Commit Message

Andre Przywara Dec. 11, 2020, 1:19 a.m. UTC
Newer SoCs (A100, H616) need to clear a different bit in our "unknown"
PMU PHY register.

Generalise the existing code by allowing configs to specify a bitmask
of bits to clear.

It looks like that the unknown PHY register is PHYCTL register for each
individual PHY, and the bit that is cleared is
called SUNXI_HCI_PHY_CTRL_SIDDQ in the BSP (similar to
the USBC_PHY_CTL_SIDDQ we cleared for main PHYCTL).

Oh, right, somehow I failed to find this in the BSP, I guess I got
confused over that similar symbol. I will put proper names to it.

Thanks!

In addition, both the BIT(1) in old PHYs and the BIT(3) in new PHYs are
SIDDQ. (In BSP it's a #define inside #if)

Should we add some flag for 28nm PHY?

In addition, the region at 0x800 is not PMU at all, but some [OE]HCI-
related control registers. The name "PMU" can only cover the first
register here.

We may need to address this.
