Subject: [RESEND][PATCH 2/2] memory: tegra: Correct num_tlb_lines for tegra210
Date: Thu, 17 Sep 2020 04:31:55 -0700 [thread overview]
Message-ID: <20200917113155.13438-3-nicoleotsuka@gmail.com> (raw)
In-Reply-To: <20200917113155.13438-1-nicoleotsuka@gmail.com>
According to Tegra210 TRM, the default value of TLB_ACTIVE_LINES
field of register MC_SMMU_TLB_CONFIG_0 is 0x30. So num_tlb_lines
should be 48 (0x30) rather than 32 (0x20).
