2019-07-25soc/rockchip/rk3399: Use 64 bits in multiplicationJacob Garber
This multiplication is of the form u64 = u32 * u32. Despite being stored in a 64 bit variable, the intermediate value is still calculated using 32 bit math, which could possibly overflow. Cast one of the variables to a u64 to ensure it uses 64 bit math instead to avoid this.

2018-01-29rockchip/rk3399: Support LONG_WRITE type in MIPI DSILin Huang
Some panels need to transfer initial code, and some of them will be over 3 bytes, so support LONG_WRITE type in driver. Refactor mipi dsi transfer function to support it.

2017-11-28rockchip/rk3399: mipi: properly configure PHY timingLin Huang
These values are specified as constant time periods but the PHY configuration is in terms of the current lane byte clock so using constant values guarantees that the timings will be outside the specification with some display configurations. Derive the necessary configuration from the byte clock in order to ensure that the PHY configuration is correct.

This patch correct Feedback divider setting: 1.
