Merge tag 'omap-for-v5.6/ti-sysc-signed' of git://git.kernel.org/pub/scm/linux/kernel/git/tmlind/linux-omap into arm/drivers
ti-sysc driver changes for omaps for v5.6 merge window Few changes to implement quirk handling for cases where we need to block clockdomain autoidle, drop old MMU specific quirks, and simplify the return code for sysc_init_resets(). * tag 'omap-for-v5.6/ti-sysc-signed' of git://git.kernel.org/pub/scm/linux/kernel/git/tmlind/linux-omap: bus: ti-sysc: Use PTR_ERR_OR_ZERO() to simplify code bus: ti-sysc: Drop MMU quirks bus: ti-sysc: Implement quirk handling for CLKDM_NOAUTO Link: https://lore.kernel.org/r/pull-1579200367-372444@atomide.com-3 Signed-off-by: Olof Johansson <olof@lixom.net>
