2023-02-01PM: AVS: qcom-cpr: Fix an error handling path in cpr_probe()Christophe JAILLET1-1/+5
[ Upstream commit 6049aae52392539e505bfb8ccbcff3c26f1d2f0b ] If an error occurs after a successful pm_genpd_init() call, it should be undone by a corresponding pm_genpd_remove(). Add the missing call in the error handling path, as already done in the remove function.

[ Upstream commit 2927cf85f4877f417f884919de8e04ab9b362d32 ] To enable error reporting for a fabric to CCPLEX, we need to write its register for enabling error interrupt to CCPLEX during boot and later clear the error status register after error occurs. If a fabric's registers are protected and not accessible from CCPLEX, then accessing the registers will cause CBB firewall error. Add support to check whether write access from CCPLEX to the registers of a fabric is not blocked by it's firewall before enabling error reporting to CCPLEX for that fabric.

[ Upstream commit 33af51a652191d7b9fe449563594b0bdbeb93c2a ] In Tegra194 SoC, master_id bit range is different between cluster NOC and CBB NOC. Currently same bit range is used which results in wrong master_id value. Due to this, illegal accesses from the CCPLEX master do not result in a crash as expected. Fix this by using the correct range for the CBB NOC. Finally, it is only necessary to extract the master_id when the erd_mask_inband_err flag is set because when this is not set, a crash is always triggered.

2022-09-26pxa: Drop if with an always false conditionUwe Kleine-König1-5/+1
The remove callback is only called after probe completed successfully. In this case platform_set_drvdata() was called with a non-NULL argument and so ssp is never NULL. Also note that returning an error code from a remove callback doesn't result in the device staying bound. It's still removed and devm callbacks are called. So the memory that ssp pointed to during probe, goes away without the node being removed from ssp_list. The probable result of an early exit is accessing freed memory when the list is walked the next time. Signed-off-by: Uwe Kleine-König <(address hidden)> Signed-off-by: Arnd Bergmann <arnd@arndb.de>

Support for SDM845 is added to the sleep stats driver. Power-domains for the SM6375 platform is added to RPMPD and the platform is added to socinfo, together with the PM6125 pmic id.
