Subject: [RFC v8 net-next 02/16] pinctrl: microchip-sgpio: allow sgpio driver to be used as a module
Date: Sun,  8 May 2022 11:52:59 -0700	[thread overview]
Message-ID: <20220508185313.2222956-3-colin.foster@in-advantage.com> (raw)
In-Reply-To: <20220508185313.2222956-1-colin.foster@in-advantage.com>

As the commit message suggests, this simply adds the ability to select
SGPIO pinctrl as a module. This becomes more practical when the SGPIO
hardware exists on an external chip, controlled indirectly by I2C or SPI.
This commit enables that level of control.
