Thanks, Cristi 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 Cristian Ciocaltea (6): clk: actions: Fix UART clock dividers on Owl S500 SoC clk: actions: Fix SD clocks factor table on Owl S500 SoC clk: actions: Fix bisp_factor_table based clocks on Owl S500 SoC clk: actions: Fix AHPPREDIV-H-AHB clock chain on Owl S500 SoC dt-bindings: clock: Add NIC and ETHERNET bindings for Actions S500 SoC clk: actions: Add NIC and ETHERNET clock support for Actions S500 SoC drivers/clk/actions/owl-s500.c | 92 +++++++++++++------- include/dt-bindings/clock/actions,s500-cmu.h | 6 +- 2 files changed, 65 insertions(+), 33 deletions(-)
