Subject: [PATCH 3/3] ARM64: dts: meson: fix clock source of the pclk for UART_AO
Date: Mon, 26 Mar 2018 16:18:09 +0800 [thread overview]
Message-ID: <20180326081809.49493-4-yixun.lan@amlogic.com> (raw)
In-Reply-To: <20180326081809.49493-1-yixun.lan@amlogic.com>
>From the hardware perspective, the clk81 is the parent of
the UART_AO clocks. So it make more sense to mark
the CLKID_AO_UART1/2 as the pclk.
Previous we had flag=CLK_IGNORE_UNUSED in AO clock driver.
This will make kernel leave clock as it is while bootloader
set the clock on.
