In-Reply-To: <1431978219-14226-1-git-send-email-eric@anholt.net> References: <1431978219-14226-1-git-send-email-eric@anholt.net> Message-ID: <1431978219-14226-8-git-send-email-eric@anholt.net> To: linux-arm-kernel@lists.infradead.org List-Id: linux-arm-kernel.lists.infradead.org We were previously using a fixed clock declared in the 2835 DT, but it's actually the core clock, and it might not be the same if you had adjusted it using the firmware's config.txt. Signed-off-by: Eric Anholt --- This is the only patch in the series I haven't really tested, since I don't have any SPI devices. arch/arm/boot/dts/bcm2835-rpi.dtsi | 4 ++++ 1 file changed, 4 insertions(+) diff --git a/arch/arm/boot/dts/bcm2835-rpi.dtsi b/arch/arm/boot/dts/bcm2835-rpi.dtsi index 53285a3..994c8e7 100644 --- a/arch/arm/boot/dts/bcm2835-rpi.dtsi +++ b/arch/arm/boot/dts/bcm2835-rpi.dtsi @@ -69,3 +69,7 @@ <&firmware_clocks RPI_CLOCK_CORE>; clock-names = "uartclk", "apb_pclk"; }; + +&spi { + clocks = <&firmware_clocks RPI_CLOCK_CORE>; +}; -- 2.1.4
