[PATCH v2] serial: imx: warn user when using unsupported configuration

When using half-duplex mode (which disables receiver during txing) the RTS signal cannot be driven low during transmission. This seems to be a limitation of the i.MX UART IP: The RTS (CTS_B) signal is controlled by the receiver. When the receiver is disabled, the signal stays in UART logic idle

[PATCH] can: dev: increase bus-off message severity

bus-off is usually caused by hardware malfunction or configuration error (baud rate mismatch) and causes a complete loss of communication. Increase the "bus-off" message's severity from netdev_dbg to netdev_info to make it visible to the user. A can interface going into bus-off is similar in

[PATCH v6 6/9] PCI: dwc: Define maximum number of vectors

Adds a callback that defines the maximum number of vectors that can be use by the Root Complex. Since this is a parameter associated to each SoC IP setting, makes sense to be configurable and easily visible to future modifications. The designware IP supports a maximum of 256 vectors.

[PATCH v6 8/9] PCI: dwc: Small computation improvement

Replaces a simple division by 2 to a right shift rotation of 1 bit. Probably any recent and decent compiler does this kind of substitution in order to improve code performance. Nevertheless it's a coding good practice whenever there is a division / multiplication by multiple of 2 to replace it by
