[PATCH v3 1/5] ARM: dts: pxa: add pwri2c to pxa device-tree

[PATCH v3 1/5] ARM: dts: pxa: add pwri2c to pxa device-tree

[Robert Jarzmik]

pxa27x variant has 2 I2C busses on the SoC :
 - the casual I2C
 - the power I2C, normally driving power regulators, and capable of
 receiving orders on core frequency modifications

Add the missing pwri2c to pxa27x description.

Since v2: as Dmitry pointed out, no pwri2c on pxa25x, only pxa27x

[PATCH v3 2/5] ARM: dts: pxa: add clocks

[Robert Jarzmik]

Add clocks to the IPs already described in the pxa device-tree
files. There are more clocks in the clock tree than IPs described in the
current pxa device-tree.

This patch ensures that :
 - the current description is correct
 - the clocks are actually claimed, so that clock framework doesn't
   disable them automatically (unused clocks shutdown)

Good to know, but not for this patch.

The naming is coming from pxa2xx.dtsi. And you're very welcome to post a patch
to fix that ;)

Good to know, but not for this patch.

The naming is coming from pxa2xx.dtsi. And you're very welcome to post a patch
to fix that ;)

Cheers.

    Ah, I was wondering why the node descriptions included only one prop.

[PATCH v3 2/5] ARM: dts: pxa: add clocks

[Robert Jarzmik]

After another thought about your "one line" node, I think this can be even
improved, so that :
 - uart clocks are put into pxa2xx.dtsi instead of pxa27x.dtsi
 - replace all pxa2xx_clks by clks
 - let pxa27x.dtsi, pxa3xx.dtsi declare the clks label

This way we'll have :
 - pxa2xx.dtsi
		ffuart: uart at 40100000 {
                        compatible = ...
                        ...
			clocks = <&clks CLK_FFUART>;
		};
 - pxa27x.dtsi
                clks: pxa2xx_clks at 41300004 {
                        compatible = "marvell,pxa270-clocks";
                        #clock-cells = <1>;
                        status = "okay";
                };
 - pxa3xx.dtsi
                clks: pxa3xx_clks at 41300004 {
                        compatible = "marvell,pxa300-clocks";
                        #clock-cells = <1>;
                        status = "okay";
                };
