treewide: replace '---help---' in Kconfig files with 'help'

2020-06-13T16:57:21Z

Since commit 84af7a6194e4 ("checkpatch: kconfig: prefer 'help' over '---help---'"), the number of '---help---' has been gradually decreasing, but there are still more than 2400 instances. This commit finishes the conversion. While I touched the lines, I also fixed the indentation. There are a variety of indentation styles found. a) 4 spaces + '---help---' b) 7 spaces + '---help---' c) 8 spaces + '---help---' d) 1 space + 1 tab + '---help---' e) 1 tab + '---help---' (correct indentation) f) 1 tab + 1 space + '---help---' g) 1 tab + 2 spaces + '---help---' In order to convert all of them to 1 tab + 'help', I ran the following commend: $ find . -name 'Kconfig*' | xargs sed -i 's/^[[:space:]]*---help---/\thelp/' Signed-off-by: Masahiro Yamada

Pull clk updates from Stephen Boyd: "This time around we have four lines of diff in the core framework, removing a function that isn't used anymore. Otherwise the main new thing for the common clk framework is that it is selectable in the Kconfig language now. Hopefully this will let clk drivers and clk consumers be testable on more than the architectures that support the clk framework. The goal is to introduce some Kunit tests for the framework. Outside of the core framework we have the usual set of various driver updates and non-critical fixes. The dirstat shows that the new Baikal-T1 driver is the largest addition this time around in terms of lines of code. After that the x86 (Intel), Qualcomm, and Mediatek drivers introduce many lines to support new or upcoming SoCs. After that the dirstat shows the usual suspects working on their SoC support by fixing minor bugs, correcting data and converting some of their DT bindings to YAML. Core: - Allow the COMMON_CLK config to be selectable New Drivers: - Clk driver for Baikal-T1 SoCs - Mediatek MT6765 clock support - Support for Intel Agilex clks - Add support for X1830 and X1000 Ingenic SoC clk controllers - Add support for the new Renesas RZ/G1H (R8A7742) SoC - Add support for Qualcomm's MSM8939 Generic Clock Controller Updates: - Support IDT VersaClock 5P49V5925 - Bunch of updates for HSDK clock generation unit (CGU) driver - Start making audio and GPU clks work on Marvell MMP2/MMP3 SoCs - Add some GPU, NPU, and UFS clks to Qualcomm SM8150 driver - Enable supply regulators for GPU gdscs on Qualcomm SoCs - Add support for Si5342, Si5344 and Si5345 chips - Support custom flags in Xilinx zynq firmware - Various small fixes to the Xilinx clk driver - A single minor rounding fix for the legacy Allwinner clock support - A few patches from Abel Vesa as preparation of adding audiomix clock support on i.MX - A couple of cleanups from Anson Huang for i.MX clk-sscg-pll and clk-pllv3 drivers - Drop dependency on ARM64 for i.MX8M clock driver, to support aarch32 mode on aarch64 hardware - A series from Peng Fan to improve i.MX8M clock drivers, using composite clock for core and bus clk slice - Set a better parent clock for flexcan on i.MX6UL to support CiA102 defined bit rates - A couple changes for EMC frequency scaling on Tegra210 - Support for CPU frequency scaling on Tegra20/Tegra30 - New clk gate for CSI test pattern generator on Tegra210 - Regression fixes for Samsung exynos542x and exynos5433 SoCs - Use of fallthrough; attribute for Samsung s3c24xx - Updates and fixup HDMI and video clocks on Meson8b - Fixup reset polarity on Meson8b - Fix GPU glitch free mux switch on Meson gx and g12 - A minor fix for the currently unused suspend/resume handling on Renesas RZ/A1 and RZ/A2 - Two more conversions of Renesas DT bindings to json-schema - Add support for the USB 2.0 clock selector on Renesas R-Car M3-W+" * tag 'clk-for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/clk/linux: (155 commits) clk: mediatek: Remove ifr{0,1}_cfg_regs structures clk: baikal-t1: remove redundant assignment to variable 'divider' clk: baikal-t1: fix spelling mistake "Uncompatible" -> "Incompatible" dt-bindings: clock: Add a missing include to MMP Audio Clock binding dt: Add bindings for IDT VersaClock 5P49V5925 clk: vc5: Add support for IDT VersaClock 5P49V6965 clk: Add Baikal-T1 CCU Dividers driver clk: Add Baikal-T1 CCU PLLs driver dt-bindings: clk: Add Baikal-T1 CCU Dividers binding dt-bindings: clk: Add Baikal-T1 CCU PLLs binding clk: mediatek: assign the initial value to clk_init_data of mtk_mux clk: mediatek: Add MT6765 clock support clk: mediatek: add mt6765 clock IDs dt-bindings: clock: mediatek: document clk bindings vcodecsys for Mediatek MT6765 SoC dt-bindings: clock: mediatek: document clk bindings mipi0a for Mediatek MT6765 SoC dt-bindings: clock: mediatek: document clk bindings for Mediatek MT6765 SoC CLK: HSDK: CGU: add support for 148.5MHz clock CLK: HSDK: CGU: support PLL bypassing CLK: HSDK: CGU: check if PLL is bypassed first clk: clk-si5341: Add support for the Si5345 series ...

