Subject: [PATCH] ARM: at91: at91sam9x5: sets NPCS0 (PA14) back to GPIO
Date: Thu, 24 Jul 2014 15:38:24 +0200 [thread overview]
Message-ID: <53D10C50.50305@aksignal.cz> (raw)
In-Reply-To: <1405074175-22444-1-git-send-email-voice.shen@atmel.com>
After ROMBOOT tries boot from flash on SPI0 NPCS0, this NPCS0 (PA14) remains set to PERIPH_A.
Because of that, this pin is unusable to something else.
This patch sets it back to GPIO.
