soc: bcm: brcmstb: biuctrl: Avoid double of_node_put()

2022-09-15T21:30:29Z

Commit 9a073d4fbb18 ("soc: bcm: brcmstb: biuctrl: Add missing of_node_put()") added what was thought to be a missing of_node_put() but now causes a double of_node_put() to be called, once from setup_hifcpubiuctrl_regs() and another time from brcmstb_biuctrl_init(). Ensure that setup_hifcpubiuctrl_regs() is not calling of_node_put() since it is not obvious it does that on one of its parameters.

soc: sunxi: sram: Fix debugfs info for A64 SRAM C

2022-09-08T20:28:42Z

The labels were backward with respect to the register values. The SRAM is mapped to the CPU when the register value is 1.

soc: sunxi: sram: Fix probe function ordering issues

2022-09-08T20:28:03Z

Errors from debugfs are intended to be non-fatal, and should not prevent the driver from probing. Since debugfs file creation is treated as infallible, move it below the parts of the probe function that can fail. This prevents an error elsewhere in the probe function from causing the file to leak. Do the same for the call to of_platform_populate(). Finally, checkpatch suggests an octal literal for the file permissions.

soc: sunxi: sram: Prevent the driver from being unbound

2022-09-08T20:27:24Z

This driver exports a regmap tied to the platform device (as opposed to a syscon, which exports a regmap tied to the OF node). Because of this, the driver can never be unbound, as that would destroy the regmap. Use builtin_platform_driver_probe() to enforce this limitation.

soc: sunxi: sram: Actually claim SRAM regions

2022-09-08T20:25:38Z

sunxi_sram_claim() checks the sram_desc->claimed flag before updating the register, with the intent that only one device can claim a region. However, this was ineffective because the flag was never set.

soc: fsl: select FSL_GUTS driver for DPIO

2022-09-02T09:28:40Z

The soc/fsl/dpio driver will perform a soc_device_match() to determine the optimal cache settings for a given CPU core. If FSL_GUTS is not enabled, this search will fail and the driver will not configure cache stashing for the given DPIO, and a string of "unknown SoC" messages will appear: fsl_mc_dpio dpio.7: unknown SoC version fsl_mc_dpio dpio.6: unknown SoC version fsl_mc_dpio dpio.5: unknown SoC version Fixes: 51da14e96e9b ("soc: fsl: dpio: configure cache stashing destination") Signed-off-by: Mathew McBride Reviewed-by: Ioana Ciornei Cc: stable@vger.kernel.org Link: https://lore.kernel.org/r/20220901052149.23873-2-matt@traverse.com.au' Signed-off-by: Arnd Bergmann
