Commit Message

Sowjanya Komatineni Jan. 14, 2020, 7:24 a.m. UTC
Current Tegra clock driver registers PMC clocks clk_out_1, clk_out_2,
clk_out_3 and 32KHz blink output in tegra_pmc_init() which does direct
PMC register access during clk_ops and these PMC register read and write
access will not happen when PMC is in secure mode.

Any direct PMC register access from non-secure world will not go
through.

All the PMC clocks are moved to Tegra PMC driver with PMC as a clock
provider.

This patch removes tegra_pmc_clk_init along with corresponding clk ids
from Tegra clock driver.

I think it's best to defer this patch (along with 21 and 22) until all
the others have been merged to make sure we don't regress. Other than
that it should be fine to apply the others in any order, right? Well,
maybe not any order, but at least the ASoC patches should be able to
go through the ASoC tree without impacting functionality, right?
