2021-10-14clk: versatile: hide clock drivers from non-ARM usersJean Delvare1-0/+1
Commit 419b3ab6987f ("clk: versatile: remove dependency on ARCH_*") made the whole menu of ARM reference clock drivers visible on all architectures. I can't see how this is an improvement for non-ARM users. Unless build-testing, there is no point on presenting ARM-only clock drivers on other architectures.

2021-06-01clk: versatile: remove dependency on ARCH_*Peter Collingbourne1-2/+0
It is now possible to build a modular kernel for vexpress by not setting CONFIG_ARCH_VEXPRESS=y and instead setting =m on the drivers that it normally implies. This is with the exception of CLK_VEXPRESS_OSC which is currently hidden behind a dependency on one of several ARCH_* variables. Remove that dependency so that CLK_VEXPRESS_OSC may be enabled without it.

2020-06-14treewide: replace '---help---' in Kconfig files with 'help'Masahiro Yamada1-3/+3
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 <[email protected]>

2020-05-05clk: versatile: Rework kconfig structureRob Herring1-10/+12
CONFIG_COMMON_CLK_VERSATILE doesn't really do anything other than hiding Arm Ltd reference platform clock drivers. It is both selected by the platforms that need it and has a 'depends on' for those platforms. Let's drop the selects and convert CONFIG_COMMON_CLK_VERSATILE into a menuconfig entry. With this make CONFIG_ICST visible. Move the 'select REGMAP_MMIO' to the drivers that require it (SP810 did not). This also has the side effect of enabling CONFIG_ICST for COMPILE_TEST as it was not visible before.

2017-04-07ARM/clk: move the ICST library to drivers/clkLinus Walleij1-0/+3
This moves the ICST clock divider helper library from arch/arm/common to drivers/clk/versatile so it is maintained with the other clock drivers. We keep the structure as a helper library intact and do not fuse it with the clk-icst.c Versatile ICST clock driver: there may be other users out there that need to use this library for their clocking, and then it will be helpful to keep the library contained. (The icst.[c|h] files could just be moved to drivers/clk/lib or a similar location to share the library.) Acked-by: Stephen Boyd <[email protected]> Signed-off-by: Linus Walleij <[email protected]>

2015-12-15ARM: versatile: switch to DT only booting and remove legacy codeRob Herring1-1/+3
With DT support for clocks, irqchips, timers, and PCI now in place, DT based booting has feature parity with non-DT legacy boot. The final piece is actually enabling common clock support on Versatile. Enabling full DT support requires either removing the old Versatile clock code, updating the legacy boot to use the common clock code, or making DT and legacy boot mutually exclusive. Given that removing legacy boot code is the goal anyway, I am going with the 1st option.

These drivers only have runtime but no build time dependencies so can be built for testing purposes if the Kconfig COMPILE_TEST option is enabled. This is useful to have more build coverage and make sure that drivers are not affected by changes that could cause build regressions.
