Lad Prabhakar 87d084bcbf pinctrl: renesas: rzg2l: Reorganize variable configuration macro
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.
