max17042_get_status uses the core power_supply_am_i_supplied. That
function relies on DT properties to figure out the power supply
topology, and will error out without DT.
Fixes max17042 battery status being reported as "unknown".

Thank you Takashi.
I will also double confirm it with our Accessory BU guys about Ben's question
when I back to my office. And will let you know if there was any different
answer from them.

This patchset adds support for DISCONTIGMEM on 32-bit PowerPC. This is
required to properly support the Nintendo Wii's memory layout, in which
there are two blocks of RAM and MMIO in the middle.
Previously, this memory layout was handled by code that joins the two
RAM blocks into one, reserves the
of_node_to_nid and dump_numa_cpu_topology are declared inline in their
respective header files, if CONFIG_NUMA is not set. Thus it is only
valid to define these functions in numa.c if CONFIG_NUMA is set.
(numa.c, despite the name, isn't conditionalized on CONFIG_NUMA, but
CONFIG_NEED_MULTIPLE_NODES

The Nintendo Wii has a memory layout that places two chunks of RAM at
non-adjacent addresses, and MMIO between them. Currently, the allocation
of these MMIO areas is made possible by declaring the MMIO hole as
reserved memory and allowing reserved memory to be allocated (cf.
wii_memory_fixups).

When read_n_cells is compiled for PPC32, "result << 32" causes an
overshift, which GCC doesn't like. Fix this by using u64 instead of

You're right. The subsequent revision that was committed removed the
barrier. The commit is here:

The ISR reads interrupts-enable mask, but doesn't utilize it. Apply the
mask to the interrupt status and don't handle interrupts that MC driver
haven't asked for. Kernel would disable spurious MC IRQ and report the
error. This would happen only in a case of a very severe bug.

Currently we are enabling handling of interrupts specific to Tegra124+
which happen to overlap with previous generations. Let's specify
interrupts mask per SoC generation for consistency and in a preparation
of squashing of Tegra20 driver into the common one that will enable

Tegra's memory controller has a "memory hot reset" functionality that
