Subject: [PATCH v2] drm/etnaviv: don't truncate physical page address
Date: Fri, 16 Sep 2022 12:40:31 +0200	[thread overview]
Message-ID: <20220916104031.1843306-1-l.stach@pengutronix.de> (raw)

While the interface for the MMU mapping takes phys_addr_t to hold a
full 64bit address when necessary and MMUv2 is able to map physical
addresses with up to 40bit, etnaviv_iommu_map() truncates the address
to 32bits. Fix this by using the correct type.

Fixes: 931e97f3afd8 ("drm/etnaviv: mmuv2: support 40 bit phys address")

v2: Use proper printk format specifier.
