Reduce magic numbers and improve code readability by implementing and utilizing named register data structures. The 104-IDI-48 device features an Intel 8255 compatible GPIO interface, so the i8255 GPIO module is selected and utilized as well.

2022-07-20gpio: i8255: Introduce the Intel 8255 interface library moduleWilliam Breathitt Gray
Exposes consumer library functions providing support for interfaces compatible with the venerable Intel 8255 Programmable Peripheral Interface (PPI). The Intel 8255 PPI first appeared in the early 1970s, initially for the Intel 8080 and later appearing in the original IBM-PC. The popularity of the original Intel 8255 chip led to many subsequent variants and clones of the interface in various chips and integrated circuits. Although still popular, interfaces compatible with the Intel 8255 PPI are nowdays typically found embedded in larger VLSI processing chips and FPGA components rather than as discrete ICs. A CONFIG_GPIO_I8255 Kconfig option is introduced by this patch. Modules wanting access to these i8255 library functions should select this Kconfig option, and import the I8255 symbol namespace.

2022-07-19gpiolib: cdev: consolidate edge detector configuration flagsKent Gibson
Combine the polarity_change flag, struct line eflags, and hte enable flag into a single flag variable. The combination of these flags describes the configuration state of the edge detector, so formalize and clarify that by combining them into a single variable, edflags, in struct line. The edflags is a subset of the GPIO_V2_LINE_FLAGsb relevant to the edge detector, and is also a superset of the eflags it replaces. The eflags name is still used to describe the subset of edflags corresponding to the rising/falling edge flags where edflags is masked down to that subset. This consolidation reduces the number of variables being passed, simplifies state comparisons, and provides a more extensible foundation should additional edge sources be integrated in the future.

2022-07-19gpio: gpiolib-of: Fix refcount bugs in of_mm_gpiochip_add_data()Liang He
We should use of_node_get() when a new reference of device_node is created. It is noted that the old reference stored in 'mm_gc->gc.of_node' should also be decreased. This patch is based on the fact that there is a call site in function 'qe_add_gpiochips()' of src file 'drivers\soc\fsl\qe\gpio.c'. In this function, of_mm_gpiochip_add_data() is contained in an iteration of for_each_compatible_node() which will automatically increase and decrease the refcount. So we need additional of_node_get() for the reference escape in of_mm_gpiochip_add_data().

2022-07-16random: cap jitter samples per bit to factor of HZJason A. Donenfeld
Currently the jitter mechanism will require two timer ticks per iteration, and it requires N iterations per bit. This N is determined with a small measurement, and if it's too big, it won't waste time with jitter entropy because it'd take too long or not have sufficient entropy anyway. With the current max N of 32, there are large timeouts on systems with a small CONFIG_HZ. Rather than set that maximum to 32, instead choose a factor of CONFIG_HZ. In this case, 1/30 seems to yield sane values for different configurations of CONFIG_HZ.
