The Hawi SoC is a derivative of Kaanapali with an updated camera
clock controller (CAMCC). While the overall block structure is
similar, Hawi's CAMCC differs from Kaanapali in the following ways:
- Uses Taycan EHA-T PLLs instead of Taycan EKO-T PLLs, with an
additional ninth PLL (PLL8)
- Adds a SQPF block with its own GDSC, AHB clock, and BCR reset
- Adds a CX GDSC (CAM_CC_TITAN_TOP_CX_GDSC) for the camera subsystem
- Expands ICP from one to two instances (ICP_0 and ICP_1)
Due to these differences, Hawi requires its own 'qcom,hawi-camcc'
compatible string and a dedicated driver.
The BIST MCLK clock controller (CAMBISTMCLKCC) is unchanged between
Hawi and Kaanapali, allowing the existing Kaanapali CAMBISTMCLKCC
driver to support both SoCs without modification.
Add the 'qcom,hawi-camcc' and 'qcom,hawi-cambistmclkcc' compatible
strings to the binding, along with the corresponding clock ID header.
