Tested on a JZ4740 system (ARCH=mips make qi_lb60_defconfig), this saves about 14 KiB, by allowing the compiler to garbage-collect all the functions and tables that correspond to SoCs that were disabled in the config. Signed-off-by:

IF_ENABLED(CONFIG_FOO, ptr) evaluates to (ptr) if CONFIG_FOO is set to 'y' or 'm', NULL otherwise. The (ptr) argument must be a pointer. The IF_ENABLED() macro can be very useful to help GCC drop dead code. For instance, consider the following: #ifdef CONFIG_FOO_SUSPEND static int foo_suspend(struct device *dev) { ... } #endif static struct pm_ops foo_ops = { #ifdef CONFIG_FOO_SUSPEND .suspend = foo_suspend, #endif }; While this works, the foo_suspend() macro is compiled conditionally, only when CONFIG_FOO_SUSPEND is set. This is problematic, as there could be a build bug in this function, we wouldn't have a way to know unless the config option is set. An alternative is to declare foo_suspend() always, but mark it as maybe unused: static int __maybe_unused foo_suspend(struct device *dev) { ... } static struct pm_ops foo_ops = { #ifdef CONFIG_FOO_SUSPEND .suspend = foo_suspend, #endif }; Again, this works, but the __maybe_unused attribute is required to instruct the compiler that the function may not be referenced anywhere, and is safe to remove without making a fuss about it. This makes the programmer responsible for tagging the functions that can be garbage-collected. With this patch, it is now possible to write the following: static int foo_suspend(struct device *dev) { ... } static struct pm_ops foo_ops = { .suspend = IF_ENABLED(CONFIG_FOO_SUSPEND, foo_suspend), }; The foo_suspend() function will now be automatically dropped by the compiler, and it does not require any specific attribute.

The V3U SoC has several unlock registers, one per register group. They reside at offset zero in each 0x200 bytes-sized block. To avoid adding yet another table to the PFC implementation, this patch adds the option to specify an address mask instead of the fixed address in sh_pfc_soc_info::unlock_reg. Signed-off-by:

When DEBUG is defined (e.g. if CONFIG_DEBUG_PINCTRL=y), the Renesas pin control driver runs sanity checks against the pin control tables. This may cause lots of output on the console, and can be annoying in ARM multi-platform kernels. Fix this by only running the checks when running on SuperH, or on a DT platform supported by the Renesas pin controller driver. Suggested-by:

As there is an RSB controller in the H6 SoC, there should be some pin configuration for it. While no such configuration is documented, the "s_i2c" pins are suspiciously on the "alternate" function 3, with no primary function 2 given. This suggests the primary function for these pins is actually RSB, and that is indeed the case. Add the "s_rsb" pin functions so the RSB controller can be used. Signed-off-by:

When this bindings where applied there weren't already reviewed and some old hacks was being used to properly pass the schemas checks. This commits fix them up: - Instead of using 'if-then' clause use '-pins$'. - 'groups' and 'function' are included inside a new '^(.*-)?pinmux$' node. - compatible string is not an 'enum' but a 'const'. - 'pinctrl-0' and 'pinctrl-names' removed since they are used in consumer nodes.
