Merge tag 'tags/bcm2835-drivers-next-2019-03-12' into soc/fixes

2019-03-18T17:31:24+00:00

This pull request brings in a build fix for arm64 with bcm2835
enabled, and fixes the driver in the presence of -EPROBE_DEFER.

soc: bcm: bcm2835-pm: Fix error paths of initialization.

2019-03-04T23:33:14+00:00

The clock driver may probe after ours and so we need to pass the
-EPROBE_DEFER out.  Fix the other error path while we're here.

v2: Use dom->name instead of dom->gov as the flag for initialized
    domains, since we aren't setting up a governor.  Make sure to
    clear ->clk when no clk is present in the DT.

soc: bcm: bcm2835-pm: Fix PM_IMAGE_PERI power domain support.

2019-03-04T23:32:34+00:00

We don't have ASB master/slave regs for this domain, so just skip that
step.

soc: bcm: bcm2835-pm: Make local symbol static

Fixes the following sparse warning:

 symbol 'bcm2835_reset_ops' was not declared. Should it be static?

soc: bcm: Make PM driver default for BCM2835

2019-01-24T18:19:22+00:00

Since commit 52a4adbaebcc ("ARM: bcm283x: Switch V3D over to using the
PM driver instead of firmware.") VC4 on BCM2835 requires the power driver.

Otherwise the driver won't probe and HDMI output stays black:

soc: bcm: bcm2835-pm: Add support for power domains under a new binding.

2019-01-09T15:55:09+00:00

This provides a free software alternative to raspberrypi-power.c's
firmware calls to manage power domains.  It also exposes a reset line,
where previously the vc4 driver had to try to force power off the
domain in order to trigger a reset.

soc: bcm: brcmstb: Don't leak device tree node reference

2018-11-28T21:46:44+00:00

of_find_node_by_path() acquires a reference to the node returned by it
and that reference needs to be dropped by its caller. soc_is_brcmstb()
doesn't do that, so fix it.

Merge tag 'tags/bcm2835-drivers-next-2018-11-27' into drivers/next

2018-11-27T23:25:25+00:00

This pull request adds SPDX to BCM2835 drivers, and fixes some bugs in
the firmware driver (silently hanging if the VPU doesn't respond to a
mailbox transaction, and undersized buffers in the firmware property
transactions for tags that aren't used yet in the upstream).
