[PATCH AUTOSEL 5.10 2/4] gpio: mxc: Fix disabled interrupt wake-up support

[Sasha Levin]

From: Loic Poulain <loic.poulain@linaro.org>

[ Upstream commit 3093e6cca3ba7d47848068cb256c489675125181 ]

A disabled/masked interrupt marked as wakeup source must be re-enable
and unmasked in order to be able to wake-up the host. That can be done
by flaging the irqchip with IRQCHIP_ENABLE_WAKEUP_ON_SUSPEND.

Note: It 'sometimes' works without that change, but only thanks to the
lazy generic interrupt disabling (keeping interrupt unmasked).

[PATCH AUTOSEL 5.10 4/4] gpio: AMD8111 and TQMX86 require HAS_IOPORT_MAP

[Sasha Levin]

From: Johannes Berg <johannes.berg@intel.com>

[ Upstream commit c6414e1a2bd26b0071e2b9d6034621f705dfd4c0 ]

Both of these drivers use ioport_map(), so they need to
depend on HAS_IOPORT_MAP. Otherwise, they cannot be built
even with COMPILE_TEST on architectures without an ioport
implementation, such as ARCH=um.
