git://git.kernel.org/pub/scm/linux/kernel/git/clk/linux Pull clk updates from Stephen Boyd: "I'm actually surprised this time. There aren't any new Qualcomm SoC clk drivers. And there's zero diff in the core clk framework. Instead we have new clk drivers for STM and Sophgo, with Samsung^WGoogle in third for the diffstat because they introduced HSI0 and HSI2 clk drivers for Google's GS101 SoC (high speed interface things like PCIe, UFS, and MMC). Beyond those big diffs there's the usual updates to various clk drivers for incorrect parent descriptions or mising MODULE_DEVICE_TABLE()s, etc. Nothing in particular stands out as super interesting here.

2024-02-21reset: Instantiate reset GPIO controller for shared reset-gpiosKrzysztof Kozlowski1-13/+211
Devices sharing a reset GPIO could use the reset framework for coordinated handling of that shared GPIO line. We have several cases of such needs, at least for Devicetree-based platforms. If Devicetree-based device requests a reset line, while "resets" Devicetree property is missing but there is a "reset-gpios" one, instantiate a new "reset-gpio" platform device which will handle such reset line. This allows seamless handling of such shared reset-gpios without need of changing Devicetree binding [1]. To avoid creating multiple "reset-gpio" platform devices, store the Devicetree "reset-gpios" GPIO specifiers used for new devices on a linked list. Later such Devicetree GPIO specifier (phandle to GPIO controller, GPIO number and GPIO flags) is used to check if reset controller for given GPIO was already registered. If two devices have conflicting "reset-gpios" property, e.g. with different ACTIVE_xxx flags, this would allow to spawn two separate "reset-gpio" devices, where the second would fail probing on busy GPIO request.

2023-11-30reset: Fix crash when freeing non-existent optional resetsGeert Uytterhoeven1-4/+4
When obtaining one or more optional resets, non-existent resets are stored as NULL pointers, and all related error and cleanup paths need to take this into account. Currently only reset_control_put() and reset_control_bulk_put() get this right. All of __reset_control_bulk_get(), of_reset_control_array_get(), and reset_control_array_put() lack the proper checking, causing NULL pointer dereferences on failure or release. Fix this by moving the existing check from reset_control_bulk_put() to __reset_control_put_internal(), so it applies to all callers. The double check in reset_control_put() doesn't hurt.

As found with Coccinelle[1], add __counted_by for struct reset_control_array. Additionally, since the element count member must be set before accessing the annotated flexible array member, move its initialization earlier.

git://git.kernel.org/pub/scm/linux/kernel/git/clk/linux Pull clk subsystem updates from Stephen Boyd: "This pull request is full of clk driver changes. In fact, there aren't any changes to the clk framework this time around. That's probably because everyone was on vacation (yours truly included). We did lose a couple clk drivers this time around because nobody was using those devices. That skews the diffstat a bit, but either way, nothing looks out of the ordinary here. The usual suspects are chugging along adding support for more SoCs and fixing bugs. If I had to choose, I'd say the theme for the past few months has been "polish". There's quite a few patches that migrate to devm_platform_ioremap_resource() in here. And there's more than a handful of patches that move the NR_CLKS define from the DT binding header to the driver. There's even patches that migrate drivers to use clk_parent_data and clk_hw to describe clk tree topology.

There are a couple patches to the core clk framework, but they're all basically cleanups or debugging aids. The driver updates and new additions are dominated in the diffstat by Qualcomm and MediaTek drivers. Qualcomm gained a handful of new drivers for various SoCs, and MediaTek gained a bunch of drivers for MT8188. The MediaTek drivers are being modernized as well, so there are updates all over that vendor's clk drivers. There's also a couple other new clk drivers in here, for example the Starfive JH7110 SoC support is added. Outside of the two major SoC vendors though, we have the usual collection of non-critical fixes and cleanups to various clk drivers. It's good to see that we're getting more cleanups and modernization patches. Maybe one day we'll be able to properly split clk providers from clk consumers.

