2015-05-11ARM: dts: dove: Add internal i2c multiplexer nodeSebastian Hesselbarth1-2/+38
This adds a i2c-mux-pinctrl node to dove.dtsi for the internal i2c mux found on Dove SoCs. Up to now, we had no board using any of the two additional i2c busses, so make sure the change does not break any existing boards. Therefore, we rename the i2c-controller node label to "i2c" and enable it by default. Also, the dedicated sub-bus (now "i2c0") is enabled by default. The two optional sub-busses require additional external pin-muxing, so disable them by default.

This add common pinctrl settings for pcie[01]_clkreq, spi1, i2c[23], and internal i2c mux. These settings have either one or two options only, so put them into the SoC dtsi instead of repeating them on board level.

2014-03-07ARM: dove: drop pinctrl PMU reg propertySebastian Hesselbarth1-2/+1
Marvell Dove's pinctrl does require some PMU regs for muxing PMU functions to MPP pins. Recently, a discussion started about consolidating Power Management Unit (PMU) into a single DT node. As we don't want anymore DT ABI in the way, drop the corresponding reg property from pinctrl node now. The driver will derive the registers from existing reg properties.

2014-01-16dt/bindings: remove device_type "network" referencesGrant Likely1-1/+0
device_type is deprecated and the kernel doesn't require it in most cases. The only exceptions for flat tree users are the "gianfar", "ucc_geth" and "ibm,emac" bindings, and arguably that requirement could be relaxed for ucc_geth and ibm,emac (that is a task for separate patches though). This patch removes references to device_type="network" from the binding documentation where possible and removes the properties from ARM and microblaze dts files. This patch does not modify the powerpc .dts files since there are a much larger number of them affected and I think the ucc_geth, ibm,emac and gianfar users should be addressed before clearing out the references to reduce the chance of breakage.

2014-01-16dt/bindings: Remove all references to device_type "ethernet-phy"Grant Likely1-1/+0
The device_type property is deprecated for the flattened device tree and the value "ethernet-phy" has never been defined as having a useful meaning. Neither the kernel nor u-boot depend on it. It should never have appeared in PHY bindings. This patch removes all references to "ethernet-phy" as a device_type value from the documentation and the .dts files. This patch was generated mechanically with the following command and then verified by looking at the diff. sed -i '/"ethernet-phy"/d' `git grep -l '"ethernet-phy"'` Signed-off-by: Grant Likely <grant.likely@linaro.org> Acked-by: Srinivas Kandagatla <srinivas.kandagatla@st.com> Cc: Rob Herring <rob.herring@calxeda.com> Cc: Pawel Moll <pawel.moll@arm.com> Cc: Mark Rutland <mark.rutland@arm.com> Cc: Ian Campbell <ijc+devicetree@hellion.org.uk> Cc: Kumar Gala <galak@codeaurora.org> Cc: Florian Fainelli <f.fainelli@gmail.com> Cc: Benjamin Herrenschmidt <benh@kernel.crashing.org>
