Re: [linux-sunxi] Re: i2s audio codec support for sun7i
Hi Puneet Have a look into some on some of the drivers handle the regulators power. rtl8723bs sdio wifi for example.

At the time of the submission v6 was already the patchset without the patches from v5 already applied and v6 already contains all the ACKs I have collected (i.e. the input/misc driver has been already ack-ed by Dmitry, yet it seems not merged). So what exactly do you want me to resubmit? The whole v6 on top of v3.16-rc1+? -- Carlo Caione -- You received this message because you are subscribed to the Google Groups linux-sunxi group.

Yes Yassin, but not get any idea. if you see this link, here they are passing via ldo. http://e2e.ti.com/support/arm/sitara_arm/f/791/p/345940/1224371.aspx * Regulators */ AVDD-supply = ldo4_reg; IOVDD-supply = ldo4_reg; DRVDD-supply = ldo4_reg; DVDD-supply = ldo1_reg; HPVDD-supply = ldo4_reg; SPRVDD-supply = ldo4_reg; SPLVDD-supply = ldo4_reg; Is it possible in sunxi?.

+Device-Tree bindings for SUNXI IR controller found in sunXi SoC family

+Required properties:
+- compatible : should be allwinner,sun7i-a20-ir;
+- clocks : list of clock specifiers, corresponding to
+ entries in clock-names property;
+- clock-names : should contain apb and ir entries;
+- interrupts : should contain IR IRQ number;
+- reg : should contain IO map address for IR.
+
+Optional properties:
+- linux,rc-map-name : Remote control map name.

+Example:
