From: Frank Wang <redacted> Move SSC modulation deviation into private config of clock - 24M: 0x00d4[5:0] = 0x30 - 26M: 0x00d4[5:0] = 0x33 Signed-off-by: Frank Wang <redacted> [Taken over from rockchip's kernel tree; register 0x00d4 is not described in the TRM] Reviewed-by: Neil Armstrong <neil.armstrong@linaro.org> Signed-off-by: Sebastian Reichel <redacted> --- drivers/phy/rockchip/phy-rockchip-usbdp.c | 8 ++++---- 1 file changed, 4 insertions(+), 4 deletions(-)
