2021-01-27bus: fsl-mc: add fsl-mc userspace supportIoana Ciornei
Adding userspace support for the MC (Management Complex) means exporting an ioctl capable device file representing the root resource container. This new functionality in the fsl-mc bus driver intends to provide userspace applications an interface to interact with the MC firmware. Commands that are composed in userspace are sent to the MC firmware through the FSL_MC_SEND_MC_COMMAND ioctl. By default the implicit MC I/O portal is used for this operation, but if the implicit one is busy, a dynamic portal is allocated and then freed upon execution. The command received through the ioctl interface is checked against a known whitelist of accepted MC commands. Commands that attempt a change in hardware configuration will need CAP_NET_ADMIN, while commands used in debugging do not need it.

2021-01-27misc: pti: Remove driver for deprecated platformAndy Shevchenko
Intel Moorestown and Medfield are quite old Intel Atom based 32-bit platforms, which were in limited use in some Android phones, tablets and consumer electronics more than eight years ago. There are no bugs or problems ever reported outside from Intel for breaking any of that platforms for years. It seems no real users exists who run more or less fresh kernel on it. The commit 05f4434bc130 ("ASoC: Intel: remove mfld_machine") also in align with this theory. Due to above and to reduce a burden of supporting outdated drivers we remove the support of outdated platforms completely.

2021-01-27speakup: Reference synth from tty and tty from synthSamuel Thibault
We do not actually need speakup_tty and spk_ttyio_synth global variables, the synth can store the pointer to the tty, and the tty ldisc_data can store the pointer to the synth. Along the way, we can clench the initialization of the synth and the creation of the tty, so that tty is never NULL. Even if the device disappears (e.g. USB unplug), the tty structure will still be there, and we automatically stop speakup in the spk_ttyio_out error handler but keep tty until the user cleans things up. As a result, this simplifies locking a lot.

2021-01-25misc: bcm-vk: add open/releaseScott Branden
Add open/release to replace private data with context for other methods to use. Reason for the context is because it is allowed for multiple sessions to open sysfs. For each file open, when upper layer queries the response, only those that are tied to a specified open should be returned.
