Changes from v2 -> v3;
- Schema fixes:
- add "clocks" and "clock-names" properties, comment legacy use of
"clock-frequency".
- Driver fixes:
- get clock rate as a clock consumer, if available
Changes from v1 -> v2:
- Schema fixes:
- Fix schema to now pass "make DT_CHECKER_FLAGS=-m dt_binding_check"
- Rename unprefixed "transceiver" to "ni,serial-port-mode" with a
description. Describing this as a "mode" rather than a "transceiver"
seems more semantically correct in comparison to other DTs; other
schemas with a "transceiver" property (isp1301, lpc32xx-udc) have
phandle values, which is not the case here.
- Driver fixes:
- replace C99 integer types with kernel types
- reverse christmas tree
- stuff PMR mode/cap masks into locals to avoid repetition
- wrap ACPI match table in #ifdef CONFIG_ACPI to avoid build error on
non-ACPI platforms
- NI 16550s are only on x86 and Zynq-7000 NI devices, so constrain the
Kconfig "depends" to only present it as an option to users on those
architectures, to prevent it from being needlessly built on platforms
that would not possibly have them.
- document module name
- add check for "ni,serial-port-mode" property; "transceiver" remains
for sake of compatibility with _DSD ACPI objects for NI controller
BIOSes currently in-field (but also DSD-properties-rules.rst says
that _DSD properties don't have to be identical to DT bindings.)
