Does omap need similar handing in 5.5-rc1?

  LD      .tmp_vmlinux1
  drivers/soc/ti/omap_prm.o: In function `omap_prm_probe':
  omap_prm.c:(.text+0x4d0): undefined reference to
  `devm_reset_controller_register'
  /data/fast/l/k/Makefile:1077: recipe for target 'vmlinux' failed
  make[1]: *** [vmlinux] Error 1

Enabling reset controller seems to help::

Reset Controller Support (RESET_CONTROLLER) [Y/n/?] (NEW)
  TI SYSCON Reset Driver (RESET_TI_SYSCON) [N/m/y/?] (NEW)

Best regards,
