Subject: [PATCH 0/4] Platform/RaspberryPi: new GPIO and DT menu items
Date: Thu, 11 Nov 2021 00:57:37 -0600 [thread overview]
Message-ID: <20211111065742.8923-1-lintonrjeremy@gmail.com> (raw)
Its been reported that some kernel versions still need the XHCI reload
while others only work if the reload isn't present. Lets give the user
the ability to control that for DT systems.
Further, there is now an example persistent variable store implementation
that uses the on-board SPI flash rather than trying to rewrite the UEFI
firmware image on SD/etc late in the boot cycle. The problem is that
we now need to control the GPIO pin mux. This isn't a problem for
Linux as such, because it only messes with the pin mux under DT, but
windows has some drivers which export the GPIO devices using the
ACPI definition. Lets add a menu item to enable the GPIO and default
it to off on the RPi4 under the assumption that we can't fix a GPIO
pin mux war reliably and instead will simply revert to a mode that
fails to persist variables written while the OS is active if the
GPIO is enabled.
This set also cleans up the ACPI/DT visiblity of a couple
nearby menu items as well.
