git://git.kernel.org/pub/scm/linux/kernel/git/clk/linux Pull clk updates from Stephen Boyd: "This round of clk driver and framework updates is heavy on the driver update side. The two main highlights in the core framework are the addition of an bulk clk_get API that handles optional clks and an extra debugfs file that tells the developer about the current parent of a clk. The driver updates are dominated by i.MX in the diffstat, but that is mostly because that SoC has started converting to the clk_hw style of clk registration. The next big update is in the Amlogic meson clk driver that gained some support for audio, cpu, and temperature clks while fixing some PLL issues. Finally, the biggest thing that stands out is the conversion of a large part of the Allwinner sunxi-ng driver to the new clk parent scheme that uses less strings and more pointer comparisons to match clk parents and children up. In general, it looks like we have a lot of little fixes and tweaks here and there to clk data along with the normal addition of a handful of new drivers and a couple new core framework features. Core: - Add a 'clk_parent' file in clk debugfs - Add a clk_bulk_get_optional() API (with devm too) New Drivers: - Support gated clk controller on MIPS based BCM63XX SoCs - Support SiLabs Si5341 and Si5340 chips - Support for CPU clks on Raspberry Pi devices - Audsys clock driver for MediaTek MT8516 SoCs Updates: - Convert a large portion of the Allwinner sunxi-ng driver to new clk parent scheme - Small frequency support for SiLabs Si544 chips - Slow clk support for AT91 SAM9X60 SoCs - Remove dead code in various clk drivers (-Wunused) - Support for Marvell 98DX1135 SoCs - Get duty cycle of generic pwm clks - Improvement in mmc phase calculation and cleanup of some rate defintions - Switch i.MX6 and i.MX7 clock drivers to clk_hw based APIs - Add GPIO, SNVS and GIC clocks for i.MX8 drivers - Mark imx6sx/ul/ull/sll MMDC_P1_IPG and imx8mm DRAM_APB as critical clock - Correct imx7ulp nic1_bus_clk and imx8mm audio_pll2_clk clock setting - Add clks for new Exynos5422 Dynamic Memory Controller driver - Clock definition for Exynos4412 Mali - Add CMM (Color Management Module) clocks on Renesas R-Car H3, M3-N, E3, and D3 - Add TPU (Timer Pulse Unit / PWM) clocks on Renesas RZ/G2M - Support for 32 bit clock IDs in TI's sci-clks for J721e SoCs - TI clock probing done from DT by default instead of firmware - Fix Amlogic Meson mpll fractional part and spread sprectrum issues - Add Amlogic meson8 audio clocks - Add Amlogic g12a temperature sensors clocks - Add Amlogic g12a and g12b cpu clocks - Add TPU (Timer Pulse Unit / PWM) clocks on Renesas R-Car H3, M3-W, and M3-N - Add CMM (Color Management Module) clocks on Renesas R-Car M3-W - Add Clock Domain support on Renesas RZ/N1" * tag 'clk-for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/clk/linux: (190 commits) clk: consoldiate the __clk_get_hw() declarations clk: sprd: Add check for return value of sprd_clk_regmap_init() clk: lochnagar: Update DT binding doc to include the primary SPDIF MCLK clk: Add Si5341/Si5340 driver dt-bindings: clock: Add silabs,si5341 clk: clk-si544: Implement small frequency change support clk: add BCM63XX gated clock controller driver devicetree: document the BCM63XX gated clock bindings clk: at91: sckc: use dedicated functions to unregister clock clk: at91: sckc: improve error path for sama5d4 sck registration clk: at91: sckc: remove unnecessary line clk: at91: sckc: improve error path for sam9x5 sck register clk: at91: sckc: add support to free slow clock osclillator clk: at91: sckc: add support to free slow rc oscillator clk: at91: sckc: add support to free slow oscillator clk: rockchip: export HDMIPHY clock on rk3228 clk: rockchip: add watchdog pclk on rk3328 clk: rockchip: add clock id for hdmi_phy special clock on rk3228 clk: rockchip: add clock id for watchdog pclk on rk3328 clk: at91: sckc: add support for SAM9X60 ...

