In these SoCs it's possible to control LEDs both as GPIOs or by hardware.
However, on some devices there are Serial LEDs (LEDs connected to a 74x164
controller), which can either be controlled by software (exporting the 74x164
-as spi-gpio. See Documentation/devicetree/bindings/gpio/gpio-74x164.txt), or

+as spi-gpio. See Documentation/devicetree/bindings/gpio/fairchild,74hc595.yaml),
+or by hardware using this driver.
Some of these Serial LEDs are hardware controlled (e.g. ethernet LEDs) and
exporting the 74x164 as spi-gpio prevents those LEDs to be hardware
controlled, so the only chance to keep them working is by using this driver.
This controller is present on BCM6358 and BCM6368.

+------
+When ptracing system calls (PTRACE_SYSCALL), the pt_regs.trap value contains
+the system call type that can be used to distinguish between sc and scv 0
+system calls, and the different register conventions can be accounted for.
+
+If the value of (pt_regs.trap & 0xfff0) is 0xc00 then the system call was
+performed with the sc instruction, if it is 0x3000 then the system call was
+performed with the scv 0 instruction.
