Add USB clock and EHCI, OHCI, and USB PHY platform devices for R8A7778 SoC; add a function to register PHY device with board-specific platform data and register EHCI and OHCI platfrom devices from the init_late() board method. Also, don't forget to enable CONFIG_ARCH_HAS_[EO]HCI options for R8A7778 SoC in Kconfig... The patch has been tested on the BOCK-W board. Signed-off-by:

The driver currently only supports R8A7779 SoC. Compared to it, R8A7778 USB-PHY has extra register range containing two high-speed signal quality characteristic control registers which should be set up during USB-PHY startup depending on whether a ferrite bead is in use or not. So, we now handle an optional second memory range in the driver's probe method, add the 'ferrite_bead' field to the driver's platform data, and add an extra (optional) step to the USB-PHY startup routine which sets up the extended registers. Also mark in the driver's Kconfig section that R8A7778 is now supported and generally clarify that section, uppercasing the word "phy" and also changing the module name that got lost in the big driver rename, while at it...

Set the USBPCTRL0 register from the passed platform data in rcar_usb_phy_init(); don't reset it to 0 in rcar_usb_phy_shutdown() anymore as that does not make sense. Also, don't allow the driver's probe to succeed when the platform data are not supplied with a device. The patch has been tested on the Marzen and BOCK-W boards. Signed-off-by:

Since we're now going to setup the USBPCTRL0 register using the USB PHY device's platform data, we now need a way to pass those platform data from the board file to the device which is situated in setup-r8a7779.c -- and what I'm suggesting is r8a7779_add_usb_phy_device() that will register USB PHY platform device with the passed platform data using platform_device_register_resndata() call; creating this function involves deletion of 'usb_phy_device' from r8a7779_devices_dt[], so that it will no longer be registered for the generic R8A7779 machine (where we can't provide the platform data anyway), hence EHCI/OHCI drivers will fail to load as well. For the Marzen board, this new function will be called from marzen_init() to register the USB PHY device early enough. Note that the board and the SoC code have to be in one patch to keep the code bisectable... The patch has been tested on the Marzen board. Signed-off-by:

Currently the driver hard-codes USBPCTRL0 register to 0. It is wrong since this register contains board-specific USB ports configuration and so its value should be somehow passed via the platform data. Add the global header file containing 'struct rcar_phy_platform_data' consisting of the various bit fields describing USB ports' pin configuration. Signed-off-by:

The memory region that is used by the driver overlaps EHCI and OHCI register regions for absolutely no reason now -- fix it by adding offset of 0x800 to the base address, changing the register #define's accordingly. This has extra positive effect that we now can use devm_ioremap_resource()... Note that the driver and the SoC code have to be in one patch to keep the code bisectable...

Now that 'drivers/usb/phy/phy-rcar-usb.c' doesn't require the second memory resource anymore, we can remove it from the R8A7779's USB PHY platform device. Signed-off-by:

Now that the EHCI internal buffer setup is done by the platform code, we can remove such code from this driver as it never really belonged here. We also no longer need the 2nd memory region now (2nd EHCI controller is simply missing in e.g. R8A7778 SoC). The patch has been tested on the Marzen and BOCK-W boards. Signed-off-by:

Setup the EHCI internal buffer (before EHCI driver has a chance to touch the registers) using the pre_setup() method in 'struct usb_ehci_pdata'. The patch has been tested on the Marzen board. Signed-off-by:

Sometimes there is a need to initialize some non-standard registers mapped to the EHCI region before accessing the standard EHCI registers. Add pre_setup() method with 'struct usb_hcd *' parameter to be called just before ehci_setup() to the 'ehci-platform' driver's platform data for this purpose... While at it, add the missing incomplete declaration of 'struct platform_device' to <linux/usb/ehci_pdriver.h>... The patch has been tested on the Marzen and BOCK-W boards. Suggested-by:

USB EHCI, OHCI, and common PHY are the SoC devices but are wrongly defined and registered in the Marzen board file. Move the data and code to their proper place in setup-r8a7779.c; while at it, we have to rename r8a7779_late_devices[] to r8a7779_standard_devices[] -- this seems legitimate since they are registered from r8a7779_add_standard_devices() anyway. Note that I'm deliberately changing the USB PHY platform device's 'id' field from (previously just omitted) 0 to -1 as the device is a single of its kind. Note also that the board and SoC code have to be in one patch to keep the code bisectable... The patch has been tested on the Marzen board. Signed-off-by:

This branch acts as a base for adding USB support to r8A7778/BOCK-W and r8A7779/Marzen. It includes the soc branch to provide dependencies in the r8A7778 clock code. It includes pinmux to provide pinmux initialisation for Bock-W which is a dependency.

An earlier commit "ARM: shmobile: sh73a0: add support for adjusting CPU frequency" intended to replace some clock operations only for the Z-clock, instead it replaced them for all div4 clocks, since all div4 clocks share the same copy of clock operations. Fix this by using a separate clock operations structure for Z-clock. Signed-off-by:

Break out the function sh73a0_init_delay() that now gets called both for the C version of the code and the DT -reference boards. This way we handle both cases in the same way. Allows us to boot with TWD only in the kernel configuration for C board code. TWD is not yet enabled in the case of DT -reference - this due to a dependency on CCF. Signed-off-by:

This patch enables the use of the generic cpufreq-cpu0 driver on sh73a0. Providing a regulator, a list of OPPs in DT, combined with a virtual cpufreq-cpu0 platform device and a clock, attached to it is everything, the cpufreq-cpu0 driver needs. The first sh73a0 platform, implementing such CPUFreq support is kzm9g-reference. Signed-off-by:

On SH73A0 the output of PLL0 is supplied to two dividers, feeding clock to the CPU core and SGX. Lower CPU frequencies allow the use of lower supply voltages and thus reduce power consumption. Signed-off-by:

R-Car M1 has many clocks, and it is possible to read/use clock ratio of these clocks from FRQMRx. But, these ratio are fixed value and these are decided by MD pin status. This patch reads MD pin status, and used fixed ratio clock for other clocks. It was tesed on bock-w board. Signed-off-by:
