* soc: bcm: brcmstb: biuctrl: Avoid double of_node_put()Florian Fainelli2022-09-151-1/+0
| | | | | | | | | | | | | | | 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.

| | | | | | | | | | | | | | | | | Brahma-B53 and Cortex-A72 CPUs integrated on Broadcom STB SoCs feature a read-ahead cache that performs cache line size adaptation between the bus interface unit and the memory controller. On 32-bit ARM kernels we have to resort to a full featured read-ahead cache driver under arch/arm/mm/cache-b15-rac.c (CONFIG_CACHE_B15_RAC) because there are still cache maintenance operations by set/ways/index that cannot be transparently handled by the ARM Coherency Extension that the read-ahead cache interfaces to.

| | | | | | | | | | | | | | | | | | | | 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 <f.fainelli@gmail.com>

| | | | | | | | | | | | | | | | | | | | | | 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.
