Patch series adds support in Sierra driver to use external clock. v1 of the patch series can be found @ [1] v2 of the patch series can be found @ [2] Changes from v2: 1) Add depends on COMMON_CLK in Sierra 2) Add modelling PLL_CMNLC and PLL_CMNLC1 as clocks into a separate patch 3) Disable clocks in Sierra driver remove Changes from v1: 1) Remove the part that prevents configuration if the SERDES is already configured and focus only on using external clock and the associated cleanups 2) Change patch ordering 3) Use exclusive reset control APIs 4) Fix error handling code 5) Include DT patches in this series (I can send this separately to DT MAINTAINER once the driver patches are merged) [1] -> http://lore.kernel.org/r/20201103035556.21260-1-kishon@xxxxxx [2] -> http://lore.kernel.org/r/20201222070520.28132-1-kishon@xxxxxx Kishon Vijay Abraham I (15): phy: cadence: Sierra: Fix PHY power_on sequence phy: ti: j721e-wiz: Invoke wiz_init() before of_platform_device_create() dt-bindings: phy: cadence-sierra: Add bindings for the PLLs within SERDES phy: ti: j721e-wiz: Get PHY properties only for "phy" or "link" subnode phy: cadence: cadence-sierra: Create PHY only for "phy" or "link" sub-nodes phy: cadence: cadence-sierra: Move all clk_get_*() to a separate function phy: cadence: cadence-sierra: Move all reset_control_get*() to a separate function phy: cadence: cadence-sierra: Explicitly request exclusive reset control phy: cadence: sierra: Model reference receiver as clocks (gate clocks) phy: cadence: sierra: Model PLL_CMNLC and PLL_CMNLC1 as clocks (mux clocks) phy: cadence: sierra: Enable pll_cmnlc and pll_cmnlc1 clocks arm64: dts: ti: k3-j721e-main: Add DT nodes for clocks within Sierra SERDES arm64: dts: ti: k3-j721e-main: Fix external refclk input to SERDES arm64: dts: ti: k3-j721e-common-proc-board: Use external clock for SERDES arm64: dts: ti: k3-j721e-common-proc-board: Re-name "link" name as "phy" .../bindings/phy/phy-cadence-sierra.yaml | 89 ++- .../dts/ti/k3-j721e-common-proc-board.dts | 57 +- arch/arm64/boot/dts/ti/k3-j721e-main.dtsi | 186 ++++-- drivers/phy/cadence/Kconfig | 1 + drivers/phy/cadence/phy-cadence-sierra.c | 544 ++++++++++++++++-- drivers/phy/ti/phy-j721e-wiz.c | 21 +- 6 files changed, 810 insertions(+), 88 deletions(-) -- 2.17.1
