git://git.kernel.org/pub/scm/linux/kernel/git/arm/arm-soc Pull ARM SoC late DT updates from Arnd Bergmann: "These updates have been kept in a separate branch mostly because they rely on updates to the respective clk drivers to keep the shared header files in sync. - The Renesas r8a7796 (R-Car M3-W) platform gets added, this is an automotive SoC similar to the ⅹ8a7795 chip we already support, but the dts changes rely on a clock driver change that has been merged for v4.9 through the clk tree. - The Amlogic meson-gxbb (S905) platform gains support for a few drivers merged through our tree, in particular the network and usb driver changes are required and included here, and also the clk tree changes. - The Allwinner platforms have seen a large-scale change to their clk drivers and the dts file updates must come after that. This includes the newly added Nextthing GR8 platform, which is derived from sun5i/A13. - Some integrator (arm32) changes rely on clk driver changes. - A single patch for lpc32xx has no such dependency but wasn't added until just before the merge window" * tag 'armsoc-late' of git://git.kernel.org/pub/scm/linux/kernel/git/arm/arm-soc: (99 commits) ARM: dts: lpc32xx: add device node for IRAM on-chip memory ARM: dts: sun8i: Add accelerometer to polaroid-mid2407pxe03 ARM: dts: sun8i: enable UART1 for iNet D978 Rev2 board ARM: dts: sun8i: add pinmux for UART1 at PG dts: sun8i-h3: add I2C0-2 peripherals to H3 SOC dts: sun8i-h3: add pinmux definitions for I2C0-2 dts: sun8i-h3: associate exposed UARTs on Orange Pi Boards dts: sun8i-h3: split off RTS/CTS for UART1 in seperate pinmux dts: sun8i-h3: add pinmux definitions for UART2-3 ARM: dts: sun9i: a80-optimus: Disable EHCI1 ARM: dts: sun9i: cubieboard4: Add AXP806 PMIC device node and regulators ARM: dts: sun9i: a80-optimus: Add AXP806 PMIC device node and regulators ARM: dts: sun9i: cubieboard4: Declare AXP809 SW regulator as unused ARM: dts: sun9i: a80-optimus: Declare AXP809 SW regulator as unused ARM: dts: sun8i: Add touchscreen node for sun8i-a33-ga10h ARM: dts: sun8i: Add touchscreen node for sun8i-a23-polaroid-mid2809pxe04 ARM: dts: sun8i: Add touchscreen node for sun8i-a23-polaroid-mid2407pxe03 ARM: dts: sun8i: Add touchscreen node for sun8i-a23-inet86dz ARM: dts: sun8i: Add touchscreen node for sun8i-a23-gt90h ARM64: dts: meson-gxbb-vega-s95: Enable USB Nodes ...

