[PATCH 6.0 451/862] arm64: dts: exynos: fix polarity of "enable" line of NFC chip in TM2

[Greg Kroah-Hartman]

From: Dmitry Torokhov <dmitry.torokhov@xxxxxxxxx>

[ Upstream commit bd1a665a01b4d65fd8dc6fece4b376fa5c8c55bb ]

According to s3fwrn5 driver code the "enable" GPIO line is driven "high"
when chip is not in use (mode is S3FWRN5_MODE_COLD), and is driven "low"
when chip is in use.

s3fwrn5_phy_power_ctrl():

	...
	gpio_set_value(phy->gpio_en, 1);
	...
	if (mode != S3FWRN5_MODE_COLD) {
		msleep(S3FWRN5_EN_WAIT_TIME);
		gpio_set_value(phy->gpio_en, 0);
		msleep(S3FWRN5_EN_WAIT_TIME);
	}

Therefore the line described by "en-gpios" property should be annotated
as "active low".

The wakeup gpio appears to have correct polarity (active high).
