soc: ti: pruss: Fix double free in pruss_clk_mux_setup()

2026-03-04T12:20:46Z

[ Upstream commit 80db65d4acfb9ff12d00172aed39ea8b98261aad ] In the pruss_clk_mux_setup(), the devm_add_action_or_reset() indirectly calls pruss_of_free_clk_provider(), which calls of_node_put(clk_mux_np) on the error path. However, after the devm_add_action_or_reset() returns, the of_node_put(clk_mux_np) is called again, causing a double free. Fix by returning directly, to avoid the duplicate of_node_put().

[ Upstream commit 6259094ee806fb813ca95894c65fb80e2ec98bf1 ] In svs_enable_debug_write(), the buf allocated by memdup_user_nul() is leaked if kstrtoint() fails. Fix this by using __free(kfree) to automatically free buf, eliminating the need for explicit kfree() calls and preventing leaks.

pmdomain: imx8mp-blk-ctrl: Keep gpc power domain on for system wakeup

2026-02-11T12:37:20Z

[ Upstream commit e9ab2b83893dd03cf04d98faded81190e635233f ] Current design will power off all dependent GPC power domains in imx8mp_blk_ctrl_suspend(), even though the user device has enabled wakeup capability. The result is that wakeup function never works for such device. An example will be USB wakeup on i.MX8MP. PHY device '382f0040.usb-phy' is attached to power domain 'hsioblk-usb-phy2' which is spawned by hsio block control. A virtual power domain device 'genpd:3:32f10000.blk-ctrl' is created to build connection with 'hsioblk-usb-phy2' and it depends on GPC power domain 'usb-otg2'. If device '382f0040.usb-phy' enable wakeup, only power domain 'hsioblk-usb-phy2' keeps on during system suspend, power domain 'usb-otg2' is off all the time. So the wakeup event can't happen. In order to further establish a connection between the power domains related to GPC and block control during system suspend, register a genpd power on/off notifier for the power_dev. This allows us to prevent the GPC power domain from being powered off, in case the block control power domain is kept on to serve system wakeup.
