2021-03-30phy: ti: j721e-wiz: Enable reference clock output in cmn_refclk_<p/m>Kishon Vijay Abraham I
cmn_refclk_<p/m> lines in Torrent SERDES is used for connecting external reference clock. cmn_refclk_<p/m> can also be configured to output the reference clock. In order to drive the refclk out from the SERDES (Cadence Torrent), PHY_EN_REFCLK should be set in SERDES_RST of WIZ. Model PHY_EN_REFCLK as a clock, so that platforms like AM642 EVM can enable it.

2021-03-30phy: ti: j721e-wiz: Model the internal clocks without device tree inputKishon Vijay Abraham I
commit 091876cc355d ("phy: ti: j721e-wiz: Add support for WIZ module present in TI J721E SoC") modeled the internal clocks depending on the subnodes that are populated in device tree. However recent discussions in the mailing list [1] suggested to just add #clock cells in the parent DT node and model the clocks within the driver. Model the mux clocks without device tree input for AM64x SoC. Don't remove the earlier design since DT nodes for J7200 and J721e are already upstreamed.

2021-03-30phy: ti: j721e-wiz: Remove "regmap_field" from wiz_clk_{mux|div}_selKishon Vijay Abraham I
Both "struct wiz_clk_div_sel" and "struct wiz_clk_mux_sel" are static data that is common for all wiz instances. Including "struct regmap_field" for each of the wiz instances can yield undesirable results. Move "struct regmap_field" out of "struct wiz_clk_div_sel" and "struct wiz_clk_mux_sel" and make them point to constant data. So far no issues are observed since both these structures are not accessed outside the probe.

In the DisplayPort use also the P_ENABLE bits of the same register are set to P_ENABLE instead of P_ENABLE_FORCE, so that the DisplayPort driver can enable and disable the lane as needed. The DisplayPort mode is selected according to "cdns,phy-type"-properties found in link subnodes under the managed serdes (see "ti,sierra-phy-t0" and "ti,j721e-serdes-10g" devicetree bindings for details). All other values of "cdns,phy-type"-property but PHY_TYPE_DP will set P_STANDARD_MODE bits to 0 and P_ENABLE bits to force enable.

2020-01-14phy: ti: j721e-wiz: Manage typec-gpio-dirRoger Quadros
Based on this GPIO state we need to configure LN10 bit to swap lane0 and lane1 if required (flipped connector). Type-C companions typically need some time after the cable is plugged before and before they reflect the correct status of Type-C plug orientation on the DIR line. Type-C Spec specifies CC attachment debounce time (tCCDebounce) of 100 ms (min) to 200 ms (max). Use the DT property to figure out if we need to add delay or not before sampling the Type-C DIR line.

Add support for WIZ module present in TI's J721E SoC. WIZ is a SERDES wrapper used to configure some of the input signals to the SERDES. It is used with both Sierra(16G) and Torrent(10G) SERDES. This driver configures three clock selects (pll0, pll1, dig), two divider clocks and supports resets for each of the lanes.

git://git.kernel.org/pub/scm/linux/kernel/git/clk/linux Pull clk updates from Stephen Boyd: "We have a small collection of core framework updates this time, mostly around clk registration by clk providers and debugfs "nice to haves" for rate constraints. I'll highlight that we're now setting the clk_init_data pointer inside struct clk_hw to NULL during clk_register(), which may break some drivers that thought they could use that pointer during normal operations. That change has been sitting in next for a while now but maybe something is still broken. We'l see. Other than that the core framework changes aren't invasive and they're fixing bugs, simplifying, and making things better. On the clk driver side we got the usual addition of new SoC support, new features for existing drivers, and bug fixes scattered throughout. The biggest diffstat is the Amlogic driver that gained CPU clk support in addition to migrating to the new way of specifying clk parents. After that the Qualcomm, i.MX, Mediatek, and Rockchip clk drivers got support for various new SoCs and clock controllers from those vendors. Core: - Drop NULL checks in clk debugfs - Add min/max rates to clk debugfs - Set clk_init_data pointer inside clk_hw to NULL after registration - Make clk_bulk_get_all() return an 'id' corresponding to clock-names - Evict parents from parent cache when they're unregistered New Drivers: - Add clock driver for i.MX8MN SoCs - Support aspeed AST2600 SoCs - Support for Mediatek MT6779 SoCs - Support qcom SM8150 GCC and RPMh clks - Support qcom QCS404 WCSS clks - Add CPU clock support for Armada 7K/8K (specifically AP806 and AP807) - Addition of clock driver for Rockchip rk3308 SoCs Updates: - Add regulator support to the cdce925 clk driver - Add support for Raspberry Pi 4 bcm2711 SoCs - Add SDIO gate support to aspeed driver - Add missing of_node_put() calls in various clk drivers - Migrate Amlogic driver to new clock parent description method - Add DVFS support to Amlogic Meson g12 - Add Amlogic Meson g12a reset support to the axg audio clock controller - Add sm1 support to the Amlogic Meson g12a clock controller - Switch i.MX8MM clock driver to platform driver - Add Hifi4 DSP related clocks for i.MX8QXP SoC - Fix Audio PLL setting and parent clock for USB - Misc i.MX8 clock driver improvements and corrections - Set floor ops for Qualcomm SD clks so that rounding works - Fix "always-on" Clock Domains on Renesas R-Car M1A, RZ/A1, RZ/A2, and RZ/N1 - Enable the Allwinner V3 SoC and fix the i2s clock for H6" * tag 'clk-for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/clk/linux: (137 commits) clk: Drop !clk checks in debugfs dumping clk: imx: imx8mn: fix pll mux bit clk: imx: imx8mm: fix pll mux bit clk: imx: clk-pll14xx: unbypass PLL by default clk: imx: pll14xx: avoid glitch when set rate clk: mvebu: ap80x: add AP807 clock support clk: mvebu: ap806: Prepare the introduction of AP807 clock support clk: mvebu: ap806: add AP-DCLK (hclk) to system controller driver clk: mvebu: ap806: be more explicit on what SaR is clk: mvebu: ap80x-cpu: add AP807 CPU clock support clk: mvebu: ap806-cpu: prepare mapping of AP807 CPU clock dt-bindings: ap806: Document AP807 clock compatible dt-bindings: ap80x: Document AP807 CPU clock compatible clk: sprd: add missing kfree clk: at91: allow 24 Mhz clock as input for PLL clk: Make clk_bulk_get_all() return a valid "id" clk: actions: Fix factor clk struct member access clk: qcom: rcg: Return failure for RCG update clk: remove extra ---help--- tags in Kconfig clk: add include guard to clk-conf.h ...
