[ Upstream commit 737e7610b545cc901a9696083c1824a7104b8d1b ]
The 3.10 vendor kernel defines the following GPU 20 interrupt lines: #define INT_MALI_GP AM_IRQ(160) #define INT_MALI_GP_MMU AM_IRQ(161) #define INT_MALI_PP AM_IRQ(162) #define INT_MALI_PMU AM_IRQ(163) #define INT_MALI_PP0 AM_IRQ(164) #define INT_MALI_PP0_MMU AM_IRQ(165) #define INT_MALI_PP1 AM_IRQ(166) #define INT_MALI_PP1_MMU AM_IRQ(167) #define INT_MALI_PP2 AM_IRQ(168) #define INT_MALI_PP2_MMU AM_IRQ(169) #define INT_MALI_PP3 AM_IRQ(170) #define INT_MALI_PP3_MMU AM_IRQ(171) #define INT_MALI_PP4 AM_IRQ(172) #define INT_MALI_PP4_MMU AM_IRQ(173) #define INT_MALI_PP5 AM_IRQ(174) #define INT_MALI_PP5_MMU AM_IRQ(175) #define INT_MALI_PP6 AM_IRQ(176) #define INT_MALI_PP6_MMU AM_IRQ(177) #define INT_MALI_PP7 AM_IRQ(178) #define INT_MALI_PP7_MMU AM_IRQ(179)
However, the driver from the 3.10 vendor kernel does not use the following four interrupt lines: - INT_MALI_PP3 - INT_MALI_PP3_MMU - INT_MALI_PP7 - INT_MALI_PP7_MMU
Drop the "pp3" and "ppmmu3" interrupt lines. This is also important because there is no matching entry in interrupt-names for it (meaning the "pp2" interrupt is actually assigned to the "pp3" interrupt line).
