2021-07-31clk: fix leak on devm_clk_bulk_get_all() unwindBrian Norris1-1/+8
clk_bulk_get_all() allocates an array of struct clk_bulk data for us (unlike clk_bulk_get()), so we need to free it. Let's use the clk_bulk_put_all() helper. kmemleak complains, on an RK3399 Gru/Kevin system: unreferenced object 0xffffff80045def00 (size 128): comm "swapper/0", pid 1, jiffies 4294667682 (age 86.394s) hex dump (first 32 bytes): 44 32 60 fe fe ff ff ff 00 00 00 00 00 00 00 00 D2`............. 48 32 60 fe fe ff ff ff 00 00 00 00 00 00 00 00 H2`............. backtrace: [<00000000742860d6>] __kmalloc+0x22c/0x39c [<00000000b0493f2c>] clk_bulk_get_all+0x64/0x188 [<00000000325f5900>] devm_clk_bulk_get_all+0x58/0xa8 [<00000000175b9bc5>] dwc3_probe+0x8ac/0xb5c [<000000009169e2f9>] platform_drv_probe+0x9c/0xbc [<000000005c51e2ee>] really_probe+0x13c/0x378 [<00000000c47b1f24>] driver_probe_device+0x84/0xc0 [<00000000f870fcfb>] __device_attach_driver+0x94/0xb0 [<000000004d1b92ae>] bus_for_each_drv+0x8c/0xd8 [<00000000481d60c3>] __device_attach+0xc4/0x150 [<00000000a163bd36>] device_initial_probe+0x1c/0x28 [<00000000accb6bad>] bus_probe_device+0x3c/0x9c [<000000001a199f89>] device_add+0x218/0x3cc [<000000001bd84952>] of_device_add+0x40/0x50 [<000000009c658c29>] of_platform_device_create_pdata+0xac/0x100 [<0000000021c69ba4>] of_platform_bus_create+0x190/0x224 Fixes: f08c2e2865f6 ("clk: add managed version of clk_bulk_get_all") Cc: Dong Aisheng <aisheng.dong@nxp.com> Cc: stable@vger.kernel.org Signed-off-by: Brian Norris <briannorris@chromium.org> Link: https://lore.kernel.org/r/20210731025950.2238582-1-briannorris@chromium.org Signed-off-by: Stephen Boyd <sboyd@kernel.org>

Commit a0384ecfe2aa ("clk: qcom: smd-rpm: De-duplicate identical entries") introduces the following regression on MSM8936/MSM8939, as RPM_SMD_PCNOC_A_CLK gets pointed to pcnoc_clk by mistake.

This reverts commit db400ac1444b756030249ed4a35e53a68e557b59. We have drivers that are still using the .round_rate ops from here. We could implement both determine_rate and round_rate for these divider ops, but for now let's just kick out the commit that tried to change it and convert various drivers properly.

git://git.kernel.org/pub/scm/linux/kernel/git/clk/linux Pull clk updates from Stephen Boyd: "This round has a diffstat dominated by Qualcomm clk drivers. Honestly though that's just a bunch of data so the diffstat reflects that. Looking beyond that there's just a bunch of updates all around in various clk drivers. Renesas and NXP (for i.MX) are two SoC vendors that have a lot of patches in here. Overall the driver changes look to be mostly enabling more clks and non-critical fixes that we could hold until the next merge window. I'm especially excited about the series from Arnd that graduates clkdev to be the only implementation of clk_get() and clk_put(). That's a good step in the right direction to migreate eveerything over to the common clk framework. Now we don't have to worry about clkdev specific details, they're just part of the clk API now. Core: - clkdev is now the only option, i.e. clk_get()/clk_put() is implemented in only one place in the kernel instead of in drivers/clk/clkdev.c and in architectures that want their own implementation New Drivers: - Texas Instruments' LMK04832 Ultra Low-Noise JESD204B Compliant Clock Jitter Cleaner With Dual Loop PLLs - Qualcomm MDM9607 GCC - Qualcomm SC8180X display clks - Qualcomm SM6125 GCC - Qualcomm SM8250 CAMCC (camera) - Renesas RZ/G2L SoC - Hisilicon hi3559A SoC Updates: - Stop using clock-output-names in ST clk drivers (yay!) - Support secure mode of STM32MP1 SoCs - Improve clock support for Actions S500 SoC - duty cycle setting support on qcom clks - Add TI am33xx spread spectrum clock support - Use determine_rate() for the Amlogic pll ops instead of round_rate() - Restrict Amlogic gp0/1 and audio plls range on g12a/sm1 - Improve Amlogic axg-audio controller error on deferral - Add NNA clocks on Amlogic g12a - Reduce memory footprint of Rockchip PLL rate tables - A fix for the newly added Rockchip rk3568 clk driver - Exported clock for the newly added Rockchip video decoder - Remove audio ipg clock from i.MX8MP - Remove deprecated legacy clock binding for i.MX SCU clock driver - Use common clk-imx8qxp for both i.MX8QXP and i.MX8QM - Add multiple clocks to clk-imx8qxp driver (enet, hdmi, lcdif, audio, parallel interface) - Add dedicated clock ops for i.MX paralel interface - Different fixes for clocks controlled by ATF on i.MX SoCs - Add A53/A72 frequency scaling support i.MX clk-scu driver - Add special case for DCSS clock on suspend for i.MX clk-scu driver - Add parent save/restore on suspend/resume to i.MX clk-scu driver - Skip runtime PM enablement for CPU clocks in i.MX clk-scu driver - Remove the sys1_pll/sys2_pll clock gates for i.MX8MQ and their bindings - Tegra clk driver no longer deasserts resets on clk_enable as it gets in the way of certain power-up sequences - Fix compile testing for Tegra clk driver - One patch to fix a divider on the Allwinner v3s Audio PLL - Add support for CPU core clock boost modes on Renesas R-Car Gen3 - Add ISPCS (Image Signal Processor) clocks on Renesas R-Car V3U - Switch SH/R-Mobile and R-Car "DIV6" clocks to .determine_rate() and improve support for multiple parents - Switch Renesas RZ/N1 divider clocks to .determine_rate() - Add ZA2 (Audio Clock Generator) clock on Renesas R-Car D3 - Convert ar7 to common clk framework - Convert ralink to common clk framework" * tag 'clk-for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/clk/linux: (161 commits) clk: zynqmp: Handle divider specific read only flag clk: zynqmp: Use firmware specific mux clock flags clk: zynqmp: Use firmware specific divider clock flags clk: zynqmp: Use firmware specific common clock flags clk: lmk04832: Use of match table clk: lmk04832: Depend on SPI clk: stm32mp1: new compatible for secure RCC support dt-bindings: clock: stm32mp1 new compatible for secure rcc dt-bindings: reset: add MCU HOLD BOOT ID for SCMI reset domains on stm32mp15 dt-bindings: reset: add IDs for SCMI reset domains on stm32mp15 dt-bindings: clock: add IDs for SCMI clocks on stm32mp15 reset: stm32mp1: remove stm32mp1 reset clk: hisilicon: Add clock driver for hi3559A SoC dt-bindings: Document the hi3559a clock bindings clk: si5341: Add sysfs properties to allow checking/resetting device faults clk: si5341: Add silabs,iovdd-33 property clk: si5341: Add silabs,xaxb-ext-clk property clk: si5341: Allow different output VDD_SEL values clk: si5341: Update initialization magic clk: si5341: Check for input clock presence and PLL lock on startup ...
2021-07-01kernel.h: split out panic and oops helpersAndy Shevchenko1-0/+4
kernel.h is being used as a dump for all kinds of stuff for a long time. Here is the attempt to start cleaning it up by splitting out panic and oops helpers. There are several purposes of doing this: - dropping dependency in bug.h - dropping a loop by moving out panic_notifier.h - unload kernel.h from something which has its own domain At the same time convert users tree-wide to use new headers, although for the time being include new header back to kernel.h to avoid twisted indirected includes for existing users.

