[PATCH] ARM: dts: Fix booting on Rinato market device

From: Krzysztof Kozlowski
Date: Fri Nov 07 2014 - 06:44:40 EST


The bootloader on market Rinato (Gear 2) device checks for revision in
compatible field of DTB. If it is not present or lower than required
then booting fails with: "Could not do normal boot. (no DTB found)".

Log of bootloader in case of failure:
h/w: revision = 0x06
h/w: schematic = SM-R380_Rev0.5_Final_0205
date = 2000/01/01 12:00:21 (UTC)
cmu_div:4, div:5, src_clk:800000000, pixel_clk:31860720
load_kernel: loading boot image from 57344.. (BOOT)
load_kernel: found zImage, size: 0x3267e8
0xbc Error!
Verify_Binary_Signature: failed.
pit_check_signature (BOOT) invalid.
load_kernel: found custom kernel (ret:-2147483647)
No need to update kernel type.
Detected board: samsung,rinato-rev06
Could not do normal boot. (no DTB found)
: Entering usb mode for SM-R380_EUR_XX (65535)..

Add a "rev06" suffix to compatible to satisfy the bootloader.