2023-04-13clk: starfive: Avoid casting iomem pointersStephen Boyd1-3/+6
Let's use a wrapper struct for the auxiliary_device made in jh7110_reset_controller_register() so that we can stop casting iomem pointers. The casts trip up tools like sparse, and make for some awkward casts that are largely unnecessary. While we're here, change the allocation from devm and actually free the auxiliary_device memory in the release function. This avoids any use after free problems where the parent device driver is unbound from the device but the auxiliuary_device is still in use accessing devm freed memory.

2023-04-13reset: mpfs: remove MODULE_LICENSE in non-modulesNick Alcock1-1/+0
Since commit 8b41fc4454e ("kbuild: create modules.builtin without Makefile.modbuiltin or tristate.conf"), MODULE_LICENSE declarations are used to identify modules.

We currently use 64bit I/O on the 32bit registers. This works because there are an even number of assert and status registers, so they're only ever accessed in pairs on 64bit boundaries. There are however other reset controllers for audio and video on the JH7100 SoC with only one status register that isn't 64bit aligned so 64bit I/O results in an unaligned access exception. Switch to 32bit I/O in preparation for supporting these resets too.

git://git.kernel.org/pub/scm/linux/kernel/git/clk/linux Pull clk updates from Stephen Boyd: "We have some late breaking reports that a patch series to rework clk rate range support broke boot on some devices, so I've left that branch out of this. Hopefully we can get to that next week, or punt on it and let it bake another cycle. That means we don't really have any changes to the core framework this time around besides a few typo fixes. Instead this is all clk driver updates and fixes. The usual suspects are here (again), with Qualcomm dominating the diffstat. We look to have gained support for quite a few new Qualcomm SoCs and Dmitry worked on updating many of the existing Qualcomm drivers to use clk_parent_data. After that we have MediaTek drivers getting some much needed updates, in particular to support GPU DVFS. There are also quite a few Samsung clk driver patches, but that's mostly because there was a maintainer change and so last release we missed some of those patches. Overall things look normal, but I'm slowly reviewing core framework code nowadays and that shows given the rate range patches had to be yanked last minute. Let's hope this situation changes soon. New Drivers: - Support for Renesas VersaClock7 clock generator family - Add Spreadtrum UMS512 SoC clk support - New clock drivers for MediaTek Helio X10 MT6795 - Display clks for Qualcomm SM6115, SM8450 - GPU clks for Qualcomm SC8280XP - Qualcomm MSM8909 and SM6375 global and SMD RPM clk drivers Deleted Drivers: - Remove DaVinci DM644x and DM646x clk driver support Updates: - Convert Baikal-T1 CCU driver to platform driver - Split reset support out of primary Baikal-T1 CCU driver - Add some missing clks required for RPiVid Video Decoder on RaspberryPi - Mark PLLC critical on bcm2835 - More devm helpers for fixed rate registration - Various PXA168 clk driver fixes - Add resets for MediaTek MT8195 PCIe and USB - Miscellaneous of_node_put() fixes - Nuke dt-bindings/clk path (again) by moving headers to dt-bindings/clock - Convert gpio-clk-gate binding to YAML - Various fixes to AMD/Xilinx Zynqmp clk driver - Graduate AMD/Xilinx "clocking wizard" driver from staging - Add missing DPI1_HDMI clock in MT8195 VDOSYS1 - Clock driver changes to support GPU DVFS on MT8183, MT8192, MT8195 - Fix GPU clock topology on MT8195 - Propogate rate changes from GPU clock gate up the tree - Clock mux notifiers for GPU-related PLLs - Conversion of more "simple" drivers to mtk_clk_simple_probe() - Hook up mtk_clk_simple_remove() for "simple" MT8192 clock drivers - Fixes to previous |struct clk| to |struct clk_hw| conversion on MediaTek - Shrink MT8192 clock driver by deduplicating clock parent lists - Change order between 'sim_enet_root_clk' and 'enet_qos_root_clk' clocks for i.MX8MP - Drop unnecessary newline in i.MX8MM dt-bindings - Add more MU1 and SAI clocks dt-bindings Ids - Introduce slice busy bit check for i.MX93 composite clock - Introduce white list bit check for i.MX93 composite clock - Add new i.MX93 clock gate - Add MU1 and MU2 clocks to i.MX93 clock provider - Add SAI IPG clocks to i.MX93 clock provider - add generic clocks for U(S)ART available on SAMA5D2 SoCs - reset controller support for Polarfire clocks - .round_rate and .set rate support for clk-mpfs - code cleanup for clk-mpfs - PLL support for PolarFire SoC's Clock Conditioning Circuitry - Add watchdog, I2C, pin control/GPIO, and Ethernet clocks on R-Car V4H - Add SDHI, Timer (CMT/TMU), and SPI (MSIOF) clocks on R-Car S4-8 - Add I2C clocks and resets on RZ/V2M - Document clock support for the RZ/Five SoC - mux-variant clock using the table variant to select parents - clock controller for the rv1126 soc - conversion of rk3128 to yaml and relicensing of the yaml bindings to gpl2+MIT (following dt-binding guildelines) - Exynos7885: add FSYS, TREX and MFC clock controllers - Exynos850: add IS and AUD (audio) clock controllers with bindings - ExynosAutov9: add FSYS clock controllers with bindings - ExynosAutov9: correct clock IDs in bindings of Peric 0 and 1 clock controllers, due to duplicated entries.

