If SATA PHY is accessing SATA registers, disabling the clock will most likely lock-up the SoC.

The BG2Q has an AHCI SATA controller. Add the corresponding nodes (AHCI, PHY) into its device tree. Signed-off-by: Antoine Ténart <antoine.tenart@free-electrons.com> --- arch/arm/boot/dts/berlin2q.dtsi | 28 ++++++++++++++++++++++++++++ 1 file changed, 28 insertions(+)
