soc: bcm: raspberrypi-power: Release firmware handle on unbind

2021-03-22T16:59:51+00:00

Use devm_rpi_firmware_get() so as to make sure we release RPi's firmware
interface when unbinding the device.

soc: bcm: brcmstb: Remove soc_is_brcmstb()

2021-01-27T17:36:41+00:00

We have no in tree or out of tree users of this function, remove it and
the header providing its prototype.

soc: bcm: add PM driver for Broadcom's PMB

2021-01-13T04:45:57+00:00

PMB originally comes from BCM63138 but can be also found on many other
chipsets (e.g. BCM4908). It's needed to power on and off SoC blocks like
PCIe, SATA, USB.

soc: bcm: brcmstb: pm: pm-arm: Provide prototype for brcmstb_pm_s3_finish()

2020-11-04T03:25:04+00:00

brcmstb_pm_s3_finish() cannot be made static because it is referenced
from brcmstb_pm_s3(), so let's provide a prototype for it instead.

Fixes the following W=1 kernel build warning(s):

 drivers/soc/bcm/brcmstb/pm/pm-arm.c:395:14: warning: no previous prototype for ‘brcmstb_pm_s3_finish’ [-Wmissing-prototypes]

soc: bcm: brcmstb: biuctrl: Change RAC data line prefetching after 4 consecutive lines

2020-09-06T19:43:02+00:00

Change the RACPREFDATA(x) setting to prefetch the next 256-byte line
after 4 consecutive lines have been used, instead of after 2 consecutive
lines. This does improve the synthetic memcpy benchmark by an additional
+0.5% on top of the previous change for Cortex-A72 CPUs.

soc: bcm: brcmstb: biuctrl: Change RAC prefetch distance from +/-1 to +/- 2

2020-09-04T20:48:49+00:00

Change the RAC prefetch distance from +/- 1 to +/- 2 for Cortex-A72 CPUs
since this provides an average of a 3.8% performance increase for
synthetic memcpy benchmarks.
