bus: mvebu-mbus: use %pa to print phys_addr_t

2016-03-30T09:36:01Z

A recent change to the mbus driver added a warning printk that prints a phys_addr_t using the %x format string, which fails in case we build with 64-bit phys_addr_t: drivers/bus/mvebu-mbus.c: In function 'mvebu_mbus_get_dram_win_info': drivers/bus/mvebu-mbus.c:975:9: error: format '%x' expects argument of type 'unsigned int', but argument 2 has type 'phys_addr_t {aka long long unsigned int}' [-Werror=format=] This uses the special %pa format string instead, so we always print the correct type.

Pull arm[64] perf updates from Will Deacon: "I have another mixed bag of ARM-related perf patches here. It's about 25% CPU and 75% interconnect, but with drivers/bus/ languishing without an obvious maintainer or tree, Olof and I agreed to keep all of these PMU patches together. I suspect a whole load of code from drivers/bus/arm-* can be moved under drivers/perf/, so that's on the radar for the future.

bus: mvebu-mbus: provide api for obtaining IO and DRAM window information

2016-03-14T16:19:46Z

This commit enables finding appropriate mbus window and obtaining its target id and attribute for given physical address in two separate routines, both for IO and DRAM windows. This functionality is needed for Armada XP/38x Network Controller's Buffer Manager and PnC configuration.

bus: imx-weim: Take the 'status' property value into account

2016-03-13T01:07:39Z

Currently we have an incorrect behaviour when multiple devices are present under the weim node. For example: &weim { ... status = "okay"; sram@0,0 { ... status = "okay"; }; mram@0,0 { ... status = "disabled"; }; }; In this case only the 'sram' device should be probed and not 'mram'. However what happens currently is that the status variable is ignored, causing the 'sram' device to be disabled and 'mram' to be enabled. Change the weim_parse_dt() function to use for_each_available_child_of_node()so that the devices marked with 'status = disabled' are not probed.
