mips, powerpc, s390, x86 [2] Neither <linux/kvm_para.h> nor <asm/kvm_para.h> is exported alpha, arc, c6x, csky, h8300, hexagon, ia64, m68k, microblaze, nds32, nios2, openrisc, parisc, riscv, sh, sparc, unicore32, xtensa Signed-off-by: Masahiro Yamada <yamada.masahiro@socionext.com> Acked-by: Cornelia Huck <cohuck@redhat.com> Signed-off-by: Paolo Bonzini <pbonzini@redhat.com>

The SPI DT bindings are for historical reasons a pitfall, the ability to flag a GPIO line as active high/low with the second cell flags was introduced later so the SPI subsystem will only accept the bool flag spi-cs-high to indicate that the line is active high. It worked by mistake, but the mistake was corrected in another commit. The comment in the DTS file was also misleading: this CS is indeed active high.

2019-03-20KVM: arm/arm64: Fix handling of stage2 huge mappingsSuzuki K Poulose1-0/+2
We rely on the mmu_notifier call backs to handle the split/merge of huge pages and thus we are guaranteed that, while creating a block mapping, either the entire block is unmapped at stage2 or it is missing permission. However, we miss a case where the block mapping is split for dirty logging case and then could later be made block mapping, if we cancel the dirty logging. This not only creates inconsistent TLB entries for the pages in the the block, but also leakes the table pages for PMD level. Handle this corner case for the huge mappings at stage2 by unmapping the non-huge mapping for the block. This could potentially release the upper level table. So we need to restart the table walk once we unmap the range.

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'.

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.

2019-03-18ARM: dts: rockchip: Fix SD card detection on rk3288-tinkerDavid Summers1-1/+2
The Problem: On ASUS Tinker Board S, when booting from the eMMC, and there is card in the sd slot, there are constant errors. Also when warm reboot, uboot can not access the sd slot Cause: Identified by Robin Murphy @ ARM. The Card Detect on rk3288 devices is pulled up by vccio-sd; so when the regulator powers this off, card detect gives spurious errors. A second problem, is during power down, vccio-sd apprears to be powered down. This causes a problem when warm rebooting from the sd card. This was identified by Jonas Karlman. History: A common fault on these rk3288 board, which impliment the reference design. When this arose before: http://lists.infradead.org/pipermail/linux-arm-kernel/2014-August/281153.html And Ulf and Jaehoon clearly said this was a broken card detect design, which should be solved via polling Solution: Hence broken-cd is set as a property. This cures the errors. The powering down of vccio-sd during reboot is cured by adding regulator-boot-on. This solutions has been fairly widely reviewed and tested.
