Subject: [PATCH 02/17] dts: Create a dtsi for BCM2835/6/7 specific
|
|
configuration
|
|
|
|
This follows a similar change in kernel[1]. The change moves
|
|
configuration that was not applicable for all bcm2835/6/7/8 out of
|
|
bcm283x.dtsi. The new file is bcm2835-common.dtsi and contains
|
|
conifguration that is common for bcm2835/6/7 (not bcm2838).
