soc: realview: Use custom soc attribute group instead of device_create_file

2020-07-06T08:48:05Z

Commit c31e73121f4c ("base: soc: Handle custom soc information sysfs entries") introduced custom soc attribute group in soc_device_attribute structure but there are no users treewide. While trying to understand the motivation and tried to use it, it was found lot of existing custom attributes can moved to use it instead of device_create_file. Though most of these never remove/cleanup the custom attribute as they never call soc_device_unregister, using these custom attribute group eliminate the need for any cleanup as the driver infrastructure will take care of that. Let us remove device_create_file and start using the custom attribute group in soc_device_attribute.

soc: realview: Switch to use DEVICE_ATTR_RO()

2020-07-06T08:48:05Z

Move device attributes to DEVICE_ATTR_RO() as that would make things a lot more "obvious" what is happening over the existing __ATTR usage.

soc: versatile: remove unnecessary static in realview_soc_probe()

2017-08-16T20:28:27Z

Remove unnecessary static on local variables syscon_regmap. Such variables are initialized before being used, on every execution path throughout the functions. The static has no benefit and, removing it reduces the object file size. This issue was detected using Coccinelle and the following semantic patch: @bad exists@ position p; identifier x; type T; @@ static T x@p; ... x = <+...x...+> @@ identifier x; expression e; type T; position p != bad.p; @@ -static T x@p; ... when != x when strict ?x = e; In the following log you can see the difference in the object file size. This log is the output of the size command, before and after the code change: before: text data bss dec hex filename 3339 2104 128 5571 15c3 drivers/soc/versatile/soc-realview.o after: text data bss dec hex filename 3321 2048 64 5433 1539 drivers/soc/versatile/soc-realview.o Signed-off-by: Gustavo A.

soc: versatile: dynamically detect RealView HBI numbers

We cannot pile all numbers on this list, just print the three hex digits representing the board ID so we can handle all the new RealView boards. Cc: Arnd Bergmann Signed-off-by: Linus Walleij

drivers/soc: Convert non-modular soc-realview to use builtin_platform_driver

2015-06-16T18:12:38Z

This file depends on Kconfig SOC_REALVIEW which is a bool, so we use the appropriate registration function, which avoids us relying on an implicit inclusion of which we are doing currently. While this currently works, we really don't want to be including the module.h header in non-modular code, which we'd be forced to do, pending some upcoming code relocation from init.h into module.h. So we fix it now by using the non-modular equivalent. Cc: Arnd Bergmann Cc: Linus Walleij Acked-by: Linus Walleij Cc: Axel Lin Signed-off-by: Paul Gortmaker

soc: add driver for the ARM RealView

2014-09-25T22:26:10Z

This adds a SoC driver to be used by the ARM RealView reference boards. We create the "versatile" directory to hold the different ARM reference designs as per the pattern of the clk directory layout. The driver utilze the syscon to get to the register needed. After this we can use sysfs to get at some SoC properties on RealView DT variants like this: > cd /sysbus/soc/devices/soc0 > ls board family machine power subsystem build fpga manufacturer soc_id uevent > cat family Versatile > cat fpga Multi-layer AXI > cat board HBI-0147 > cat build 03 Signed-off-by: Linus Walleij Signed-off-by: Arnd Bergmann Conflicts: drivers/soc/Kconfig drivers/soc/Makefile
