The goal is to recieve ACKs for all patches in series to merge it via Arnd branch.
It was decided from the very beginning of these series, mostly because
it's a full conversion of platform code to DT and it seemed not
convenient to maintain compatibility with both platform and DT.
Following patches require attention from Stephen Boyd or clk subsystem:
- clk: ep93xx: add DT support for Cirrus EP93xx
It is purely possible to add something like devm_clk_hw_register_fixed_rate_parent_data()
for devm managed version clk_hw_register_fixed_rate_parent_data(), still i would like to
leave for the time after this series if it's all possible.
Couse may be it's better to add something like
devm_clk_hw_register_fixed_rate_index() like it's done for
devm_clk_hw_register_fixed_factor_index().
Changelog for this patch:
- added devm_ep93xx_clk_hw_register_fixed_rate_parent_data() for
devm_ version of clk_hw_register_fixed_rate_parent_data()
- s/devm_clk_hw_register_fixed_rate()/devm_ep93xx_clk_hw_register_fixed_rate_parent_data()/
- replaced all devm_clk_hw_register_fixed_factor() to
devm_clk_hw_register_fixed_factor_parent_hw() or
devm_clk_hw_register_fixed_factor_index()
- s/devm_clk_hw_register_gate()/devm_clk_hw_register_gate_parent_data()
Stephen - it think that's you was aiming for - to get rid of all
functions that are using const char* parent_name directly instead of
clk_hw or clk_parent_data.
Patches should be formated with '--histogram'
