From 397e7b515785cad6e10b29f3001fd80c3f519bb8 Mon Sep 17 00:00:00 2001 From: Daniel Tang Date: Thu, 5 Dec 2013 17:12:17 +1100 Subject: irqchip: Add support for TI-NSPIRE irqchip This patch adds support for the interrupt controllers found in some TI-Nspire models. FIQ support was taken out to simplify the driver code and may be added in later. Since Linux on this platform doesn't really use FIQs, this wasn't really that important in the first place.

This makes handling optional clocks simple, in that if the optional clock is not available, a NULL reference can be used in the place of a real clock, simplifying the clock consumer. Extend this concept to the phy consumer API. A NULL can be passed to the release calls, the phy_init() and phy_exit() calls, and phy_power_on() and phy_power_off() and a NOP is performed.

The console structure doesn't refer to any device in sysfs, only the tty the console is running on has. So we need to print out the tty names in 'active', not the console names.
