…ke sure bridging is working properly. Note tags are disabled in this version, and a lot of register values are hacked in.
…level. Still need to test if they are maintained through port enables/disables. Also need to do lots of cleanup, there's a lot a test code in there.
On powerup, cpu has no headers / imp has headers. PVLANs all set to zero (no connections between ports) Port0-Port4 PHY and MACs disabled.
…Ns for all ports.
… delays. Version 5.15.107-datum.6
…s, monitor RMGII link status, etc. Version 5.15.107-datum.7
… vectors for each port to include self on driver init.
…not 2 seconds. Add mutex between i2c devices and spi Broadcom switch to use a mutex to lock access to the schematic error that links the clock pins on i2c3 and spi2.
…pi/i2c actrivity in an attempt to get the spi crash to occur more often.
…ode to insure the device using the bus is asleep before releasing mutex.
…ime_suspended() instead of pm_runtime_active to exclude states where device is becoming active or becoming suspended.
…ll has the problem.
…ck and unlock the mutex during a complete read or write transaction. Each read/write transaction contains multiple SPI bus accesses.
…me debug code. This appears to work, need to setup the pm autodisable for only the spi/i2c busses with the problem, then separate the i2c drivers into unmodified for the m7xc and modified for the t7xc.
…and i2c device memory (only use i2c if timer expired).
…02 drivers into those that supports I2C/SPI clock short and those that don't. Needed for one kernel to support both the T7XC and M7XC. This version still has increased BR53134, INA2236 and MCP9902 bus activity for testing.
… only grab/release the mutex once during multiple register reads.
… driver. Ready for release.

[ Upstream commit e3e82fc ] When creating ceq_0 during probing irdma, cqp.sc_cqp will be sent as a cqp_request to cqp->sc_cqp.sq_ring. If the request is pending when removing the irdma driver or unplugging its aux device, cqp.sc_cqp will be dereferenced as wrong struct in irdma_free_pending_cqp_request().
