While working on a driver to support the Actions Semi Owl Ethernet MAC,
I found and fixed some issues on the existing implementation of the S500
SoC clock subsystem and, additionally, I added two missing clocks.
Thanks,
Cristi
Changes in v3:
- Fixed swapped flags between "ahbprediv_clk" and "ahb_clk" in patch 4/6
- Added Reviewed-by tags from Mani
- Rebased patch series on v5.13-rc5
Changes in v2 (according to Mani's review):
- Re-added entry "{ 24, 1, 25 }" to sd_factor_table, according to the
datasheet (V1.8+), this is a valid divider
- Re-added OWL_GATE_HW to SENSOR[0-1], according to the datasheet they
are gated, even though the vendor implementation states the opposite
- Reverted the addition of the clock div table for H clock to support the
'1' divider (according to the datasheet), even though the vendor
implementation marks it as reserved
- Reordered "nic_clk_mux_p" after "ahbprediv_clk_mux_p" to follow the reg
field ordering
- Rebased patch series on v5.13-rc3
