shame because (short of the product briefs) the
documents tend to be quite useful.
Let's replace them with known working versions of IA's Wayback Machine
links. That seems to be about the only way of getting a URL that's going
to work the next week.

If there's a mmc* alias in the device tree, take the device number from
it, so that we end up with a device name that matches the alias.

Hello,
This patch set modifies the OLPC battery driver so that it could eventually
be used on an Arm-based OLPC XO 1.75 machine.
Compared to the previous version, it addresses review comments for the
x86 platform parts from Thomas Gleixner. Details in individual patches'
change logs.

The XO-1 and XO-1.5 batteries apparently differ in an ability to report
ambient temperature.

The battery and the protocol are essentially the same as OLPC XO 1.5,
but the responses from the EC are LSB first.

This wouldn't work on the DT-based ARM platform. Let's read the EC version
directly from the EC driver instead.
This removes x86 specific bits that would prevent this driver from being
used with the EC of ARM-based OLPC XO 1.75.

is_broadcast_packet() expands to compare_ether_addr() which doesn't
exist since commit 7367d0b573d1 ("drivers/net: Convert uses of
compare_ether_addr to ether_addr_equal"). It turns out it's actually not
used.

s are and Marvel was unhelpful
when asked for documentation. Aside from the SP bit, there are probably
priority bits.
Leaving the unknown bits as the firmware set them up seems to be a wiser
course of action compared to just turning them off.