Merge the new SoC support from Tomer Maimon: "This patchset adds initial support for the Nuvoton Arbel NPCM8XX Board Management controller (BMC) SoC family. The Nuvoton Arbel NPCM8XX SoC is a fourth-generation BMC. The NPCM8XX computing subsystem comprises a quadcore ARM Cortex A35 ARM-V8 architecture. This patchset adds minimal architecture and drivers such as: Clocksource, Clock, Reset, and WD. Some of the Arbel NPCM8XX peripherals are based on Poleg NPCM7XX. This patchset was tested on the Arbel NPCM8XX evaluation board."

Therefore make the driver more generic and add support for lan966x.

After the retirement of MACH_PISTACHIO, the Pistachio Reset Driver is no longer auto-enabled when building a kernel for Pistachio systems. Worse, the driver cannot be enabled by the user at all (unless compile-testing), as the config symbol is invisible. Fix this partially by making the symbol visible again when compiling for MIPS, and dropping the useless default. The user still has to enable the driver manually when building a kernel for Pistachio systems, though.

The reset driver is loaded early via the postcore_initcall interface, and will then be available for the other Sparx5 drivers (SGPIO, SwitchDev etc) that are loaded next, and the first of them to be loaded can perform the one-time Switch Core reset that is needed. The driver has protection so that the system busses, DDR controller, PCI-E and ARM A53 CPU and a few other subsystems are not touched by the reset.

From the Linux kernel point of view these are flavors of the same architecture so there is no need for three top-level arm64 architectures. Simplify this by merging all three architectures into ARCH_INTEL_SOCFPGA and dropping the other ARCH* arm64 Kconfig entries. The side effect is that the INTEL_STRATIX10_SERVICE will now be available for both 32-bit and 64-bit Intel SoCFPGA, even though it is used only for 64-bit.

2021-01-20ARM: remove zte zx platformArnd Bergmann1-1/+1
The ZTE ZX set-top-box SoC platform was added in 2015 by Jun Nie, with Baoyou Xie and Shawn Guo subsequently becoming maintainers after the addition of the 64-bit variant. However, the only machines that were ever supported upstream are the reference designs, not actual set-top-box devices that would benefit from this support. All ZTE set-top-boxes from the past few years seem to be based on third-party SoCs. While there is very little information about zx296702 and zx296718 on the web, I found some references to other chips from the same family, such as zx296716 and zx296719, which were never submitted for upstream support. Finally, there is no support for the GPU on either of them, with the lima and panfrost device drivers having been added after work on the zx platform had stopped. Shawn confirmed that he has not seen any interest in this platform for the past four years, and that it can be removed. Thanks to Jun and Shawn for maintaining this platform over the past five years.
