soc: bcm: brcmstb: biuctrl: Register writes require a barrier

2019-07-14T06:09:35Z

[ Upstream commit 6b23af0783a54efb348f0bd781b7850636023dbb ] The BIUCTRL register writes require that a data barrier be inserted after comitting the write to the register for the block to latch in the recently written values. Reads have no such requirement and are not changed. Fixes: 34642650e5bc ("soc: Move brcmstb to bcm/brcmstb") Signed-off-by: Florian Fainelli Signed-off-by: Sasha Levin

soc: brcmstb: Fix error path for unsupported CPUs

2019-07-14T06:09:35Z

[ Upstream commit 490cad5a3ad6ef0bfd3168a5063140b982f3b22a ] In case setup_hifcpubiuctrl_regs() returns an error, because of e.g: an unsupported CPU type, just catch that error and return instead of blindly continuing with the initialization. This fixes a NULL pointer de-reference with the code continuing without having a proper array of registers to use.

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

2019-03-04T23:33:14Z

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. Signed-off-by: Eric Anholt Fixes: 670c672608a1 ("soc: bcm: bcm2835-pm: Add support for power domains under a new binding.")

2019-01-24T18:19:22Z

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: vc4_v3d 20c00000.v3d: ignoring dependency for device, assuming no driver Signed-off-by: Stefan Wahren Reviewed-by: Eric Anholt

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.

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).
