[PATCH 02/10] clk: qcom: gcc-sm8450: Add SM8475 support
From: Danila Tikhonov
Date: Wed Jul 31 2024 - 14:00:46 EST
Add support to the SM8475 global clock controller by extending the
SM8450 global clock controller, which is almost identical but has some
minor differences.

Say Y if you want to use peripheral devices such as UART,
SPI, I2C, USB, SD/UFS, PCIe etc.
