2022-08-30Merge tag 'samsung-clk-6.1' of https://git.kernel.org/pub/scm/linux/kernel/git/krzk/linux into clk-samsungStephen Boyd9-55/+1620
Pull Samsung clk driverd updates from Krzysztof Kozlowski: - 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. This is an acceptable ABI break: recently developed/added platform so without legacies, acked by known users/developers. - ExynosAutov9: add few missing Peric 0/1 gates. - ExynosAutov9: correct register offsets of few Peric 0/1 clocks. - Minor code improvements (use of_device_get_match_data() helper, code style). - Add Krzysztof Kozlowski as co-maintainer of Samsung SoC clocks, as he already maintainers that architecture/platform. * tag 'samsung-clk-6.1' of https://git.kernel.org/pub/scm/linux/kernel/git/krzk/linux: clk: samsung: MAINTAINERS: add Krzysztof Kozlowski clk: samsung: exynos850: Implement CMU_MFCMSCL domain clk: samsung: exynos850: Implement CMU_IS domain clk: samsung: exynos850: Implement CMU_AUD domain clk: samsung: exynos850: Style fixes clk: samsung: exynosautov9: add fsys1 clock support clk: samsung: exynosautov9: add fsys0 clock support clk: samsung: exynosautov9: correct register offsets of peric0/c1 clk: samsung: exynosautov9: add missing gate clks for peric0/c1 dt-bindings: clock: exynos850: Add Exynos850 CMU_MFCMSCL dt-bindings: clock: exynos850: Add Exynos850 CMU_IS dt-bindings: clock: exynos850: Add Exynos850 CMU_AUD dt-bindings: clock: exynosautov9: add schema for cmu_fsys0/1 dt-bindings: clock: exynosautov9: add fsys1 clock definitions dt-bindings: clock: exynosautov9: add fys0 clock definitions clk: samsung: exynos7885: Add TREX clocks clk: samsung: exynos7885: Implement CMU_FSYS domain dt-bindings: clock: exynosautov9: correct clock numbering of peric0/c1 clk: samsung: exynos-clkout: Use of_device_get_match_data()

2022-08-23clk: samsung: exynos850: Implement CMU_MFCMSCL domainSam Protsenko1-0/+176
CMU_MFCMSCL clock domain provides clocks for MFC (Multi-Format Codec), JPEG Codec and Scaler IP-cores. According to Exynos850 TRM, CMU_MFCMSCL generates MFC, M2M, MCSC and JPEG clocks for BLK_MFCMSCL. This patch adds next clocks: - bus clocks in CMU_TOP for CMU_MFCMSCL - all internal CMU_MFCMSCL clocks - leaf clocks for MFCMSCL, TZPC (TrustZone Protection Controller), JPEG codec, M2M (Memory-to-Memory), MCSC (Multi-Channel Scaler), MFC (Multi-Format Codec), PPMU (Platform Performance Monitoring Unit), SysMMU and SysReg MFCMSCL related gate clocks in CMU_TOP were marked as CLK_IS_CRITICAL, because: 1. All of those have to be enabled in order to read /sys/kernel/debug/clk/clk_summary file 2. When some user driver (e.g. exynos-sysmmu) disables some derived leaf clock, it can lead to CMU_TOP clocks disable, which then makes the system hang. To prevent that, the CLK_IS_CRITICAL flag is used, as CLK_IGNORE_UNUSED is not enough.

CMU_AUD clock domain provides clocks for ABOX IP-core (audio subsystem). According to Exynos850 TRM, CMU_AUD generates Cortex-A32 clock, bus clock and audio clocks for BLK_AUD. This patch adds next clocks: - bus clocks in CMU_TOP needed for CMU_AUD - all internal CMU_AUD clocks - leaf clocks for Cortex-A32, Speedy FM, UAIF0..UAIF6 (Unified Audio Interface), CNT (counter), ABOX IP-core, ASB (Asynchronous Bridge), DAP (Debug Access Port), I2S Codec MCLK, D_TZPC (TrustZone Protection Controller), GPIO, PPMU (Platform Performance Monitoring Unit), SysMMU, SysReg and WDT ABOX clock was marked as CLK_IGNORE_UNUSED, as system hangs on boot otherwise.

2022-08-23clk: samsung: exynos7885: Add TREX clocksDavid Virag1-7/+42
TREX D Core and P core clocks seem to be related to the BTS (Bus Traffic Shaper) inside the Exynos7885 SoC, and are needed for the SoC to function correctly. When clocks are cut from TREX D Core, the eMMC and the framebuffer stops working properly. Other unknown things may stop working as well. When clocks are cut from TREX P Core, the system locks up needing a hard reset. Add these clocks and mark them critical so that they are always on.

2022-08-13afs: Enable multipage folio supportDavid Howells2-1/+3
Enable multipage folio support for the afs filesystem. Support has already been implemented in netfslib, fscache and cachefiles and in most of afs, but I've waited for Matthew Wilcox's latest folio changes. Note that it does require a change to afs_write_begin() to return the correct subpage. This is a "temporary" change as we're working on getting rid of the need for ->write_begin() and ->write_end() completely, at least as far as network filesystems are concerned - but it doesn't prevent afs from making use of the capability.

2022-08-13perf test: Refactor shell tests allowing subdirsCarsten Haitzler4-134/+238
This is a prelude to adding more tests to shell tests and in order to support putting those tests into subdirectories, I need to change the test code that scans/finds and runs them. To support subdirs I have to recurse so it's time to refactor the code to allow this and centralize the shell script finding into one location and only one single scan that builds a list of all the found tests in memory instead of it being duplicated in 3 places. This code also optimizes things like knowing the max width of desciption strings (as we can do that while we scan instead of a whole new pass of opening files). It also more cleanly filters scripts to see only *.sh files thus skipping random other files in directories like *~ backup files, other random junk/data files that may appear and the scripts must be executable to make the cut (this ensures the script lib dir is not seen as scripts to run). This avoids perf test running previous older versions of test scripts that are editor backup files as well as skipping perf.data files that may appear and so on.
