Subject: Re: [PATCH v2 18/22] phy: apple: Add Apple Type-C PHY

In functions like atcphy_dp_configure_lane, I'm wondering if we want to
pull out individual registers like `void __iomem *tx_shm_txa_ldoclk =
tx_shm + LN_AUSPMA_TX_SHM_TXA_LDOCLK`, likewise for
MAIN_REG0/1/IMP_REG0/etc, just to make the actual pokes below a lot less
noisy.

Incidentally, the txa_ldoclk_bypass handling is another place where the
cond_set32 helper would shine.

Also, do we know what _OV means?
