linux-ezx 2.6.21: update to r2011:
r2011: call send_readurb on bp_rdy signal from BP to keep BP communication active add asoc pxa2xx-ssp.c driver from asoc-v0.13rc3 r2010: * pxa-kbd.patch: Fix pxakbd bug: direct keys were not passed to userspace * a780-kbd.patch: Cleanup keycodes definition for a780, use unique keycodes so to avoid the double event problem occurring when the same keycode is used more than once. r2003: core: EZX subsystem ezx-phone.c file for each phone BP handshake code on a platform_driver (and another .patch) pm: fully functional suspend/resume (except for BP) reboot/poweroff new: a780 flip e680 lock switch bp: Kconfig entry to disable BP handshake (the watchdog dont start if we dont try to handshake) other: delete obsolete files r2002: * Implement vibrator handling for a780 using the leds class. r1999: * Port and readapt ezx-backlight patch. Let's use again the backlight class to handle lcd brightness. r1998: * Port leds patches for A780 and E680 (we still pollute ezx.c for now)