2016-10-07Merge tag 'armsoc-cleanup' of ↵Linus Torvalds1-41/+5
git://git.kernel.org/pub/scm/linux/kernel/git/arm/arm-soc Pull ARM SoC cleanups from Arnd Bergmann: "The cleanups for v4.9 are a little larger that usual, but thankfully that is almost exclusively due to removing a significant number of files that have become obsolete after the still ongoing conversion of old board files to devicetree. - for mach-omap2, which is still the largest platform in arch/arm/, the conversion to DT is finally complete after the Nokia N900 is now fully supported there, along with the omap3 LDP, and we can remove those two board files. If no regressions are found, another large cleanup for the platform will happen as a follow-up, removing dead code and restructuring the platform based on being DT-only. - In mach-imx, similar work is ongoing, but has not come that far. This time, we remove the obsolete board file for the i.MX1 generation, which like i.MX25, i.MX5, i.MX6, and i.MX7 is now DT-only. The remaining board files are for i.MX2 and i.MX3 machines based on old ARM926 or ARM1136 cores that should work with DT in principle. - realview has just been converted from board files to DT, and a lot of code gets removed in the process. This is the last ARM/Keil/Versatile derived platform that was still using board files, the other ones being integrator, versatile and vexpress. We can probably merge the remaining code into a single directory in the near future. - clps711x had completed the conversion in v4.8, but we accidentally left the files in place that should have been deleted then" * tag 'armsoc-cleanup' of git://git.kernel.org/pub/scm/linux/kernel/git/arm/arm-soc: (21 commits) ARM: select PCI_DOMAINS config from ARCH_MULTIPLATFORM ARM: stop *MIGHT_HAVE_PCI* config from being selected redundantly ARM: imx: (trivial) fix typo and grammar ARM: clps711x: remove extraneous files ARM: imx: use IS_ENABLED() instead of checking for built-in or module ARM: OMAP2+: use IS_ENABLED() instead of checking for built-in or module ARM: OMAP1: use IS_ENABLED() instead of checking for built-in or module ARM: imx: remove platform-mxc_rnga ARM: realview: imply device tree boot ARM: realview: no need to select SMP_ON_UP explicitly ARM: realview: delete the RealView board files ARM: imx: no need to select SMP_ON_UP explicitly ARM: i.MX: Move SOC_IMX1 into 'Device tree only' ARM: i.MX: Remove i.MX1 non-DT support ARM: i.MX: Remove i.MX1 Synertronixx SCB9328 board support ARM: i.MX: Remove i.MX1 Armadeus APF9328 board support ARM: mxs: remove obsolete startup code for TX28 ARM: i.MX31 iomux: remove duplicates with alternate name ARM: i.MX31 iomux: remove plain duplicates ARM: OMAP2+: Drop legacy board file for LDP ...

2016-09-23clk: zx296718: register driver earlier with core_initcallShawn Guo1-1/+5
Clock driver should be registered with an earlier initcall than module_init which is used by most of client device drivers. Otherwise, probing of these client drivers will likely be deferred due to that calls into clk API will return -EPROBE_DEFER. Deferred probing is not a problem for most subsystems, but could bring some side effect for particular subsystem, like display. On ZX296718 platform, we get Linux logo and boot log lost from display device, just because the DRM/KMS driver gets -EPROBE_DEFER from devm_clk_get() call. Let's use core_initcall (qcom and a few other clk drivers use that) for driver registration to avoid those unnecessary -EPROBE_DEFER and get rid of the side effect with ZX296718 display system.

2016-09-22clk: mvebu: dynamically allocate resources in Armada CP110 system controllerMarcin Wojtas1-9/+20
Original commit, which added support for Armada CP110 system controller used global variables for storing all clock information. It worked fine for Armada 7k SoC, with single CP110 block. After dual-CP110 Armada 8k was introduced, the data got overwritten and corrupted.

2016-09-14clk: xgene: Add PMD clockHoan Tran1-0/+221
Add X-Gene PMD clock support. PMD clock is implemented for a single register field. Output rate = parent_rate * (denominator - scale) / denominator with - denominator = bitmask of register field + 1 - scale = values of register field For example, for bitmask is 0x7, denominator will be 8 and scale will be computed and programmed accordingly.

2016-09-14clk-kona-setup: Use kmalloc_array() in parent_process()Markus Elfring1-2/+2
A multiplication for the size determination of a memory allocation indicated that an array data structure should be processed. Thus use the corresponding function "kmalloc_array". This issue was detected by using the Coccinelle software.

2016-09-14clk: meson: fix CLKID_GCLK_VENCI_INT typoArnd Bergmann1-1/+1
The addition of many gate clocks added two entries in an array for the same value: drivers/clk/meson/meson8b.c:479:10: error: initialized field overwritten [-Werror=override-init] [CLKID_GCLK_VENCI_INT] = &meson8b_gclk_venci_int.hw, [CLKID_GCLK_VENCI_INT] = &meson8b_gclk_vencp_int.hw, This was clearly an accident, and since all other identifiers are listed in the order in which they are defined, I'm changing the first one to CLKID_GCLK_VENCI_INT0, making it all consistent again.
