* phy: ti: j721e-wiz: Implement DisplayPort mode to the wiz driverJyri Sarha2020-04-241-4/+55
| | | | | | | | | | | | | | | | For DisplayPort use we need to set WIZ_CONFIG_LANECTL register's P_STANDARD_MODE bits to "mode 3". 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.

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.

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 ...

Support fo USB3 will be added later. SERDES in am654x has three input clocks (left input, externel reference clock and right input) and two output clocks (left output and right output) in addition to a PLL mux clock which the SERDES uses for Clock Multiplier Unit (CMU refclock). The PLL mux clock can select from one of the three input clocks. The right output can select between left input and external reference clock while the left output can select between the right input and external reference clock. The driver has support to select PLL mux and left/right output mux as specified in device tree.

|/ | | | | | | | | | | | | | | | | | | | | | | | | | | With the recent regulator changes I noticed new warnings on doing rmmod of phy-twl4030-usb: WARNING: CPU: 0 PID: 1080 at drivers/regulator/core.c:2046 _regulator_put ... Turns out we can currently miss disconnect at least for cases where status is 0 and linkstat is 0. And in that case doing rmmod phy-twl4030-usb will produce the regulator_put() warning. This is because the missed disconnect causes unbalanced PM runtime calls and the regulators will be on exit. Let's fix the issue by using an atomic flag for the cable state to make sure that PM runtime won't get out of sync with the cable state. That way we can also simplify the code a bit. Note that we can also drop the old comments, those relate to issues that the battery charger driver and musb driver is dealing with rather than the USB PHY driver.
