The `PIN_CFG_VARIABLE` macro did not indicate the capabilities of a pin
but served as a flag indicating that the pins of a port have different
capabilities.
To better reflect its purpose, move the `PIN_CFG_VARIABLE` macro beside
`RZG2L_SINGLE_PIN` and rename it to `RZG2L_VARIABLE_CFG`. Additionally,
introduce new macros for packing variable port configurations:
- `RZG2L_GPIO_PORT_PACK_VARIABLE(n, a)`: Combines `RZG2L_VARIABLE_CFG`
with `RZG2L_GPIO_PORT_PACK` to handle variable pin configurations
for a packed port.
- `RZG2L_GPIO_PORT_SPARSE_PACK_VARIABLE(m, a)`: Combines
`RZG2L_VARIABLE_CFG` with `RZG2L_GPIO_PORT_SPARSE_PACK` to handle
variable pin configurations for a sparse port.
Due to the above change the configuration macros have been reorganized
as follows:
- Shift the bit positions of `PIN_CFG_NOGPIO_INT`, `PIN_CFG_NOD`,
`PIN_CFG_SMT`, `PIN_CFG_ELC`, and `PIN_CFG_IOLH_RZV2H` down by one
to accommodate the removal of `PIN_CFG_VARIABLE`.

Linux kernel
============
There are several guides for kernel developers and users. These guides can
be rendered in a number of formats, like HTML and PDF. Please read
Documentation/admin-guide/README.rst first.
In order to build the documentation, use ``make htmldocs`` or
``make pdfdocs``. The formatted documentation can also be read online at:
https://www.kernel.org/doc/html/latest/
There are various text files in the Documentation/ subdirectory,
several of them using the reStructuredText markup notation.
Please read the Documentation/process/changes.rst file, as it contains the
requirements for building and running the kernel, and information about
the problems which may result by upgrading your kernel.
