Subject: [PATCH v2 7/7] ARM: dts: bcm63148: Add I2C block
Date: Wed, 18 Feb 2026 10:30:54 +0100 [thread overview]
Message-ID: <20260218-bcmbca-i2c-dts-v2-7-5373ef82c50c@kernel.org> (raw)
In-Reply-To: <20260218-bcmbca-i2c-dts-v2-0-5373ef82c50c@kernel.org>
The BCM63148 has a brcmper I2C block.
The peripheral range needs to be extended to accommodate
it. The Boot LUT is at offset + 0x10000 so extend it to
cover at least that too, 128 KB.
INTERRUPT_ID_I2C is at (ISR_TABLE3_OFFSET + 19) = 96+19 = 115,
convert back to SPI IRQ 115-32 = 83.
