2020-12-17arm64: Work around broken GCC 4.9 handling of "S" constraintMarc Zyngier
GCC 4.9 seems to have a problem with the "S" asm constraint when the symbol lives in the same compilation unit, and pretends the constraint is impossible: $ cat x.c void *foo(void) { static int x; int *addr; asm("adrp %0, %1" : "=r" (addr) : "S" (&x)); return addr; } $ ~/Work/gcc-linaro-aarch64-linux-gnu-4.9-2014.09_linux/bin/aarch64-linux-gnu-gcc -S -x c -O2 x.c x.c: In function ‘foo’: x.c:5:2: error: impossible constraint in ‘asm’ asm("adrp %0, %1" : "=r" (addr) : "S" (&x)); ^ Boo. Following revisions of the compiler work just fine, though. We can fallback to the "i" constraint for GCC version prior to 5.0, which *seems* to do the right thing. Hopefully we will be able to remove this at some point, but in the meantime this gets us going.

2020-12-17clk: axi-clkgen: move the OF table at the bottom of the fileAlexandru Ardelean
The change is mostly cosmetic. No functional changes. Since the driver now uses of_device_get_match_data() to obtain some driver specific info, there is no need to define the OF table before the probe function.

2020-12-17clk: axi-clkgen: wrap limits in a struct and keep copy on the state objectAlexandru Ardelean
Up until the these limits were global/hard-coded, since they are typically limits of the fabric. However, since this is an FPGA generated clock, this may run on setups where one clock is on a fabric, and another one synthesized on another fabric connected via PCIe (or some other inter-connect, and then these limits need to be adjusted for each instance of the AXI CLKGEN. This change wraps the current constants in 'axi_clkgen_limits' struct and the 'axi_clkgen' instance keeps a copy of these limits, which is initialized at probe from the default limits. The limits are stored on the device-tree OF table, so that we can adjust them via the compatible string.

2020-12-17clk: ti: omap5: Fix reboot DPLL lock failure when using ABE TIMERsDavid Shah
Having the ABE DPLL ref and bypass muxes set to different inputs was causing the DPLL not to lock when TIMER8 was used, as it is in the Pyra for the backlight. This patch fixes this by setting abe_dpll_bypass_clk_mux to sys_32k_ck in omap5xxx_dt_clk_init. A similar patch may also be needed for OMAP44xx which has similar code in omap4xxx_dt_clk_init, but I have not added this as I have no hardware to test on.

2020-12-17clk: Add hardware-enable column to clk summaryDmitry Osipenko
Add "hardware enable" column to the clk summary in order to show actual hardware enable-state of all clocks. The possible states are "Y/N/?", where question mark means that state is unknown, i.e. clock isn't a mux and clk-driver doesn't support is_enabled() callback for this clock. In conjunction with clk_ignore_unused, this tells us what unused clocks are left enabled after bootloader. This is also a useful aid for debugging interactions with firmware which changes clock states without notifying kernel.

