Subject[RFC 00/12] Misc patches for QCOM clocks
Date
This patch series does the miscellaneous changes in different
types of Qualcomm clock nodes which are required for IPQ8074 SoC.
Following are the major changes in IPQ8074 for which the existing
code does not have support.

1. Some of the IPQ8074 RCG2 has CFG_RCGR at offset 8 from
CMD_RCGR instead of offset 4. Following are the register
offsets of UBI RCG2 in Qualcomm IPQ8074.

GCC_NSS_UBI0_CMD_RCGR: 0x1868100
GCC_NSS_UBI0_CFG_RCGR: 0x1868108

2. It uses Brammo and Huayra PLL’s for which the support is
not available in existing alpha PLL code.
3. Its APSS and UBI PLL offsets are different although both
are Huayra PLLs.
4. Some of the its divider should not be changed during
frequency change.

These code changes are generic and it can be used by other
Qualcomm SoCs. The major change is taking the register offsets
from PLL and RCG2 clock node. Since this patch series is
touching common code so this has been raised as RFC.

Abhishek Sahu (12):
clk: qcom: support for register offsets from rcg2 clock node
clk: qcom: flag for 64 bit CONFIG_CTL
clk: qcom: support for alpha mode configuration
clk: qcom: use offset from alpha pll node
clk: qcom: fix 16 bit alpha support calculation
Clk: qcom: support for dynamic updating the PLL
clk: qcom: add flag for VCO operation
clk: qcom: support for Huayra PLL
clk: qcom: support for Brammo PLL
clk: qcom: add read-only divider operations
clk: qcom: add read-only alpha pll post divider operations
clk: qcom: add parent map for regmap mux
