Subject: [PATCH 2/2] ARM: bcm2835: dts: fix uart0/uart1 pins
Date: Sun, 29 Jan 2017 21:53:11 +0200	[thread overview]
Message-ID: <e0f527a24b0048daba88ef36d5324245e003111c.1485719591.git.baruch@tkos.co.il> (raw)
In-Reply-To: <9290fa9eed6b5ff1c5c96b9dac41eca286b7eef9.1485719591.git.baruch@tkos.co.il>

According to the BCM2835 ARM Peripherals document uart1 doesn't map to pins
36-39, but uart0 does.

Also, split into separate Rx/Tx and CST/RTS groups to match other uart nodes.

Fixes: 21ff843931b ("ARM: dts: bcm283x: Define standard pinctrl groups in the gpio node.")