git://git.kernel.org/pub/scm/linux/kernel/git/soc/soc Pull ARM device tree updates from Arnd Bergmann: "Across all platforms, there is a continued move towards DT schema for validating the dts files. As a result there are bug fixes for mistakes that are found using these schema, in addition to warnings from the dtc compiler. As usual, many changes are for adding support for additional on-chip and on-board components in the machines we already support. The newly supported SoCs for this release are: - MStar Infinity2M, a low-end IP camera chip based on a dual-core Cortex-A7, otherwise similar to the Infinity chip we already support. This is also known as the SigmaStar SSD202D, and we add support for the Honestar ssd201htv2 development kit. - Nuvoton NPCM730, a Cortex-A9 based Baseboard Management Controller (BMC), in the same family as the NPCM750. This gets used in the Ampere Altra based "Fii Kudo" server and the Quanta GSJ, both of which are added as well. - Broadcom BCM4908, a 64-bit home router chip based on Broadcom's own Brahma-B53 CPU. Support is also added for the Asus ROG Rapture GT-AC5300 high-end WiFi router based on this chip. - Mediatek MT8192 is a new SoC based on eight Cortex-A76/A55 cores, meant for faster Chromebooks and tablets. It gets added along with its reference design. - Mediatek MT6779 (Helio P90) is a high-end phone chip from last year's generation, also added along with its reference board. This one is still based on Cortex-A75/A55. - Mediatek MT8167 is a version of the already supported MT8516 chip, both based on Cortex-A35. It gets added along with the "Pumpkin" single board computer, but is likely to also make its way into low-end tablets in the future. For the already supported chips, there are a number of new boards. Interestingly there are more 32-bit machines added this time than 64-bit. Here is a brief list of the new boards: - Three new Mikrotik router variants based on Marvell Prestera 98DX3236, a close relative of the more common Armada XP - A reference board for the Marvell Armada 382 - Three new servers using ASpeed baseboard management controllers, the actual machines being from Bytedance, Facebook and IBM, and one machine using the Nuvoton NPCM750 BMC. - The Galaxy Note 10.1 (P4) tablet, using an Exynos 4412. - The usual set of 32-bit i.MX industrial/embedded hardware: * Protonic WD3 (tractor e-cockpit) * Kamstrup OMNIA Flex Concentrator (smart grid platform) * Van der Laan LANMCU (food storage) * Altesco I6P (vehicle inspection stations) * PHYTEC phyBOARD-Segin/phyCORE-i.MX6UL baseboard - DH electronics STM32MP157C DHCOM, a PicoITX carrier board for the aleady supported DHCOM module - Three new Allwinner SoC based single-board computers: * NanoPi R1 (H3 based) * FriendlyArm ZeroPi (H3 based) * Elimo Initium SBC (S3 based) - Ouya Game Console based on Nvidia Tegra 3 - Version 5 of the already supported Zynq Z-Turn MYIR Board - LX2162AQDS, a reference platform for NXP Layerscape LX2162A, which is a repackaged 16-core LX2160A - A series of Kontron i.MX8M Mini baseboard/SoM versions - Espressobin Ultra, a new variant of the popular Armada 3700 based board, - IEI Puzzle-M801, a rackmount network appliance based on Marvell Armada 8040 - Microsoft Lumia 950 XL, a phone - HDK855 and HDK865 Hardware development kits for Qualcomm sm8250 and sm8150, respectively - Three new board variants of the "Trogdor" Chromebook (sc7180) - New board variants of the Renesas based "Kingfisher" and "HiHope" reference boards - Kobol Helios64, an open source NAS appliance based on Rockchips RK3399 - Engicam PX30.Core, a SoM based on Rockchip PX30, along with a few carrier boards" * tag 'arm-soc-dt-5.11' of git://git.kernel.org/pub/scm/linux/kernel/git/soc/soc: (679 commits) arm64: dts: sparx5: Add SGPIO devices arm64: dts: sparx5: Add reset support dt-bindings: gpio: Add a binding header for the MSC313 GPIO driver ARM: mstar: SMP support ARM: mstar: Wire up smpctrl for SSD201/SSD202D ARM: mstar: Add smp ctrl registers to infinity2m dtsi ARM: mstar: Add dts for Honestar ssd201htv2 ARM: mstar: Add chip level dtsi for SSD202D ARM: mstar: Add common dtsi for SSD201/SSD202D ARM: mstar: Add infinity2m support dt-bindings: mstar: Add Honestar SSD201_HT_V2 to mstar boards dt-bindings: vendor-prefixes: Add honestar vendor prefix dt-bindings: mstar: Add binding details for mstar,smpctrl ARM: mstar: Fill in GPIO controller properties for infinity ARM: mstar: Add gpio controller to MStar base dtsi ARM: zynq: Fix incorrect reference to XM013 instead of XM011 ARM: zynq: Convert at25 binding to new description on zc770-xm013 ARM: zynq: Fix OCM mapping to be aligned with binding on zc702 ARM: zynq: Fix leds subnode name for zc702/zybo-z7 ARM: zynq: Rename bus to be align with simple-bus yaml ...

2020-12-16devlink: use _BITUL() macro instead of BIT() in the UAPI headerTobias Klauser
The BIT() macro is not available for the UAPI headers. Moreover, it can be defined differently in user space headers. Thus, replace its usage with the _BITUL() macro which is already used in other macro definitions in <linux/devlink.h>.

Drivers, drivers and drivers. Not a single core change. Some new stuff, especially a bunch of new Intel, Qualcomm and Ocelot SoCs. As part of the modularization attempt, I applied one patch affecting the firmware subsystem as a functional (not syntactic/semantic) dependency and then it blew up in our face, so I had to revert it, bummer. It will come in later, through that subsystem, I guess. New drivers: - New driver for the Microchip Serial GPIO "SGPIO". - Qualcomm SM8250 LPASS (Low Power Audio Subsystem) GPIO driver.

We need the bits of _TIF_WORK_MASK to be contiguous in order to to use this as an immediate argument to an AND instruction in entry.S. We happened to change these bits in commits: b5a5a01d8e9a ("arm64: uaccess: remove addr_limit_user_check()") 192caabd4dd9 ("arm64: add support for TIF_NOTIFY_SIGNAL") which each worked in isolation, but the merge resolution in commit: 005b2a9dc819 ("Merge tag 'tif-task_work.arch-2020-12-14' of git://git.kernel.dk/linux-block") happened to make the bits non-contiguous. Fix this by moving TIF_NOTIFY_SIGNAL to be bit 6, which is contiguous with the rest of _TIF_WORK_MASK. Otherwise, we'll get a build-time failure as below: arch/arm64/kernel/entry.S: Assembler messages: arch/arm64/kernel/entry.S:733: Error: immediate out of range at operand 3 -- `and x2,x19,#((1<<1)|(1<<0)|(1<<2)|(1<<3)|(1<<4)|(1<<5)|(1<<7))' scripts/Makefile.build:360: recipe for target 'arch/arm64/kernel/entry.o' failed Fixes: 005b2a9dc819a126 ("Merge tag 'tif-task_work.arch-2020-12-14' of git://git.kernel.dk/linux-block") Signed-off-by: Mark Rutland <mark.rutland@arm.com> Cc: Catalin Marinas <catalin.marinas@arm.com> Cc: Will Deacon <will@kernel.org> Signed-off-by: Linus Torvalds <torvalds@linux-foundation.org>
