[PATCH v3 5/9] media: staging: rkisp1: remove unecessary clocks

From: Helen Koike
Date: Thu Jul 02 2020 - 12:54:52 EST


aclk_isp_wrap is a child of aclk_isp, and hclk_isp_wrap is a child of
hclk_isp, thus we can remove parents from the list, with the goal to
cleanup the dt-bindings and remove it from staging.

For reference, this is the isp clock topology:

xin24m
pll_npll
npll
clk_isp1
clk_isp0
pll_cpll
cpll
aclk_isp1
aclk_isp1_noc
hclk_isp1
aclk_isp1_wrapper
hclk_isp1_noc
aclk_isp0
hclk_isp1_wrapper
aclk_isp0_wrapper
aclk_isp0_noc
hclk_isp0
hclk_isp0_wrapper
hclk_isp0_noc
pclkin_isp1_wrapper
