Correct SPL uses of USB_MUSB_HOST

2023-02-10T12:41:40+00:00

This converts 2 usages of this option to the non-SPL form, since there is
no SPL_USB_MUSB_HOST defined in Kconfig

global: Finish CONFIG -> CFG migration

2023-01-20T17:27:24+00:00

At this point, the remaining places where we have a symbol that is
defined as CONFIG_... are in fairly odd locations. While as much dead
code has been removed as possible, some of these locations are simply
less obvious at first. In other cases, this code is used, but was
defined in such a way as to have been missed by earlier checks.  Perform
a rename of all such remaining symbols to be CFG_... rather than
CONFIG_...

phy: rockchip: handle clock without enable function

2022-12-19T02:56:12+00:00

If a clock doesn't supply the enable hook, clk_enable() will return
-ENOSYS.  In this case the clock is always enabled so there is no error
and the phy initialisation should continue.

phy: usbphyc: use regulator_set_enable_if_allowed for disabling vbus supply

2022-12-12T10:25:19+00:00

Use regulator_set_enable_if_allowed() api instead of regulator_set_enable()
while disabling vbus supply. This way the driver doesn't see an error
when it disable an always-on regulator for VBUS.

This patch is needed for STM32MP157C-DK2 board when the regulator
v3v3: buck4 used as the phy vbus supply in kernel device tree
is always on with the next hack for low power use-case:

&usbphyc_port0 {
        ...
	/*
	 * Hack to keep hub active until all connected devices are suspended
	 * otherwise the hub will be powered off as soon as the v3v3 is disabled
	 * and it can disturb connected devices.
	 */
	connector {
		compatible = "usb-a-connector";
		vbus-supply = <&v3v3>;
	};
};

Without this patch and the previous update in DT the command
"usb stop" failed and the next command "usb start" cause a crash.

2022-10-18T13:48:22+00:00

Add support for j784s4-wiz-10g device which has two core reference
clocks (e.g core_ref_clk, core_ref1_clk) which requires an additional
mux selection option.

phy: Add generic_{setup,shutdown}_phy() helpers

2022-10-10T16:08:18+00:00

In drivers usb/host/{ehci,ohci}-generic.c, {ehci,ohci}_setup_phy() and
{ehci,ohci}_shutdown_phy() shares 95% of common code.
Factorize this code in new generic_{setup,shudown}_phy() functions.

Add the counter of the PLL user n_pll_cons managed by the 2 functions
stm32_usbphyc_pll_enable / stm32_usbphyc_pll_disable.

This counter allow to remove the function stm32_usbphyc_is_init

QCS404 SoC supports two types of PHY, one supports high speed mode or
USB2 PHY and the other supports super speed mode or USB3 PHY. So add
corresponding PHY drivers.