2021-06-30clk: meson: regmap: switch to determine_rate for the dividersMartin Blumenstingl1-10/+9
This increases the maxmium supported frequency on 32-bit systems from 2^31 (signed long as used by clk_ops.round_rate, maximum value: approx. 2.14GHz) to 2^32 (unsigned long as used by clk_ops.determine_rate, maximum value: approx. 4.29GHz). On Meson8/8b/8m2 the HDMI PLL and it's OD (post-dividers) are capable of running at up to 2.97GHz. So switch the divider implementation in clk-regmap to clk_ops.determine_rate to support these higher frequencies on 32-bit systems.

2021-06-30clk: divider: Switch from .round_rate to .determine_rate by defaultMartin Blumenstingl1-9/+9
.determine_rate is meant to replace .round_rate. The former comes with a benefit which is especially relevant on 32-bit systems: since .determine_rate uses an "unsigned long" (compared to a "signed long" which is used by .round_rate) the maximum value on 32-bit systems increases from 2^31 (or approx. 2.14GHz) to 2^32 (or approx. 4.29GHz). Switch to a .determine_rate implementation by default so 32-bit systems can benefit from the increased maximum value as well as so we have one fewer user of .round_rate.

These are useful when running on 32-bit systems to increase the upper supported frequency limit. clk_ops.round_rate returns a signed long which limits the maximum rate on 32-bit systems to 2^31 (or approx. 2.14GHz). clk_ops.determine_rate internally uses an unsigned long so the maximum rate on 32-bit systems is 2^32 or approx. 4.29GHz.

Add sysfs property files to allow viewing the current and latched states of the input present and PLL lock bits, and allow resetting the latched fault state. This allows manual checks or automated userspace polling for faults occurring after initialization.

2021-06-28clk: si5341: Allow different output VDD_SEL valuesRobert Hancock1-26/+110
The driver was not previously programming the VDD_SEL values for each output to indicate what external VDDO voltage was used for each. Add ability to specify a regulator supplying the VDDO pin for each output of the device. The voltage of the regulator is used to automatically set the VDD_SEL value appropriately. If no regulator is specified and the chip is being reconfigured, assume 2.5V which appears to be the chip default.

2021-06-28clk: si5341: Update initialization magicRobert Hancock1-1/+3
Update the default register settings to include the VCO_RESET_CALCODE settings (set by the SiLabs ClockBuilder software but not described in the datasheet). Also update part of the initialization sequence to match ClockBuilder and the datasheet.

2021-06-28clk: si5341: Avoid divide errors due to bogus register contentsRobert Hancock1-2/+13
If the Si5341 is being initially programmed and has no stored NVM configuration, some of the register contents may contain unexpected values, such as zeros, which could cause divide by zero errors during driver initialization. Trap errors caused by zero registers or zero clock rates which could result in divide errors later in the code.

2021-06-28clk: si5341: Wait for DEVICE_READY on startupRobert Hancock1-0/+32
The Si5341 datasheet warns that before accessing any other registers, including the PAGE register, we need to wait for the DEVICE_READY register to indicate the device is ready, or the process of the device loading its state from NVM can be corrupted. Wait for DEVICE_READY on startup before continuing initialization. This is done using a raw I2C register read prior to setting up regmap to avoid any potential unwanted automatic PAGE register accesses from regmap at this stage.

2021-06-28clk: st: clkgen-fsyn: embed soc clock outputs within compatible dataAlain Volmat1-12/+101
In order to avoid relying on the old style description via the DT clock-output-names, add compatible data describing the flexgen outputs clocks for all STiH407/STiH410 and STiH418 SOCs. In order to ease transition between the two methods, this commit introduce the new compatible without removing the old method. Once DTs will be fixed, the method relying on DT clock-output-names will be removed from this driver as well as old compatibles.
