* ARM: AM33xx: PRM: Implement REBOOT_COLDAlexander Sverdlin2024-02-281-1/+2
| | | | | | | | | | | | Historically AM33xx performed warm software reset even though requested (and default) was REBOOT_COLD. Reflect the de-facto default mode in /sys/kernel/reboot/mode correctly and implement the real REBOOT_COLD (if configured explicitly).

* ARM: OMAP2+: am33xx-restart: fix function name in kernel-docRandy Dunlap2024-01-261-1/+1
| | | | | | | | | | | | | | | | Use the correct name in kernel-doc notation to prevent a kernel-doc warning: am33xx-restart.c:20: warning: expecting prototype for am3xx_restart(). Prototype was for am33xx_restart() instead Signed-off-by: Randy Dunlap <rdunlap@infradead.org> Cc: Tony Lindgren <tony@atomide.com> Cc: linux-omap@vger.kernel.org Cc: Russell King <linux@armlinux.org.uk> Cc: linux-arm-kernel@lists.infradead.org Cc: patches@armlinux.org.uk Message-ID: <20240117011004.22669-2-rdunlap@infradead.org> Signed-off-by: Tony Lindgren <tony@atomide.com>

* ARM: OMAP2+: PRM: provide generic API for system resetTero Kristo2014-10-271-3/+2
| | | | | | | | | | | This patch combines the various prm_warm_reset calls under a common API prm_reset_system, and adds the SoC specific implementation under prm_ll_data.

* ARM: AM33xx: PRM: move global warm reset implementation to driverTero Kristo2014-10-271-8/+1
| | | | | | | | | | Moved the implementation from am33xx-restart.c to the prm33xx.c file to isolate the PRM register accesses to be private for PRM driver.

* ARM: OMAP2+: am33xx-restart: trigger warm reset on omap2+ boardsMatus Ujhelyi2013-08-211-2/+2
| | | | | | | | Currently the cold reset was triggered. It happened due to oposite offsets of cold/warm flags in PRM_RSTST and PRM_RSTCTRL registers. Signed-off-by: Matus Ujhelyi <ujhelyi.m@gmail.com> Signed-off-by: Tony Lindgren <tony@atomide.com>
* reboot: arm: change reboot_mode to use enum reboot_modeRobin Holt2013-07-091-1/+2
| | | | | | | | | | | | | | | | Preparing to move the parsing of reboot= to generic kernel code forces the change in reboot_mode handling to use the enum.
