devm_clk_hw_register_fixed_factor_release(), the release function for the devm_clk_hw_register_fixed_factor(), calls clk_hw_unregister_fixed_factor(), which will kfree() the clock. However after that the devres functions will also kfree the allocated data, resulting in double free/memory corruption. Just call clk_hw_unregister() instead, leaving kfree() to devres code.

2021-04-07clk: exynos7: Mark aclk_fsys1_200 as criticalPaweł Chmiel
This clock must be always enabled to allow access to any registers in fsys1 CMU. Until proper solution based on runtime PM is applied (similar to what was done for Exynos5433), mark that clock as critical so it won't be disabled. It was observed on Samsung Galaxy S6 device (based on Exynos7420), where UFS module is probed before pmic used to power that device. In this case defer probe was happening and that clock was disabled by UFS driver, causing whole boot to hang on next CMU access.

2021-04-04clk: imx: Fix reparenting of UARTs not associated with stdoutAdam Ford
Most if not all i.MX SoC's call a function which enables all UARTS. This is a problem for users who need to re-parent the clock source, because any attempt to change the parent results in an busy error due to the fact that the clocks have been enabled already. clk: failed to reparent uart1 to sys_pll1_80m: -16 Instead of pre-initializing all UARTS, scan the device tree to see which UART clocks are associated to stdout, and only enable those UART clocks if it's needed early. This will move initialization of the remaining clocks until after the parenting of the clocks. When the clocks are shutdown, this mechanism will also disable any clocks that were pre-initialized.

2021-04-02clk: fix invalid usage of list cursor in unregisterLukasz Bartosik
Fix invalid usage of a list_for_each_entry cursor in clk_notifier_unregister(). When list is empty or if the list is completely traversed (without breaking from the loop on one of the entries) then the list cursor does not point to a valid entry and therefore should not be used.

git://git.kernel.org/pub/scm/linux/kernel/git/tmlind/linux-omap into arm/drivers Driver changes for omaps for genpd support for v5.13 In order to move omap4/5 and dra7 to probe with devicetree data and genpd, we need to patch the related drivers to prepare. These are mostly ti-sysc interconnect target module driver changes and soc init changes. However, there are minor changes to other drivers too. There are changes for pci-dra7xx probe, omap-prm idle configuration, and a omap5 clock change: - ti-sysc needs iorange check improved when the interconnect target module has no control registers listed - ti-sysc needs to probe l4_wkup and l4_cfg interconnects first to avoid issues with missing resources and unnecessary deferred probe - ti-sysc debug option can now detect more devices - ti-sysc now warns if an old incomplete devicetree data is found as we now rely on it being complete for am3 and 4 - soc init code needs to check for prcm and prm nodes for omap4/5 and dra7 - omap-prm driver needs to enable autoidle retention support for omap4 - omap5 clocks are missing gpmc and ocmc clock registers - pci-dra7xx now needs to use builtin_platform_driver instead of using builtin_platform_driver_probe for deferred probe to work There are also few minor non-urgent fixes: - soc init code pdata_quirks_init_clocks should be static - ti-sysc has few unneeded semiconon typos - ti-sysc can use kzalloc instead of kcalloc for a single element * tag 'omap-for-v5.13/ti-sysc-signed' of git://git.kernel.org/pub/scm/linux/kernel/git/tmlind/linux-omap: bus: ti-sysc: Use kzalloc for allocating only one thing bus: ti-sysc: remove unneeded semicolon ARM: OMAP2+: Make symbol 'pdata_quirks_init_clocks' static PCI: pci-dra7xx: Prepare for deferred probe with module_platform_driver clk: ti: omap5: Add missing gpmc and ocmc clkctrl soc: ti: omap-prm: Allow hardware supported retention when idle ARM: OMAP2+: Init both prm and prcm nodes early for clocks bus: ti-sysc: Check for old incomplete dtb bus: ti-sysc: Detect more modules for debugging bus: ti-sysc: Probe for l4_wkup and l4_cfg interconnect devices first bus: ti-sysc: Fix initializing module_pa for modules without sysc register ARM: dts: Fix moving mmc devices with aliases for omap4 & 5 ARM: dts: Drop duplicate sha2md5_fck to fix clk_disable race soc: ti: omap-prm: Fix occasional abort on reset deassert for dra7 iva bus: ti-sysc: Fix warning on unbind if reset is not deasserted ARM: OMAP2+: Fix smartreflex init regression after dropping legacy data soc: ti: omap-prm: Fix reboot issue with invalid pcie reset map for dra7 ARM: dts: am33xx: add aliases for mmc interfaces bus: omap_l3_noc: mark l3 irqs as IRQF_NO_THREAD Link: https://lore.kernel.org/r/pull-1617004205-537424@atomide.com Signed-off-by: Arnd Bergmann <arnd@arndb.de>

2021-03-30clk: renesas: Zero init clk_init_dataGeert Uytterhoeven
As clk_core_populate_parent_map() checks clk_init_data.num_parents first, and checks clk_init_data.parent_names[] before clk_init_data.parent_data[] and clk_init_data.parent_hws[], leaving the latter uninitialized doesn't do harm for now. However, it is better to play it safe, and initialize all clk_init_data structures to zeroes, to avoid any current and future members containing uninitialized data. Remove a few explicit zero initializers, which are now superfluous.

2021-03-29clk: qcom: camcc: Update the clock ops for the SC7180Taniya Das
Some of the RCGs could be always ON from the XO source and could be used as the clock on signal for the GDSC to be operational. In the cases where the GDSCs are parked at different source with the source clock disabled, it could lead to the GDSC to be stuck at ON/OFF during gdsc disable/enable. Thus park the RCGs at XO during clock disable and update the rcg_ops to use the shared_ops.

2021-03-24clk: tegra: Add PLLE HW power sequencer controlJC Kuo
PLLE has a hardware power sequencer logic which is a state machine that can power on/off PLLE without any software intervention. The sequencer has two inputs, one from XUSB UPHY PLL and the other from SATA UPHY PLL. PLLE provides reference clock to XUSB and SATA UPHY PLLs. When both of the downstream PLLs are powered-off, PLLE hardware power sequencer will automatically power off PLLE for power saving. XUSB and SATA UPHY PLLs also have their own hardware power sequencer logic. XUSB UPHY PLL is shared between XUSB SuperSpeed ports and PCIE controllers. The XUSB UPHY PLL hardware power sequencer has inputs from XUSB and PCIE. When all of the XUSB SuperSpeed ports and PCIE controllers are in low power state, XUSB UPHY PLL hardware power sequencer automatically power off PLL and flags idle to PLLE hardware power sequencer. Similar applies to SATA UPHY PLL. PLLE hardware power sequencer has to be enabled after both downstream sequencers are enabled. This commit adds two helper functions: 1. tegra210_plle_hw_sequence_start() for XUSB PADCTL driver to enable PLLE hardware sequencer at proper time. 2. tegra210_plle_hw_sequence_is_enabled() for XUSB PADCTL driver to check whether PLLE hardware sequencer has been enabled or not.

2021-03-23clk: socfpga: use ARCH_INTEL_SOCFPGA also for 32-bit ARM SoCs (and compile test)Krzysztof Kozlowski
ARCH_SOCFPGA is being renamed to ARCH_INTEL_SOCFPGA so adjust the 32-bit ARM drivers to rely on new symbol. There is little point to share clock controller drivers between 32-bit and 64-bit platforms because there will not be a generic image for both of them. Therefore add a new Kconfig entry for building 32-bit clock driverss, similar to one for 64-bit. This allows enabling compile testing.
