Subject: [PATCH v4 10/14] ARM: dts: dra7-evm: Add wilink8 wlan support
Date: Fri, 27 Apr 2018 17:39:01 +0530	[thread overview]
Message-ID: <20180427120905.3665-11-kishon@ti.com> (raw)
In-Reply-To: <20180427120905.3665-1-kishon@ti.com>

From: Hari Nagalla <hnagalla@ti.com>

The wilink module is a combo wireless connectivity sdio
card based on Texas Instrument's wl18xx solution. It is a
4-wire, 1.8V, embedded sdio wlan device with an external
irq line and is power-controlled by a gpio-based fixed
regulator.

Add pinmux configuration and IODelay values for MMC4.
On dra7-evm, MMC4 is used for connecting to wilink module.
