STiH415/6 SoC support is being removed from the kernel. This patch updates the sti dt softreset bindings and removes references to these obsolete platforms. Signed-off-by: Peter Griffin <peter.griffin@linaro.org> Signed-off-by: Philipp Zabel <p.zabel@pengutronix.de>

STMicroelectronics STi family Sysconfig Peripheral SoftReset Controller
|
|
=============================================================================
|
|
|
|
This binding describes a reset controller device that is used to enable and
|
|
disable on-chip peripheral controllers such as USB and SATA, using
|
|
"softreset" control bits found in the STi family SoC system configuration
|
|
registers.
|
|
|
|
The actual action taken when softreset is asserted is hardware dependent.
|
|
However, when asserted it may not be possible to access the hardware's
|
|
registers and after an assert/deassert sequence the hardware's previous state
|
|
may no longer be valid.
|
|
|
|
Please refer to reset.txt in this directory for common reset
|
|
controller binding usage.
|
|
|
|
Required properties:
|
|
- compatible: Should be st,stih407-softreset";
|
|
- #reset-cells: 1, see below
|
|
|
|
example:
|
|
|
|
softreset: softreset-controller {
|
|
#reset-cells = <1>;
|
|
compatible = "st,stih407-softreset";
|
|
};
|
|
|
|
|
|
Specifying softreset control of devices
|
|
=======================================
|
|
|
|
Device nodes should specify the reset channel required in their "resets"
|
|
property, containing a phandle to the softreset device node and an
|
|
index specifying which channel to use, as described in reset.txt
|
|
|
|
example:
|
|
|
|
ethernet0{
|
|
resets = <&softreset STIH415_ETH0_SOFTRESET>;
|
|
};
|
|
|
|
