soc: bcm: Move power-domain drivers to the genpd dir

2023-07-11T13:30:09+00:00

To simplify with maintenance let's move the bcm power-domain drivers to the new genpd directory. Going forward, patches are intended to be managed through a separate git tree, according to MAINTAINERS. While moving the drivers, we end up with a directory for bcm63xx that only contains a Kconfig file, which seems a bit silly. Let's therefore also move the Kconfig options into the Kconfig file a directory above, as it allows us to drop the directory too.

soc: bcm: brcmstb: biuctrl: fix of_iomap leak

2023-04-03T20:37:24+00:00

Smatch reports: drivers/soc/bcm/brcmstb/biuctrl.c:291 setup_hifcpubiuctrl_regs() warn: 'cpubiuctrl_base' from of_iomap() not released on lines: 291. This is because in setup_hifcpubiuctrl_regs(), cpubiuctrl_base is not released when handle error, which may cause a leak. To fix this, iounmap is added when handle error.

kbuild, soc: bcm: bcm2835-power: remove MODULE_LICENSE in non-modules

2023-03-14T21:07:17+00:00

Since commit 8b41fc4454e ("kbuild: create modules.builtin without Makefile.modbuiltin or tristate.conf"), MODULE_LICENSE declarations are used to identify modules. As a consequence, uses of the macro in non-modules will cause modprobe to misidentify their containing object file as a module when it is not (false positives), and modprobe might succeed rather than failing with a suitable error message. So remove it in the files in this commit, none of which can be built as modules.

ARM: 9263/1: use .arch directives instead of assembler command line flags

2022-11-08T18:36:17+00:00

Similar to commit a6c30873ee4a ("ARM: 8989/1: use .fpu assembler directives instead of assembler arguments"). GCC and GNU binutils support setting the "sub arch" via -march=, -Wa,-march, target function attribute, and .arch assembler directive. Clang was missing support for -Wa,-march=, but this was implemented in clang-13. The behavior of both GCC and Clang is to prefer -Wa,-march= over -march= for assembler and assembler-with-cpp sources, but Clang will warn about the -march= being unused. clang: warning: argument unused during compilation: '-march=armv6k' [-Wunused-command-line-argument] Since most assembler is non-conditionally assembled with one sub arch (modulo arch/arm/delay-loop.S which conditionally is assembled as armv4 based on CONFIG_ARCH_RPC, and arch/arm/mach-at91/pm-suspend.S which is conditionally assembled as armv7-a based on CONFIG_CPU_V7), prefer the .arch assembler directive. Add a few more instances found in compile testing as found by Arnd and Nathan.

soc: bcm: brcmstb: biuctrl: Avoid double of_node_put()

2022-09-15T21:30:29+00:00

Commit 9a073d4fbb18 ("soc: bcm: brcmstb: biuctrl: Add missing of_node_put()") added what was thought to be a missing of_node_put() but now causes a double of_node_put() to be called, once from setup_hifcpubiuctrl_regs() and another time from brcmstb_biuctrl_init(). Ensure that setup_hifcpubiuctrl_regs() is not calling of_node_put() since it is not obvious it does that on one of its parameters.
