From 93cb82477df06ab4f5fdda99a19d3f1b2b7c2eee Mon Sep 17 00:00:00 2001 From: Masahiro Yamada Date: Mon, 1 Aug 2016 00:16:32 +0900 Subject: usb: add CONFIG_USB_OHCI_HCD in Kconfig Add this option as a common config for all OHCI controllers. Its help message was copied from Linux. Also, I moved it below EHCI to respect the order in Linux's Kconfig. Add CONFIG_USB_OHCI_HCD=y to axs103_defconfig, which is the only user of OHCI_GENERIC.

As you see in drivers/usb/Kconfig of Linux, CONFIG_USB enables the USB host controller support, while CONFIG_USB_SUPPORT is used to enable the whole of the USB sub-system. When I added CONFIG_USB into Kconfig by commit 6e7e9294d321 ("usb: add basic USB configs in Kconfig"), I planned to follow the Linux's convention, i.e. CONFIG_USB to enable/disable the USB host support. Then, commit 68f7c5db2d1e ("usb: Generic USB Kconfig option, that fits both host and gadget and comments") changed the logic of the CONFIG_USB to point to the whole of the USB sub-system. As a result, currently we do not have an option for USB host. This commit adds CONFIG_USB_HOST, which will be useful to compile in the USB host support code. CONFIG_USB_HOST is not referenced at all, but strangely some boards define it in board headers. I removed them because USB_HOST will be selected in Kconfig going forward.
