git://git.kernel.org/pub/scm/linux/kernel/git/clk/linux Pull clk updates from Stephen Boyd: "The core framework got some nice improvements this time around. We gained the ability to get struct clk pointers from a struct clk_hw so that clk providers can consume the clks they provide, if they need to do something like that. This has been a long missing part of the clk provider API that will help us move away from exposing a struct clk pointer in the struct clk_hw. Tracepoints are added for the clk_set_rate() "range" functions, similar to the tracepoints we already have for clk_set_rate() and we added a column to debugfs to help developers understand the hardware enable state of clks in case firmware or bootloader state is different than what is expected. Overall the core changes are mostly improving the clk driver writing experience. At the driver level, we have the usual collection of driver updates and new drivers for new SoCs. This time around the Qualcomm folks introduced a good handful of clk drivers for various parts of three or four SoCs. The SiFive folks added a new clk driver for their FU740 SoCs, coming in second on the diffstat and then Atmel AT91 and Amlogic SoCs had lots of work done after that for various new features. One last thing to note in the driver area is that the i.MX driver has gained a new binding to support SCU clks after being on the list for many months. It uses a two cell binding which is sort of rare in clk DT bindings. Beyond that we have the usual set of driver fixes and tweaks that come from more testing and finding out that some configuration was wrong or that a driver could support being built as a module. Summary: Core: - Add some trace points for clk_set_rate() "range" functions - Add hardware enable information to clk_summary debugfs - Replace clk-provider.h with of_clk.h when possible - Add devm variant of clk_notifier_register() - Add clk_hw_get_clk() to generate a struct clk from a struct clk_hw New Drivers: - Bindings for Canaan K210 SoC clks - Support for SiFive FU740 PRCI - Camera clks on Qualcomm SC7180 SoCs - GCC and RPMh clks on Qualcomm SDX55 SoCs - RPMh clks on Qualcomm SM8350 SoCs - LPASS clks on Qualcomm SM8250 SoCs Updates: - DVFS support for AT91 clk driver - Update git repo branch for Renesas clock drivers - Add camera (CSI) and video-in (VIN) clocks on Renesas R-Car V3U - Add RPC (QSPI/HyperFLASH) clocks on Renesas RZ/G2M, RZ/G2N, and RZ/G2E - Stop using __raw_*() I/O accessors in Renesas clk drivers - One more conversion of DT bindings to json-schema - Make i.MX clk-gate2 driver more flexible - New two cell binding for i.MX SCU clks - Drop of_match_ptr() in i.MX8 clk drivers - Add arch dependencies for Rockchip clk drivers - Fix i2s on Rockchip rk3066 - Add MIPI DSI clks on Amlogic axg and g12 SoCs - Support modular builds of Amlogic clk drivers - Fix an Amlogic Video PLL clock dependency - Samsung Kconfig dependencies updates for better compile test coverage - Refactoring of the Samsung PLL clocks driver - Small Tegra driver cleanups - Minor fixes to Ingenic and VC5 clk drivers - Cleanup patches to remove unused variables and plug memory leaks" * tag 'clk-for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/clk/linux: (134 commits) dt-binding: clock: Document canaan,k210-clk bindings dt-bindings: Add Canaan vendor prefix clk: vc5: Use "idt,voltage-microvolt" instead of "idt,voltage-microvolts" clk: ingenic: Fix divider calculation with div tables clk: sunxi-ng: Make sure divider tables have sentinel clk: s2mps11: Fix a resource leak in error handling paths in the probe function clk: mvebu: a3700: fix the XTAL MODE pin to MPP1_9 clk: si5351: Wait for bit clear after PLL reset clk: at91: sam9x60: remove atmel,osc-bypass support clk: at91: sama7g5: register cpu clock clk: at91: clk-master: re-factor master clock clk: at91: sama7g5: do not allow cpu pll to go higher than 1GHz clk: at91: sama7g5: decrease lower limit for MCK0 rate clk: at91: sama7g5: remove mck0 from parent list of other clocks clk: at91: clk-sam9x60-pll: allow runtime changes for pll clk: at91: sama7g5: add 5th divisor for mck0 layout and characteristics clk: at91: clk-master: add 5th divisor for mck master clk: at91: sama7g5: allow SYS and CPU PLLs to be exported and referenced in DT dt-bindings: clock: at91: add sama7g5 pll defines clk: at91: sama7g5: fix compilation error ...

2020-12-20clk: ingenic: Fix divider calculation with div tablesPaul Cercueil1-4/+10
The previous code assumed that a higher hardware value always resulted in a bigger divider, which is correct for the regular clocks, but is an invalid assumption when a divider table is provided for the clock. Perfect example of this is the PLL0_HALF clock, which applies a /2 divider with the hardware value 0, and a /1 divider otherwise.

git://git.kernel.org/pub/scm/linux/kernel/git/brauner/linux Pull close_range fix from Christian Brauner: "syzbot reported a bug when asking close_range() to unshare the file descriptor table and making all fds close-on-exec. If CLOSE_RANGE_UNSHARE the caller will receive a private file descriptor table in case their file descriptor table is currently shared before operating on the requested file descriptor range. For the case where the caller has requested all file descriptors to be actually closed via e.g. close_range(3, ~0U, CLOSE_RANGE_UNSHARE) the kernel knows that the caller does not need any of the file descriptors anymore and will optimize the close operation by only copying all files in the range from 0 to 3 and no others. However, if the caller requested CLOSE_RANGE_CLOEXEC together with CLOSE_RANGE_UNSHARE the caller wants to still make use of the file descriptors so the kernel needs to copy all of them and can't optimize. The original patch didn't account for this and thus could cause oopses as evidenced by the syzbot report because it assumed that all fds had been copied. Fix this by handling the CLOSE_RANGE_CLOEXEC case and copying all fds if the two flags are specified together. This should've been caught in the selftests but the original patch didn't cover this case and I didn't catch it during review. So in addition to the bugfix I'm also adding selftests. They will reliably reproduce the bug on a non-fixed kernel and allows us to catch regressions and verify correct behavior. Note, the kernel selftest tree contained a bunch of changes that made the original selftest fail to compile so there are small fixups in here make them compile without warnings" * tag 'close-range-cloexec-unshare-v5.11' of git://git.kernel.org/pub/scm/linux/kernel/git/brauner/linux: selftests/core: add regression test for CLOSE_RANGE_UNSHARE | CLOSE_RANGE_CLOEXEC selftests/core: add test for CLOSE_RANGE_UNSHARE | CLOSE_RANGE_CLOEXEC selftests/core: handle missing syscall number for close_range selftests/core: fix close_range_test build after XFAIL removal close_range: unshare all fds for CLOSE_RANGE_UNSHARE | CLOSE_RANGE_CLOEXEC

2020-12-19perf mem: Factor out a function to generate sort orderKan Liang1-14/+27
Now, "--phys-data" is the only option which impacts the sort order. A simple "if else" is enough to handle the option. But there will be more options added, e.g. "--data-page-size", which also impact the sort order. The code will become too complex to be maintained. Divide the sort order string into several small pieces. The first piece is always the default sort string for LOAD/STORE. Appends the specific sort string if related option is applied.

2020-12-19clk: bcm: dvp: drop a variable that is assigned to onlyUwe Kleine-König1-2/+1
The third parameter to devm_platform_get_and_ioremap_resource() is used only to provide the used resource. As this variable isn't used afterwards, switch to the function devm_platform_ioremap_resource() which doesn't provide this output parameter.
