The aspeed,sirq-polarity-sense property was a bit of a design mistake in that it ties Aspeed VUART SIRQ polarity to SCU register bits that aren't really inherently related to it; the first patch in this series deprecates it (though we hope to eventually remove it). The rest of the series adds two new properties, aspeed,lpc-io-reg and aspeed,lpc-interrupts. The latter allows describing the SIRQ polarity (along with the interrupt number) directly, providing a simpler replacement for aspeed,sirq-polarity-sense. Changes since v3 [2]: - renamed properties to match aspeed,ast2400-kcs-bmc Changes since v2 [0]: - expanded to also handle sirq number and lpc address in addition to sirq polarity - added default settings if DT properties not specified - refactored existing sysfs code slightly, adding range checks - cleaned up 'make dt_binding_check' warnings Changes since v1 [1]: - deprecate and retain aspeed,sirq-polarity-sense instead of removing it - drop e3c246d4i dts addition from this series [0] https://lore.kernel.org/openbmc/20210401005702.28271-1-zev@bewilderbeest.net/ [1] https://lore.kernel.org/openbmc/20210330002338.335-1-zev@bewilderbeest.net/ [2] https://lore.kernel.org/openbmc/20210402004716.15961-1-zev@bewilderbeest.net/ Zev Weiss (4): dt-bindings: serial: 8250: deprecate aspeed,sirq-polarity-sense drivers/tty/serial/8250: refactor sirq and lpc address setting code drivers/tty/serial/8250: add aspeed,lpc-io-reg and aspeed,lpc-interrupts DT properties dt-bindings: serial: 8250: add aspeed,lpc-io-reg and aspeed,lpc-interrupts .../devicetree/bindings/serial/8250.yaml | 28 +++++- drivers/tty/serial/8250/8250_aspeed_vuart.c | 95 +++++++++++++++---- 2 files changed, 103 insertions(+), 20 deletions(-)
