Merge tag 'omap-for-v4.21/driver-signed' of git://git.kernel.org/pub/scm/linux/kernel/git/tmlind/linux-omap into next/drivers
Driver changes for omaps for v4.21 merge window Few SoC related driver changes to add PRCM as the wake-up source for wkup_m3_ipc driver, and to improve ti-sysc driver for dra7 mcasp and device detection when debug is enabled. There is also a non-critical fix for ti-sysc to fix handling of the optional clocks but this can wait for the merge window no problem. * tag 'omap-for-v4.21/driver-signed' of git://git.kernel.org/pub/scm/linux/kernel/git/tmlind/linux-omap: soc: ti: wkup_m3: Add PRCM int16 as the wake up source bus: ti-sysc: Detect devices for debug on omap5 bus: ti-sysc: Add mcasp optional clocks flag bus: ti-sysc: Fix getting optional clocks in clock_roles Signed-off-by: Olof Johansson <olof@lixom.net>
