[PATCH v2 1/3] bus: ti-sysc: Fix build warning for 64-bit build

[Tony Lindgren]

Fix "warning: cast from pointer to integer of different size" on 64-bit
builds.

Note that this is a cosmetic fix at this point as the driver is not yet
used for 64-bit systems.

[PATCH v2 2/3] bus: ti-sysc: Build driver for TI K3 SoCs

[Tony Lindgren]

Allow building ti-sysc also for K3 SoCs. This allows configuring the wkup
domain devices for SYSCONFIG register wake-up events in a generic way.

As this is an interconnect level driver, default to built-in on K3 SoCs
to probe the devices connected to the wkup domain like gpio, uart and
timers.

[PATCH v2 3/3] bus: ti-sysc: Configure uart quirks for k3 SoC

[Tony Lindgren]

Enable the uart quirks similar to the earlier SoCs. Let's assume we are
likely going to need a k3 specific quirk mask separate from the earlier
SoCs, so let's not start changing the revision register mask at this point.

Note that SYSC_QUIRK_LEGACY_IDLE will be needed until we can remove the
need for pm_runtime_irq_safe() from 8250_omap driver.

Thanks for the suggestion Nishanth,

Maybe something unrelated to this patch, but the driver has some minor
warning when built with W=1:

make W=1 ARCH=arm64 CROSS_COMPILE=aarch64-none-linux-gnu- drivers/bus/ti-sysc.o

drivers/bus/ti-sysc.c:156: warning: Function parameter or member 'sysconfig' not described in 'sysc'

Thanks yes it's unrelated, looks like sysconfig is not documented. I'll
send a patch for that separately.

Tony
