2020-02-03Merge tag 'clk-for-linus' of ↵Linus Torvalds
git://git.kernel.org/pub/scm/linux/kernel/git/clk/linux Pull clk updates from Stephen Boyd: "There are a few changes to the core framework this time around, in addition to the normal collection of driver updates to support new SoCs, fix incorrect data, and convert various drivers to clk_hw based APIs. In the core, we allow clk_ops::init() to return an error code now so that we can fail clk registration if the callback does something like fail to allocate memory. We also add a new "terminate" clk_op so that things done in clk_ops::init() can be undone, e.g. free memory. We also spit out a warning now when critical clks fail to enable and we support changing clk rates and enable/disable state through debugfs when developers compile the kernel themselves. On the driver front, we get support for what seems like a lot of Qualcomm and NXP SoCs given that those vendors dominate the diffstat. There are a couple new drivers for Xilinx and Amlogic SoCs too. The updates are all small things like fixing the way glitch free muxes switch parents, avoiding div-by-zero problems, or fixing data like parent names. See the updates section below for more details. Finally, the "basic" clk types have been converted to support specifying parents with clk_hw pointers. This work includes an overhaul of the fixed-rate clk type to be more modern by using clk_hw APIs. Core: - Let clk_ops::init() return an error code - Add a clk_ops::terminate() callback to undo clk_ops::init() - Warn about critical clks that fail to enable or prepare - Support dangerous debugfs actions on clks with dead code New Drivers: - Support for Xilinx Versal platform clks - Display clk controller on qcom sc7180 - Video clk controller on qcom sc7180 - Graphics clk controller on qcom sc7180 - CPU PLLs for qcom msm8916 - Move qcom msm8974 gfx3d clk to RPM control - Display port clk support on qcom sdm845 SoCs - Global clk controller on qcom ipq6018 - Add a driver for BCLK of Freescale SAI cores - Add cam, vpe and sgx clock support for TI dra7 - Add aess clock support for TI omap5 - Enable clks for CPUfreq on Allwinner A64 SoCs - Add Amlogic meson8b DDR clock controller - Add input clocks to Amlogic meson8b controllers - Add SPIBSC (SPI FLASH) clock on Renesas RZ/A2 - i.MX8MP clk driver support Updates: - Convert gpio, fixed-factor, mux, gate, divider basic clks to hw based APIs - Detect more PRMCU variants in ux500 driver - Adjust the composite clk type to new way of describing clk parents - Fixes for clk controllers on qcom msm8998 SoCs - Fix gmac main clock for TI dra7 - Move TI dra7-atl clock header to correct location - Fix hidden node name dependency on TI clkctrl clocks - Fix Amlogic meson8b mali clock update using the glitch free mux - Fix Amlogic pll driver division by zero at init - Prepare for split of Renesas R-Car H3 ES1.x and ES2.0+ config symbols - Switch more i.MX clk drivers to clk_hw based APIs - Disable non-functional divider between pll4_audio_div and pll4_post_div on imx6q - Fix watchdog2 clock name typo in imx7ulp clock driver - Set CLK_GET_RATE_NOCACHE flag for DRAM related clocks on i.MX8M SoCs - Suppress bind attrs for i.MX8M clock driver - Add a big comment in imx8qxp-lpcg driver to tell why devm_platform_ioremap_resource() shouldn't be used for the driver - A correction on i.MX8MN usb1_ctrl parent clock setting" * tag 'clk-for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/clk/linux: (140 commits) dt/bindings: clk: fsl,plldig: Drop 'bindings' from schema id clk: ls1028a: Fix warning on clamp() usage clk: qoriq: add ls1088a hwaccel clocks support clk: ls1028a: Add clock driver for Display output interface dt/bindings: clk: Add YAML schemas for LS1028A Display Clock bindings clk: fsl-sai: new driver dt-bindings: clock: document the fsl-sai driver clk: composite: add _register_composite_pdata() variants clk: qcom: rpmh: Sort OF match table dt-bindings: fix warnings in validation of qcom,gcc.yaml dt-binding: fix compilation error of the example in qcom,gcc.yaml clk: zynqmp: Add support for clock with CLK_DIVIDER_POWER_OF_TWO flag clk: zynqmp: Fix divider calculation clk: zynqmp: Add support for get max divider clk: zynqmp: Warn user if clock user are more than allowed clk: zynqmp: Extend driver for versal dt-bindings: clock: Add bindings for versal clock driver clk: ti: clkctrl: Fix hidden dependency to node name clk: ti: add clkctrl data dra7 sgx clk: ti: omap5: Add missing AESS clock ...

2020-02-03platform/chrome: cros_ec: Match implementation with headersEnric Balletbo i Serra
The 'cros_ec' core driver is the common interface for the cros_ec transport drivers to do the shared operations to register, unregister, suspend, resume and handle_event. The interface is provided by including the header 'include/linux/platform_data/cros_ec_proto.h', however, instead of have the implementation of these functions in cros_ec_proto.c, it is in 'cros_ec.c', which is a different kernel module. Apart from being a bad practice, this can induce confusions allowing the users of the cros_ec protocol to call these functions. The register, unregister, suspend, resume and handle_event functions *should* only be called by the different transport drivers (i2c, spi, lpc, etc.), so make this a bit less confusing by moving these functions from the public in-kernel space to a private include in platform/chrome, and then, the interface for cros_ec module and for the cros_ec_proto module is clean.

writeback_store Currently when an error code -EIO or -ENOSPC in the for-loop of writeback_store the error code is being overwritten by a ret = len assignment at the end of the function and the error codes are being lost. Fix this by assigning ret = len at the start of the function and remove the assignment from the end, hence allowing ret to be preserved when error codes are assigned to it.

2020-01-31zram: try to avoid worst-case scenario on same element pagesTaejoon Song
The worst-case scenario on finding same element pages is that almost all elements are same at the first glance but only last few elements are different. Since the same element tends to be grouped from the beginning of the pages, if we check the first element with the last element before looping through all elements, we might have some chances to quickly detect non-same element pages. 1. Test is done under LG webOS TV (64-bit arch) 2. Dump the swap-out pages (~819200 pages) 3. Analyze the pages with simple test script which counts the iteration number and measures the speed at off-line Under 64-bit arch, the worst iteration count is PAGE_SIZE / 8 bytes = 512. The speed is based on the time to consume page_same_filled() function only. The result, on average, is listed as below: Num of Iter Speed(MB/s) Looping-Forward (Orig) 38 99265 Looping-Backward 36 102725 Last-element-check (This Patch) 33 125072 The result shows that the average iteration count decreases by 13% and the speed increases by 25% with this patch. This patch does not increase the overall time complexity, though. I also ran simpler version which uses backward loop. Just looping backward also makes some improvement, but less than this patch.
