Binding for Texas Instruments gate clock.
|
||||
|
||||
Binding status: Unstable - ABI compatibility may be broken in the future
|
||||
|
||||
This binding uses the common clock binding[1]. This clock is
|
||||
quite much similar to the basic gate-clock [2], however,
|
||||
it supports a number of additional features. If no register
|
||||
is provided for this clock, the code assumes that a clockdomain
|
||||
will be controlled instead and the corresponding hw-ops for
|
||||
that is used.

|

|
||||
Required properties:
|
||||
- compatible : shall be one of:
|
||||
"ti,gate-clock" - basic gate clock
|
||||
"ti,wait-gate-clock" - gate clock which waits until clock is active before
|
||||
returning from clk_enable()
|
||||
"ti,dss-gate-clock" - gate clock with DSS specific hardware handling
|
||||
"ti,am35xx-gate-clock" - gate clock with AM35xx specific hardware handling
|
||||
"ti,clkdm-gate-clock" - clockdomain gate clock, which derives its functional
|
||||
clock directly from a clockdomain, see [3] how
|
||||
to map clockdomains properly
|
||||
"ti,hsdiv-gate-clock" - gate clock with OMAP36xx specific hardware handling,
|
||||
required for a hardware errata
|
||||
"ti,composite-gate-clock" - composite gate clock, to be part of composite
|
||||
clock
|
||||
"ti,composite-no-wait-gate-clock" - composite gate clock that does not wait
|
||||
for clock to be active before returning
|
||||
from clk_enable()
|
||||
- #clock-cells : from common clock binding; shall be set to 0
|
||||
- clocks : link to phandle of parent clock
|
||||
- reg : offset for register controlling adjustable gate, not needed for
|
||||
ti,clkdm-gate-clock type
|
||||
|
||||
Optional properties:
|
||||
- ti,bit-shift : bit shift for programming the clock gate, invalid for
|
||||
ti,clkdm-gate-clock type
|
||||
- ti,set-bit-to-disable : inverts default gate programming. Setting the bit
|
||||
gates the clock and clearing the bit ungates the clock.
