Merge tag 'omap-for-v5.10/fixes-rc5-signed' of git://git.kernel.org/pub/scm/linux/kernel/git/tmlind/linux-omap into arm/fixes
Fixes for omaps for various issues noticed during the -rc cycle: - Earlier omap4 cpuidle fix was incomplete and needs to use a configured idle state instead - Fix am4 cpsw driver compatible to avoid invalid resource error for the legacy driver - Two kconfig fixes for genpd support that we added for for v5.10 for proper location of the option and adding missing option - Fix ti-sysc reset status checking on enabling modules to ignore quirky modules with reset status only usable when the quirk is activated during reset. Also fix bogus resetdone warning for cpsw and modules with no sysst register reset status bit - Suppress a ti-sysc warning for timers reserved as system timers - Fix the ordering of clocks for dra7 m_can * tag 'omap-for-v5.10/fixes-rc5-signed' of git://git.kernel.org/pub/scm/linux/kernel/git/tmlind/linux-omap: ARM: dts: dra76x: m_can: fix order of clocks bus: ti-sysc: suppress err msg for timers used as clockevent/source ARM: dts: am437x-l4: fix compatible for cpsw switch dt node ARM: OMAP2+: Manage MPU state properly for omap_enter_idle_coupled() bus: ti-sysc: Fix bogus resetdone warning on enable for cpsw bus: ti-sysc: Fix reset status check for modules with quirks ARM: OMAP2+: Fix missing select PM_GENERIC_DOMAINS_OF ARM: OMAP2+: Fix location for select PM_GENERIC_DOMAINS Link: https://lore.kernel.org/r/pull-1606460270-864284@atomide.com Signed-off-by: Arnd Bergmann <arnd@arndb.de>
