GbEthernet clock support involves handing mux clock support for HP clock and coupled clock for axi/chi module clocks which shares same bit for controlling the clock output. This patch series is based on renesas-clk-for-v5.15. v2->v3: * Rebased to latest renesas-clk * Updated commit header for all patches * Replaced CLK_PLL5_2 with PLL5_FOUT3 * Removed CLK_PLL6_2 and pll6_2 as the clk is sourced from PLL6 * Added enabled flag to track the status of clock, if it is coupled with another clock * Introduced siblings pointer which points to the other coupled clock * coupled clock linking is done during module clk register. * rzg2l_mod_clock_is_enabled function returns soft state of the module clocks, if it is coupled with another clock v1->v2: * No change. Separated clock patches from driver patch series as per [1] [1] https://www.spinics.net/lists/linux-renesas-soc/msg59067.html v1:- * New patch Biju Das (4): clk: renesas: rzg2l: Add support to handle MUX clocks clk: renesas: r9a07g044: Add ethernet clock sources clk: renesas: rzg2l: Add support to handle coupled clocks clk: renesas: r9a07g044: Add GbEthernet clock/reset drivers/clk/renesas/r9a07g044-cpg.c | 29 +++++++++- drivers/clk/renesas/rzg2l-cpg.c | 85 +++++++++++++++++++++++++++++ drivers/clk/renesas/rzg2l-cpg.h | 26 ++++++++- 3 files changed, 138 insertions(+), 2 deletions(-)
