soc: fsl: qbman: Add CGR update function

2022-09-05T13:27:39Z

This adds a function to update a CGR with new parameters. qman_create_cgr can almost be used for this (with flags=0), but it's not suitable because it also registers the callback function. The _safe variant was modeled off of qman_cgr_delete_safe. However, we handle multiple arguments and a return value. Signed-off-by: Sean Anderson Acked-by: Camelia Groza Signed-off-by: David S.

soc: fsl: qbman: Add helper for sanity checking cgr ops

2022-09-05T13:27:39Z

This breaks out/combines get_affine_portal and the cgr sanity check in preparation for the next commit. No functional change intended. Signed-off-by: Sean Anderson Acked-by: Camelia Groza Signed-off-by: David S. Miller

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

soc: fsl: guts: check return value after calling of_iomap() in fsl_guts_get_soc_uid()

2022-07-05T00:41:55Z

of_iomap() may return NULL, so we need check the return value. Reported-by: Hulk Robot Signed-off-by: Yang Yingliang Reviewed-by: Michael Walle Signed-off-by: Shawn Guo

soc: fsl: guts: fix return value check in fsl_guts_init()

2022-07-05T00:41:20Z

In case of error, of_iomap() returns NULL pointer not ERR_PTR(). The IS_ERR() test in the return value check should be replaced with NULL test and return -ENOMEM as error value. Reported-by: Hulk Robot Signed-off-by: Yang Yingliang Reviewed-by: Michael Walle Signed-off-by: Shawn Guo

soc: fsl: guts: add serial_number support

2022-06-27T06:52:02Z

Most layerscapes provide a security fuse processor where the vendor will store a unique id per part. Unfortunately, we cannot use the corresponding efuse driver because this driver needs to be ready early during the boot phase. To get the unique identifier, we just need to access two registers. Thus we just search the device tree for the corresponding device, map its memory to read the id and then unmap it again. Because it is likely that the offset within the fuses is dependent on the SoC, we need a per SoC data. Also, the compatible string is different among the SoCs. For now, this add support for the LS1028A SoC. Signed-off-by: Michael Walle Acked-by: Arnd Bergmann Signed-off-by: Shawn Guo

soc: fsl: guts: drop platform driver

2022-06-27T06:51:59Z

This driver cannot be unloaded and it will be needed very early in the boot process because other driver (weakly) depend on it (eg. for chip errata handling). Drop all the platform driver and devres stuff and simply make it a core_initcall. Signed-off-by: Michael Walle Acked-by: Arnd Bergmann Signed-off-by: Shawn Guo

soc: fsl: guts: use of_root instead of own reference

2022-06-27T06:51:56Z

There is already a global of_root reference. Use that instead of getting one on our own. We don't need to care about the reference count either this way. Signed-off-by: Michael Walle Acked-by: Arnd Bergmann Signed-off-by: Shawn Guo

soc: fsl: guts: allocate soc_dev_attr on the heap

This is the last global static variable. Drop it and allocate the memory on the heap instead. Signed-off-by: Michael Walle Acked-by: Arnd Bergmann Signed-off-by: Shawn Guo
