Subject: [PATCH 00/10] RPi mailbox support
Date: Sat, 19 Oct 2013 14:18:41 +0200 [thread overview]
Message-ID: <1382185130-28995-1-git-send-email-a.heider@gmail.com> (raw)
This adds a bcm2835 mailbox driver for the RPi to talk to the on-SoC
VideoCore. See [1] for a description.
This patchset uses it to get two properties, the eMMC clock and the
memory size.
The RPi backend needs to use this driver early on, namely before the
MMU setup. We also want to use the driver in the future after the MMU setup,
like setting up simplefb for the kernel. Patch 1 and 2 lay the groundwork
for that.
The mailbox driver also needs to handle timouts, so patch 5 and 6 are
making the clocksource accessible earlier.
Patch 7 is the driver itself, providing a helper macro for users based on
a new common macro from patch 3.
Patch 8 and 9 switch the bc2835_mci driver from a local mailbox
implementation to the new driver.
Patch 10 uses the driver to get the proper memory size.
Patch 4 is just a cleanup.
Thanks,
Andre
