[OpenWrt-Devel] ar71xx/ath79: at803x_platform_data: reset_gpio

[Adrian Schmutzler]

Hi,

during support of the Ubiquiti Nanostation Loco XW, we encountered the following
blocks in ar71xx which are only present for devices not migrated to ath79 yet:

static struct mdio_board_info ubnt_loco_m_xw_mdio_info[] = {
	{
		[...]
		.platform_data = &ubnt_loco_m_xw_at803x_data,
	},
};
static struct at803x_platform_data ubnt_loco_m_xw_at803x_data = {
	.has_reset_gpio = 1,
	.reset_gpio = 0,
};

How is this translated into ath79? The Loco XW (just merged to master [1]) seems
to work well with the setup we have right now, other devices with reset_gpio are
few:

adsc at buildfff:/data/openwrt$ grep -rn "reset_gpio"
target/linux/ar71xx/files/arch/
target/linux/ar71xx/files/arch/mips/ath79/mach-rambutan.c:35:   .has_reset_gpio
= 1,
target/linux/ar71xx/files/arch/mips/ath79/mach-rambutan.c:36:   .reset_gpio =
17,
target/linux/ar71xx/files/arch/mips/ath79/mach-rambutan.c:48:   .has_reset_gpio
= 1,
target/linux/ar71xx/files/arch/mips/ath79/mach-rambutan.c:50:   .reset_gpio =
23,
target/linux/ar71xx/files/arch/mips/ath79/mach-ubnt-xm.c:485:   .has_reset_gpio
= 1,
target/linux/ar71xx/files/arch/mips/ath79/mach-ubnt-xm.c:486:   .reset_gpio = 0,
target/linux/ar71xx/files/arch/mips/ath79/mach-fritz450e.c:124: .has_reset_gpio
= 1,
target/linux/ar71xx/files/arch/mips/ath79/mach-fritz450e.c:126: .reset_gpio =
FRITZ450E_GPIO_PHY_RESET,

Can anyone enlighten me?

Best

Adrian
