AM4372 SoC has 2 DCAN modules. Add compatible id and raminit driver data for it. The driver data is same as AM3352 but this gives us flexibility to add AM4372 specific quirks if required later. Signed-off-by: Roger Quadros <rogerq@ti.com> Signed-off-by: Marc Kleine-Budde <mkl@pengutronix.de>

Bosch C_CAN/D_CAN controller Device Tree Bindings
|
|
-------------------------------------------------
|
|
|
|
Required properties:
|
|
- compatible : Should be "bosch,c_can" for C_CAN controllers and
|
|
"bosch,d_can" for D_CAN controllers.
|
|
Can be "ti,dra7-d_can", "ti,am3352-d_can" or
|
|
"ti,am4372-d_can".
|
|
- reg : physical base address and size of the C_CAN/D_CAN
|
|
registers map
|
|
- interrupts : property with a value describing the interrupt
|
|
number
|
|
|
|
Optional properties:
|
|
- ti,hwmods : Must be "d_can<n>" or "c_can<n>", n being the
|
|
instance number
|
|
- syscon-raminit : Handle to system control region that contains the
|
|
RAMINIT register, register offset to the RAMINIT
|
|
register and the CAN instance number (0 offset).
|
|
|
|
Note: "ti,hwmods" field is used to fetch the base address and irq
|
|
resources from TI, omap hwmod data base during device registration.
|
|
Future plan is to migrate hwmod data base contents into device tree
|
|
blob so that, all the required data will be used from device tree dts
|
|
file.
|
|
|
|
Example:
|
|
|
|
Step1: SoC common .dtsi file
|
|
|
|
dcan1: d_can@481d0000 {
|
|
compatible = "bosch,d_can";
|
|
reg = <0x481d0000 0x2000>;
|
|
interrupts = <55>;
|
|
interrupt-parent = <&intc>;
|
|
status = "disabled";
|
|
};
|
|
|
|
(or)
|
|
|
|
dcan1: d_can@481d0000 {
|
|
compatible = "bosch,d_can";
|
|
ti,hwmods = "d_can1";
|
|
reg = <0x481d0000 0x2000>;
|
|
interrupts = <55>;
|
|
interrupt-parent = <&intc>;
|
|
status = "disabled";
|
|
};
|
|
|
|
Step 2: board specific .dts file
|
|
|
|
&dcan1 {
|
|
status = "okay";
|
|
};
