[PATCH v4 01/11] mfd: add atmel-hlcdc driver

The HLCDC IP available on some Atmel SoCs (i.e. at91sam9n12, at91sam9x5 family or sama5d3 family) exposes 2 subdevices: - a display controller (controlled by a DRM driver) - a PWM chip The MFD device provides a regmap and several clocks (those connected to this hardware block) to its subdevices.

Hi Felipe, Sorry for the delay in replying. I've been trying to get to the root cause of this problem so I could reply which took longer than I had hoped. The problem manifested itself as a hang on register read/write access if dwc3-st probed before the usb3 phy. Even though dwc3 core would bai

[PATCH v2 2/2] printk: improve some commentary; tidy up

Add some comments to explain how the log flags are used to control how records get formatted. Also add and refine some comments in vprintk_emit(). Now that we're done fixing up log record flags, simplify how they're used in computing some local variable values in msg_print_text(). Use a local va

[PATCH v2 0/2] printk: more log flag simplification

This series eliminates the LOG_CONT entirely from the printk/log code. It builds on another series, posted earlier today: http://www.spinics.net/lists/kernel/msg1791665.html This series was originally longer, but in review I was reminded that some of the simplifications I had done were not vali

[PATCH v2 1/2] printk: kill LOG_CONT

The LOG_CONT and LOG_NEWLINE flags are mutually exclusive, i.e., the presence of LOG_NEWLINE implies the absense of LOG_CONT, and vice-versa. As a result, wherever LOG_CONT is used, we can equivalently substitute !LOG_NEWLINE; and we can use LOG_NEWLINE wherever !LOG_CONT is used. Switch to using
