* soc: versatile: remove unnecessary static in realview_soc_probe()Gustavo A. R. Silva2017-08-161-1/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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.

| | | | | | | | | 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 <arnd@arndb.de> Signed-off-by: Linus Walleij <linus.walleij@linaro.org>

* drivers/soc: Convert non-modular soc-realview to use builtin_platform_driverPaul Gortmaker2015-06-161-1/+1
| | | | | | | | | | | | | | | | | | 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 <module.h> 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.

| | | | | | | | | | | | | | | | | | | | This creates a new SoC bus driver for the ARM Integrator family core modules to register the SoC bus and provide sysfs info for the core module.

* soc: add driver for the ARM RealViewLinus Walleij2014-09-263-0/+155
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 <linus.walleij@linaro.org> Signed-off-by: Arnd Bergmann <arnd@arndb.de> Conflicts: drivers/soc/Kconfig drivers/soc/Makefile
