Subject: ARM: rockchip: select ARCH_DMA_ADDR_T_64BIT for LPAE
X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=58ed5e5733b293f03a302612d395ac747021b946;p=GitHub%2Fmoto-9609%2Fandroid_kernel_motorola_exynos9610.git

ARM: rockchip: select ARCH_DMA_ADDR_T_64BIT for LPAE

Rockchip RK3288 has some 64-bit capable DMA and therefore needs
dma_addr_t to be a 64-bit size. One user is the Mali GPU.
