| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This patch adds support for MIPI DPHYs found in Exynos5420-compatible (5420, 5422 and 5800) and Exynos5433 SoCs. Those SoCs differs from earlier by different offset of MIPI DPHY registers in PMU controllers (Exynos 5420-compatible case) or by moving MIPI DPHY reset registers to separate system register controllers (Exynos 5433 case). In both case also additional 5th PHY (MIPI CSIS 2) has been added.

| | * phy: exynos-mipi-video: Rewrite handling of phy registersMarek Szyprowski2016-04-301-35/+130
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Controlling Exynos MIPI DPHY is done by handling 2 registers: one for phy reset and one for enabling it. This patch moves definitions of those 2 registers to speparate exynos_mipi_phy_desc structure, which can be defined separately for each PHY for each supported hardware variant. This code rewrite is needed to add support for newer Exynos SoCs, which have MIPI PHY related registers at different offsets or even different register regions.

| | * phy: bcm-ns-usb2: new driver for USB 2.0 PHY on NorthstarRafał Miłecki2016-04-303-0/+147
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Northstar is a family of SoCs used in home routers. They have USB 2.0 and 3.0 controllers with PHYs that need to be properly initialized. This driver provides PHY init support in a generic way and can be bound with an EHCI controller driver. There are (just a few) registers being defined in bcma header. It's because DMU/CRU registers will be also needed in other drivers. We will need them e.g. in PCIe controller/PHY driver and at some point probably in clock driver for BCM53573 chipset. By using include/linux/bcma/ we avoid code duplication.

This time not as large as usual with only 57 non-merge commits. The most important part here is, again, all the work on dwc3. This time around we're treating all endpoints (except for control endpoint) exactly the same. They all have the same amount of TRBs on the ring, they all treat the ring as an actual ring with a link TRB pointing to the head, etc. We're also helping the host side burst (on SuperSpeed GEN1 or GEN2 at least) for as long as possible until the endpoint returns NRDY. Other than this big TRB ring rework on dwc3, we also have a dwc3-omap DMA initialization fix, some extra debugfs files to aid in some odd debug sessions and a complete removal of our FIFO resizing logic. We have a new quirk for some dwc3 P3 quirk in some implementations. The rest is basically non-critical fixes and the usual cleanups.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Most newer Rockchip SoCs provide the possibility to use a usb-phy as passthrough for the debug uart (uart2), making it possible to for example get console output without needing to open the device. This patch adds an early_initcall to enable this functionality conditionally via the commandline and also disables the corresponding usb controller in the devicetree. Currently only data for the rk3288 is provided, but at least the rk3188 and arm64 rk3368 also provide this functionality and will be enabled later. On a spliced usb cable the signals are tx on white wire(D+) and rx on green wire(D-). The one caveat is that currently the reconfiguration of the phy happens as early_initcall, as the code depends on the unflattened devicetree being available. Everything is fine if only a regular console is active as the console-replay will happen after the reconfiguation. But with earlycon active output up to smp-init currently will get lost. The phy is an optional property for the connected dwc2 controller, so we still provide the phy device but fail all phy-ops with -EBUSY to make sure the dwc2 does not try to transmit anything on the repurposed phy.

* phy: twl4030-usb: Fix unbalanced pm_runtime_enable on module reloadTony Lindgren2016-02-101-5/+8
| | | | | | | | | | | | | | | | | | If we reload phy-twl4030-usb, we get a warning about unbalanced pm_runtime_enable. Let's fix the issue and also fix idling of the device on unload before we attempt to shut it down. If we don't properly idle the PHY before shutting it down on removal, the twl4030 ends up consuming about 62mW of extra power compared to running idle with the module loaded.

The phy-omap-control driver is not an 'actual' PHY driver and it was just a hack to do PHY related control module initialization. Now with SYSCON framework in the kernel, control module setttings can be done using APIs provided by syscon. *) usbphy-internal pll creates the needed 480MHz and is also a supply-clock back to the core clock-controller in Rockchip SoCs. This is now modeled as a real clock. *) calibrate mt65xx usb3 PHY for better eye diagram and receiver sensitivity. *) Miscellaneous cleanups. Signed-off-by: Kishon Vijay Abraham I <kishon@ti.com>
