merged this driver to linux-phy tree. Can you send a separate patch
adding yourself as the maintainer of this driver?

Thanks

We have a pool of maintainers to maintain all iProc based device drivers
(including this PCIe PHY driver for Cygnus):

BROADCOM IPROC ARM ARCHITECTURE
M:      Ray Jui <rjui@broadcom.com>
M:      Scott Branden <sbranden@broadcom.com>
M:      Jon Mason <jonmason@broadcom.com>
L:      linux-arm-kernel@lists.infradead.org (moderated for non-subscribers)
L:      bcm-kernel-feedback-list@broadcom.com
T:      git git://github.com/broadcom/cygnus-linux.git
S:      Maintained
N:      iproc
N:      cygnus
N:      nsp
...
...

That should be sufficient, correct?

Thanks,

Ray
