Light Hsieh 61754e3351 pinctrl: mediatek: Check gpio pin number and use binary search in mtk_hw_pin_field_lookup()
[ Upstream commit 3de7deefce693bb9783bca4cb42a81653ebec4e9 ]

1. Check if gpio pin number is in valid range to prevent from get invalid
   pointer 'desc' in the following code:
	desc = (const struct mtk_pin_desc *)&hw->soc->pins[gpio];

2. Improve  mtk_hw_pin_field_lookup()
2.1 Modify mtk_hw_pin_field_lookup() to use binary search for accelerating
     search.
2.2 Correct message after the following check fail:
    if (hw->soc->reg_cal && hw->soc->reg_cal[field].range) {
		rc = &hw->soc->reg_cal[field];
    The original message is:
    	"Not support field %d for pin %d (%s)\n"
    However, the check is on soc chip level, not on pin level yet.
    So the message is corrected as:
    	"Not support field %d for this soc\n"

README

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 Restructured Text 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.
