ARM: EXYNOS: PL330 MDMA1 fix for revision 0 of Exynos4210 SOC
Commit 8214513
("ARM: EXYNOS: fix address for EXYNOS4 MDMA1")
changed EXYNOS specific setup of PL330 DMA engine to use 'non-secure'
mdma1 address instead of 'secure' one (from 0x12840000 to 0x12850000)
to fix issue with some Exynos4212 SOCs. Unfortunately it brakes
PL330 setup for revision 0 of Exynos4210 SOC (mdma1 device cannot
be found at 'non-secure' address):
[ 0.566245] dma-pl330 dma-pl330.2: PERIPH_ID 0x0, PCELL_ID 0x0 !
[ 0.566278] dma-pl330: probe of dma-pl330.2 failed with error -22
Fix it by using 'secure' mdma1 address on Exynos4210 revision 0 SOC.
