bus: ti-sysc: Handle swsup idle mode quirks

2019-04-05T22:10:36+00:00

In preparation of dropping interconnect target module platform data in
favor of devicetree based data, we must pass swsup idle quirks to the
platform data functions.

For now, let's only tag the UART modules with the SWSUP_SIDLE_ACT quirk.
The other modules will get tagged with swsup quirks as we drop the
platform data and test the changes.

bus: ti-sysc: Add quirk handling for external optional functional clock

2019-04-03T16:32:35+00:00

We cannot access mcpdm registers at all unless there is an optional pdmclk
configured. As this is currently only needed for mcpdm, let's check for
mcpdm in sysc_get_clocks(). If it turns out to be needed for other modules
too, we can add more flags to the quirks table for this.

bus: ti-sysc: Add support for early quirks based on register address

2019-04-03T16:32:35+00:00

At least mcpdm needs an optional external clock enabled to function and
this clock typically comes from the PMIC. We can detect mcpdm based on
the interconnect target module address and set a quirk flag early.

To do this, let's initialize the clocks a bit later and add a new
function for sysc_init_early_quirks(). Note that we cannot yet enable
the early quirks for mcpdm until the optional external clocks are
handled in the in the following patch.

bus: ti-sysc: Move rstctrl reset to happen later

2019-04-03T16:32:35+00:00

We can do the rsstctrl a bit later, but need to deassert rstctrl reset
before the clocks are enabled if asserted. Let's only init restctrl
in sysc_init_resets() and do the reset later on just before we enable
the device clocks.
