Subject: [PATCH 4/5] arm64: dts: exynos: gs101: use correct clocks for usi_uart
Date: Sat, 27 Jan 2024 00:35:53 +0000 [thread overview]
Message-ID: <20240127003607.501086-5-andre.draszik@linaro.org> (raw)
In-Reply-To: <20240127003607.501086-1-andre.draszik@linaro.org>
Wrong pclk clocks have been used in this usi8 instance here. For USI
and UART, we need the ipclk and pclk, where pclk is the bus clock.
Without it, nothing can work.
It is unclear what exactly is using USI0_UART_CLK, but it is not
required for the IP to be operational at this stage, while pclk is.
This also brings the DT in line with the clock names expected by the
usi and uart drivers.
Update the DTSI accordingly.
Fixes: d97b6c902a40 ("arm64: dts: exynos: gs101: update USI UART to use peric0 clocks")
