[v3,00/15] PHY: Add support in Sierra to use external clock

Message

Kishon Vijay Abraham I Dec. 24, 2020, 11:16 a.m. UTC

Patch series adds support in Sierra driver to use external clock.

v1 of the patch series can be found @ [1]
v2 of the patch series can be found @ [2]

Changes from v2:
1) Add depends on COMMON_CLK in Sierra
2) Add modelling PLL_CMNLC and PLL_CMNLC1 as clocks into a separate
patch
3) Disable clocks in Sierra driver remove

Changes from v1:
1) Remove the part that prevents configuration if the SERDES is already
   configured and focus only on using external clock and the associated
   cleanups
2) Change patch ordering
3) Use exclusive reset control APIs
4) Fix error handling code
5) Include DT patches in this series (I can send this separately to DT
MAINTAINER once the driver patches are merged)
