* ARM: mvebu: adjust ethernet aliases according to U-Boot requirements for A38xMarcin Wojtas2014-11-221-3/+3
| | | | | | | | | | | | | | | | | | In order to update MAC address entries in the ethernet nodes in Device Tree both mainline U-Boot and Barebox bootloaders accept the same format of aliases, which is 'ethernetX', where X stands for an interface number. Other platforms in the mainline Linux, that comprise ethernet references in '/aliases' node (like various flavours of imx or sunXi), follow the naming scheme described above. This commit ajusts ethernet aliases of Marvell Armada 38x SoC to be properly recognized by bootloaders' MAC address fixup routines.

| * ARM: mvebu: add CA9 MPcore SoC Controller nodeGregory CLEMENT2014-07-161-0/+5
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The CA9 MPcore SoC Control block is a set of registers that allows to configure certain internal aspects of the core blocks of the SoC (Cortex-A9, L2 cache controller, etc.). In most cases, the default values are fine so they aren't many reasons to touch those registers, but there is one exception: to support cpuidle on Armada 38x, we need to modify the value of the CA9 MPcore Reset Control register. Therefore, this commit adds a new Device Tree binding for this hardware block, and uses this new binding for the Armada 38x Device Tree file.

|/ | | | | | | | | | | | | | | | | wildcard Wildcards in compatible strings should be avoid. "marvell,armada38x" was recently introduced but was not yet used. The armada 385 SoC is a superset of the armada 380 SoC (with more CPUs and more PCIe slots). So this patch replaces the use of "marvell,armada38x" by the "marvell,armada380" string.

| * ARM: mvebu: use clocks property for serial portsThomas Petazzoni2014-04-261-0/+2
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Back when the Armada 370 and Armada XP initial support was introduced, the only way to pass the clock frequency to the of_serial driver was through a clock-frequency Device Tree property. Thanks to 0bbeb3c3e84bc963d1c66661e082d207023b0e5c ('of serial port driver - add clk_get_rate() support'), it is possible to use the standard 'clocks' DT property to reference the clock used for a particular UART controller. This clock is then used by the of_serial driver to retrieve the clock rate. This commit modifies the SoC-level Device Tree files of Armada 370, Armada XP, Armada 375 and Armada 38x to use this possibility. Since there is no gatable clock for the UART controllers, we simply reference the TCLK, which is the main SoC clock for the peripherals.
