serial: 8250: Add Nuvoton NPCM UART

2018-04-08T12:27:37Z

commit f597fbce38d230af95384f4a04e0a13a1d0ad45d upstream. The Nuvoton UART is almost compatible with the 8250 driver when probed via the 8250_of driver, however it requires some extra configuration at startup.

2018-03-24T10:02:48Z

[ Upstream commit c1b9d4c75cd549e08bd0596d7f9dcc20f7f6e8fa ] The vendor name was "toppoly" but other panels and the vendor list have defined it as "tpo". So let's fix it in driver and bindings. We keep the old definition in parallel to stay compatible with potential older DTB setup. Signed-off-by: H.

dt-bindings: serial: Add common rs485 binding for RTS polarity

2018-03-19T08:09:51Z

[ Upstream commit 6abe9ea8a5a5904d935b8a482117a7fd9b25f09e ] rs485 allows for robust half-duplex serial communication. It is often implemented by attaching an rs485 transceiver to a UART. The UART's RTS line is wired to the transceiver's Transmit Enable pin and determines whether the transceiver is sending or receiving. Examples for such transceivers are Maxim MAX13451E and TI SN65HVD1781A: https://datasheets.maximintegrated.com/en/ds/MAX13450E-MAX13451E.pdf http://www.ti.com/lit/ds/symlink/sn65hvd1781a-q1.pdf In the devicetree, the transceiver itself is not represented, only the UART is. A few rs485-specific dt-bindings already exist and these go into the UART's device node. This commit adds a binding to set the RTS polarity. Most (if not all) transceivers require the Transmit Enable pin be driven high for sending, but in some cases boards may negate the pin and RTS must then be driven low. Consequently the polarity defaults to active high but can be inverted with the newly added "rs485-rts-active-low" binding. Document this binding in rs485.txt and in the two drivers fsl-imx-uart and fsl-lpuart that are about to be amended with support for it. Curiously, the omap_serial driver defaults to active low and already supports an "rs485-rts-active-high" binding to invert the polarity. This is left unchanged to retain compatibility, but the binding is herewith documented.

KVM: x86: fix backward migration with async_PF

2018-03-11T15:25:15Z

commit fe2a3027e74e40a3ece3a4c1e4e51403090a907a upstream. Guests on new hypersiors might set KVM_ASYNC_PF_DELIVERY_AS_PF_VMEXIT bit when enabling async_PF, but this bit is reserved on old hypervisors, which results in a failure upon migration. To avoid breaking different cases, we are checking for CPUID feature bit before enabling the feature and nothing else.