Pull ARM SoC updates from Arnd Bergmann: "One new platform gets added, the Realtek RTD1195, which is an older Cortex-a7 based relative of the RTD12xx chips that are already supported in arch/arm64. The platform may also be extended to support running 32-bit kernels on those 64-bit chips for memory-constrained machines. In the Renesas shmobile platform, we gain support for "RZ/G1H" or R8A7742, an eight-core chip based on Cortex-A15 and Cortex-A7 cores, originally released in 2016 as one of the last high-end 32-bit designs. There is ongoing cleanup for the integrator, tegra, imx, and omap2 platforms, with integrator getting very close to the goal of having zero code in arch/arm/, and omap2 moving more of the chip specifics from old board code into device tree files. The Versatile Express platform is made more modular, with built-in drivers now becoming loadable modules. This is part of a greater effort for the Android OS to have a common kernel binary for all platforms and any platform specific code in loadable modules. The PXA platform drops support for Compulab's pxa2xx boards that had rather unusual flash and PCI drivers but no known users remaining. All device drivers specific to those boards can now get removed as well. Across platforms, there is ongoing cleanup, with Geert and Rob revisiting some a lot of Kconfig options" * tag 'arm-soc-5.8' of git://git.kernel.org/pub/scm/linux/kernel/git/soc/soc: (94 commits) ARM: omap2: fix omap5_realtime_timer_init definition ARM: zynq: Don't select CONFIG_ICST ARM: OMAP2+: Fix regression for using local timer on non-SMP SoCs clk: versatile: Fix kconfig dependency on COMMON_CLK_VERSATILE ARM: davinci: fix build failure without I2C power: reset: vexpress: fix build issue power: vexpress: cleanup: use builtin_platform_driver power: vexpress: add suppress_bind_attrs to true Revert "ARM: vexpress: Don't select VEXPRESS_CONFIG" MAINTAINERS: pxa: remove Compulab arm/pxa support ARM: pxa: remove Compulab pxa2xx boards bus: arm-integrator-lm: Fix return value check in integrator_ap_lm_probe() soc: imx: move cpu code to drivers/soc/imx ARM: imx: move cpu definitions into a header ARM: imx: use device_initcall for imx_soc_device_init ARM: imx: pcm037: make pcm970_sja1000_platform_data static bus: ti-sysc: Timers no longer need legacy quirk handling ARM: OMAP2+: Drop old timer code for dmtimer and 32k counter ARM: dts: Configure system timers for omap2 ARM: dts: Configure system timers for ti81xx ...

VExpress modularization This series enables building various Versatile Express platform drivers as modules. The primary target is the Fast Model FVP which is supported in Android. As Android is moving towards their GKI, or generic kernel, the hardware support has to be in modules. Currently ARCH_VEXPRESS enables several built-in only drivers. Some of these are needed, but some are only needed for older 32-bit VExpress platforms and can just be disabled. * tag 'vexpress-modules-for-soc-v2' of git://git.kernel.org/pub/scm/linux/kernel/git/robh/linux: ARM: vexpress: Don't select VEXPRESS_CONFIG bus: vexpress-config: Support building as module vexpress: Move setting master site to vexpress-config bus bus: vexpress-config: simplify config bus probing bus: vexpress-config: Merge vexpress-syscfg into vexpress-config mfd: vexpress-sysreg: Support building as a module mfd: vexpress-sysreg: Use devres API variants mfd: vexpress-sysreg: Drop unused syscon child devices mfd: vexpress-sysreg: Drop selecting CONFIG_CLKSRC_MMIO clk: vexpress-osc: Support building as a module clk: vexpress-osc: Use the devres clock API variants clk: versatile: Only enable SP810 on 32-bit by default clk: versatile: Rework kconfig structure amba: Retry adding deferred devices at late_initcall arm64: vexpress: Don't select CONFIG_POWER_RESET_VEXPRESS ARM: vexpress: Move vexpress_flags_set() into arch code Signed-off-by: Arnd Bergmann
