[PATCH v2 0/7] fix and optimize some clock configuration for the RK3399 platfom

[PATCH v2 0/7] fix and optimize some clock configuration for the RK3399 platfom

[Xing Zheng]

Hi:
  In the development work, we found that some of the previous
incorrect clock configuration on the RK3399 platform, we should
fix and optimize them.

Changes in v2:
- add the patch "fix incorrect parent for rk3399's {c,g}pll_aclk_perihp_src"

Elaine Zhang (1):
  clk: rockchip: rk3399: delete the CLK_IGNORE_UNUSED for aclk_pcie

Xing Zheng (6):
  clk: rockchip: rk3399: export USBPHYx_480M_SRC clock IDs
  clk: rockchip: rk3399: export 480M_SRC clock id for usbphy0/usbphy1
  clk: rockchip: rk3399: fix incorrect parent for rk3399's {c,
    g}pll_aclk_perihp_src
  clk: rockchip: rk3399: fix incorrect aclk_emmc source gate bits
  clk: rockchip: rk3399: add 65MHz and 106.5MHz clocks for HDMI
  clk: rockchip: rk3399: Add support frac mode frequencies

There was a typo, swapping 'c' <--> 'g'.

And sorry to refer incorrect clock diagram, we double check it that
the bits configuration of the Xpll_aclk_perihp_src need to be fixed:
bit 1 - shows aclk_perihp_cpll_src_en
bit 0 - shows aclk_perihp_gpll_src_en

[PATCH v2 7/7] clk: rockchip: rk3399: Add support frac mode frequencies

[Xing Zheng]

We need to support various display resolutions for external
display devices like HDMI/DP, the frac mode can help us to
acquire almost any frequencies, and need higher VCOs to reduce
clock jitters.
