Hauke Mehrtens 6e80785267 MIPS: Lantiq: Fix check for return value of request_mem_region()
request_mem_region() returns a pointer and not an integer with an error
value. A check for "< 0" on a pointer will cause problems, replace it
with not null checks instead. This was found with sparse.

When the SoC starts up most of the devices should be deactivated by the
PMU, they should be activated when they get used by their drivers. Some
devices should not get deactivate at startup like the serial, register
them in a special way.

Hauke Mehrtens cab7b8363c MIPS: Lantiq: Add locking for PMU register and check status afterwards
The PMU register are accessed in a non atomic way and they could be
accessed by different threads simultaneously, which could cause
problems this patch adds locking around the PMU registers. In
addition we now also wait till the PMU is actually deactivated.

Rafał Miłecki d8cfb5037b MIPS: BCM47xx: Fetch board info directly in callback function
This drops another symbol dependency between setup.c and sprom.c which
will allow us to make SPROM code a separated module (and share it with
ARM).
Patch tested on Linksys WRT300N V1.

Rafał Miłecki daa7ce0251 MIPS: BCM47xx: Support on-SoC bus in SPROM reading function
To support (extract) SPROM on Broadcom ARM devices we should separate
SPROM code and make it a separated module. We won't want to export
bcm47xx_fill_sprom symbol so we should support SoC SPROM in the standard
fallback function and then modify ssb to use it.

This adds a basic implementation of clk_round_rate()
The clk_round_rate() function is called by multiple drivers and
subsystems now and the lantiq clk driver is supposed to export this,
but doesn't do so, this causes linking problems like this one:
ERROR: "clk_round_rate" [drivers/media/v4l2-core/videodev.ko] undefined!

Julia Lawall 972cfd5502 MIPS: pci-rt3883: drop unneeded of_node_get
for_each_child_of_node performs an of_node_get on each iteration, so no
of_node_get is needed on breaking out of the loop when the device_node
structure is saved in another variable.

A simplified semantic match that finds this problem is as follows
(http://coccinelle.lip6.fr):

// <smpl>
@@
expression root;
local idexpression child;
@@

 for_each_child_of_node(root, child) {
   ...
*  of_node_get(child)
   ...
   break;
 }
