2019-07-12scripts/spelling.txt: add spelling fix for prohibitedChris Paterson1-1/+1
Misspelling 'prohibited' is quite common in the real world, although surprisingly not so much in the Linux Kernel. In addition to fixing the typo we may as well add it to the spelling checker. Also adding the present participle (prohibiting).

2019-06-28clk: Add Si5341/Si5340 driverMike Looijmans3-0/+1358
Adds a driver for the Si5341 and Si5340 chips. The driver does not fully support all features of these chips, but allows the chip to be used without any support from the "clockbuilder pro" software. If the chip is preprogrammed, that is, you bought one with some defaults burned in, or you programmed the NVM in some way, the driver will just take over the current settings and only change them on demand. Otherwise the input must be a fixed XTAL in its most basic configuration (no predividers, no feedback, etc.). The driver supports dynamic changes of multisynth, output dividers and enabling or powering down outputs and multisynths.

2019-06-25clk: Simplify debugfs printing and add a newlineStephen Boyd1-19/+15
The possible parent printing function duplicates a bunch of if conditions. Pull that into another function so we can print an extra character at the end, either a space or a newline. This way we can add the required newline that got lost here and also shorten the code.
