stable inclusion form stable-v5.10.82 commit 17dfbe1b2f4ea2babc2b2807dc28ad2ba6fe7971 bugzilla: 185877 https://gitee.com/openeuler/kernel/issues/I4QU6V
Reference: https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git/commit/?id=...
--------------------------------
[ Upstream commit e8f67482e5a4bc8d0b65d606d08cb60ee123b468 ]
BCM63XX selects HAVE_LEGACY_CLK but does not provide/support clk_get_parent(), so add a simple implementation of that function so that callers of it will build without errors.
Fixes these build errors:
mips-linux-ld: drivers/iio/adc/ingenic-adc.o: in function `jz4770_adc_init_clk_div': ingenic-adc.c:(.text+0xe4): undefined reference to `clk_get_parent' mips-linux-ld: drivers/iio/adc/ingenic-adc.o: in function `jz4725b_adc_init_clk_div': ingenic-adc.c:(.text+0x1b8): undefined reference to `clk_get_parent'