2016-11-01clk: qoriq: Don't allow CPU clocks higher than starting valueScott Wood1-5/+8
The boot-time frequency of a CPU is considered its rated maximum, as we have no other source of such information. However, this was previously only used for chips with 80% restrictions on secondary PLLs. This usually wasn't a problem because most chips/configs boot with a divider of /1, with other dividers being used only for dynamic frequency reduction. However, at least one config (LS1021A at less than 1 GHz) uses a different divider for top speed. This was causing cpufreq to set a frequency beyond the chip's rated speed. This is fixed by applying a 100%-of-initial-speed limit to all CPU PLLs, similar to the existing 80% limit that only applied to some.

Add __init attribute on a function that is only called from other __init functions and that is not inlined, at least with gcc version 4.8.4 on an x86 machine with allyesconfig. Currently, the function is put in the .text.unlikely segment. Declaring it as __init will cause it to be put in the .init.text and to disappear after initialization. The result of objdump -x on the function before the change is as follows: 0000000000000000 l F .text.unlikely 0000000000000071 sysclk_from_fixed.constprop.5 And after the change it is as follows: 0000000000000480 l F .init.text 000000000000006c sysclk_from_fixed.constprop.5 Done with the help of Coccinelle.

2015-10-21clk: qoriq: Move chip-specific knowledge into driverScott Wood1-221/+1040
The device tree should describe the chips (or chip-like subblocks) in the system, but it generally does not describe individual registers -- it should identify, rather than describe, a programming interface. This has not been the case with the QorIQ clockgen nodes. The knowledge of what each bit setting of CLKCnCSR means is encoded in three places (binding, pll node, and mux node), and the last also needs to know which options are valid on a particular chip. All three of these locations are considered stable ABI, making it difficult to fix mistakes (of which I have found several), much less refactor the abstraction to be able to address problems, limitations, or new chips. Under the current binding, a pll clock specifier of 2 means that the PLL is divided by 4 -- and the driver implements this, unless there happen to be four clock-output-names rather than 3, in which case it interprets it as PLL divided by 3. This does not appear in the binding documentation at all. That hack is now considered stable ABI. The current device tree nodes contain errors, such as saying that T1040 can set a core clock to PLL/4 when only PLL and PLL/2 are options. The current binding also ignores some restrictions on clock selection, such as p5020's requirement that if a core uses the "wrong" PLL, that PLL must be clocked lower than the "correct" PLL and be at most 80% of the rated CPU frequency. Possibly because of the lack of the ability to express such nuance in the binding, some valid options are omitted from the device trees, such as the ability on p4080 to run cores 0-3 from PLL3 and cores 4-7 from PLL1 (again, only if they are at most 80% of rated CPU frequency). This omission, combined with excessive caution in the cpufreq driver (addressed in a subsequent patch), means that currently on a 1500 MHz p4080 with typical PLL configuration, cpufreq can lower the frequency to 1200 MHz on half the CPUs and do nothing on the others. With this patchset, all CPUs can be lowered to 1200 MHz on a rev2 p4080, and on a rev3 p4080 half can be lowered to 750 MHz and the other half to 600 MHz. The current binding only deals with CPU clocks. To describe FMan in the device tree, we need to describe its clock. Some chips have additional muxes that work like the CPU muxes, but are not described in the device tree. Others require inspecting the Reset Control Word to determine which PLL is used. Rather than continue to extend this mess, replace it. Have the driver bind to the chip-specific clockgen compatible, and keep the detailed description of quirky chip variations in the driver, where it can be easily fixed, refactored, and extended. Older device trees will continue to work (including a workaround for old ls1021a device trees that are missing compatible and reg in the clockgen node, which even the old binding required). The pll/mux details in old device trees will be ignored, but "clocks" properties pointing at the old nodes will still work, and be directed at the corresponding new clock.
