soc: bcm: raspberrypi-power: Fix use of __packed

2018-04-16T22:15:23+00:00

Commit a09cd356586d ("ARM: bcm2835: add rpi power domain driver") attempted to annotate the structure rpi_power_domain_packet with __packed but introduced a typo and made it named __packet instead. Just drop the annotation since the structure is naturally aligned already. Fixes: a09cd356586d ("ARM: bcm2835: add rpi power domain driver") Signed-off-by: Florian Fainelli

soc: bcm: brcmstb: Be multi-platform compatible

2018-01-15T14:47:07+00:00

We were making a bunch of wrong assumptions that turned out to blow out on non-Broadcom STB platforms: - we would return -ENODEV from brcmstb_soc_device_early_init() if we could not find the sun_top_ctrl device node, this is not an error in the context of a multi-platform kernel - we would still try to register the Broadcom STB SoC device, even if we are not running on such a platform While at it, also fix the sun_top_ctrl device_node leaks while we change the flow of brcmstb_soc_device_init() and brcmstb_soc_device_early_init().

soc: brcmstb: biuctrl: exit without warning on non brcmstb platforms

2018-01-15T14:46:17+00:00

Currently if this driver is included, we get the following warning on any platforms irrespective of whether it's brcmstb platform or not. " brcmstb: biuctrl: missing BIU control node brcmstb: biuctrl: MCP: Unable to disable write pairing! " This patch allows to exit early without any warning messages on non brcmstb platforms as it's meaningless for them.

soc: brcmstb: Only register SoC device on STB platforms

2018-01-12T01:01:22+00:00

After moving the SoC device initialization to an early initcall in commit f780429adfbc ("soc: brcmstb: biuctrl: Move to early_initcall"), the Broadcom STB SoC device is registered on all platforms if support for the device is enabled in the kernel configuration. This causes an additional SoC device to appear on platforms that already register a native one. In case of Tegra the STB SoC device is registered as soc0 (with totally meaningless content in the sysfs attributes) and causes various scripts and programs to fail because they don't know how to parse that data. To fix this, duplicate the check from brcmstb_soc_device_early_init() that already prevents the code from doing anything nonsensical on non- STB platforms.

soc: brcmstb: biuctrl: Move to early_initcall

2017-12-21T01:37:44+00:00

Being called during early_initcall() is early enough that it occurs before SMP initialization, which is all we care about for the Bus Interface Unit configuration. This solves lack of BIU initialization on ARM64 platforms where we do not have an anchor where to put the BIU initialization (since there are no machine descriptors). Signed-off-by: Florian Fainelli

soc: brcmstb: Split initialization

2017-12-21T01:37:43+00:00

We may need access to family_id and product_id fairly early on boot for other parts of the code (e.g: biuctrl.c), so split the initialization between an early_init() and an arch_initcall() which allows us to do that. Signed-off-by: Florian Fainelli

soc: brcmstb: biuctrl: Fine tune B53 MCP interface settings

2017-12-21T01:37:43+00:00

In order to achieve expected MCP bus throughput on 3 particular chips: 7268, 7271 and 7278, do the appropriate programming of the MCP interface: increase number of MCP write credits, turn on write-back throttling when present. Signed-off-by: Florian Fainelli

soc: brcmstb: biuctrl: Wire-up new registers

2017-12-21T01:37:42+00:00

Add definitions for B53 systems register: CPU_MCP_FLOW_REG and CPU_WRITEBACK_CTRL_REG. These register will be saved and restored accordingly. Signed-off-by: Florian Fainelli

soc: brcmstb: biuctrl: Prepare for saving/restoring other registers

2017-12-21T01:37:39+00:00

In preparation for saving/restoring additional registers required on some newer platforms (7268, 7271, 7278), migrate the code to use enums and helper functions to access registers. Signed-off-by: Florian Fainelli
