Add clock and reset entries for the Gigabit Ethernet Interfaces (GBETH 0-1) IPs found on the RZ/G3E SoC. This includes various PLLs, dividers, and mux clocks needed by these two GBETH IPs. Reviewed-by: Biju Das Signed-off-by: John Madieu --- Changes: v2: No changes but resending without dt-bindings patch v3: Uses underscores instead of dashes in clock names v4: - Renames clock names to match V2Hs - Uses DEF_MOD_MUX_EXTERNAL instead of DEF_MOD for Tx and Rx clks - Drops Tested-by tag from Biju drivers/clk/renesas/r9a09g047-cpg.c | 64 +++++++++++++++++++++++++++++ 1 file changed, 64 insertions(+) diff --git a/drivers/clk/renesas/r9a09g047-cpg.c b/drivers/clk/renesas/r9a09g047-cpg.c index 21699999cedd..c23cb434a218 100644 --- a/drivers/clk/renesas/r9a09g047-cpg.c +++ b/drivers/clk/renesas/r9a09g047-cpg.c @@ -29,6 +29,7 @@ enum clk_ids { CLK_PLLDTY, CLK_PLLCA55, CLK_PLLVDO, + CLK_PLLETH, /* Internal Core Clocks */ CLK_PLLCM33_DIV3, @@ -46,6 +47,15 @@ enum clk_ids { CLK_PLLDTY_ACPU, CLK_PLLDTY_ACPU_DIV2, CLK_PLLDTY_ACPU_DIV4, + CLK_PLLDTY_DIV8, + CLK_PLLETH_DIV_250_FIX, + CLK_PLLETH_DIV_125_FIX, + CLK_CSDIV_PLLETH_GBE0, + CLK_CSDIV_PLLETH_GBE1, + CLK_SMUX2_GBE0_TXCLK, + CLK_SMUX2_GBE0_RXCLK, + CLK_SMUX2_GBE1_TXCLK, + CLK_SMUX2_GBE1_RXCLK, CLK_PLLDTY_DIV16, CLK_PLLVDO_CRU0, CLK_PLLVDO_GPU, @@ -85,7 +95,18 @@ static const struct clk_div_table dtable_2_64[] = { {0, 0}, };
