[PATCH net-next v3 0/2] Fix CPTS release action in am65-cpts driver

[Siddharth Vadapalli]

Delete unreachable code in am65_cpsw_init_cpts() function, which was
Reported-by: Leon Romanovsky <leon@kernel.org>
at:
https://lore.kernel.org/r/Y8aHwSnVK9+sAb24@unreal

Remove the devm action associated with am65_cpts_release() and invoke the
function directly on the cleanup and exit paths.

Changes from v2:
1. Drop Reviewed-by tag from Roger Quadros.
2. Add cleanup patch for deleting unreachable error handling code in
   am65_cpsw_init_cpts().
3. Drop am65_cpsw_cpts_cleanup() function and directly invoke
   am65_cpts_release().

Changes from v1:
1. Fix the build issue when "CONFIG_TI_K3_AM65_CPTS" is not set. This
   error was reported by kernel test robot <lkp@intel.com> at:
   https://lore.kernel.org/r/202301142105.lt733Lt3-lkp@intel.com/

[PATCH net-next v3 1/2] net: ethernet: ti: am65-cpsw: Delete unreachable error handling code

[Siddharth Vadapalli]

The am65_cpts_create() function returns -EOPNOTSUPP only when the config
"CONFIG_TI_K3_AM65_CPTS" is disabled. Also, in the am65_cpsw_init_cpts()
function, am65_cpts_create() can only be invoked if the config
"CONFIG_TI_K3_AM65_CPTS" is enabled. Thus, the error handling code for the
case in which the return value of am65_cpts_create() is -EOPNOTSUPP, is
unreachable. Hence delete it.

[PATCH net-next v3 2/2] net: ethernet: ti: am65-cpsw/cpts: Fix CPTS release action

[Siddharth Vadapalli]

The am65_cpts_release() function is registered as a devm_action in the
am65_cpts_create() function in am65-cpts driver. When the am65-cpsw driver
invokes am65_cpts_create(), am65_cpts_release() is added in the set of devm
actions associated with the am65-cpsw driver's device.

In the event of probe failure or probe deferral, the platform_drv_probe()
function invokes dev_pm_domain_detach() which powers off the CPSW and the
CPSW's CPTS hardware, both of which share the same power domain. Since the
am65_cpts_disable() function invoked by the am65_cpts_release() function
attempts to reset the CPTS hardware by writing to its registers, the CPTS
hardware is assumed to be powered on at this point. However, the hardware
is powered off before the devm actions are executed.

Fix this by getting rid of the devm action for am65_cpts_release() and
invoking it directly on the cleanup and exit paths.

[PATCH net-next v4 2/2] net: ethernet: ti: am65-cpsw/cpts: Fix CPTS release action

[Siddharth Vadapalli]

The am65_cpts_release() function is registered as a devm_action in the
am65_cpts_create() function in am65-cpts driver. When the am65-cpsw driver
invokes am65_cpts_create(), am65_cpts_release() is added in the set of devm
actions associated with the am65-cpsw driver's device.

In the event of probe failure or probe deferral, the platform_drv_probe()
function invokes dev_pm_domain_detach() which powers off the CPSW and the
CPSW's CPTS hardware, both of which share the same power domain. Since the
am65_cpts_disable() function invoked by the am65_cpts_release() function
attempts to reset the CPTS hardware by writing to its registers, the CPTS
hardware is assumed to be powered on at this point. However, the hardware
is powered off before the devm actions are executed.

Fix this by getting rid of the devm action for am65_cpts_release() and
invoking it directly on the cleanup and exit paths.

Sorry, I wasn't aware of this. Paolo asked me to re-spin, so I thought that I
had to use the "--in-reply-to" option. I will repost the series. Could you let
me know if v4 will be the right version for the series or should it be v5,
considering that the re-spin patch has v4 in subject.
