247414c6ad drivers/mtd and other MTD drivers: Remove mtd_procfsoperations since we can now get the same information from inode 2018-11-08 09:46:11 -06:00

936df1bcb5 Adds new OS internal functions nxsig_sleep() and nxsig_usleep. These differ from the standard sleep() and usleep() in that (1) they don't cause cancellation points, and (2) don't set the errno variable (if applicable). All calls to sleep() and usleep() changed to calls to nxsig_sleep() and nxsig_usleep(). 
Squashed commit of the following:

    Change all calls to usleep() in the OS proper to calls to nxsig_usleep()

    sched/signal:  Add a new OS internal function nxsig_usleep() that is functionally equivalent to usleep() but does not cause a cancellaption point and does not modify the errno variable.

    sched/signal:  Add a new OS internal function nxsig_sleep() that is functionally equivalent to sleep() but does not cause a cancellaption point.

af9590eef7 Extend the AT24Cxx MTD driver with support for -04,-08 and -16 parts. 
These parts utilize the same one-byte-address in the I2C protocol as the -02,
but requires different I2C addresses for different banks of the EEPROM.
