Dautoidle.txt1 Binding for Texas Instruments autoidle clock.
3 Binding status: Unstable - ABI compatibility may be broken in the future
5 This binding uses the common clock binding[1]. It assumes a register mapped
6 clock which can be put to idle automatically by hardware based on the usage
7 and a configuration bit setting. Autoidle clock is never an individual
8 clock, it is always a derivative of some basic clock like a gate, divider,
9 or fixed-factor.

11 specific implementations of clock sources, clockevents and several likewise

2 * version sym53c8xx-1.7.3c
3 - Ensure LEDC bit in GPCNTL is cleared when reading the NVRAM.
4 Fix sent by Stig Telfer <stig@api-networks.com>.
5 - Backport from SYM-2 the work-around that allows to support
7 - Check that we received at least 8 bytes of INQUIRY response
9 - Define scsi_set_pci_device() as nil for kernel < 2.4.4.
