[PATCH 0/4] TI sysc driver updates for am335x and am437x

[PATCH 0/4] TI sysc driver updates for am335x and am437x

[Tony Lindgren]

Hi all,

Here are few updates for ti-sysc driver for am335x and am437x. I'll be
posting the related dts changes separately.

Based on testing with various devices, we can now also get rid of the
quirk flag for SYSC_QUIRK_RESOURCE_PROVIDER and make module names limited
to debug only except for few devices still using pm_runtime_irq_safe().

Regards,

Tony

[PATCH 1/4] bus: ti-sysc: Defer suspend as needed

[Tony Lindgren]

We don't care when we suspend but some our children do. In order to
avoid tagging various modules with SYSC_QUIRK_RESOURCE_PROVIDER, let's
do it automatically by tagging modules that are busy on suspend for
noirq suspend. This way we can just do module detection on define DEBUG.

Note that we still need to keep SYSC_QUIRK_LEGACY_IDLE flag around so
the our legacy single-child devices that set pm_runtime_irq_safe() can
manage the interconnect target module themselves.

[PATCH 2/4] bus: ti-sysc: Update revision masks to support am437x

[Tony Lindgren]

We need to detect few new devices to tag for noirq_suspend and
pm_runtime_irq_safe to avoid causing regressions compared to
legacy platform data booting.

Let's update i2c, gpio, uart and wdt revision masks to detect
them on am437x. Note that we can remove the second wdt entry
with the updated mask. Note that we also have some uarts with
a different revision register.

be available on am335x and dra7, and some just need updating the
